Keycloak

Keycloak 26.4.7 on Ubuntu 24.04 with Free Maintenance Support by ATH Infosystems Keycloak on AWS (EC2 Deployment)

Maintained by ATH Infosystems

This AWS Marketplace AMI provides a self-managed Keycloak Identity and Access Management (IAM) server designed for teams that want direct control over authentication, authorization, and identity federation in AWS.

The image is built, packaged, and validated by ATH Infosystems to ensure predictable behavior on Amazon EC2. It is intended for engineering teams that prefer owning the runtime, security posture, and upgrade path, rather than relying on a managed SaaS identity service.

What This Is (and What It Is Not)

This offering is: .A ready-to-run Keycloak server on EC2. .Fully self-managed inside your AWS account. .Based on upstream, open-source Keycloak. .Designed for production use, not demos.

It is not a hosted identity service, and it does not abstract infrastructure away. You get full access, full responsibility, and complete flexibility.

Common Real-World Use Cases

Teams typically use this AMI for: .Single Sign-On (SSO) across internal tools, dashboards, and custom applications .Central IAM for microservices and APIs running on AWS .Replacing legacy authentication systems with OIDC or SAML .Securing CI/CD tools, internal admin panels, and developer platforms .Identity federation with existing Active Directory or LDAP settings .Multi-tenant SaaS authentication, where identity isolation matters

This AMI is commonly deployed by platform teams, DevSecOps groups, and enterprises operating under compliance or data residency constraints.

Protocols and Identity Standards

Keycloak in this AMI supports: .OpenID Connect (OIDC) .OAuth 2.0 (standard authorization flows) .SAML 2.0

Identity features include: .User federation with LDAP and Active Directory .Role-based and attribute-based access control .Realm-based isolation for multi-application setups .Token-based authentication for APIs and services

All configuration is performed using the native Keycloak admin console or supported APIs.

Base System and Runtime

.Operating System: Ubuntu 24.04 LTS .Java runtime installed and configured for Keycloak .Keycloak packaged from the official open-source distribution .Database support for PostgreSQL or MySQL

The system is intentionally kept close to upstream defaults, making it easier for engineers already familiar with Keycloak to operate and maintain.

Deployment Model on AWS

This AMI follows a straightforward EC2 deployment model: .Runs entirely inside your VPC .Works with AWS Security Groups, IAM, and Load Balancers .Can be used as a single-node deployment or expanded into high availability .Compatible with Infrastructure as Code and CI/CD pipelines

Teams often front the deployment with an Application Load Balancer and use an external database for high availability.

Security and Control

Security is handled in a way that aligns with standard AWS best practices: .No outbound dependencies required for core functionality .TLS termination supported at the instance or load balancer level .Logs and audit data remain within your AWS account .No vendor access to runtime or identity data

This makes the AMI suitable for regulated environments, internal enterprise networks, and zero-trust architectures.

Operations and Observability

The deployment integrates cleanly with standard AWS operations: .Supports CloudWatch logging and monitoring .Supports AMI snapshots and database backups .Predictable startup and runtime behavior .Designed for repeatable builds across environments .No managed control plane or hidden services .Full control over updates and maintenance schedules
