Overview
In the context of distributed systems and sidecars, the adapter pattern is used to provide a consistent interface to a service, regardless of its internal implementation. It 'adapts' the service's output to a standard format.
Example
A monitoring adapter might collect metrics from an application in its native format and expose them in a format that a central monitoring system (like Prometheus) can understand.
Benefits
- Enables interoperability between diverse systems.
- Decouples the application from the specific requirements of external tools.
