sidecar
n.n. a secondary tool or service that runs alongside a main computer program to help it work better. It handles extra tasks like security or logging so the main program can focus on its own job.
n. a separate container or process that runs alongside a primary application to provide auxiliary features or infrastructure support. This pattern allows for the modular separation of concerns, such as monitoring or network proxying, without modifying the core application code.
The developer added a sidecar to handle the application's security logs.
In a microservices architecture, a sidecar often manages the communication between different services to ensure reliable data transfer.
By offloading encryption and authentication to a sidecar proxy, the engineering team simplified the deployment pipeline and ensured consistent security policies across all their cloud-native applications.
From side + car.
Commonly used in the context of container orchestration and microservices architecture.
