Enhanced security and streamlined management drive efficient connectivity

Open source is a standard solution where you take a gray box or white box and put the software from your end. You can do programming with Ansible and make the network work in the software-defined mode, providing automation and management capabilities. I am currently working with VMware. It integrates easily with everything and can work with any system. When discussing micro-segmentation, it enhances security, providing more secure data in your data center while allowing for extra layers of security outside your data center. If you have an ACI, there is communication between locations, keeping your data secure in your data center and throughout the path it takes, such as to SD-WAN or the cloud. I work with cloud solutions including AWS, Azure, GCP, and private cloud. My overall rating for VMware NSX is 8.5 out of 10.

Quotes from Members

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

Pros

"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."

"A great feature is the memory utilization graph."

"The most valuable features are ease of use and user interface."

"VMware NSX's overlay network is its most valuable feature, as it aligns with any network philosophy and allows for efficient addressing mechanisms. Additionally, the ability to extend the on-premise network into the provider space is beneficial. There are many features provided."

"It is easy to implement it."

"They have a lot of support and specialists who can meet with the customer."

"The most valuable feature of VMware NSX is the load balancing and routing of firewall rules. Many of the features are beneficial."

"It gives more security and micro-segmentation. It helps to set network configurations in an easy way."

"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."

"I have found VMware NSX to be easy to use."

More VMware NSX pros

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."

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

"In the next release, they should enhance the visual interface. With NSX-T, it's difficult to communicate between the public cloud and the container."

"We would like tenant segmentation available in future releases."

"We have been satisfied with the technical support. They were able to solve our problems. However, they could be faster."

"It might be nice to have more AI in the future."

"Lacks integration with other solutions."

"The solution is complex but for the key user, it's not really complex. You just need to learn the standards and mechanics for your specific product."

"It's not feature-rich."

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."

"I would rate the pricing of VMware NSX as seven out of ten"

"The price of VMware NSX is very good compared to other solutions."

"I was not involved in the purchase of the solution but I hear it is on the expensive side."

"There is a license required for this solution and there is also a support license available. The price of the solution could be better."

"VMware NSX isn't cheap."

"The subscription is on a yearly basis."

"I'm unable to give information on the pricing or licensing cost of VMware NSX because I've never been someone who looks into the economic part of any security or virtualization solutions. That's handled by an entirely different team, and I don't even have the slightest idea about the costs associated with the solution, though I've heard pricing for VMware NSX is on the higher side."

"All the institutions have to pay monthly for the services in the cloud. They have to pay $30,000 every month for this service every three years."
