VMware NSX Room for Improvement

Traffic flow introspection topology visibility is definitely needed because at the moment, NSX-T lacks in this area. A hardware scan of the ESXi host for possible incompatibilities should be added to NSX-T/vSphere, as it would allow us to know in advance, for example, if a pNIC is not compatible with a version of vSphere before moving forward with an NSX-T deployment. It needs a better, integrated migration tool. Something like RestNSX with more elaborate capabilities from a troubleshooting perspective and pre-migration perspective would be an improvement.

* 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.

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. View full review »

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 discouraging. If you compare other certifications especially from the cloud providers, you can get trained from your choice of training providers and not very expensive or learn on your own at your pace, prepare for exams and pass and your certificate will be issued. In contrast, you have to register under VMware to get training done at minimum of $3000 before your certificate is issued to you. The training costs a minimum of $3,000, which is expensive and should be reduced. View full review »

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. View full review »

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.

There are always issues integrating with Cisco. Switching is always a big problem for us because our switch is not supported. If the integration was more open, then it would be good. View full review »
