6. What makes a microservice? • Single business capability. • Stateless - a failure of the microservice should not bring down the whole system. • Federated data - must be responsible for its own data.
7. Benefits • Loosely coupled system. • Each unit is simple and focuses on doing one thing well. • Each service can be built using the best and most appropriate tool for the job. • Multiple developers and teams can deliver relatively independently of each other. • Good for continuous delivery, allowing frequent releases whilst keeping the rest of the system available and stable.
8. New Worries • Substantial DevOps Skills Required • Distributed System Complexity • Monitoring. Harder than monitoring monoliths. • Maintenance Burden.
9. Should my team migrate to microservices ? • Ensure your team is up to the task. Dev and Ops. • Ensure you have the resources. Don’t miss deadline. • Start small and make adjustments as needed. • Keep It Simple Stupid. • Employ tools that help the process. Weaveworks, Bamboo, GKE e.t.c. • Take a pragmatic approach. Common sense first.
