Understanding flavor classes¶

A flavor class is a grouping of flavors based on similar characteristics. Flavor classes streamline the process of choosing among available resources and pricing models.

When you create a cloud server, the server’s configuration is based on your answers to several questions:

Which server technology (virtual or OnMetal™) should the server use?

Compare Flavor classes for virtual cloud servers and Flavor classes for OnMetal cloud servers to help you consider the differences.
In which region will the server be based?

Most flavor classes are available everywhere, but a few are only available in some regions. Checking for regional availability of flavor classes shows how to tell which flavor classes are available in your server’s region.
Of the flavor classes available to that server technology, which is best suited to the workload planned for the new server?
Of the flavors available within that flavor class, which provides the right-sized and right-priced configuration?

Choose a flavor class based on your expectations of the server’s primary workload. For example, you can choose a flavor class optimized for I/O if you expect the cloud server to support an I/O-intensive workload. Within the flavor class, you then choose a specific flavor based on the configuration options you prefer. You can learn more about this at Choosing a flavor class.
