Handling multiple tenants

There are many different ways to work with multiple tenants on OpenShift, with the most obvious one being to have a single cluster for each tenant. However, this is not always possible or the best option: having dedicated hardware and a platform for every tenant can be costly, difficult to maintain, and not efficient. With shared clusters, multiple workloads from different tenants share the same computing capacity, enabling more efficient computing usage.

OpenShift can provide isolation for objects, computing, network, and other hardware resources for each tenant, ensuring they are isolated from each other. In the next section, we are going to look at the different types of isolation and how to utilize them.

Multitenancy in OpenShift

When it comes to multitenancy on OpenShift, several objects are involved. The following table shows some important resources that provide multi-tenant capabilities, all of which we are going to cover in this chapter:
