VMware NSX Reviews

Have used this solution to implement PAS (PCF) and have also used it for Native Datacenter networking as part of DC refresh.

Have worked on multiple organizations with VMware NSX. It heavily depends on the use case of the solution and how well you are able to use all the features of the product. When using for K8s container platforms or a networking backed for on premises cloud using a CMP(VRA, VIO) then VMware NSX is the best SDN solution but If an organization is not able to use NSX to its full potential (Switching, Routing, Load-balancing, Firewall, IDS, IPS etc.) then its not worth it.

Logical routing, switching are  overall good feature of this SDN solution especially when using CMP's and distributed firewall is very attractive features for micro-segmentation.

In rare situation there are  mismatch in the control plane data and dataplane data i.e. the details and what you actually see on the transport note. This is rare but time consuming to troubleshoot . Additionally, there could be better integration between VMware Cloud Federation (VCF) and NSX-T. Currently, there are some limitations, for example, VCF allows just one overlay transport zone. Also there is not upgrade path from VCF 3(NSX-T 2.5.x) to VCF 4 (NSX-T 3.x)

I have been using the solution for approximately five years.

The stability is good and is getter better after each new release.

The solution is scalable. In the 2.4 version, the controller got merged to create the cluster manager, it now is even better.

The technical support was pretty good, but recently I have had quite a few bad experiences with the support. But that really depends on the account and geographic location and multiple other factors

We have using Cisco ACI  and it is a strong competitor. When you are not using NSX NCP then everything that you need from SDN prospective can be done in Cisco ACI except for the distributed firewall at the vnic level.

The initial installation feels at first a little complex because there are a lot of components, but when you get the understanding after a short time, it is fine.

I was not involved in the purchase of the solution but I hear it is on the expensive side. That is why quite a few companies are moving towards open source because there are multiple solutions such as NginX, that can do the load balancing, and Calico and Flannel can do your logical switching routing.

If there is already VMware environment then it makes sense to use NSX-V, NSX-T as it can be integrated with other VMware automation products. But if approach it towards opensource then other SDN solutions like flannel, Nginx etc. can be evaluated depending on the use case.

If you are wanting to implement this solution I would advise if your project supports it then definitely. You should have a solid use case, the solution is rich in feature sets and you should use all of them. Then only is it worth the money, if you are just buying it for your logical switching and routing, then it is not worth it.

I rate VMware NSX a seven out of ten.

The tool is very useful for cloud providers who need to manage things like Microsoft Enterprise.

The performance is good.

The setup is complex and should be made easier.

I have been using the solution for three years.

It is a stable solution.

It is a scalable solution. Good to scale in and scale out, and add benefits resources. Customers use it across the globe.

The technical support team is dependable because we use the service a lot of time. We opened a lot of cases and it was solved.

The tool's setup is complex. When I deployed it myself, it took less than one day.

We can do many things with NSF; for now, most of the things are the micro security capabilities and features. I recommend the solution. I rate it eight out of ten.

We are using VMware NSX primarily to enable address mechanisms in terms of having to provide the workloads publicly.

In India and similar regions, the CSP faces a significant challenge. The primary issue is related to network address cancellation, which requires private to public IT mapping and the use of the CSP's own IP address space. VMware NSX has been effective in addressing this problem, along with the virtual firewall's ability to function as a network firewall. This has helped to minimize the need for customers to take responsibility for their network security. In these regions, customers expect full-service solutions and do not typically embrace DIY approaches. An analogy for this situation is that if a customer buys a toothbrush from you, they might expect you to brush their teeth for them.

VMware NSX's overlay network is its most valuable feature, as it aligns with any network philosophy and allows for efficient addressing mechanisms. Additionally, the ability to extend the on-premise network into the provider space is beneficial. There are many features provided.

There is room for improvement in VMware NSX's workload management, particularly in the orchestration layer and in managing workloads across multiple clouds.

Additionally, where workload management could be improved is in the ability to federate workloads seamlessly between different control panels. For example, if I am using VMware vCenter as my control panel and have partnered with a non-VMware provider, I should be able to manage my workloads as a customer without having to worry about orchestration. This is an area where there is potential for improvement.

I have been using VMware NSX for approximately eight years.

The scalability of VMware NSX is similar to other solutions. It is scalable.

