- 4. Waterfall Model ©Great Learning. All Rights Reserved. Unauthorized use or distribution prohibited Requirements Designing Implementation Testing Deployment Maintenance In the early year of software development when it was just coming up, waterfall model was used. Waterfall model is a very standard model used in many different fields, not just software development. It was very useful when the requirements were concrete and the development cycles were long.

- 9. What is DevOps? ©Great Learning. All Rights Reserved. Unauthorized use or distribution prohibited “DevOps is a set of practices that combines software development (Dev) and IT operations (Ops). It aims to shorten the systems development life cycle and provide continuous delivery with high software quality. DevOps is complementary with Agile software development; several DevOps aspects came from Agile methodology.”

- 14. DevOps Engineer ©Great Learning. All Rights Reserved. Unauthorized use or distribution prohibited - Basically a DevOps engineer is responsible for designing, maintaining the software development pipeline. He also makes sure that a software is deployed properly without any issues. A DevOps engineer knows how to automate processes and writing automation scripts. He also knows how to keep the whole infrastructure secure and robust. - A DevOps engineer has excellent communication skills that help him to convey ideas and exchange information between different teams. - On daily level, a DevOps engineer is responsible for makes sure scaling needs of cloud are fulfilled, optimisation, managing permissions, documentations.

- 16. Version Control - GIT
- 17. What is Version Control?
- 18. These days when software is developed, It is not developed with the mind-set that there will only be one piece of code that will be deployed and that’s it. These days smaller snippets of code are deployed in regular successions with regular feedbacks. This leads to many different versions of the code. And that creates a need to organise the code and all of its different version of it. This is where Version Control comes in. It is a practice of managing and storing different version of a source code. This is especially the case with Larger companies that have multiple projects and multiple teams working within it.

- 36. What is a Container?
- 37. What is a Container? Code Libraries Container Systems & Servers Containers are software that wrap up all the parts of a code and all its dependencies into a single deployable unit that can be used on different systems and servers.
- 38. What is Docker?
- 39. What is Docker? Docker is a tool that helps in developing, building, deploying and executing software in isolation. It does so by creating containers that completely wrap a software. The Isolation provided by container gives a layer of security to the containers.
