Oracle Cloud Infrastructure Cluster Placement Groups lets you create resources in close proximity to one another to support use cases where low network latency especially matters. By using Cluster Placement Groups, you can deploy Oracle Cloud Infrastructure Compute and Oracle Cloud Infrastructure Block Volume resources into the same logical grouping, known as a cluster placement group, to ensure that they're placed physically near one another in an availability domain. Collocating these resources can help you achieve the lowest latency possible between them. For more information, see Overview of Cluster Placement Groups, Cluster Placement Groups for Block Volume, and Creating an Instance.
