This foundational module demystifies DevOps and the modern Software Delivery Lifecycle (SDLC). You will learn how traditional, siloed development models evolved into collaborative, automated CI/CD pipelines. We will break down the stages of building, testing, and deploying software, explore the critical differences between Continuous Delivery and Continuous Deployment, and introduce the foundational security practices (DevSecOps) required to protect the software supply chain. The module culminates in a hands-on guided lab where you will map and automate a secure, end-to-end SDLC workflow.
