Question

This question explores Cloud Computing and addresses practical considerations related to: What’s the difference between service mesh routing and standard ingress controllers?

Q&A Network · Accepted Answer

Service mesh routing and standard ingress controllers both manage traffic within cloud environments, but they serve different purposes and operate at different layers. Service mesh routing provides fine-grained, application-level traffic management, security, and observability across microservices, while ingress controllers manage external traffic entering a Kubernetes cluster, primarily focusing on HTTP/HTTPS routing.

Example Concept: Service mesh routing, such as Istio or Linkerd, operates at the application layer (Layer 7) to provide advanced traffic management, including retries, circuit breaking, and load balancing between microservices. It enables detailed observability and security policies like mTLS. In contrast, ingress controllers, like NGINX or Traefik, handle incoming requests at the edge of a Kubernetes cluster, routing them to the appropriate services based on hostnames or paths, and often provide SSL termination and basic load balancing.

ADDITIONAL COMMENT:

Service meshes are ideal for complex microservices architectures requiring detailed traffic policies and security.
Ingress controllers are simpler and focus on routing external traffic to internal services efficiently.
Both can be used together, with ingress controllers handling external traffic and service meshes managing internal service-to-service communication.
Consider the operational overhead and complexity when implementing a service mesh, as it introduces additional components and configurations.
