The solution is used for network virtualization. Normally, in my cases, I was billing it for the government clouds, for NIC, the National Informatics Computer of India. For them, I was making a cloud where a different government, a smaller government entity, wanted to buy a cloud from the government clouds.

886,468 professionals have used our research since 2012.
What do I think about the stability of the solution?
The solution is stable and perfectly fine. There are no bugs or glitches. It doesn't crash or freeze.
What do I think about the scalability of the solution?
The solution can scale well.
We had a user base of around 1200 people.
How are customer service and support?
I dealt with tech support during pre-deployment, and they were fine. They were helpful when we were dealing with staging cases. I wasn't an active part of the actual deployment and can't speak of how helpful they were in that part of the process.
How was the initial setup?
I was the previous architect for the NSX, not the implementer.
My understanding is the setup process is quite straightforward.
Our deployment was quite big. Including the staging and all the stuff, we were able to deploy in a four-month timeframe. That is not only NSX, that is the complete deployment of the cloud. We had a few issues here and there, however, overall, it was fine.
It's easy to maintain for the most part. The orchestration layer for it was a bit hectic work for us. That needed a dedicated VMware team. Apart from that, everything was quite smooth for NSX or vSphere, et cetera, and it is quite simple to manage it.
What's my experience with pricing, setup cost, and licensing?
The finance team handles the licensing agreements. I can't speak to the exact cost.
What other advice do I have?
When going for multiple OEM solutions, like Juniper, Cisco, HPE, et cetera, NSX will be quite useful. Don't go for the ACSIs and all Juniper proprietary options since future upgrades will be a bit tough if something needs to be added. Therefore, if it is a multiple OEM architecture, go for NSX, it'll be more helpful.
I'd rate the solution eight out of ten.
Which deployment model are you using for this solution?
On-premises

Useful load balancing, feature rich, and priced well
Pros and Cons
- "The most valuable feature of VMware NSX is the load balancing and routing of firewall rules. Many of the features are beneficial."
- "The most valuable feature of VMware NSX is the load balancing and routing of firewall rules, and many of the features are beneficial."
- "The support from VMware NSX could improve."
- "The support from VMware NSX could improve."
What is most valuable?
The most valuable feature of VMware NSX is the load balancing and routing of firewall rules. Many of the features are beneficial.
For how long have I used the solution?
I have been using VMware NSX for approximately four years.
What do I think about the stability of the solution?
VMware NSX can be stable. However, before you start, you need a very thorough sturdy design. Once this is complete you can go on building your VMware NSX in your environment.
I went to VMware to look at their best practice designs, but they didn't apply to our environment. I had to take some parts of different designs and build my own that was exactly what was right for us.
Get the designs first, study them very thoroughly and after that, you can implement what will work for you.
What do I think about the scalability of the solution?
The scalability of VMware NSX is very good. However, you have to take into consideration that you have to study their documentation.
The amount of users or devices VMware NSX can handle depends on the resource that you allocate to the Edges and to the management cluster. They are small, medium, and large. A large allocation can handle thousands of virtual machines. We mostly deploy medium to large-scale systems.
How are customer service and support?
The support from VMware NSX could improve. We are a large company and when we have an issue we do not need to waste everyone's time with level one and two support. I try and explain to them I need level three support but they say they have to follow protocol and pass me through the different levels.
Which solution did I use previously and why did I switch?
I have used previously Cisco 1000V. It was much more expensive than VMware NSX. We cannot compare them because the Cisco 1000V is obsolete and I don't know if they have a newer version or something similar. They are not the same technology, Cisco 1000V is from 2015, and NSX-T is from 2021. There is a big difference between time and technology.
How was the initial setup?
If you have experience with the setup of VMware NSX it is simple, but if you do not it could be difficult. I would advise new users to contact professional support from VMware.
What's my experience with pricing, setup cost, and licensing?
The price of VMware NSX is reasonable.
What other advice do I have?
I rate VMware NSX a nine out of ten.
Which deployment model are you using for this solution?
On-premises

Feature rich, distributing routing useful, but expensive
Pros and Cons
- "This is a good firewall and overall it is rich in features."
- "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."
- "There are sometimes mismatch in the control, the details and what you actually see on the transport note."
- "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."
What is our primary use case?
Have used this solution to implement PAS (PCF) and have also used it for Native Datacenter networking as part of DC refresh.
How has it helped my organization?
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.
What is most valuable?
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.
What needs improvement?
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)
For how long have I used the solution?
I have been using the solution for approximately five years.
What do I think about the stability of the solution?
The stability is good and is getter better after each new release.
What do I think about the scalability of the solution?
The solution is scalable. In the 2.4 version, the controller got merged to create the cluster manager, it now is even better.
How are customer service and technical support?
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
Which solution did I use previously and why did I switch?
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.
How was the initial setup?
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.
What's my experience with pricing, setup cost, and licensing?
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.
Which other solutions did I evaluate?
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.
What other advice do I have?
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.
Which deployment model are you using for this solution?
On-premises

