"Netflix is actually a log generating application that just happens to stream movies"
Building a service/Microservice is itself easy. Scaling it on the cloud is not that hard either but operating, maintaining and iterating a production large scale service is not just about linearisation. As Cockcroft points out, telemetry and monitoring is the most important aspect of building Microservices
We discuss 5 patterns that any serious Microservice should have:
- Canary (an endpoint reporting health of underlying dependencies)
- IO monitor (measuring all calls from Microservice to external dependencies)
- A circuit breaker
- An ActivityId-Propagator
- An exception and short timeout retry policy
