Agile Methodologies and DevOps Practices

The video tutorial discusses the Software Development Life Cycle (SDLC), a process for building high-quality software. It covers the phases of SDLC, including planning, designing, development, testing, deployment, and maintenance. The video contrasts the traditional Waterfall model with the more flexible Agile methodology, highlighting Agile's adaptability and iterative approach. It also introduces DevOps and CI/CD, emphasizing collaboration and automation in software development.

What is the primary purpose of the Software Development Life Cycle (SDLC)?

• To standardize the stages of building high-quality software

• To create a random process for software development

• To eliminate the need for planning in software projects

• To ensure software is developed without any testing
