The AWS Storage Layer

The tests mapped to this layer measure the usage and overall efficiency of the different storage services that are available to instances launched on the AWS cloud. The services include:

• AWS Elastic Block Store
• AWS Elastic File System

• AWS Simple Storage Service

Additionally, the layer also monitors the AWS Storage Gateways, using which on-premises software appliances connect with cloud-based storage, and reveals I/O processing bottlenecks and resource contentions experienced by the gateways.
