Communication

Sidecar Pattern

Description

Deploys components of an application into a separate process or container to provide isolation and encapsulation. This allows you to attach functionality like logging, monitoring, or networking to a service without changing the service code.

Where to use

  • Service Mesh (Istio/Linkerd).
  • \n
  • Centralized logging agents.
  • \n
  • SSL termination.

Real World Example

A Kubernetes Pod contains two containers: the Node.js API (Main) and Envopy Proxy (Sidecar). All network traffic flows through Envoy.

Code Example
