Nutanix Cloud Infrastructure (NCI) Reviews

Any single server or one-plus-one server is very difficult to manage if there is hardware failure. But with this solution, the transition is seamless because a 10-plus-one redundancy is built into the system.

With the click of a button, we can migrate the services to other servers. We have never had any downtime and we are a 24/7 operation. Production has continued,

Nutanix Cloud Infrastructure also helps us to optimize power utilization and the rack space used in the data center, resulting in overall energy savings.

These were immediate advantages because, eight to 10 years back, this was a new technology. We tried it with our less critical operations, and we slowly introduced more production-critical workloads.

Also, we were using Active Directory and other SQL databases on individual servers. We were able to consolidate them into a single database. That helps with ease of operations and enables taking backups from a single place. We migrated all our standard database structures and we don't need a cluster mechanism because the cluster or failover mechanism is built into the Nutanix architecture.

It gives us a single dashboard to control multiple sites and multiple zones. It helps to do things on a single platform and data sharing is quite easy. The network and the security are easy to manage.

I would like to see more Kubernetes and container-related workflows and multiple cloud-partner management. I would also like to see how they will synergize all these AI/ML functionalities that are available on other platforms. We need to see those intelligent functionalities included.

I've been working with Nutanix Cloud Infrastructure (NCI) for almost eight years.

It's quite stable. We have never had any downtime.

For any on-prem or hybrid solution, it is highly scalable and easy to manage. We expect to increase our usage of NCI.

We used VMware which was helpful for a lot of things, but in terms of the scalability, the main thing was the central storage architecture. That became a bottleneck. Scaling up the storage was a little difficult. When it came to usability and ease of management, we decided to go with Nutanix.

The initial deployment was straightforward. It took less than a week, including doing the application migration. It was quite easy to create an image of the existing bare-metal infrastructure and migrate that image to the new solution. We always did it on a weekend or during a window of downtime at night.

We have it deployed in a single data center and we have under 100 users.

There is minimal maintenance. Upgrading is quite easy. Adding compute or storage on demand is also quite easy because we get a compute-only node or a storage-only node and add the nodes to meet requests for the CPU or storage requirements. These tasks are managed by the IT infrastructure team.

We used a reseller, and we had four or five people involved from IT and database administration.

The primary objective was to reduce downtime. That means we can't assess ROI  in terms of monetary value. It is more an issue of reliability.

It is slightly more expensive compared to a standard, on-prem, bare-metal configuration. There is about a 30 percent overhead there. That is the pricing in the Indian scenario.

The single dashboard is an additional cost option.

VMware is the only competition I can think of.

A standard SAN solution is quite fast in terms of storage, if you size it well, but the main challenge with a SAN solution will be scaling up. If it's not sized and planned well, it will be a big challenge and we would need to invest huge money in the SAN architecture.

It is quite comprehensive, all the toolsets are available, so there aren't many limitations. If you are looking for hybrid or on-prem virtualization, Nutanix is the preferred choice. The things that stand out are the scalability and ease of use. For a CIO, what is relevant is how scalable and reliable the solution is.

We have four Nutanix clusters at different sites and we are using it as our hyper-converged infrastructure solution.

By using more than one cluster, if any node is down, the VMs can be moved to a remaining node, and that helps us to work without any downtime. A node can be moved, online, to another node, which minimizes downtime as much as possible.

Flow Network Security for microsegmentation also helps in maintaining security. For example, we can protect servers with policies between an application server and a database server.

Previously we had our own storage, stand-alone servers, and stand-alone network. For any new project, it would take us at least six months until we could provide a new server. Now, when we have a new product, we can avoid that long wait and provide a server in hours. 

We have also moved all our servers to Nutanix and have been able to eliminate our legacy servers and infrastructure.

And it keeps our IT staff informed by email regarding any error or alert. They log in and get a full view of all our servers, including memory, storage, and CPU usage. It helps our IT staff to be more productive.

The most valuable aspect of Nutanix is the performance of the storage, which is excellent. And controlling compute, storage, the network, and security all together in one box is very efficient for us. It gives us a single platform to manage all our infrastructure.

It's so easy to configure anything on Nutanix. We have had Nutanix for more than five years and all our products are on it. It's really easy to manage them. We can monitor our servers and get notified if there is any issue with a server and correct it before a problem happens.

They need to improve the look and feel of the interface. The functionality is fine, but the appearance could be better.

We have been using Nutanix Cloud Infrastructure (NCI) for five years.

It's very stable. We haven't had any issues with Nutanix.

