The text outlines the deployment of a CMS application on AWS using ECS Fargate, which required an external OAuth server due to the inability to use Netlify's Identity Service. Utilizing a polyglot approach, the OAuth server is implemented in Go, while the infrastructure is managed with a Typescript Pulumi project. The deployment process includes setting up environment variables for authentication, configuring OAuth server callbacks for repository providers like GitHub, GitLab, and Bitbucket, and establishing secure communication using HTTPS through an Application Load Balancer. The text also describes the creation of a certificate for the OAuth server, the use of Pulumi's random package to generate session secrets, and the automation of the build process using GitHub Actions. Finally, it emphasizes updating the CMS configuration file to integrate the CMS and OAuth server, allowing users to log in via GitHub, thereby completing the deployment process.
