Newwork And Collaboration Supervisor at Nafeza
Monitoring has improved bandwidth insights and application diagnosis but setup and costs still need work
They need room for improvement about the spare parts. There are shortages in Egypt in their stock. We tried to make RMA for specific parts, and it took a long time. Comparing this to a vendor like Cisco, who provides any component next business day, NETSCOUT nGeniusONE took a long time. This needs more improvement. I believe it is expensive. They need to reduce its budget a little bit. Comparing to other solutions, it is very expensive.

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.