It's so easy to scale out or scale in our infrastructure.

If we have any issue, we contact their support and they solve it within the SLA time. They are very helpful and respond to us as soon as possible.

Positive

We had another solution, VxRail. We did a comparison between Dell VxRail and Nutanix and we found that Nutanix is more compatible with our organization.

The initial deployment was easy.

We installed Nutanix in multiple locations: at three sites in Egypt and one in Indonesia. We have the main site and a DR site in Egypt. There are three people on our IT team who administer the four clusters.

We have had to do maintenance on the hard disk two times in the last four years. And upgrading our Nutanix servers takes one click. We have upgraded our firmware and AHV and it is so easy. It's also very easy to add compute and storage. We just click to expand a cluster and add new nodes.

Nutanix has helped us to reduce the cost of the operations in our company.

The price of Nutanix is lower than other products.

My advice is to purchase Nutanix. It will help with your infrastructure.

One of the municipalities in Istanbul uses it for virtual servers in their data centers. They have about 150 virtual servers.

Before Nutanix, our customers were using VMware with external storage from HPE, IBM, and others. They have been able to consolidate all the external data in the Nutanix clusters. That has reduced their server footprint as well as power consumption, which is important for the environment.

Nutanix has a very rich feature set and product solutions that are good for our customers. Instead of using different types of solutions, Nutanix covers all of them. That is a very big advantage. Often, to get the best feature sets, you need a lot of vendors, each one having different products. Vendor management, in that case, is difficult. But with Nutanix, everything comes from the same vendor, making vendor management easy.

There are a lot of features but the main ones are related to storage. Nutanix provides a software-defined storage solution for virtual servers.

It also has a lot of available services when it comes to infrastructure, and our customers use most of them. It provides a redundant set of data. The snapshots, cloning, and replication are all effective in helping to reduce downtime. It can replicate cluster data for disaster recovery and it provides high availability in case a node or a disk fails. Nutanix's availability feature set is bigger than that of other solutions.

They could improve the graphical user interface. 

I have been working with Nutanix Cloud Infrastructure for two years.

It is a robust and very stable solution.

It's also very scalable.

They are very responsive and provide quick resolutions.

Positive

The setup is automated and very easy. The time it takes to deploy depends on the project, but in most cases it will take several hours. One person is enough to do the deployment.

Our deployment is on a private cloud, but you can use public cloud because Nutanix has agreements with Azure, Amazon, and other public cloud services.

In terms of maintenance, it's easy to update Nutanix because you can download hardware/firmware upgrade sets and deploy all of them. I worked with VMware for at least 15 years. You can upgrade VMware products, but you can't upgrade hardware firmware with VMware. You need to contact the hardware vendor or support sites. They are separate things. But with Nutanix, you can deploy hardware firmware and software updates together.

It is also very easy to add compute and storage on demand with Nutanix. You can put a disk into an empty slot and, in several minutes, it's working.

In addition, you can get training very easily with Nutanix University and there are certifications. When you complete Nutanix University courses, they provide free certification exams. If I can compare it with VMware, I attended a conference and I passed a VMware certificate exam, but they didn't give me a certificate and said I had to attend a VMware class that costs about $2,500.

Our customers see ROI with Nutanix. Using it, they have very efficient infrastructures. They benefit from the reduced footprint, lower power consumption, and easy management. It also gives them efficient data storage with compression, deduplication, and easy snapshot features to reduce the data footprint. All of these things make it worth the licensing costs.

It's a bit expensive, but it's worth it.

Nutanix has a lot of products and solutions to provide a complete cloud-integrated infrastructure. Our customers use some of them, but not all of them.

My advice is to use Nutanix, without hesitation.

Our client was using ESXi and Microsoft Hyper-V clustering, but patching and upgrading ESXi and Microsoft Hyper-V clusters was very tedious. That was their pain area. We understood their pain area and positioned Nutanix there. Instead of the orthodox three-tier architecture, they chose Nutanix. The benefit of Nutanix is that there is a very simple upgrade path. It is done with a click. The storage part is simple. It has a very easy UI, which is a USP of Nutanix. The client is very happy.

We have multiple such clients, and our clients are happy with it. For more than 10 clients, I myself have done the deployment of the Nutanix cluster. One of them had a cluster with 24 nodes.

