Infrastructure efficiency has improved significantly with quick server provisioning, though physical to virtual migrations need a streamlined in-house tool

From my experience with Nutanix Cloud Infrastructure (NCI), there is one area that needs improvement. When moving a critical infrastructure from a physical machine to Nutanix Cloud Infrastructure (NCI), we currently have to use a third-party tool to convert the physical machine to a VM. We have to use VMware converter to perform this conversion before moving it to Nutanix Cloud Infrastructure (NCI). I would suggest that Nutanix Cloud Infrastructure (NCI) should develop their own P2V (physical to VM) tools instead of requiring users to rely on third-party solutions.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The scalability, performance, and licensing model are the most valuable features."

"If you are looking for flexibility, space-saving, power-saving, and the best ROI, this is the solution to use."

"My advice to anyone considering Nutanix Acropolis AOS is that you won't go wrong."

"The best feature of Nutanix Acropolis AOS is the central management of all of our resources. Additionally, it is easy to use"

"Now that we have virtualization, with its simple configuration and installation, I can run the different platforms on it."

"The management interface of this solution is great."

"I would advise others this solution is simple to use, it is good."

"It has been stable so far."

More Nutanix Cloud Infrastructure (NCI) pros

"There are many services that can be directly used which are not available in VMware."

"It was a very flexible and scalable solution. It was very useful because we were not dependent on a single vendor's solution. Increasing the number of machines or changing the hardware configuration was very easy."

"Administrators are very comfortable with the functionality and services OpenStack offers."

"OpenStack allowed for mass uploading of images to Akamai cloud services."

"Apart from the main features, I really appreciate OpenStack's microservices architecture and its flexibility for deployment with different tools."

"I like its integration with GitLab and its simplicity. OpenStack has a lot of third-party libraries that it uses."

"The most valuable feature is the customization. With the customization you can really give the customers what they want."

"The initial setup isn't too difficult."

More Rackspace OpenStack pros

Cons

"The licenses for Nutanix are very complicated."

"I believe that improvements could be made in regards to the DR in addition to deduplication and integration with others platforms. They also do not offer opportunities for network virtualization so it would be nice to see that in the future."

"I would like to see them utilize the spare storage that they use as a redundant space. I feel that now a lot of resources are wasted just for standby purposes because we are using data protection."

"As of now, Acropolis and VMware cannot talk to each other. Until we have some kind of interface, it would be much better for Nutanix if they built an interface which can talk. Otherwise, if I have a VMware stack and I already have a Nutanix stack, I create containers, I create clusters on VMware, I create clusters on Nutanix. All of these clusters cannot talk to each other. Then it has to be then subverted as a parallel execution. What happens then is that I have to work in two different environments within my data center. Practically, they are two different data centers but physically and logically, they are one. If they cannot talk to each other that creates a lot of issues. That is something which Nutanix has to develop because for Nutanix it is very simple. For example, Oracle is using a function called GoldenGate. They have a feature called GoldenGate which allows them to talk to various different environments which must really help."

"If they cannot talk to each other that creates a lot of issues."

"Could have better visibility with the main OEM backup integrators."

"I think that there are several areas that they can improve slightly, including the mail servers, the application servers, and perhaps even the database servers."

"The one note of improvement I have for Nutanix is that the installation should be easier."

More Nutanix Cloud Infrastructure (NCI) cons

"It could use more examples in different languages (API use cases)."

"The pricing of Rackspace is quite high in the Vietnam market."

"The seamless integration between MySQL services and the rabbitMQ database can be revised during the debugging phase."

"It should have a single dashboard for cloud management and on-premises systems"

"The line migration is a problem."

"So for the main stability, there have been a couple of issues that I've experienced."

"VMware has a side-to-side replication feature, which is still more mature than Rackspace OpenStack's which can't be used in a production environment."

"As a beginner, I find some difficulties in understanding Rackspace OpenStack, as it can be complex without a foundational grasp of cloud and networking concepts."

More Rackspace OpenStack cons

Pricing and Cost Advice

"The setup cost, pricing, and licensing are very competitive and TCO is very low compared to three-tier solutions."

"The overall cost depends on the contract of each customer and the discounts they have, but the price for the three-tier architecture can be slightly lower."

"It is less expensive than the VMware alternative."

"There is a license required for this solution and my clients usually purchase a two-year license with extended support. The price of the solution could be reduced, it is more expensive than competitors."

"The price of the solution could improve. Nutanix has recently changed its pricing model from perpetual to subscription. They have identified there are challenges with the pricing model."

"The basic license that comes with the box allows basic virtualization features but advanced automation features would require an upgrade of licenses."

"Nutanix Cloud Infrastructure's pricing is higher now."

"My advice is to get the ultimate license, as it is worth it."

More Nutanix Cloud Infrastructure (NCI) pricing and cost advice

"The pricing is low."

"I use it as an open-source tool."
