You are tasked with ensuring secure communication between microservices in a distributed system. How can JWT be used to ensure that the calls between microservices are authorized?
- Attach JWT tokens to each microservice request and verify them to ensure authorized access
- Encrypt all microservice calls using SSL/TLS for security
- Store user roles in a centralized database for validation
- Use API keys to validate each microservice call
In a microservices architecture, JWT can be used to ensure authorized communication. Each microservice request is attached with a JWT token, and the receiving microservice verifies the token to ensure that the call is authorized. This approach provides a lightweight and scalable method for enforcing security and authorization between microservices.