In a single pane of glass, you get all the insights about your infrastructure. Earlier, in the orthodox three-tier architecture, you had multiple UIs. You also needed multiple expertise to take care of things. It used to take more time to troubleshoot and identify where exactly the issue was. You had to get your analytics, get your logs, and then troubleshoot. All this is avoided with the Nutanix architecture. It is hardware agnostic. For example, if an organization has a contract for the HPE hardware or they have an HPE footprint or a Dell footprint in their DC, they can go with that particular hardware and have Nutanix on top of it. Nutanix does not force you to buy only Nutanix hardware. Other vendors, such as VMware, make you buy their hardware so that their product works fine, but that is not the case with Nutanix. It is hardware agnostic. 

The applications that are run on Nutanix are client-side applications. There are banking or financial applications. They also have Citrix on Nutanix for the virtual desktop. They also have Oracle Database and SAP running properly on the Nutanix hardware or architecture. You can put any application available in the market, such as Oracle Database, MySQL, or NoSQL, and you will not have any slowness or anything like that with that application. Every application works smoothly on the Nutanix platform. It is all tested. 

It is much easier to deploy Nutanix as compared to other solutions. It saves you deployment time. Usually, in a big organization, the planning itself takes around a month. You also need permissions, and then you deploy a solution, so deployment takes time, but that is not the case with Nutanix, which is an advantage. You can get all necessary permissions from your management and then in one day or half a day, you can have your cluster. If you purchase the whole Nutanix portfolio with Nutanix Karbon, Nutanix Flow, and other solutions, deployment is very easy. You can put it into production.

It reduces the downtime. A cluster has multiple nodes in the backend. If you want to upgrade the firmware or you want to upgrade AHV or the hardware, it will do that one by one. It will put some nodes into maintenance mode. It will move some of the virtual machines to other nodes in a cluster. It will take care of the redundancy part. It will take care of your data. The data also gets migrated to those nodes so that it is available locally. You avoid all the hops that are there in the three-tier architecture. It reduces the hops and the time to access your data and gives you the output. All this is taken care of in the Nutanix architecture.

Snapshot is one of the key features that reduce downtime. It gives clients more power to define their RTO and RPO, which is a valuable aspect of the Nutanix architecture. Even in the case of DC/DR, if your DC goes down, you can use the data protection domain and get your DR site up and running. It helps clients achieve their RTO and RPO.

Our clients could realize its benefits in a week. I have worked on more than 10 major deployments. They already had some pain areas, and they wanted to mitigate those areas. We positioned Nutanix and did the PoC, and they were already happy with this solution at the PoC level. We did not have to do deployment and put it in production for them to see its benefits. Based on my experience with Nutanix, in a week's time, they get to know its features and the fact that it works smoothly.

All applications have dependencies. They have some hardware or networking requirements. You need to have the hardware accordingly in your DC. By buying Nutanix, our clients have managed to avoid all these requirements. In a single box, they get all the things, so they do not have to worry about the backend. Their applications work smoothly. They can have any application. They can even have VDI applications such as Citrix VDI or VMware Workspace on top of Nutanix. It supports all the platforms. Our clients are very happy with Nutanix. They do not have to do any hardware upgrades. 

It eliminates the legacy infrastructure. That is the main purpose of HCI. For HCI, Nutanix has been in the number one position for many years. In the three-tier architecture, there used to be a frontend application, a middleware, and a backend database. On the hardware front also, you had to put your servers, your SAN switches, and your backend storage. You had multiple footprints in your DC. You also had more power consumption. Nutanix reduces power consumption, troubleshooting, and maintenance. You do not need a separate team for maintenance. Irrespective of the hardware, you get a single point of contact for any support. All these solutions are consolidated under one roof, which is very beneficial.

We have done the whole DC migration to Nutanix. The client had five to six racks, and they got reduced to two racks by using Nutanix. It takes very less space. It helps to reduce your DC footprint and power consumption. Troubleshooting is very easy. You can also reduce the number of hops. It eliminates the whole process where the front end puts the request to middleware, which then goes to the backend and fetches the data from the storage. You can have your data locally, and then there is just a single hop. You get the output faster. It makes your applications run smoother and faster as well while responding to a request.

Single-click upgrades are the most valuable feature. In the sector in which we work, it is tough to have downtime and arrange firmware upgrades. If something goes wrong, you need to do a fallback or troubleshoot more. That can be totally avoided if you are using Nutanix in the backend for your hypervisor or clustering part. That is one thing.

Another thing is that you get CVMs similar to the number of nodes. CVM handles your backend storage infrastructure. It is underlying your hypervisor. If you have seven nodes, you will get seven CVMs, which is a good thing.

