How deeply does Effective Platform Engineering cover persistent data resource?

Defines resource categories and explains operator-based provisioning, while noting its distinct operational lifecycle and learning curve.

Persistent data resource

As explained in Effective Platform Engineering

A persistent data resource is infrastructure that stores or manages data across application restarts, such as a database, message queue, file share, or cache.

A persistent data resource stores or manages data across application restarts, including databases, message queues, file shares, and high-performance caches. Platform teams expose these resources through an API so development teams receive a consistent provisioning experience while platform engineers retain operational responsibility. section 8.4.3

An operator-backed platform pattern typically:

Extends the Kubernetes API as the developer provisioning interface. section 8.4.3
Manages the operational lifecycle through infrastructure operators rather than treating resources as a simple wrapper for all infrastructure. section 8.4.3
Uses tools such as Crossplane, AWS ACK, Operator SDK, or Terraform Operator, each with an associated learning curve. section 8.4.3

Platform API for data infrastructure

An API team requests a database, message queue, file share, or high-performance cache through the Kubernetes API; the platform team provisions and operates the underlying resource through an operator. section 8.4.3

infrastructure operatoruses · An infrastructure operator is a controller that provisions and manages infrastructure resources through a platform control-plane API.
state persistenceincludes · State persistence is the retention of data or application state beyond the operation, session, or process in which it was created, so it remains available for later use.
databaseincludes · A database is an organized collection of persistent data managed by software for storage, retrieval, querying, and modification.
