How do you install Sitecore using SIF?

The installation of Sitecore using the Sitecore Installation Framework (SIF) is accomplished by running PowerShell scripts that leverage SIF cmdlets. SIF is specifically designed to automate the deployment of Sitecore environments and provide a scripted approach to installation, making it efficient and repeatable.

Using SIF allows for a structured installation process where configurations can be defined within PowerShell scripts. This method offers several advantages, such as the ability to easily modify configuration parameters, log installation progress, and maintain version control over installation definitions. Additionally, it integrates well with DevOps practices, allowing for automated deployments that can be part of continuous integration and continuous deployment (CI/CD) pipelines.

Other methods, such as a web-based installer or manual file extraction, do not provide the same level of automation or control as using SIF. Directly executing SQL scripts on the database is impractical for installing Sitecore as it does not consider dependencies or the environmental setup required for a successful installation. Therefore, using PowerShell scripts and SIF cmdlets is the recognized and recommended method for installing Sitecore.