The availability of your data is also valuable. Whenever you shift or migrate your virtual machines inside a cluster, your data also follows that. It creates multiple copies of the data and keeps it ready in the backend for redundancy, which is another good point.

With Nutanix Prism, you get a single dashboard for everything. It shows you whether your data resiliency is okay, whether your nodes are okay, or whether your networking part is okay. It is another USP.

Our client had some old Citrix Xen servers for which there is no direct migration. Nutanix has a move utility for Microsoft Hyper-V clusters or VMware clusters. You can easily migrate them using the move utility, but the Xen clusters cannot be migrated in a simple way. That is the only thing that is lacking, but nowadays, no one uses the Citrix Xen server for their clusters. Everything else is already there. Nutanix keeps on upgrading its hardware's or hypervisor's capability to be able to support new technologies. 

I have been working with Nutanix for more than four years. 

It is quite stable. It is very robust. You can compare it to any old three-tier architecture solution. It is a much better solution. It is a much better approach. 

It is very easy, and it is very scalable. You can scale it vertically and horizontally. It has good scalability. If you have proper resources but only the storage needs to be upgraded, you have that flexibility where you can only purchase a storage node and add it to your cluster. If you want more compute resources, such as more CPU or RAM, you can put more nodes and add them into the cluster. There is no downtime. It is very simple and smooth.

In terms of the end-users, there are more than 3,000 users at a single location. There are multiple locations. There are about four locations in India and then for DR, they have two or three locations. This is basically a banking client, so there are multiple locations where they have put the Nutanix clusters. Even on the DR site, they have Nutanix. They have a six-node cluster where all the data is replicated. It is a multi-site deployment with about 16,000 users.

Their support is also very good. If something goes wrong, they will provide support. You just need to raise a case with their support. They come online and fix the issue as soon as possible and get your production going. 

They also support you at the deployment level. Many times, we faced some challenges because of networking, which plays an important part in deployment. If something is not proper in networking, the deployment does not happen. In such cases, you can raise a case with Nutanix support, and they will help you with the deployment. 

I would rate their support a ten out of ten.

Positive

We did not use a different solution. There was mostly the three-tier architecture, and people used to replace or upgrade at the storage level, networking level, or server level until HCI came into the picture. With HCI, all those things went away. It reduces your DC footprint and gives you a powerful solution. There are different HCI players in the market, such as VMware vSAN and HPE SimpliVity, but wherever we have positioned Nutanix, clients have been happy. We had positioned HPE SimpliVity for a client, but in the next tech refresh, they got it replaced with Nutanix. 

We have had some clients who had their workloads on Azure and for their Oracle Database and SAP environment, they had purchased a Nutanix box from us. They had put their on-premise applications on Nutanix. When they saw those applications working so smoothly, they brought their Azure workload on-premises and bought another Nutanix box. I was a part of that migration.

Nutanix Prism dashboard and one-click upgrades are the points that make Nutanix much better as compared to other solutions. They give you a single pane of glass. The UI is very good. It gives you an experience similar to Azure or AWS UI. You can have all the insights about your hardware in a single pane of glass, and it is very easy for management as well to do regular reporting. They can make fast decisions regarding their futuristic plans.

Most deployments are on a hybrid cloud. Some of the deployments are on a private cloud. Our clients have Azure. They also have Nutanix Cloud.

The initial setup is very simple. You only need to get your foundation VMs set and then you can have it deployed. You need to get your appliance switch and connect all your client's servers to that switch. It is very simple. You can even start it and leave it. It will format all those nodes and make them ready. The networking part is also easy. Whether it is a plain network or you are putting in a VLAN, it is very easy. There are only a few commands, and then you can deploy it. 

For a 24-node cluster, it took us only about six hours, which is not the case with the three-tier architecture. It takes six hours just to plan how to position or get those nodes up and running in production. That is at the very initial level, and then it takes about a month's time to get the node cluster into production. That time is saved with Nutanix. In just six to seven hours, you can get it going in production.

We have a single person for deployment. I myself go to DC and do it. There is one more person to do the rack stacking of all the hardware. A single person is enough to get the clusters ready and put them in production.

In terms of maintenance, it does not require any maintenance that requires any downtime. It is very simple. If some new features get added, it will show them on your dashboard, and then you can upgrade to the newer version.

