SAP BTP Terminology
## A-G
| application                   | Software hosted on SAP BTP and used by business users to fulfill certain tasks. Ap- plications are created by developers and might make use of services offered on the platform.                                                                                                      |

| application router [page 439] | The single point-of-entry for an application running in the Cloud Foundry environment on SAP BTP. The application router is used to serve static content, authenticate users, rewrite URLs, and forward or proxy requests to other micro services while propagating user information. |
| availability                  | The durability and operational performance without failure of a system or component for an agreed amount of time, which is defined in the contract.                                                                                                                                   |
| availability zone             | A physically separate location with its own power supply, network, and cooling. Within a region, it serves as an individual failure domain. If one of the availability zones fails, the survival of the region is ensured.                                                            |
| block-hours                   | An hour regarded in terms of the run time of a single compute block. For example, a single compute block running for 10 hours would give 10 block-hours while 2 compute blocks running for the same period would give 20-block hours.                                                 |
