creates versioned deployable artifacts

standardizes development environment

Large-scale cluster management at Google with Borg - Verma et al. 2015

“Almost every task run under Borg contains a

built-in HTTP server that publishes information

about the health of the task and thousands of performance metrics”

Constraints are the contract that allows a platform to keep promises.

promises

Pi @bridgetkromhout

Everyone has a platform.

What promises can your platform keep?

Pi @bridgetkromhout

Minimum Viable Platform

1. Routing and load balancing 2. Backing services broker 3. Infrastructure orchestration 4. Health management, monitoring, and recovery 5. Reusable runtime environment repository 6. Log aggregation

structured contracts determine the promises a platform can keep