There is an ROI. With the three-tier architecture, you have to purchase separately for the storage, database, applications, etc. There is a software-layer investment, and then there is a hardware-layer investment. In the software-layer investment, you have to take backups and create a backup infrastructure. You also have to pay for the expertise. You need people for monitoring and taking care of your hardware. You need storage administrators and network administrators. With Nutanix, everything gets consolidated in a single box, and you also save the cost of expertise. There is a good return on investment.

Its licensing is fine. They provide the flexibility to choose from different options. You can go with the standard plan. You can go with the pro or platinum plan. Generally, our clients go with the pro licenses, but if you go for the platinum license, you get even more capabilities. Their starter license is also quite good.

About 95% of our clients go for the pro license, but we also have some clients who do not need enterprise-level features, so they go for the starter or standard license. They do not need to pay anything extra in addition to the standard licensing fee.

Clients usually evaluate a product when they have a pain area, they have a tech refresh, or they want to adopt a new technology. For example, if they are on the old three-tier architecture, they might be curious about HCI. We explain all the benefits of not only the HCI technology but also specifically of Nutanix for HCI. We explain how it addresses their pain area or needs. It has low overheads, so the cost of ownership is also low. They get a robust environment, and it is very easy to handle. It saves time. You do not have to go to DCN, mount storage, deal with SAN switches, etc. All those tasks are time-consuming. The maintenance and configuration take time. Nutanix saves you time. You can fulfill your needs or your clients' needs. The deployment is easy. Sometimes, our clients get astonished at the speed of deployment because they were expecting it to take weeks or months. It is simple but powerful. It is very easy.

Overall, I would rate this solution a 10 out of 10.

I use it for the app DB and infra-related services like Active Directory and file servers. And we run our Verint Enterprise Recording application on the platform.

I set things up for my internal customers who are the end-users.

The number of servers we need has been reduced with NCI's performance, and it reduces the space we need and provides energy savings on top of that. The major benefit is the consolidation of all the physical and VMware servers into the Nutanix AHV platform. That's the baseline of the entire application, the core platform. We no longer use our old HPE and Dell servers. The three-tier architecture has been eliminated. NCI has eliminated that complexity and the costs associated with it.

The architecture of Nutanix is the best, and the virtualization we get, out of the box, is an advantage. Also, dedupe and compression are done natively, inside the platform, so there are no additional licenses. That adds value to it.

In addition, it provides us with a single platform, which is pretty user-friendly, to manage our databases. It doesn't take much to manage the console.

I have been using Nutanix Cloud Infrastructure for about five years.

It's stable. The design means we get an N+1 architecture for node failures. We haven't had any major downtime until now. We are good with the performance.

We have it deployed in multiple locations. It's a distributed architecture.

Their technical support is good, but they do have third-party system integrators. If you get one who is not that great, you will have problems.

Positive

I have worked with Cisco Hyperflex and HPE Simplivity but they don't have software that is equivalent to what Nutanix has. The others are still developing their software.

And Nutanix is far better than a standard SAN solution because it is an all-in-one solution. The read/write speed is far better than in three-tier architecture.

The initial deployment is pretty straightforward. One person can handle it.

There isn't much downtime due to maintenance. And updates are pretty easy, they're just plug-and-play. It's not complex. Adding compute and storage on demand is not a problem for me because my deployment is on-prem.

The ROI is definitely there, based on the consolidation. It reduces the workload footprint. That's the benefit. There aren't too many servers or storage. Nutanix becomes an all-in-one and enables us to accommodate more workloads because it has built-in dedupe and compression.

If they could further reduce the cost, that would be great. I would like to see the cost be less than the equivalent three-tier architecture.

My advice is to get away from the traditional approach and think in forward terms about an HCI model. Nutanix stays ahead in the market.

I haven't seen any drawbacks that would lead me to suggest any improvements to the functionality of NCI.

We use Nutanix Cloud Infrastructure for SQL Server, VDI, general workload, and remote sites.

Nutanix Cloud Infrastructure allowed us to run our BDI a lot more efficiently, and the SQL servers worked up pretty well.

Nutanix Cloud Infrastructure is running all of my business-critical workloads. In my area of the world, we'd have our test dev running on there as well, but we have our core applications that are critical to our operations 24/7 that are running on the solution

Nutanix Cloud Infrastructure's most valuable feature is the flexibility to move the VMs easily, keeping everything together. They really help with the administration side of things. Rather than having a bunch of admins, only a few admins really need to work on it.

Nutanix Cloud Infrastructure's LTS version needs to be more reliable. I've run into too many issues where I've found the bug, and it caused a lot of grief. Nutanix Cloud Infrastructure should do more testing on its LTS version and get that straightened out.

