Tips

• A very mature software deployment pipeline is an absolute requirement for any microservices architeture

• Indicators of a good pipeline maturity:

  • Amount of manual intervention required
  • Amount of automated tests
  • Automatic provisioning of environments
  • Monitoring

• Problems to take care on distributed systems: Tracing, monitoring, log aggreagation, resiience

• Improve our lead time and reducing the batch size of our releases

• Each microservice should have its own separate database

• Strangler Pattern: start with a monolith and a relational database and break up to microservices and different DBs later
