19. Immutable Infrastructure
20. Immutable Infrastructure • Start with a base image • Lightly Optimized Base image • Security Updates • Infrastructure Packages • Release Process • Canary with smaller & internal applications • Release weekly • Faster release process for critical updates
21. Immutable Infrastructure • Install Application Package • Using OS Package Manager • Compile that into new AMI • Ship to all AWS Regions
22. Immutable Infrastructure • Docker • Already Immutable • Can be built using the same OS package system • Configuration Management • Don’t - Seriously
23. Immutable Infrastructure Docker – below the surface What about the base OS? More…
24. Tools • Package Builder • Gradle • OS Tool (rpmbuild / builddeb) • Image Builder • Aminator • Packer • Docker –build • Deployments • Spinnaker • Jenkins • Discovery • Eureka • Zookeeper • Consul • Kubernetes • Docker
25. Benefits Simpler Operations
26. Benefits Continuous Deployments Design Development Alpha Testing Beta Testing Release Development
27. Benefits Faster Startup Times
28. Benefits In sync Configurations
29. Benefits Same Image Everywhere
30. Benefits Security
31. Benefits No More Snowflakes