Performance-wise, there is an upper limit on the number of nodes that Prism Element and Prism Central can handle. My two Prism Centrals are scaled for huge workloads, but I struggled with them for a better part of five or six months, where they were timing out on my admins and throwing random errors. The same thing was happening with Prism Element in our larger clusters.

I have been using Nutanix Cloud Infrastructure (NCI) for about ten years.

In the beginning, Nutanix support was top-of-the-line. When I had a problem, I would call them and get a knowledgeable engineer. As of late, it's been a bit of a challenge. I understand that Nutanix is going through some onboarding issues, and it takes a long time to get support people onboard and then get them trained in different situations they will encounter. I think Nutanix does not have enough support staff to care for all its customers.

Positive

We still have some VMware floating around, but it's considerably smaller. I used VMware when it was just VMware hosts, and I could throw that on top of Windows and have VMs.

We switched from VMware to NCI because we wanted to get rid of the three-tier solution. On top of that, our hardware was aging, and we didn't want to increase it. So we just started shrinking it down, and now the old hardware is going to end. We only have around 16 to 17 nodes of VMware left, but everything else is Nutanix.

I was not initially involved in the initial setup or deployment of Nutanix Cloud Infrastructure. It was handled by some admins overseas. However, after those initial VDI clusters, I got more involved with Nutanix and I did the conversions from VMware to Nutanix.

Nutanix Cloud Infrastructure's core licensing needs to have an upper limit since processors are coming out with incredible numbers of cores on them.

I wasn't involved with the original comparison for VDI, but I do recall that solutions like VMware and vSAN were reviewed.

We struggle with software licensing. Everybody's charging by the core. The larger nodes I put in, the more dense I can go, but my licensing costs are still going out.

I really like the whole LCM process in Nutanix Cloud Infrastructure. The whole one-click isn't true. If I go into LCM, do an inventory, and then say patch everything, it will ultimately fail. However, it still works out all right, and we can patch the firmware, drivers, AOS, and all the nodes and do a rolling patch.

When considering NCI, the big thing is considering your entire infrastructure because you go from different vendors and different hardware to handling storage and computing. I think what Nutanix and NCI offer is far better than VMware and Red Hat.

We haven't used much on the security side with Nutanix Cloud Infrastructure. NCI being pre-hardened helps me a lot because that keeps the security team off my back. We do the encryption but don't use the micro-segmentation because that falls to our security team and their firewalls

I have run into problems with Nutanix Cloud Infrastructure, where I have an overabundance of one aspect of the infrastructure and then come up slightly short on another aspect. For example, somebody throws out a server and needs 20 terabytes of space. I buy nodes to fulfill that, but now I'm sitting there with a whole bunch of extra computing. I've tried using just the storage blocks, and I'll never do it again because it's just a waste of licensing.

Overall, I rate Nutanix Cloud Infrastructure (NCI) a six out of ten.

It's an infrastructure product that we mostly use to manage virtual services.

The DR solution in Nutanix has helped us reduce downtime. There are periods of downtime, intentional as well as unintentional, but because we have another site already replicated, our downtime is minimal. The protection policies have the greatest impact in reducing downtime because they help us replicate our data. We're able to do synchronous replication to the remote site and that keeps our machine ready there in case of the need for DR. We just go there and manually power it on.

Nutanix has also helped us free up IT staff. Since I joined this company, I have been the only one managing the solution. Prior to that, there were multiple people involved. The more we move toward Nutanix from vCenter, the more we reduce the number of resources needed. We have freed up almost half of the time we used to need.

There are a lot of things I really like. Perhaps the best part is taking a snapshot of a virtual machine. It's very quick. Another useful part is replication and creating a protection domain: using the protection feature to replicate a machine to a remote site for DR purposes.

I also like Nutanix Flow. It is quite a control mechanism. Other than external firewalls, Nutanix Flow is a good feature to control your traffic and not allow the infra to create two-way contact with any location other than what we specify.

Nutanix Files is also good. It's a little immature but it's still good. I use it more than Windows for files.

And the fact that Nutanix Cloud Infrastructure offers a variety of cloud operating models is also significant for us. Based on the good number of application products that we are using, having multiple options is going to be a benefit for us.

Nutanix Files is a new feature and, as I mentioned, it's immature, although it's a good tool. I have already given this feedback to the engineering team. 

