Keycloak is an open-source identity and access management (IAM) solution. It handles authentication, authorization, single sign-on (SSO), user federation, and token management. When deployed on Infrastructure as a Service (IaaS), Keycloak gains elasticity, resilience, and scalability without custom hardware or heavy capital expense. You get IAM features backed by your cloud provider’s compute, storage, and networking—ready to deploy where your workloads live.
Running Keycloak on IaaS means you can spin up secure identity services in minutes. You can integrate with LDAP, Active Directory, OAuth2, OpenID Connect, and SAML without worrying about underlying server maintenance. Automated backups, high availability, and multi-region failover become configuration choices instead of engineering projects. Frequent updates, patched builds, and scaling changes can be pushed from your IaaS console without downtime.
Security hardening is simplified. Access controls for administrative endpoints are enforced through both Keycloak’s realms and the IaaS provider’s firewall rules. Audit logs can be streamed directly into cloud-native logging systems, connected to SIEM platforms, and monitored in real time. TLS termination, secrets management, and private networking work seamlessly when you combine Keycloak’s IAM stack with your cloud’s security features.
