Imagine a web application that logs all incoming requests and responses for and sends them to a central observability platform for debugging and analysis. Instead of adding the code to send the logs directly into the application, a sidecar service can be attached to handle this task separately. This enables the main application to focus on its primary function, while the sidecar takes care of the logging.
The sidecar pattern enables a cleaner and more modular architecture, separating concerns and improving the overall observability and manageability of applications.