In terms of automation, I know there are ways to do it, but it's not very user-friendly. I've been working for the last three years with Nutanix and I've managed to automate certain things, but it's a somewhat more complex job than it should be. I would like to see more documentation or knowledge base articles. There should also be some pre-built, basic tasks that are shared by Nutanix. That would be helpful. I understand the other side of the picture, that we might hamper production, but some basics that can be shared by Nutanix, for automation, would be good.

There are a lot of things to be worked on. They need to provide more features and certain features that have been released need to be made more mature.

I have been using Nutanix Cloud Infrastructure (NCI) for three years.

There have been one or two bugs reported in the past one and a half years, but other than that, I don't see any issues with the product. It's quite stable.

It is quite easily scaled.

The user base, the people who are benefiting from the product in our organization, is more than 25,000.

As soon we have issues, we report them and their engineering team comes in and works toward a solution. Their technical support is quite good. There are times when I would rate them a 10 out of 10 because there have been engineers who have very good knowledge and who know what they're doing. Other engineers have also tried to do their best.

Earlier, we were using VMware on Nutanix hardware, but for the last year we have been using the Nutanix built-in virtualization technology, Nutanix AHV.

The switch to Nutanix was a decision that came completely from senior management. Initially, we were using a different environment, HPE and then VMware, and then we moved to Nutanix plus VMware. We had licenses available from VMware so we didn't switch to AOS and AHV. But gradually, as the licenses for vCenter expired, we moved to Nutanix AHV. Most of our jobs are done using it.

Our deployment is on-prem. There are discussions happening about moving a part to private cloud, but that's future planning. As of now, it's just on-prem. We have it in multiple locations. It started with South Africa, then we added Germany, Italy, and Singapore. So it's now in multiple data centers.

The initial deployment was slow, to be honest. Before the day of deployment, there were a lot of tasks to be done, prerequisites that had to be fulfilled. But on the day of deployment, it went very smoothly.

We started with keeping vCenter in place, so at first, it was just deploying the hardware and getting the foundation set up done. It didn't take much time, although there was a lot of hardware to add. But it didn't take not more than three or four hours for the actual deployment part.

We did a lot of planning, obviously, even before purchasing the solution, regarding how much hardware and how many resources would be required. That was the most important consideration and, in the backend, there was the networking. We wanted to keep everything on the same network. We added the hardware, the engineers helped to deploy and move things so that everything was on the same network. The virtualization technology itself was the same. It wasn't a very difficult task for us to migrate our VMs from the old hardware to Nutanix hardware. We used the basic migration tools, either vMotion or SvMotion of vCenter. At a later stage, we moved to Nutanix virtualization and we're still migrating but we are now using the Nutanix Move tool.

Nutanix Move is one of the very good tools I've come across. I've been using it quite a lot for the last few months.

There were different tracks and technologies involved in the deployment, including the networking and data center guys, and we needed to have somebody from offshore with access to all the infra. Other than the Nutanix engineers, there were not more than seven or eight people on our side. One person was part of the planning, and one or two people from the networking, server, and virtualization teams. I was part of the virtualization and server teams.

We now have one person dedicated in each region to taking care of the solution. We do regular upgrades of the hardware. It has never incurred any downtime because it's always in the cluster. One of the best parts about Nutanix is that it automatically does all the upgrades and firmware one by one, so we don't have to bother about it. We just initiate it and go for a tea break or lunch. I've done it three times and I haven't found any challenges. It's quite easy and very smooth. It shouldn't be made so easy for such an experienced analyst like me. People like me could lose their jobs, that is how easy it is.

We did come across one scenario two years back in which we had to get additional storage. We are using iSCSI technology and it wasn't that difficult from a technical point of view. We had to purchase additional hardware because the demands from those specific applications were quite high.

Pricing is not my area of expertise. But the license is quite clear to me. It's much clearer than what we had with our previous virtualization environment. The licensing is not complex to understand. I have added some hardware recently and we got the licenses added for it. That was quite simple and very straightforward.

Evaluating other products was not my call, that was also for senior management. I was asked to review Nutanix only. Before we started implementing it or the sign-off happened, I did find the product suitable. When something is new in the market, you have to get used to it and you feel uncomfortable. That's normal for everybody and that happened to me. The only differences were that the GUI did not have certain features that were in vCenter, but I think we have everything covered now. There have been improvements while creating the current version of the product.

I have good friends in the field from different organizations because I have more than 12 years of experience. I've been recommending Nutanix to them. I'm not sure about the cost part, but I'm quite sure about the administrative part.

I have been using Nutanix products, like AOS, HPE, and Prism Central. I am managing a total of seven clusters with Prism Element and one instance with Prism Central.

