应用需求

The following requirements were decided upon to define what OpenTelemetry (OTel) signals the application will produce & when support for future SDKs should be added:

1. Every supported language that has a GA Traces or Metrics SDK must have at least 1 service example.

2. Mobile support (Swift) is not an initial priority and not included in the above requirement.

3. Application processes must be language independent.

4. gRPC is preferred where available and HTTP is to be used where it is not.

5. Services should be architected to be modular components that can be switched out.

6. Individual services can and should be encouraged to have multiple language options available.

7. The architecture must allow for the possible integration of platform generic components like a database, queue, or blob storage.

8. There is no requirement for a particular component type - at least 1 generic component should be present in general.

9. A load generator must be provided to simulate user load against the demo.
