Fabric
Fabric is a Python library and command-line tool for streamlining application deployment and system administration tasks over SSH. It provides a high-level interface for executing shell commands on remote servers, managing file transfers, and automating repetitive operations across multiple machines. It simplifies tasks like deploying code, managing configurations, and running maintenance scripts in distributed environments.
Developers should learn Fabric when they need to automate deployment, server management, or administrative tasks in Python-based projects, especially for web applications or cloud infrastructure. It is particularly useful for DevOps engineers, system administrators, and backend developers working with remote servers, as it reduces manual SSH work and enables consistent, repeatable automation across environments like staging and production.
