Service Mesh Concepts and Benefits

Imagine you have many tiny services, all talking to each other. A Service Mesh is a dedicated infrastructure layer that handles communication between these services.

• It's like a 'network for services'.
• It doesn't change your application code.
• It helps manage, secure, and observe service-to-service communication.

In a microservices architecture, services constantly communicate. Without a service mesh, each service needs to implement logic for:

• Load balancing: Distributing requests.
• Retries: Handling temporary failures.
• Security: Encrypting communication (mTLS).
• Observability: Collecting metrics and traces.

This adds complexity to every service.
