## Description
The Sidecar pattern deploys components into a separate process or container to provide isolation and encapsulation. The sidecar runs alongside the main application and provides features like monitoring, logging, configuration, or networking. This keeps the main application focused on business logic while the sidecar handles cross-cutting concerns.


## Use Cases
Use when you want to separate cross-cutting concerns from the main application or when you need to add features without modifying the main application code.'





## Trade-offs


### Advantages

- Separation of concerns

- Language and framework independence

- Easy to add and remove features

- Isolated lifecycle management




### Considerations & Drawbacks

- Additional infrastructure complexity

- Resource overhead

- Debugging across processes
