Introduction &amp; Overview<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">What is Prefect?<\/h3>\n\n\n\n<p><strong>Prefect<\/strong> is an open-source data workflow orchestration tool designed to build, run, and monitor complex pipelines with ease. It enables teams to automate and manage workflows in a scalable, observable, and fault-tolerant manner. Prefect supports dynamic scheduling, retries, caching, and parameterization\u2014all critical features for maintaining robust pipelines in DevSecOps environments.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">History or Background<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Founded:<\/strong> 2018 by Jeremiah Lowin<\/li>\n\n\n\n<li><strong>Initial Release:<\/strong> 2019<\/li>\n\n\n\n<li><strong>Latest Evolution:<\/strong> Prefect 2.0, a significant redesign for more flexibility and cloud-native compatibility<\/li>\n\n\n\n<li><strong>Mission:<\/strong> \u201cThe easiest way to coordinate dataflows without losing control.\u201d<\/li>\n<\/ul>\n\n\n\n<p>Originally targeting data engineering tasks, Prefect has evolved to support broader use cases including <strong>CI\/CD orchestration, security automation<\/strong>, and <strong>compliance workflows<\/strong>\u2014making it relevant in DevSecOps.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Why is it Relevant in DevSecOps?<\/h3>\n\n\n\n<p>DevSecOps practices rely heavily on <strong>automated, secure, and observable pipelines<\/strong> to deliver value continuously and securely.
