Self-Service Infrastructure, Automation, and Measuring the Platform

Crossplane compositions so teams claim databases and buckets through Kubernetes APIs, platform automation in Go and Python, and measuring the platform with DORA, developer experience, and cost.

The last big ticket in ShopLite's charter is 'I need a database'. This stage turns cloud resources into self-service Kubernetes APIs with Crossplane, adds the glue code every platform team ends up writing (in Go and Python), and closes the loop by measuring whether the platform actually makes teams faster.

+ ShopLite gains: Crossplane XRDs and compositions for PostgreSQL and S3, a shopctl Go CLI and Python automation, and a platform metrics dashboard (DORA, adoption, cost)

    Compositions: A Self-Service Database API

    A team requests `kind: PostgreSQLInstance` with `size: small` and gets an RDS database, parameter group, subnet group, and credentials Secret, all within platform standards.
