A New Experiment• Microservices?

• Decompose single “service” into the actual 40+ sub-services

• Any change to sub-service was a deployment of many

• Could it be a simple Spring Boot App in Docker (12 factor?)

• Backward compatible with existing service infrastructure.

• Code to Production w/o help from other Humans - Minutes not Days

Summary• Create a platform for docker deployments using shared and app-specific “localhost” helpers

— this was ours, yours SHOULD look different — adapt to change, don’t fight it.

• People don’t scale, use automation

• Docker - repeatable applications (environment portable apps)

• Chef - repeatable infrastructure (environment aware services)

• Jenkins - repeatable releases (pipelines)

• Delineate configuration concerns:

• Known at Compile time — Bake into Docker image

• Known at Boot time — Bake into Playbook/Launcher - parameter to Docker run

• Changes Anytime — Externalize (consul K/V, etcd, zookeeper)
