What is a Sidecar Design Pattern?
The Sidecar Pattern is a design pattern used in software architecture, particularly in microservices environments. In this pattern, a “sidecar” container or process is deployed alongside a primary application container to extend or enhance its functionality.
- The sidecar container runs within the same execution environment as the primary application and typically provides supporting services such as logging, monitoring, security, or communication with other services.
- This pattern enables the primary application container to focus on its core functionality while offloading secondary tasks(logging, monitoring, security, service discovery, or communication proxies) to the sidecar, promoting modularity, scalability, and maintainability in distributed systems.
Sidecar Design Pattern for Microservices
The Sidecar Design Pattern is a key strategy in microservices architecture, involving the deployment of secondary containers, or “sidecars,” alongside microservice instances. These sidecar containers handle auxiliary tasks such as logging, monitoring, and security, enhancing the functionality and manageability of microservices.
