Easy to set up with good documentation and helpful support
I'm using it for a customer The packet flow switch is the most valuable aspect of the solution.  It's an easy product to set up. We can scale the solution if we need to. It's stable.  The documentation is well-written and quite useful. It's compatible with other products.  Under the pocket flow…

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

"This solution has saved us hours (three to four) per problem when troubleshooting."
"Because we are doing proactive monitoring instead of reactive, the end users don't even see that there is something wrong."
"The most valuable feature is utilization."
"It's an easy product to set up."
"It helps us to assist our customers to isolate problems. If it is us who is having the problem, then we can use it to streamline the process."
"The technical support is really good. They will go above and beyond, if you are running into a problem. You can go to a sales engineer, who will engage technical support to help you out."
"The packet flow switch is the most valuable aspect of the solution."
"The product is stable. I have never had any issue where we have lost an InfiniStream, or visibility from that particular InfiniStream, throughout the bank."
"Previously, we had no idea how the dataflow worked. We knew how all the applications and servers worked, but we never knew how the dataflow was happening."
"It provides deep visibility into what is happening with traffic and helps us manage our network."
"The benefits are it gives us insight into our network, which we can't get anywhere else."
"Without that, you're going to introduce additional latencies and problems into your environment that you don't want."
"As a troubleshooting tool, it's a level-3 troubleshooting-skills tool and it's very easy to use and very easy to find the information that you need."
"With this product, we can precisely identify communication patterns between virtual machines within our data center, whether it's east-east or east-west communication."
"One of the most valuable features is the ability to look at the traffic flows, to look at NetFlow data."
"We have seen ROI by using it, as we used to use a few tools combined to get to what we're getting by using this solution now, so we don't have to pay as much support and we don't have to buy three or four tools to do what we need done."
 

Cons

"The solution is not great, but it is not bad."
"The scalability has some limitations and quirks to it. I would like to be able to upgrade rather than replace the whole thing."
"The monitoring and reporting tool needs improvement. Users want more information, such as the level of detail when doing a packet analysis. They want more detail to be able to isolate down to a specific point."
"The technology goes end-of-life on us every year, which is why I am looking forward to vSTREAM."
"Sometimes, we can't access it."
"I'd like them to make the product more user-friendly."
"Only problems that we have had are fiber issues going into the TAPs or vSTREAMs, which are usually local site issues."
"There is a timeout feature that we have been asking for awhile."
"I would like to see more interoperability on the firewall and low balancer sides."
"There's enough information there, especially in the visualizations, but I would love to see this in a kiosk mode, where I could have a dashboard for interested stakeholders to see and appreciate what's going on. Then, moving on to a more practical level for our Help Desk, our operations team could benefit by seeing, in real-time, a visual view of the network."
"After Broadcom acquired VMware, I would rate their support at five or less in many cases. It's difficult to find necessary documentation, open tickets, and get support."
"Support could be much better."
"The pricing is steep."
"The only real improvement they can make is to add more third-party vendors into the environment, mostly switch manufacturers, because it's really limited to Cisco equipment and there are a lot of companies out there other than Cisco."
"It's pretty much user-friendly, but it could always be friendlier."
"Technical support has been responsive. The response has always been immediate. Whether or not they've fixed it immediately is a different story."
 

Pricing and Cost Advice

"To capture more with the solution that we bought, you have to buy another InfiniStreamNG, and there are only four ports in the back."
"The price is a little high."
"I would like it to be more scalable with less spend."
"The scalability is good, but it comes at a cost. E.g., if you need 100 InfiniStream because you are sending gigs or terabytes of data to one InfiniStream, then you will have to purchase another InfiniStream, which are not cheap."
"This product could be cheaper."
"It can be scalable. It just costs too much. With a company as big as ours, it gets too expensive to accommodate every single site."
"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 has brought more money into our company."
"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."
"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."
"I rate vRealize Network Insight's pricing a seven point five out of ten."
"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."
"It's an expensive product because we have a lot of nodes."
