Sidecar Pattern

The Sidecar Pattern involves deploying a secondary component, called a "sidecar," alongside a primary application to enhance or support its functions. Think of it like a helpful companion attached to the main service, handling tasks such as logging, security, or configuration without altering the core application. This approach allows for modular improvements, easier updates, and better scalability, as the sidecar operates independently yet closely with the main application. It’s commonly used in microservices architectures to improve flexibility and maintainability without disrupting the main service.
