  • They need to create a centralized entry point for routing requests to various microservices.
  • Ensuring consistent security measures across microservices, including authentication checks, poses a challenge.
  • Extending the token validity period to 24 hours based on the last activity is another challenge they face.

Our Solution

Based on challenges in Microservices migration, we provide a solution to them to solve their problems instantly:

  • We leverage Zuul as an API gateway for Microservices to streamline service routing and management.
  • Our solution includes robust authentication checks, ensuring secure access to microservices.
  • We implement an approach where token validity, stored in a Redis cache, is extended based on user activity.
  • We seamlessly integrate Kubernetes service discovery with Zuul for efficient and dynamic service routing.
