A user-friendly solution that is easy to install and improves visibility

I would like to see improvements made to the user guide. From my personal experience, it is helpful to see a list of steps describing what to do next in different situations. An example is what to do and what to back up in the case of certain types of failure. There are also cases where a customer can't understand specific features. Enhancements to the user guide would be helpful for this. More features for network fragmentation would be helpful.

Comprehensive management and detailed reports benefit operations while improvements are needed in support and maintenance

We have Tanzu and OpenShift. We have OpenShift, Canonical, and the Tanzu one. The Tanzu platform from VMware is a Kubernetes platform. We haven't completely installed Tanzu yet; we installed the vROps part. vRealize Network Insight is beneficial because you can control the East-West traffic. vRealize has a component called NSX, which has East-West traffic controlling and micro-segmentation, that is one of the best options, and we have the layer extension, layer 2 extension possible through NSX. If you have anything accountable in any business, even in a candy business, having proper accountability on what you are selling and buying will save a lot. If you don't know what you're selling and buying, you will end up with a loss. My team does not use the flow analytics feature; we have a security and network monitoring team, which is a different SOC team. I am using it as an administrator internally. We perform different tasks including costing analysis, capacity management, and many other things. vRealize Network Insight has a concern about the maintenance part, as it requires a person to monitor it completely. It's not something you install and your report will be generated automatically. You have to work on this properly to get the insights. vRealize Network Automation, vRealize Operations, and vRealize Network Insight are completely related to the network. I cannot say much about these network aspects because I am on the operations side, but overall, the vRealize suite is good for reporting perspective or any ISO-related documentation; this is very helpful. The product is called vRealize Operations Manager, and now it is referred to as Aria or vAria. I am now a Senior System Specialist. We use different metrics because we have multiple departments, and we can monitor utilization and comparisons with the previous year. On a scale of one to ten, I rate this solution a seven.

Quotes from Members

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

Pros

"vSTREAM gives us better visibility and reporting about our network infrastructure, allowing for cost-optimization."

"One of the valuable features is the packet decoding."

"We haven't had any complaints about the stability of the solution or heard of any issues. None of our clients have mentioned running into bugs or glitches. There haven't been crashes."

"It is user-friendly. It's pretty simple to deploy and to run. It gives you pretty easy-to-understand reports, very graphically intense, so you can visualize what's going on in your network."

"The most valuable feture is NetFlow to help us understand how VMs communicate with each other over ports that are known and ports that are also unknown to us. Our company is a security company, so it's very important for us to know exactly which VMs are doing what at all times."

"One of the most valuable features is the ability to look at the traffic flows, to look at NetFlow data."

"It provides deep visibility into what is happening with traffic and helps us manage our network."

"It gives the visibility that was either broken or there in pieces only. This solution provides a unified view of the whole system, back and forth. It has helped to reduce time to value, increase performance, more easily manage networks, and provide deep visibility."

"The graphical interface of this environment is so good with all the views, the graphics, and everything in them. It's really easy for me. It doesn't need an engineer to work on it. It's easy enough that anyone can get into the environment and look for issues or look at how communication is going on across the VMs. It's pretty much straightforward."

"compare-to-competition; I would recommend the product. I don't think there is any other product like this on the market right now."

Cons

"I would like for it to have a smaller footprint of the virtual appliance and better performance."

"I would like to see improvements made to the user guide."

"Room for improvement exists in filtering in the packet decode."

"When we talk about those micro-segmentation rules, there's an Export function. It is very macro-segmentation oriented instead. So if you choose an application, it will find the tiers within that application and say that it's communicating on, say, port 80 to a separate VLAN. There might be 200 machines in that other VLAN. You don't want to open port 80 at all of them. So we need a lot more granularity in those suggested firewall rules."

"Support could be much better."

"There are some random glitches in the Web UI, but they are usually pretty cosmetic in nature. I don't really seem to use any browser other than Chrome with it. I also get some weird errors from time to time on the hardware NetFlow Collectors, where it doesn't sync data."

"If it were more application-aware, more descriptive; if it were able to determine the application that is actually doing the communication, that would be easier. More application information: which user or account it's accessing, is it accessing this application, doing these calls, if it is accessing a script, what script is it accessing. Things like that would provide deeper analytics so I can track what's going on. It would not just be, "These people shouldn't be talking," but who is actually doing these calls."

"The only issue we have is that the solution does not always capture the host names."

"The only reason I would not give it a nine or a 10 is for cost reasons. It seems to be one of those things that really belongs as part of the product inherently and not as an add-on. That would be my only concern."

"Since Broadcom acquired VMware, it has been experiencing challenges. Many sales processes are not well defined."

"The UI, even though once you get to know it, it's easier, still it's hard to figure out by yourself. You have to go read, watch videos. It has a lot of data on it. So that is an issue."

Pricing and Cost Advice

"Licensing is quite expensive."

"They should include the product in NSX because it's important to have it for deployment."

"It's a little expensive, but for what you're getting out of the product, you often see the trade-off. It depends on the type of licensing you have. It might be a little too pricey for some."

"I rate vRealize Network Insight's pricing a seven point five out of ten."

"The solution has reduced the time that we spend on other products. For example, with NSX, we were able to quickly find things that we would normally spend days trying to figure out."

"It has brought more money into our company."

"The solution has helped us to reduce time, increase performance, reduce costs, and even easily manage networks. We are probably seeing 10 to 20 percent labor savings because we are able to be very specific and focused on what we want to do. It ends up saving the customer money and makes us be more efficient on our cost deliveries."

"It reduces costs. It takes something that may be challenging and makes it more usable and visual by being able to bring in tools, seeing what their impact is, such as microsegmentation and application rationalization, and seeing it quickly."

"We have spent less time investigating network flows, so it is absolutely cost-effective."
