+# Image Builder
+
+AWS service automating the creation, management, and deployment of customized AMIs or Docker images.
+
+1. [TL;DR](#tldr)
+1. [Further readings](#further-readings)
+   1. [Sources](#sources)
+
+## TL;DR
+
+Images created by Image Builder in one's account are owned by that account.
+
+Leverages AWS' Task Orchestrator and Executor component management application.<br/>
+For AMIs, it:
+
+1. Creates EC2 instances for building and validation.
+1. Creates a snapshots of the result.
+1. Terminates the EC2 instances used for building.
+1. Uses that snapshot to create new EC2 instances for testing.
+
+For containers, it:
+
+1. Creates EC2 instances for building and validation.
+1. Builds container images.
+1. Runs containers from the images for testing.
+1. Terminates the EC2 instances used for building.

+
+Image Builder costs **nothing** to create custom AMI or container images per se.<br/>
+However, standard pricing applies for the other services that are used by or in the process, like EC2 instances, EBS
+volumes, and ECR storage.
+
+Components can be specified **at most once** in an image recipe.
+
+Steps:

+1. \[optional] Create a new _infrastructure configuration_.
