Design pattern where helper components are deployed alongside main applications. Like having a personal assistant that helps with specific tasks while you focus on your main work.
Applications use sidecar containers to handle logging, monitoring, and security without modifying the main application code.
The Sidecar Pattern is an application architecture pattern (commonly implemented with containers) rather than a single cloud service. It’s typically realized on managed Kubernetes or container platforms across providers (e.g., EKS/AKS/GKE/OKE) by running an additional container or process alongside the main app to provide capabilities like proxying, logging, metrics, or security.
