Service Specific Authorization
Service Specific Authorization is a security design pattern where authorization logic is embedded directly within individual microservices or services, rather than centralized in a single system. It involves each service making its own access control decisions based on user roles, permissions, and context, often using policies defined within the service's code or configuration. This approach contrasts with centralized authorization models and is commonly used in distributed architectures like microservices to enforce fine-grained, domain-specific access rules.
Developers should learn and use Service Specific Authorization when building distributed systems, particularly microservices, where services have unique business logic and access requirements that are best understood locally. It is ideal for scenarios requiring high autonomy, scalability, and low latency, as it avoids bottlenecks from a central authorization server and allows services to evolve independently. Use cases include e-commerce platforms with separate services for orders, payments, and inventory, each needing tailored authorization checks.
