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

"Sometimes it took a month to troubleshoot something that we can now do within days."
"The generation of KPI-like information that feeds to the nGeniusONE (management) server is the most valuable feature."
"One of the valuable features is the packet decoding."
"vSTREAM gives us better visibility and reporting about our network infrastructure, allowing for cost-optimization."
"I would recommend the product."
"The most valuable feature is the profiling of the applications for micro-segmentation... It has made the migration to NSX much easier. Most of the sys admins within the smaller silos, they have no idea what ports are needed to run their stuff at all. I am pretty sure the micro-segmentation would never, ever have occurred without it."
"The most valuable feature is being able to easily see the path that the VM traffic is taking, what ports are in use."
"If you are going to implement NSX, it's a great tool."
"To some degree, it has increased performance, helped to more easily manage networks, and provided visibility."
"It's very user-friendly in the sense that the querying is just regular language like you and I speak or write. You don't need to know any SQL-query type of language to be able to get what you want out of it."
"If we can get it to provide those firewall rules it will literally save hundreds of man-hours, if not thousands of man-hours."
"We are better able to understand our needs for future growth and budgeting purposes."
 

Cons

"Room for improvement exists in filtering in the packet decode."
"The stability is okay, but sometimes we see that the memory on the server is not 100 percent correct and we need to stop and start the software to have it reallocated again."
"I would say that this is not a scalable solution."
"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."
"When we talk about those micro-segmentation rules, there's an Export function. It is very macro-segmentation oriented instead."
"We're still going through the learning pains so we haven't quite got out of it most of what we're looking for, yet."
"There is room for improvement as not all cases are getting resolved, and we often do not get L3 support directly, having to go through L1 and L2, resulting in delays that usually are a headache for us."
"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."
"vRNI needs more remediation where it hooks into NSX."
"The IT infrastructure industry is expected to evolve towards a hybrid cloud model in the next five to ten years. In this model, most of the customer's resources reside on-premise within a private cloud setup, such as VMware. Another segment operates within public cloud environments like Azure and AWS, and a portion remains in traditional data centers. There should be seamless interoperability between public and private clouds. AWS and VMware need to work together to make it possible. Whether users interact with on-premise infrastructure or configure resources in the public cloud, the user experience must be seamless."
"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."
"The pricing is steep."
 

Pricing and Cost Advice

"Licensing is quite expensive."
"I rate vRealize Network Insight's pricing a seven point five out of ten."
"They should include the product in NSX because it's important to have it for deployment."
"vRealize Network Insight is expensive."
"Cost always has room for improvement, you could always make it cheaper. But I think it's a good value for what you pay for it."
"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."
"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."
"We have spent less time investigating network flows, so it is absolutely cost-effective."
"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."
