All instances are provisioned within a specific plan tier. When provisioning on Crunchy Bridge you will specify which infrastructure provider and region you wish to provision in, as well as the instance type and amount of storage.
Instances are divided into tiers which map to specific instance lines and inherit different performance characteristics.
The available tiers are:
Hobby - Intended for smaller workloads and early stage applications.
Standard - Intended for large scale production workloads.
Memory Optimized - Intended for applications that need to keep a larger working set of data in memory. Only available on AWS currently
