Overview
Logback is a Java logging library commonly used as an SLF4J backend. The 1.6.x line follows the 1.5.x and 1.4.x series, targets SLF4J 2.0.x, and separates logback-access into its own repository.

Key features
Provide a Java logging backend for SLF4J
The README describes Logback as a reliable, generic, fast, and flexible Java logging library and identifies the 1.6.x line with SLF4J 2.0.x.
Sources: [2]
Separate destinations, formatting, and rolling behavior from logging calls
Appenders, encoders, and rolling policies allow operational logging behavior to be configured independently from application logger calls.
Sources: [2]
Best fit
Fits Java services whose frameworks and libraries already log through SLF4J
It is a natural backend when service owners want one operational configuration for SLF4J-based logging across application modules and dependencies.
