VMware NSX Reviews

Many of our customers are moving to these kinds of options in order to reduce the number of physical devices and to increase security. I'm an architect of enterprise business and we are an enterprise partner with VMware.

The solution is valuable in that it makes it very easy to protect virtual machines

The product is quite complex and that could be an area where improvements could be made. 

I've been using this solution for over a year. 

This solution is stable. 

The solution is scalable. I've implemented it in an organization with 2.000 servers and it's fine. That is my experience. I don't have experience with larger environments. 

We are directly linked to VMware so we haven't needed to contact the technical support. 

We did face some challenges with the initial setup. 

The cost of the solution is a little high, particularly given that most people will not use all the features of the product. If a customer does use all the options, it is a very cheap solution but that is unlikely. For a regular user looking for normal switching, the price feels high. If it's implemented properly you can reduce the cost.

This is a good product and I highly recommend it. 

I would rate this solution an eight out of 10. 

Primary use case is to implement network virtualization for L2/L3 traffic in customers environment and at a minimum implement baseline micro segmentation. each customer has a different business requirement depending on how their existing network is setup --what physical L3 devices are in place and how NSX will need to be configured to function properly.  Most customer using NSX V that we have worked with are running UCS servers or HP

with vsphere 6.7 /7  mid level transport node counts respectively etc.

It has allowed our customers to scale/extend their existing IP subnets and spin up new subnets on-demand for new app/web/DB tiers. Increasing overall VM-to-VM security and policy deployments. It has helped increase operational efficiency from a network management perspective. Many firms have multiple racks of equipment at different data centers that leveraging NSX definitely helps (extending the 'same' IP subnets to different racks in the same data center). For customers who use SRM, there are also great benefits (i.e., not having to manually re-IP DR-side VMs during a failover test).

• micro segmentation features
• VDS
• NSX Transport zone
• vxlan encapsulation
• edge services gateway 
• distributed logical router
• esxi Vtep

By utilizing NSX V solutions from VMware, customers have the tools needed to move their data regardless of the underlying physical network. They can do this in a way that enforces proper security policies and compliance regulations. Even with SDN solutions, customers must protect their business-critical data residing in their virtual infrastructure

NSX V has less security features than NSX T just so you are aware

• NSX Manager console: limit on number of NSX Controllers an architecture can have
• Support for ESXi, KVM, bare-metal servers, Kubernetes, OpenShift, AWS and Azure.
• Integrate NSX Controllers into NSX Manager as a single virtual appliance so controllers no longer need to be deployed independently.
• Directs to vCenter by registering Transport Nodes instead of registering NSX Manager inside of vCenter.
• Use a more modern overlay technology for encapsulation that performs better and is more flexible for the future over older, more traditional VXLAN overlay technology.

I have used it for 3+ years.

Stability factors stemmed from existing ESXi host setup/configuration/performance and compute capacity; did not identify any stability issues with VMware NSX solution itself.

No scalability issues encountered.

Customer Service:

Customer service is 10/10.

Technical Support:

Technical support is 10/10.

No previous solution in place.

Straightforward setup; best practices need to be adhered to.

Implemented in-house in PoC/prod; showed customer PoC demo, then implemented at customer site with positive results.

As a VMware Partner, our ROI is the same as our customers perhaps. NSX helps us leverage our existing infrastructure that is used for training/consulting purposes.

No other options evaluated. VMware is the leader in network virtualization.

Typically CCIE's are the ones tasked with implementing NSX due to their solid network background. Organizations for the most part do not have resources that know VMware as well as they know Cisco. The skills required to be well versed in deploying this technology is rare.

We use this solution to build our VMware platform.

The most valuable features are security and dynamic routing.

The routing functionality needs to be improved, as there are lots of bugs in the system.

I would like to see automation capabilities in the deployment process.

I have been using VMware NSX since 2016.

I think that there is room to improve from a stability standpoint. There are lots of bugs in this product.

VMware NSX is highly scalable.

The technical support team is good.

I would not say that the initial setup was straightforward. In terms of how easy it was to complete the deployment, I would rate the process a seven out of ten. 

My advice for anybody who is researching VMware NSX is to first have an understanding of network engineering.

