An Installation Framework is a structured approach used to set up software applications or systems. It provides guidelines and tools that help developers and system administrators efficiently install, configure, and manage software. This framework often includes scripts, templates, and best practices to ensure a smooth installation process. These frameworks can vary in complexity and are designed for different environments, such as Windows, Linux, or macOS. Popular examples include Ansible, Chef, and Puppet, which automate the installation and configuration of software, making it easier to maintain consistency across multiple systems.
