Compute segregation

OpenStack is designed to scale massively to respond to the growth of the infrastructure size and user demand. As the compute service is the workhorse of the cloud infrastructure, designing for compute layer scalability and business continuity is a must. Defining a compute segregation strategy will help you understand your private cloud infrastructure limits and forecast user compute demands – that’s what will be explored in the following section.

Infrastructure segregation

Depending on the available compute farm resources and inventory specifications, as well as the hypervisors to be used, OpenStack exposes a variety of compute segregation mechanisms that can be leveraged, including Availability Zones, Regions, Cells, and Host Aggregates. Each of the previous concepts will be detailed in the following section.

Regions

A region in the OpenStack glossary presents a fully independent OpenStack deployment. From operational and management perspectives...
