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

Summary

• Create a shared 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.

• Take people out of the release process

- Docker - repeatable applications - Chef - repeatable infrastructure — Environment aware - Jenkins - repeatable releases

• 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)
