This guide is for engineering managers, DevOps engineers, and platform teams who need a structured way to compare options such as ClearCase, Git, SVN, Perforce, and Mercurial.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Originally published on 2010-09-17; fully revised and updated.<\/em><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-4357\" src=\"https:\/\/www.devopsschool.com\/blog\/wp-content\/uploads\/2010\/09\/configuration-management.png\" alt=\"configuration-management-tools-discussion\" width=\"600\" height=\"400\" srcset=\"https:\/\/www.devopsschool.com\/blog\/wp-content\/uploads\/2010\/09\/configuration-management.png 600w, https:\/\/www.devopsschool.com\/blog\/wp-content\/uploads\/2010\/09\/configuration-management-300x200.png 300w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What this decision includes (and what it does not)<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">This article focuses on <strong>SCM\/version control tooling<\/strong> (repository model, branching, history, governance, and integration).
