What does IDP stand for in platform engineering?
IDP stands for Internal Developer Platform — a self-service layer built on top of infrastructure that allows development teams to provision environments, deploy code, and manage services without needing ops intervention.

What does 'compute abstraction' mean as an IDP component?
Compute abstraction hides whether workloads run on VMs, Kubernetes, or serverless functions. Developers say 'deploy my service' — the IDP chooses and manages the compute layer. Tools like Heroku and internal platforms provide this.

Which IDP component is responsible for storing and injecting credentials, API keys, and certificates securely?
Secrets management handles secure storage and injection of credentials, API keys, tokens, and certificates. Tools like HashiCorp Vault, AWS Secrets Manager, or Kubernetes Secrets provide this capability.

A developer wants to spin up a 'staging' copy of their service for QA testing. Which IDP capability does this fall under?
Environment management allows developers to create, configure, and tear down environments (dev, staging, prod) on demand. A good IDP makes spinning up ephemeral environments for testing a self-service operation.

What is the primary goal of building an Internal Developer Platform?
The primary goal of an IDP is to reduce cognitive load — developers shouldn't need to understand Kubernetes internals or cloud networking to deploy a service. The IDP abstracts that complexity behind a simple interface.
