What is our primary use case?
It's not just on the networking side that we use it. We use vRealize products in our product data, in developing software, as a managed cloud provider. We use vRealize Network Insight as part of our product, which can later be used by the support team to check all the problems which are arising in the network itself. We use software-defined networking, SDN. That's one reason we are using it.
In terms of its performance, we are still in a beta version of our product itself. We are not using it greatly in production yet but we will be using it in two or three months, down the line. There are network flows that we need to know about, if there are any anomalies in the network itself - depending upon the network that our team has deployed. That's the reason we use the vRNI tool, to look into all these parameters.
We also use it for a few performance parameters, depending upon if there are any configuration issues in the network that we have deployed. vRNI has given us a few recommendations on how we can actually set up our firewalls.
How has it helped my organization?
It saves us on our SLA times because we are getting directly to the troubleshooting points. That is one of the main things that we are benefiting from. Whenever we have problems with our environment, we are able to solve them a bit sooner than we might otherwise have been able to. These benefits are directly connected to monetary benefits. It has helped to reduce time to value.
While increased performance depends upon what we are using in our networks, Network Insight is more towards how we actually see the entire network as a whole. Performance is mostly determined by what physical parts we are using in the network. While vRNI does not exactly increase the performance, we can better use the network we do have.
Finally, it provides deep visibility.
What is most valuable?
It has its own UI where you can actually see all the problems. It can directly list all the problems that we're having in the network. Not only that, but it also gives us recommendations on how we can troubleshoot issues. That helps us to go to the problem in the network and not look around at a hundred places to actually troubleshoot a single issue. That's one of the most common use cases we have, troubleshooting the problems in our network.
Whenever we say "valuable" with respect to the network, it's more towards the security. The firewall rule issues it shows us and the recommendations that we get from vRNI are the most valuable features because they are actually making our network more secure.
I also think it is intuitive and user-friendly. I've been using this product for a long time now. If you look at the UI, you see how user-friendly it is. It has a lot of features in it and it has a lot of options that you can go through. Everything that you actually need to know is covered in the product.
What needs improvement?
While it's not exactly a feature, what normally happens when we are trying to look at the VM flow portion is - although Network Insight does have options to integrate a few physical switches into it - we can't really get an end-to-end flow of the network. We might be using a few switches that are not supported by Network Insight. That is where they can improve, in the support for more physical switches and network devices.
For how long have I used the solution?
One to three years.
What do I think about the stability of the solution?
It is quite stable. We haven't had any downtime with it.
What do I think about the scalability of the solution?
We have not tried to scale it yet.
How was the initial setup?
The implementation is quite straightforward. We were able to go ahead and install it with the plans and recommendations that were provided.
We have also upgraded it. There are two proxy platform VMs when it comes to Network Insight. In the newer versions what I discovered is that you can directly install it through the UI, so it's a little automated. In the older versions, we had to do it from the CLI. So this is a new feature in it.
What other advice do I have?
I would recommend the product. I don't think there is any other product like this on the market right now.
I rate this product at seven out of ten because the product is great but there are still a few more improvements that can be made to it, as I said above. It could have more physical devices integrated and supported.
When selecting any type of vendor, our most important criteria is support.
