Introduction In the world of software development, microservices architectures have become synonymous with scalability, agility, and resilience. Instead of one monolithic application, microservices break down applications into smaller, independently deployable services. This approach offers many benefits, but it significantly increases the complexities of authorization. Authorization controls who or what can access specific resources or perform certain actions within your system. In a microservices world, where numerous services interact, ensuring robust and reliable authorization is paramount for application security.
