VMware Technician Manager at VAS
Provides more security and micro-segmentation but needs to support more platforms
Pros and Cons
- "It gives more security and micro-segmentation. It helps to set network configurations in an easy way."
- "VMware NSX only supports some platforms like KVM."
What is our primary use case?
It's very useful for making network configurations and setting the network configurations in an easy way. The infrastructure team has all of the components under these controls, that is, the infrastructure and the network itself.
What is most valuable?
It gives more security and micro-segmentation. It helps to set network configurations in an easy way.
What needs improvement?
NSX-T supports more platforms, and VMware NSX only supports some platforms like KVM. I want to see support for Hyper-V and other hypervisors.
Their technical support could be faster as well.
For how long have I used the solution?
I've been dealing with this solution for around three years.
How are customer service and technical support?
I think that technical support should be faster.
How was the initial setup?
Sometimes, deployment can take around four weeks. For the design and deployment, it can take eight weeks. We need more days, at times, for migration or for deploying security.

Intuitive system, highly scalable, and reliable
Pros and Cons
- "I have found the system to be very intuitive, functional, and they have great technology."
- "In the future, the solution should be compliant with internet NIC."
What is our primary use case?
We use the solution mainly for micro-segmentation and to permit security on flat networks without a V-LAN.
What is most valuable?
I have found the system to be very intuitive, functional, and they have great technology.
What needs improvement?
One of the areas that we are struggling with is how do we perform the same security level as we had for an NSX solution for the legacy system. For example, if I have a switch, and I am connecting a legacy application on the legacy system that does not support the hyper vision or another feature, is possible to push the security topic to the switches to be compliant, or compliant with an NSX component, and to perform the same security level as we perform for hyper vision side. It would be beneficial for us if there was better integration with legacy systems.
In the future, the solution should be compliant with internet NIC. They could deploy this NIC into some switches, servers, or other product. It would be interesting to have this sort of NIC stamped by VMware, and we could push some security feature into it. It would be a very useful feature. I do understand VMware is virtual and not on a physical device path but this would be a good endeavour.
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 solution is completely stable.
What do I think about the scalability of the solution?
The solution is highly scalable. One of the biggest infrastructures we have deployed the solution in has approximately 70,000 people using the solution.
How was the initial setup?
The installation has been complex.
What about the implementation team?
This solution can be very complex to deploy. We have assembled complex deployments at a few huge network site. We work for several customers in the communication and industrial sectors that have complex environments.
What's my experience with pricing, setup cost, and licensing?
The price is based on the virtual desktop infrastructure(VDI) side and also is dependant on the size of the environment. The price is expensive and it could attract more purchasers in smaller organisations if it was reduced.
What other advice do I have?
I would definitely recommend this solution to others. I have deployed it in many different types of environments and it operates well.
I rate VMware NSX an eight out of ten.
Which deployment model are you using for this solution?

- "Over the last two years, they've enhanced a lot, especially in regard to integration with OpenStack."
- "They need to enhance their technical support."
What is our primary use case?
Our clients consist of enterprise companies.
What is most valuable?
From my experience, VMware on a private cloud is a good choice. They offer some great webinars and workshops to learn how to use the product better.
Over the last two years, they've enhanced a lot, especially in regard to integration with OpenStack.
It's great for building a virtualized environment. It features great motion mobility, its own logical distributor, router switches, load balance, firewall, etc.
For how long have I used the solution?
I have been using VMware NSX for four to five years.
What do I think about the stability of the solution?
Personally, I find VMware NSX to be very stable.
How are customer service and technical support?
They need to enhance their technical support. There is no comparison between VMware technical support and Cisco's technical support. It's one of the main criteria that everyone is looking for.
How was the initial setup?
The initial setup was straightforward. Deployment was very easy.
What's my experience with pricing, setup cost, and licensing?
VMware NSX is expensive and everything is licensed. We have to pay for each individual feature.
What other advice do I have?
Be sure to read over the documentation on their website. They announce a lot of webinars and workshops for the product. It's good marketing and you should attend them.
Overall, on a scale from one to ten, I would give this solution a rating of six.

Comprehensive graphical interface, overall functional, and great technical support
Pros and Cons
- "Some of the key features I find most valuable are the highly graphical user interface, virtualization of networks, and Microsoft application compatibility. It has all the functionality that we require."
- "One drawback is this solution requires a lot of other products in the VMware ecosystem to have a full end-to-end operation orchestration monitoring. You have to buy a lot of add-ons to fully utilize the functionality."
What is most valuable?
Some of the key features I find most valuable are the highly graphical user interface, virtualization of networks, and Microsoft application compatibility. It has all the functionality that we require.
What needs improvement?
One drawback is this solution requires a lot of other products in the VMware ecosystem to have a full end-to-end operation orchestration monitoring. You have to buy a lot of add-ons to fully utilize the functionality.
Some additional features in the next release could be for the solution to be more directed toward the end-to-end functions, from physical to virtual monitoring. It should also include streamlined troubleshooting of our operation.
For how long have I used the solution?
I have used the solution for approximately two years.
What do I think about the stability of the solution?
The solution has been stable.
What do I think about the scalability of the solution?
I have found the solution to be highly scalable.

Senior Cloud Consultant with 201-500 employees
Good security with improved scalability and allows for the creation of virtual access networks
Pros and Cons
- "One of the big improvements between the NSX-V and NSX-T is that in NSX-T you are no longer dependent on V-Center anymore."
- "Some configuration maximums are limiting to the user, especially when it comes to the deployment of very, very large environments."
What is our primary use case?
I work with two different companies with different large cloud environments.
This product is a software-defined network, and that allows you to create virtual access networks and managing security to allow for different workloads.
What is most valuable?
The solution offers a very good software-defined network that allows you to create virtual access networks. It's very helpful at allowing you to manage security to allow for different workloads.
One of the big improvements between the NSX-V and NSX-T is that in NSX-T you are no longer dependent on V-Center anymore. That was a huge improvement due to the fact that it allows you to take into account new cases, and have better scalability, among other improvements.
What needs improvement?
There is always room for improvement, in any solution.
In some cases, this product is very technical.
Some configuration maximums are limiting to the user, especially when it comes to the deployment of very, very large environments. There are limits to the number of firewall rules, security groups, et cetera. With the number of security groups, you can nest all these limits, however, somehow limiting the use cases may be restrictive for the free design of different use cases.
For how long have I used the solution?
I've been working with the solution for a while at this point. It's been at least a couple of years.
What do I think about the scalability of the solution?
The scalability capabilities have improved in NSX-T. It is much better than when the NSX-V version was out.
I work with two different clients, both of which are quite sizeable. They have thousands of machines and thousands of security groups.
Which solution did I use previously and why did I switch?
I didn't work with another solution per se, however, the previous triggered cloud tool that we had was by VMware. It was not really, at least at the very beginning, a tool for a software-defined network, however, there were some elements that allowed you to create customer networks practically on the fly. There were also some other network visualization techniques, which allowed you actually to encapsulate the traffic and to create networks on the fly. You had some security constructs, including tenents constructs, that you can find somehow in the VRA today. The tenant concept is also present in NSX.
What's my experience with pricing, setup cost, and licensing?
Our customers can use the solution for free, however, this comes with restrictions.
What other advice do I have?
We are consultants and integrators. We have a business relationship with VMware.
I am working with both NSX-V and NSX-T. The latest one is actually NSX-T.
On a scale from one to ten, I would rate it at an eight.