General Manager at Oplee
Has a straightforward setup process and enables efficient network management
Pros and Cons
- "The product has valuable features for security and network extension."
- "The network-extending capabilities for the physical environment need improvement."
What is our primary use case?
We use the product for disaster recovery purposes. It helps us expand the network and security for workloads running inside the environment. In the cloud, specifically with Azure VMware Solution or AWS, VMware NSX provides protection-related capabilities.
How has it helped my organization?
Regarding network management, it enables the ease of creating a network configuration for any application.
What is most valuable?
The product has valuable features for security and network extension. We can secure customer environments by effectively managing and securing traffic and facilitating seamless network extension. We can address challenges related to workload migration, where we often need to relocate workloads between environments due to changes in licensing or applications. The DFW, i.e., Distributed Firewall, is the most beneficial feature for network security and micro-segmentation.
What needs improvement?
The network-extending capabilities for the physical environment need improvement. Instead of virtualization, the ability to add physical servers to the network could be enhanced.
For how long have I used the solution?
We have been using VMware NSX since 2018. We have worked with different versions depending on the customer's requirements. We are working with the latest version as well.
What do I think about the stability of the solution?
It is a stable platform.
What do I think about the scalability of the solution?
We have medium to enterprise-level customers for VMware NSX. Regarding scalability, we can add new nodes or servers to the cluster. It automatically extends in a horizontal scale-out approach when the nodes are added.
I rate the scalability a ten out of ten.
How are customer service and support?
We open a case and await the engineer's reply on escalation. It is a process similar to that of other vendors.
How would you rate customer service and support?
Neutral
How was the initial setup?
The initial setup is straightforward. The implementation time ranges from days to weeks, depending on the business use cases per customer requirements. It involves the assessment of design, deploying, and verifying the same. I rate the process an eight out of ten.
What's my experience with pricing, setup cost, and licensing?
The product pricing ranges from medium to expensive. I rate the pricing a seven out of ten.
What other advice do I have?
VMware NSX has played a significant role in supporting your organization's efforts in automated network provisioning and creating multi-tenant networks, especially when integrated with vRealize Automation or other automation tools. We were able to create an automated orchestrated workload and manage IP assignments.
I rate the product a ten out of ten.

A highly stable solution that provides several features like VPN, load balancers, DFW, and gateway firewall
Pros and Cons
- "The most valuable feature of VMware NSX is the DFW (distributed firewall)"
- "Since most people are very much used to physical networking, they find it difficult to use VMware NSX in the initial stage."
What is our primary use case?
I was part of the NSX troubleshooting team from VMware, where we worked with different customers to troubleshoot their NSX operational issues. Also, I was part of the design and deployment team. We do PSO projects and migration for customers.
What is most valuable?
The most valuable feature of VMware NSX is the DFW (distributed firewall). The distributed firewall is much better and more powerful than the physical firewall because it's applied at the beginning level.
The software-defined version of VMware NSX contains all the security features like IPS and IDS. In the physical space, you have to get separate IDS, security, or load balancer products. VMware NSX provides several features like VPN, load balancers, DFW, and gateway firewall.
What needs improvement?
Since most people are very much used to physical networking, they find it difficult to use VMware NSX in the initial stage.
For how long have I used the solution?
I have been using VMware NSX for the past six years.
What do I think about the stability of the solution?
The solution's stability is very good compared to its older versions. It is advisable not to go in a production environment with the latest version because it might sometimes have new features that can break.
I rate VMware NSX a nine out of ten for stability.
What do I think about the scalability of the solution?
We can easily scale the solution with the current product version if we have more users.
I rate VMware NSX a nine out of ten for scalability
How was the initial setup?
The solution's implementation is easy.
What about the implementation team?
The initial phase of deployment involves deploying three NSX Managers. Then, you have to plan to do a lot of things like configurations and routing. If you have everything ready for configuration, you should be able to complete the VMware NSX installation in a month.
In the case of daily deployment, it depends on how much we are deploying and how many configurations we are doing. Two weeks should be more than sufficient to complete the configurations if we do it daily.
What's my experience with pricing, setup cost, and licensing?
VMware NSX is a cheaper product compared to its competitor, Cisco.
What other advice do I have?
Since most people are very much used to physical networking, they find it difficult to use VMware NSX in the initial stage. However, once you start using it, you'll be very much fond of the particular product. VMware NSX is very easy to manage.
You can deploy the solution on the cloud or on-prem, depending on the customer's requirement.
When changing from the physical to the virtual space, you have to plan the routing part. You'll have a hardening of networks in the physical space. However, when you bring it to NSX, everything is at the hypervisor level in the virtual space. That's one thing you will have to plan because a few critical applications might require a VLAN-backed network.
They have a restriction that they can't move it to the overlay networks and must remain in the physical VLAN. We have to plan properly for migrations because improper planning can break the current network or operations.
It would be good if users use all the features in the solution to have everything in one place. Users can access the web UI to manage security, load balancer, and VPN protection.
Overall, I rate VMware NSX an eight out of ten.
