Identity Governance (Keycloak, PostgreSQL, React, Go, Docker) overview

An identity governance and administration platform managing user lifecycle, access certifications, and privilege reviews across the organization. Keycloak provides the identity provider with SAML, OIDC, and LDAP federation supporting thousands of enterprise applications. Go microservices implement access certification campaigns, role mining algorithms, and segregation-of-duties policy enforcement. PostgreSQL stores identity records, entitlement catalogs, certification decisions, and audit logs with temporal tables for historical queries. React powers the admin console with organizational hierarchy views, access request workflows, and certification campaign dashboards. Docker containers ensure consistent deployment across identity zones. The tradeoff is maintaining accurate role definitions as the organization evolves and the performance impact of evaluating complex entitlement policies at authentication time.