We did a total deployment to all areas across multiple locations.

My environment is closed. It is not hosted on the internet. It is a dark site. So, if there are any issues, the Nutanix team lacks the ability to remote in because I cannot provide it. 

The Lifecycle Management (LCM) for upgrades is a very fantastic feature that I have observed from Nutanix.

It has centralized management. It is easy for an engineer to manage. More work goes to patching, upgrades, and maintenance. Nutanix is very easy to upgrade. It takes one click. Engineers do not need to spend additional time with Nutanix for upgrades. With one click, it will complete the upgrade and show the results. Other hypervisor solutions are not like this, specifically since you must do all the components one by one.

Nutanix is easy to learn for someone new to the system. It has more flexibility in its handling. If you are familiar with another hypervisor, Nutanix is easy to learn.

There is a cost for us with a Controller VM. For example, if you are purchasing a Nutanix node with 500GB, then 32GB of that node will need to be allocated for Controller VM. Therefore, we need to spend 32GB of RAM for Nutanix, which is not in our production requirements. This is an area that they need to improve.

Most other software comes as an OVF template. These kinds of OVF software templates are only supported in VMware. We technically can customize and use them in Nutanix, but the vendors tell us that there are technical issues that they will not support. So, they either have to improve this or software providers have to provide the proper software for Nutanix supported software.

It is a CentOS-based operating system, but CentOS releases security patches almost every week or every other week. However, Nutanix releases their upgrade at three or four month intervals. According to my organization's SLA, if a critical patch is released during that time, then I need to implement the patches within 30 days. If it is a standard patch, then I need to patch it within 60 days. Since that is my SLA, I cannot meet my SLA for security because Nutanix will not release the upgrade within these 30 days. Between the critical patch release and the Nutanix release, my customers say they are vulnerable and I am accepting the risk while the SLA is breached. Because of this SLA breach, I am rating this solution as eight out of 10.

I have been using it for the last five years.

When we started, it was not that stable. We were facing multiple issues. Now, Nutanix is very stable.

When Nutanix releases their upgrades, I then need to update to the latest upgrade and patch. Once I click the upgrade, it will automatically reboot the AOS one by one. There won't be any service disruption as well.

It is very scalable, especially if you want to expand.

Expansion is very easy. In Nutanix, additional node expansion is very easy. We can spin multiple VMs based on our business requirements very quickly. In this area, it is very good.

There are two engineers managing Nutanix now for four data centers and a lot of customers.

If I am comparing with the other technical support from VMware, the Nutanix server technical support is awesome because they promptly respond. Sometimes, when I call for an engineer, my call will be kept waiting. Other than this, they quickly respond. If the engineers are free, they will attend the call and help us. I would rate them as nine out of 10.

I was using VMware. However, VMware is more costly since Nutanix has cluster and storage management that creates storage free of cost. In the case of VMware, we need to pay the licensing cost for ESXI as well as purchase a separate license for the vSAN for storage consolidation and the HCI configuration. Nutanix is not like that. If you are buying their node, then you only need to pay for the AOS and Prism licensing costs. Cost-wise, Nutanix is very good.

It is very straightforward because there is a foundation option. From the foundation, we mount the devices on the rack and get the network to be connected. That is it. Then, we can use the foundation to configure and push the AOS and the hypervisor. The cluster spins up very quickly. It seems like everything is in a single window. 

Within one day, we can configure a complete cluster. It might not even take a day, but four to five hours to configure it.

Only two people were involved in the deployment. Once it is mounted on the server rack, then it is easy to manage. 

Mounting is a physical activity that took two people. For installation and configuration, we needed only one person. 

AHV is free of cost. If we went for VMware and other hypervisors, we would need to pay for the hypervisor license. Whereas, Nutanix is providing the AHV license for free.

Cost-wise, it is very good. It is like the hypervisor cost is not there. We only need to pay for the system and AOS licenses. 

Updating or configuring the licensing is very easy. We can take the licensed file and use it to update the portal. You download it, then upload it to the cluster. So, the management is very easy.

We only compared VMware and Nutanix, who are the best players in the virtualization area.

We already bought three Lenovo nodes and Nutanix licenses. We are going to expand the solution next month in October.

For most organizations, the first agenda is to look at the cost. If you are comparing Nutanix with any other solutions, Nutanix will be one of the best options. It is very stable now. You can reduce the manpower needed because even a single engineer can manage the maintenance.

Overall, I can rate it as eight out of 10 since there are few limitations.
