Flavor maps express the deployment sizes that make sense for your environment. One example might be small for 1 CPU and 2 GB memory and large for 2 CPUs and 8 GB memory for a vCenter account in a named data center and t2.nano for an Amazon Web Services account in a named region.
A flavor mapping associates a defined cloud account /region with one or more data-collected sizing options or instance types. For example, a flavor of small might equate to a specific number of CPUs, allowing you to scale your resources to the requirements of your target workload. Flavor mappings are regional settings.
