+# Infrastructure
+
+The infrastructure for running the WCA Registration Service.
+
+## Setup
+
+First, install terraform and initialize with:
+
+```
+terraform init
+terraform workspace select prod || terraform workspace new prod
+```
+
+To apply changes run:
+
+```
+terraform apply
+```
+
+## Details
+
+The WCA Registration System runs on a single Docker container
+
+### App
+
+We use ECS to run the app container(s). Currently the service runs on one t3.small instance which can house up to two containers
+
+### Deployment
+
+To automate deployment we use a CodePipeline that is triggered by pushing a new app image to ECR. The pipeline:
+
+  1. Sources the new ECR image arn.
+  2. Prepares files necessary for CodeDeploy (`appspec.yaml`, `taskdef.json`)
+  3. Triggers CodeDeploy to do Blue/Green deployment.
