New Release: The Gorilla Guide to…® Network Visibility with VMware vRealize Network Insight, Express Edition!

Maybe your database runs on an in-house corporate server, but communicates 3,000 times per hour with a customer-facing application that runs on a dozen remote cloud services in different locations. If you’re asked to double the capacity, can you predict the impacts on network use and response time? Now suppose management decides to move the database servers into the cloud and asks you to predict the impact?

System administrators are used to generating a diagram for flows through a single router, or for a single network. It’s a whole new level of complexity to manage huge, hybrid, highly distributed environments. Network Visibility with VMware vRealize Network Insight describes the many factors that go into modern network administration, and the machine learning-based solutions offered by VMware vRealize Network Insight.

vRealize Network Insight doesn’t just trace multiple systems on a wide range of devices from different vendors and cloud services (including, of course, VMware installations). It knows what traffic belongs to each application. It looks at patterns, such as which VMs communicate with each other most often, to find the boundaries around the application. It’s even smart enough to figure out what services are the back-end (such as your database) and set up their firewalls automatically so only authorized applications can communicate with them. And it can divide the services into multiple tiers, protecting each with customized firewall settings.

Often, the key to such insight lies in millions of tiny pieces of metadata, such as vCenter or AWS tags and configuration information. vRealize Network Insight combines knowledge of all these things. It can determine specialized functions such as firewalls and load balancers, and understands Kubernetes concepts and categories. Figure 1 shows how you can view dependencies between nodes and applications.

There are many more possibilities for filtering and searching, which support both routine investigations of performance bumps and alerts for potential problems. Network Visibility with VMware vRealize Network Insight shows the newest features of this tool, along with how it supports common tasks such as cloud migration.
