Environment architecture
Our example ChatOps program will need to interact with several services to provide information to users.
To enable this, we have built a more robust version of the Petstore application that we built in our previous chapters. This version does the following:
- Implements create, read, update and delete (CRUD).
- Is gRPC based.
- Has deeper Open Telemetry tracing that flows through RPC calls and records events.
- Deeper metrics that can be used to inform Prometheus alarms.
- Replaces logging with tracing events.
- All errors are automatically added to traces.
- Traces can be turned on by a client.
- Traces are sampled by default but can be changed via an RPC.
You can find this new Petstore here: https://github.com/PacktPublishing/Go-for-DevOps/tree/rev0/chapter/11/petstore. There is a README file that details the architecture if you want to dive into the details, but you do not need to for this chapter.
Our new Petstore is more...
