SDLC (Software development life cycle) needs to be understood while discussing DevOps. If you want to work in a Software development organization, you have to understand SDLC.
Definition of Software development life cycle:
A process followed by the Software or IT industry.
The phase of SDLC:
- Design
- Develop
- Test
The end goal of SDLC:
Deliver a high-quality product.
For example, ideation to launch of example.com, there is maybe these phases:
- Planning (gathering requirements/feedback from customers and so on)
- Defining (documenting the requirements/software specification and so on)
- Designing (HLD/LLD: high/low-level design)
- Building
- Testing
- Deploying
How?
For example, during the building of the software, developers put the code to the central repository (git), then testing needs to be done by a QA tester (to the staging server) and then finally it is deployed to the production server. DevOps fastens the process, making it quick and automated.
You need to remember, that a DevOps engineer doesn’t build, test, and deploy the software, he automates these processes.