I would rate this solution an eight out of ten.

We are a professional services company and we have been evaluating VMware NSX for our clients.

The most valuable features for us at this early stage are the interface and the integration with existing VMware solutions.

The Active Directory network integration and load balancer are good features.

Everybody needs a network to connect to, and VMware doesn't readily provide one. It is reliant on an existing network to connect to, which means that for me, it requires two different teams to manage the SDN.

We have been working with VMware NSX for a couple of months.

It seems like a stable product.

I have not checked on the scalability, although from what I have read, it seems like there might be some concerns. I will know more once I get the opportunity to test it.

At this point, we have a team of just three people who are using it.

We have not had any reason to call technical support at this stage.

Community support seems ok.

We are mainly a Cisco house, but we are trying to use VMware NSX as the next stage of our software-defined networking (SDN) expansion.

I'm not a VMware expert and as a network engineer, I find the setup to be quite complex.

I am currently in the process of comparing this solution to Cisco ACI.

My advice for anybody who is considering this product is to definitely start with a proof of concept. Be sure to understand your business requirements, networking, and security requirements as well.

I am currently evaluating different scenarios on scalability, integration with other products, and the underlay of the solution. While it may be a good product, I think that VMware should buy a network provider that offers the entire end-to-end networking solution.

I would rate this solution a five out of ten.

Our primary use case is moving from physical to VM infrastructure.

This solution has given us the ability to move from a physical to a virtual server estate with all of the expected VM benefits of decoupling servers from dedicated hardware.

The most valuable feature is the ability to create, develop, and deploy servers in minutes to hours, rather than days.

It could be cheaper!

I have been using VMware NSX for seven years.

We use it as a distributed firewall and for security purposes.

It has reduced the number of people on the network team along with the system engineer involved in the security process. So, it is valuable.

We can't go without NSX, so it's invaluable from this perspective.

Its flexibility and integration with other VMware solutions are NSX's most valuable features.

The microsegmentation feature is very useful.

We would to have a reverse proxy. This would add great value to the solution. 

We would also like better integration with the standards on the market. For example, with OSPF, their integration in NSX is very low. It's not a full OSPF integration. It is too thin from a protocol perspective.

The product need to be improved. It is too complex.

The stability used to be perfect. Now, it is okay.

From a distributed firewall perspective, it's a solid solution.

It is scalable by design, so it's perfect.

The technical support is good. We have encountered several problems with NSX, and every time, support has found the solution to resolve the issue. 

In our company, we were starting a hosting solution, so it was by design. We have worked with VMware products for a long time, so it was natural to buy NSX.

It was a complex setup.

We implemented it ourselves.

The solution is expensive.

We did not consider anyone else.

If someone is looking for security in a vSphere environment, I don't know of another solution in the market besides NSX.

We had to buy new hardware in order to introduce NSX into our data center.

We don't use load balancing with this solution.

We don't use vCloud Director.

• Deployment
• Planning and designing
• Troubleshooting sustain.

• Faster delivery of VMs
• Providing NAT
• Firewall rules
• Balance
• Connectivity between physical and virtual environments.

Visibility, because on our environment, it's impossible mapping end to end, and we don't have any tools that provide this integration.

• vRNI
• Improve integration with many third-party solutions, because only Palo Alto and Check Point, and VMware would be like improve this integration with other vendors.

We use this solution in our private clouds networking environment. We have some subsidiaries that we service and are trying to isolate each of them in this network.

It has helped us prolong our hardware research. We haven't had to change hardware in five years.

Security and cloud readiness are the most valuable features for us. We're interested in looking into microsegmentation. 

I would like to see some more add-ons on the security features. 

It's very stable and robust. We haven't had any issues with it. 

Scalability is a great feature. 

Their technical support is very good. They help us figure out solutions when we have problems. 

The initial setup was straightforward. 

We integrated in-house. 

I would rate this solution a nine because we maximize most of its features. We have many advantages with the cloud infrastructure. I would tell someone looking into this solution to go for it. At first, it may seem to be complex but using it will make it easier to manage jobs. Yes, its initial establishment can be complex but you will see its advantages later on.
