Helm is packaging, not a runtime plane. We will have following isses
POST /v1/orders to service B”.When to use a service mesh vs. no service mesh
| Service Mesh (e.g., Istio, Linkerd) | No Service Mesh (Vanilla K8s) | |
|---|---|---|
| Ideal for... | Complex microservice architectures with many services. | Small, simple applications or a limited number of services. |
| Security | Automatically enforces a zero-trust security model with mTLS and fine-grained authorization policies without touching application code. | Requires manual implementation and certificate management, which is difficult to scale and maintain. |
| Traffic Management | Provides advanced routing, retries, circuit breaking, and canary deployments. | Offers only basic Layer 4 load balancing. Advanced traffic control must be handled by an Ingress controller or complex network configurations. |
| Observability | Aggregates detailed metrics, distributed tracing, and logging for all service traffic out of the box. | Lacks comprehensive visibility into service-to-service communication. You must instrument applications with code to get basic telemetry. |
| Operational Overhead | Adds complexity and a learning curve for operators due to sidecar proxies and a control plane. | Simple to start, but operational complexity grows with each service you secure manually. |
