Provides a memory utilization graph and shows disk space and uplink utilization but could include smart navigation in next release
The solution is deployed on-premises. There are more than 20 people who use this solution in my organization. They're infrastructure engineers, network engineers, and information security engineers A great feature is the memory utilization graph. It shows utilization, disk space utilization,…

Has improved network visibility and security through micro-segmentation and SDN capabilities
This feature gives us flexibility and allows us to manage everything under one pane. We can see everything on one console, including network operations and behavior. Monitoring and security are among the best features for VMware NSX. For micro-segmentation, it's integrated with our endpoint security. If there are any issues with servers or VMs, it notifies us so we can isolate the servers and investigate. It provides distributed security features such as firewall and intrusion, IDS, IPS. The security level with IPS and IDS in VMware NSX is excellent. It also provides logical switching and routing which gives an extra layer for Layer 2 and Layer 3 switching requirements. The solution provides flexibility, automation, and self-service capabilities, resulting in cost savings as extensive expertise isn't required. Once automation and self-service are implemented, many tasks can be completed automatically. Load balancing is another excellent feature. Multiple servers can run on load balancing features, which is particularly useful since we have many application servers running. Sharing loads between servers provides the best performance.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"We have a good relationship with NETSCOUT, and it's reflected in the communication and the service that we see from them."
"A great feature is the memory utilization graph."
"The feature that I have found the most useful is the decode of packets. It gives us a variety of information that helps us in figuring out what to look at. The networks are getting really complex, and without the information that we get from Iris Session Analyzer, we couldn't do our job. Its graphical user interface is also very easy to use and intuitive."
"Technically, VMware NSX is more advanced technology-wise when compared to others. We have been studying it and so far, so good. We know that the NSX product is superior when it comes to software virtualized networks. </p> <p>If you are looking to work with new and future technologies, then NSX is one of the best options. It costs less for power consumption since it will be a virtual network and not a pure physical network that consumes more energy."
"The solution is very good at micro-segmentation."
"To be able to do the DR and SRM migrations from datacenter to datacenter, we're able to do them with SRM with VXLAN, with the NSX product."
"From a security standpoint, the customer was able to better secure critical workloads while routing L2/L3 worked normally, giving them more confidence that they would be ready for any potential security incident mitigation or outage (DR)."
"Has a great firewall."
"It is a stable solution...The solution's initial setup process was easy."
"It is helping me get an entire blueprint done of the source and the target, I was able to make it into a catalog and can set up anything on the cloud quickly."
"Though I haven't been working a lot on VMware NSX, it's good to have. What I like the most about it is that its console is good, and it doesn't take a lot of effort in terms of doing my daily tasks on it or what it's meant for. VMware NSX is still a preferred product in the market."
 

Cons

"Sometimes the network analyzer will show that a server is down when it's actually working."
"They can increase flexibility in the search engine. Basically, I go with the information I have at the time. If I could just type in the parameter that I want to search for and its value, it might be easier than having to do the groundwork upfront before I can get my traces."
"They need to enhance their technical support. There is no comparison between VMware technical support and Cisco's technical support."
"The solution is quite complex."
"Lacks integration with other solutions."
"The price is expensive and it could attract more purchasers in smaller organisations if it was reduced."
"Since most people are very much used to physical networking, they find it difficult to use VMware NSX in the initial stage."
"The solution could benefit from improvements in its pricing and scalability."
"I have concerns on the stability of VMware NSX, because it breaks multiple times in customer environments, especially when you scale it across a big data center."
"If you compare NSX to a similar solution you might find it to be a bit more complex."
 

Pricing and Cost Advice

"I don't know what the cost to buy the solution was, but I doubt if it's a significant part of the budget as far as the maintenance and support are concerned."
"We are using a perpetual license to use the solution and we have support."
"VMware NSX is a cheaper product compared to its competitor, Cisco."
"If five is a good price and one is a high price, I would rate the price a one out of five."
"The price of VMware NSX is very good compared to other solutions."
"Pricing and licensing could be improved as we are a government entity. Lower pricing could always help."
"VMware has a subscription and perpetual license. In the New Year, they're changing many things about the licensing model. Previously, NSX was licensed according to the number of sockets inside the appliance, so we bought VMware licenses based on that. However, that may have changed this year. We are still contacting the vendors to understand the new licensing strategy."
"The tool's pricing is reasonable."
"The subscription is on a yearly basis."
