What is most valuable?

The easy integration and management are the two most valuable features. In regards to Layer 4 and 7 load balancing with a solution, for us, it's about the continuity. We look for different ways to… more »

What needs improvement?

Which solution did I use previously and why did I switch?

We based our decision to switch solutions on an analysis we did. We based this analysis on what we are missing and what the impact is of not having it.

What other advice do I have?

This solution has helped our clients save CapEx. The agility and speed of the implementation offer CapEx savings. It does and doesn't prolong software refresh. It does because there is better… more »

Which other solutions did I evaluate?

We look at different vendors for our customers. It depends on the compliance and regulations that are in the systems for every single company's requirements. Every company will have specific needs for… more »

What is most valuable?

The most valuable features would be the easy management and the possibility of using our existing vSphere environment so that we don't need to purchase a new hardware… more »

How has it helped my organization?

The reusability of the objects for the switches has improved our client's organization. For example, if I do some sort of vMotion, there is no need to recreate the portal… more »

What needs improvement?

I would like them to make integration with other vendors easier.

What's my experience with pricing, setup cost, and licensing?

It has saved us CapEx. They should adjust the license for NSX so that we can invest in the infrastructure or purchasing of new hardware. This solution is reasonably priced… more »

Which solution did I use previously and why did I switch?

I'm involved in the decision making. My boss would say that it's time to advance the customer so we'll look into a solution. We were already a VMware-based customer so our… more »

What other advice do I have?

I would rate this solution an eight because of its ease of deployment. I'm a partner so this is what I mostly care about. Also because of the ease of scalability. If… more »

Which other solutions did I evaluate?

Our customers usually compare NSX to Cisco ACI. The main issue is the underlying network that VMware does not provide visibility to. They chose NSX because they were… more »

What is most valuable?

The microsegmentation is great, and the security team thinks it is great.

How has it helped my organization?

It makes our life easier as far as PCI and auditing are concerned. We have been audited over the last few years, which has brought up concerns and issues. The easiest resolution for this was to put… more »

What needs improvement?

The solution is quite complex. You need to keep your thinking cap on and know what you are doing: Go to the training and listen to the solution architects when they come in because they have a lot of… more »

Which solution did I use previously and why did I switch?

We didn't have anything before. The solution was highlighted by audits, which is why we decided to put it in.

What other advice do I have?

If a colleague was to ask me if it was a good idea to go ahead and put it this solution in, I would say, "Straightaway." I wouldn't have any doubts.

Which other solutions did I evaluate?

We deal directly with Dell EMC and VMware via Dell. This solution was the only thing on our radar. We didn't even look at anything else.

What is most valuable?

Automation, because we're constantly onboarding massive customers. We have our own management system, which integrates nicely with NSX. Therefore, we've built an automation layer so we can deploy and completely secure new customers in a… more »

How has it helped my organization?

The microsegmentation allows me to sleep at night. My job is reducing risk, plugging security holes, and working with the automated layer security. Even if somebody spins up a new server, it has to have a tag in NSX. Therefore, all the… more »

What needs improvement?

I would like to have automating reporting built into common service management platforms, such as JIRA, Serviceaide, and ServiceNow.

Which solution did I use previously and why did I switch?

We jumped onboard with NSX right when it started. VMware worked with us when we had issues or made suggestions to the point that we were invited as a partner to 2016 VM World, because we contributed so heavily into NSX. It has been nice to… more »

What other advice do I have?

Get it in your environment as soon as possible. Network segmentation is hard. A lot of businesses still use the traditional three-tier system, because it has been proven, but it isn't particularly robust or secure. Realistically, it's a… more »

What is most valuable?

This is the most scalable product of its type. It is very good for automation and software-defined networking.

What needs improvement?

I would like to see improvements made to the certification process. As it is now, you have to do the training with VMware itself, and you have to spend a lot of money doing it, which is very… more »

What's my experience with pricing, setup cost, and licensing?

The licensing fees are expensive and we pay on a yearly basis. However, we were able to leverage some of the licenses that we had for an affiliated product, ESXi. There are no costs in addition to the… more »

Which solution did I use previously and why did I switch?

We did not use another network function virtualization product prior to this one.

What other advice do I have?

This is a good product and one that I recommend for anybody who does not want to change their existing infrastructure. The problem is that they have to compete with the likes of AWS and cloud… more »

Which other solutions did I evaluate?

We chose VMware NSX-T because it was the most scalable.

What is most valuable?

Any administrator with basic networking knowledge, in a couple of days, can be in full control of their networking without going through a networking engineer. The microsegmentation feature is the reason why everybody wants to implement NSX. It's just awesome. I was impressed by it when I saw it for… more »

How has it helped my organization?

After working for about 10 years as a consultant and always waiting for networking engineers to either attend meetings, then do the changes or be willing to do the changes that we need. NSX has improved the process.

What needs improvement?

We would like them to improve the deployment time. The management console also needs a bit of improvement.

What other advice do I have?

The solution is not complex. Though, you need to have some experience in networking, but just the basics that come when you work in the industry. However, if you've never worked with networking, start at the beginning, then NSX will come along easily. I recommend building your own lab and continue… more »

What is most valuable?

We like that we can split networks. Layers 4 and 7 are nice. We like that load balancing is easy for the person running it and certain features like the web bouncers F5. We like that the… more »

How has it helped my organization?

I use the cloud now but in the past, we were able to create very specific segments for each part of the company.

What needs improvement?

At the moment it hasn't helped us prolong our hardware refresh.

What's my experience with pricing, setup cost, and licensing?

It has helped us save CapEx but I'm not sure exactly how much.

Which solution did I use previously and why did I switch?

We were trying to save money and trying to use a more flexible solution so we decided to go with NSX as opposed to another hardware or solution.

What other advice do I have?

I rated this solution a nine because it's easy to use. It has a lot of capabilities, like microsegmentation, which is very good. If you're worried that NSX is too complex, I would tell you to take… more »

What is most valuable?

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.

What needs improvement?

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.

Which solution did I use previously and why did I switch?

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.

What other advice do I have?

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… more »

Which other solutions did I evaluate?

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

What is VMware NSX?

VMware NSX is the network virtualization platform for the Software-Defined Data Center (SDDC). By bringing the operational model of a virtual machine to your data center network, you can transform the economics of network and security operations. NSX lets you treat your physical network as a pool of transport capacity, with network and security services attached to VMs with a policy-driven approach.