I rate the scalability of VMware NSX a seven out of ten.

We did not have local support to go to in India. There is no support center here.

I have used Qumulo but we needed to buy a switch for it which was not favorable.

The initial setup of VMware NSX is not complex. If someone has an understanding of how networks work it will be easy. It can take some time to be completed. For example, to configure the solution with the correct commands.

The implementation time can vary depending on the clarity and complexity of the requirements.

When comparing VMware NSX to OpenStack, VMware NSX is simpler to implement.

I rate the initial setup of VMware NSX a six out of ten.

The price of VMware NSX is optimal. Additionally, the price of the solution can be negotiated with the vendor. Many areas of the solution can impact the cost, such as features, time for onboarding, and support needed.

We evaluated other options before choosing VMware NSX.

I rate VMware NSX ten out of ten.

I use VMware NSX for virtualizing networks for VMware virtual machines.

VMware NSX improved my organization because it's more flexible than network hardware and provides many solutions, such as firewalls and load balancers.

The most valuable feature of VMware NSX is the high bandwidth.

A room for improvement in VMware NSX is that it has some security vulnerabilities, which means my company has to apply the patches every once in a while.

I have two years of experience with VMware NSX, and I've worked with the solution in the last twelve months.

VMware NSX is a stable solution.

VMware NSX is a scalable solution.

I have no experience contacting VMware NSX technical support.

I didn't use a previous solution before I used VMware NSX.

My company went with VMware NSX because the infrastructure within the company is VMware.

The initial setup for VMware NSX is not that complex. It's in the middle, so I'd rate it as five out of ten.

I'm trying to remember how long the deployment of the solution took, but it didn't take up a lot of time.

A third party helped my company with VMware NSX implementation.

I have experience with VMware NSX.

I'm using the latest version of the solution.

Sometimes, VMware NSX requires maintenance. The third-party was responsible for the first time, and then the vendor took over the subsequent maintenance activities.

VMware NSX has about three hundred users in the company.

I don't know if there's any plan to increase usage for the solution.

My rating for VMware NSX is nine out of ten.

We use this solution for network virtualization alongside Nutanix and for the firewall blueprint. I'm an IT manager. 

This product is like the layer between traditional networking and virtualization. It gives you the flexibility to deploy and have network virtualization on different types of firewalls. We implemented this solution when we moved to the private cloud. 

The setup of the solution could be simplified.

I've been using this solution for two years. 

We haven't had any issues with stability. 

The solution is scalable, but we haven't tested that yet. We have three network engineers using the product. We don't plan to increase usage in the near future. 

The response time of the technical support team could improve. We also sometimes had the feeling that they didn't properly understand the issue.

Positive

The initial setup is not that straightforward. We used a consultant and even then deployment took a full week. It wasn't easy. 

This is a good solution if it fits your requirements. You can achieve a lot if it suits your needs. I rate this solution eight out of 10. 

NSX is a virtual network, and now is the right time for it. Technology-wise, it's actually an advancement in comparison with other solutions. We've been studying it, and so far, so good. NSX is the superior product when it comes to software for virtualized networks.

The non-enterprise version of the solution should be improved.

I want to see the solution expand to more than just the network, for example, perhaps it could provide some VLAN technologies.

I have been distributing this solution for over six years.

I believe the product is very stable.

The product is very scalable. I don't think NSX would have any problems with growth if a company wanted to expand their network and business. One person is enough to manage this solution.

Here in the Philippines, we need more technical support. I don't think they have good support here. There aren't any experts on NSX, only the distributor and reseller, so we have to really invest in training for us to able to understand the product.

Our team is already trained, so the setup is straightforward.

The licensing is renewed every three years. The cost for implementation and renovation are a huge portion of that price.

I think they need to market the solution more so that it can be accessible to more customers, because few are very familiar with it. It's hard to market it because we are provided with less marketing information about it, but in order to grow the product, it has to be properly marketed.

If you are looking for new technology of the future, NSX is one of them, and it will cost you less in power consumption since it's a virtual network as opposed to a pure physical network, which consumes more energy. That's a main advantage, that the operating expense will lessen while at the same time, the technology is great and is a secure network. When you're talking about virtual networks, I think NSX is one of the greatest products and will soon be the leader in the market.

I would rate this solution as a seven out of ten.
