The Cost of Not Having Self-Service#

A developer needs a PostgreSQL database. They file a ticket. It sits in a backlog for two days. A DBA provisions it, sends credentials via Slack DM. Elapsed time: 3 days. Actual need: 5 minutes of configuration. Multiply across every database, cache, queue, and namespace, and manual provisioning becomes the single largest drag on velocity. Self-service lets developers provision pre-approved resources directly, within guardrails the platform team defines.

What Crossplane Does#

Crossplane extends Kubernetes to provision and manage cloud infrastructure using the Kubernetes API. Instead of writing Terraform and running apply, you write Kubernetes manifests and kubectl apply them. Crossplane controllers reconcile the desired state with the actual cloud resources.

The real value is not replacing Terraform — it is building abstractions. Platform teams define custom resource types (like DatabaseClaim) that developers consume without knowing whether they are getting RDS, CloudSQL, or Azure Database. The composition layer maps the simple claim to the actual cloud resources.
