11. Review: Why microservices?
• Complexity management
• Fine grained control
• Fault isolation
• Minimize deployment risk
• Scalable team structure
• Scalable performance
• Isolate technical debt

12. Development needs for microservices
• Build, run & test a single microservice
• Live reload for a single microservice
• Build, run & test multiple microservices, a
microservices application
• Live reload across the microservices application

13. Why Docker?
• It’s ubiquitous
• Infrastructure as code
• It’s a script for building a microservice
• Tech stack agnostic
• Standardize our environment
• Package our microservices
• Publish our microservices
• Run our microservices

14. Why Docker-Compose?
• It’s convenient
• Scalable development workflow
• It converts many commands to one
• It records configuration
• Infrastructure as code
• It’s a script for building a microservices application
• Development only, Kubernetes for production
