DevOps focuses on collaboration and automation across development and operations, DevSecOps extends this by embedding security into every stage of the pipeline, and CloudOps ensures the smooth operation and optimization of cloud infrastructure. Together, they represent different but complementary approaches to modern software delivery and IT management.
The Software Development Life Cycle (SDLC) is a structured process used by software engineers and project managers to design, develop, test, and deploy software systems. It provides a step-by-step framework that ensures software is built systematically, meets user requirements, and is delivered with high quality.
