Designing a Distributed Authorization Server Architecture
Visual Overview: graph LR subgraph JWT Token A[Header] --> B[Payload] --> C[Signature] end A --> D["{ alg: RS256, typ: JWT }"] B --> E["{ sub, iss, exp, iat, ... }"] C --> F["HMACSHA256(base64(header) + base64(payload), secret)"] style A fill:#667eea,color:#fff style B fill:#764ba2,color:#fff style C fill:#f093fb,color:#fff In the modern era of cloud-native applications and microservices architectures, the need for scalable, secure, and efficient authorization systems has never been greater. An Authorization Server (AS) plays a critical role in enforcing access control policies, issuing tokens, and managing user sessions. However, as the scale of applications grows, the traditional monolithic approach to building an Authorization Server becomes a bottleneck. This is where a distributed architecture comes into play, enabling high availability, scalability, and fault tolerance. ...
