Introduction

Keycloak is a popular open-source solution for identity and access management, providing single sign-on, identity federation, social login, and more. Deploying Keycloak in a production environment requires careful planning to ensure security, scalability, and high availability.

In this detailed guide, we will walk through deploying Keycloak on AWS Elastic Container Service (ECS) with Fargate using Terraform. This serverless approach eliminates the need to manage the underlying infrastructure, allowing you to focus on your application.

Why this approach?

Using ECS with Fargate provides a serverless container platform that eliminates the need to provision and manage servers. Combined with Terraform for infrastructure as code, this approach offers the ideal balance of control, scalability, and operational simplicity.
