vRealize Operations node types

vRealize Operations contains a common node architecture. Every vRealize Operations cluster consists of a master node, an optional replica node for HA, optional data nodes, and optional remote collector nodes.

When you install vRealize Operations , you use a vRealize Operations vApp deployment to create roleless nodes. After the nodes are created, you can configure them according to their role. You can create roleless nodes all at once or as needed. A common as-needed practice might be to add nodes to scale out vRealize Operations to monitor an environment as the environment grows larger.

Here is a low-level overview of the different node types, the component roles they can have, and the communication ports they use:

Although deployment will be discussed in detail in later chapters, from a design perspective it is important to understand the different roles, and what deployment model best fits your own environment.
