Infrastructure Code Continuous Delivery Concepts

• Continuous Delivery
• Infrastructure as Code Concepts
• Infrastructure Code Testing

Overview

The delivery pipeline metaphor describes how a change in the infrastructure code progresses from the person that makes the change all the way to production.

Reconcile with Continuous Delivery.

Infrastructure Delivery Pipeline

A infrastructure delivery pipeline consists in multiple types of activities, grouped in stages:

Activities

Build

The build stage compiles application code and makes the code available for use for other stages. Building is usually done once in a pipeline, every time the source code changes. As result, artifacts may be published in a repository.

Promote

Promotion means moving code between delivery stages.

Apply

Infrastructure code tools are executed and infrastructure resources are created based on the code. The infrastructure resources are created in different environments, corresponding to the pipeline stage the activity belongs to: stage testing, integration, production.
