Standard change

As explained in Infrastructure as Code, Patterns and Practices: With examples in Python and Terraform

A standard change is a routine, predictable modification that follows an established delivery approach.

A standard change is a commonly implemented infrastructure modification with predictable behavior, an established delivery approach, and a defined rollback plan. Its repeatability makes it a candidate for continuous deployment rather than repeated manual approval. section 7.1.4

Treat a change as standard when it has:

  • A routine, well-understood implementation that automation can test consistently. section 7.1.4
  • A reliable runbook for correcting failure or rolling back without impact. section 7.1.4
  • A delivery pipeline that can identify the change and bypass manual production approval. section 7.1.4

Infrastructure examples

Upgrading container images in an orchestrator, deploying a new queue, adding a monitoring alert, or adding servers to a scaling group can be standard changes when their behavior and rollback are established. section 7.1.4

How Infrastructure as Code, Patterns and Practices: With examples in Python and Terraform covers it

How deep it goes
Defines selection criteria, examples, pipeline behavior, and rollback expectations but does not detail implementation code.
Examples
Uses container upgrades, queues, monitoring alerts, scaling-group servers, and commit-message-driven pipeline routing.
What it assumes
Assumes infrastructure as code, automated testing, delivery pipelines, peer review, and operational rollback runbooks.
What you can do after
Operate continuous deployment for predictable infrastructure changes with automated checks and a documented rollback path.
How it connects
Connects infrastructure as code, continuous deployment, manual approval, rollback plans, and emergency changes.
