“Dorothy: Toto, I’ve a feeling we’re not in Kansas anymore.” Deployments of OpenStack in private cloud environments poses a set of requirements in the network architecture that are often completely different from those of a public cloud. Even though multi-tenancy is still a key requirement; regulatory issues, compliance, and business rules often dictate significantly different requirements. Whereas in public clouds, tenant networks are isolated in private address space, in private clouds interconnecting between cloud applications and existing resources needs to be achieved in several different ways. IP address management is often centralized and it is combined with policy and configuration management, especially for non-Linux workloads. Separation of networks is not just a tenant function, but often a regulatory function. During this talk we will outline several of the use cases that dominate the discussion in private cloud deployments.
