- Service Discovery: Finding the location of external services.
- Retry and Circuit Breaking: Handling failures in external calls.
- Security: Managing authentication and encryption (TLS) for outgoing traffic.
Benefits
- Simplifies the application code.
- Provides a consistent way to manage external dependencies across different services.
