DevOps Life Cycle and Tools Quiz

Study Notes

Software development traditionally consisted of two separate teams: development and operations, with distinct roles and responsibilities.
The development team designed and built systems, while the operations team tested and implemented codes.
The operations team provided valuable feedback to the development team regarding bugs and required rework, but the teams operated independently.
This approach often resulted in extended timelines and delayed software development cycles due to the need for constant feedback from the operations team.
The "DevOps" approach was developed to address these challenges by merging development and operations teams, enabling faster adaptation to updates and development changes.
The DevOps approach symbolizes continuous improvement and collaboration between teams, leading to smoother and more consistent deployments.
The DevOps life cycle consists of several phases, including planning, version control, build, test, deployment, and monitoring.
In the planning phase, a plan is created, and the coding process begins, with different versions of the code stored in repositories using tools like Git and Merge.
In the build stage, the code is made executable using tools such as Maven and Gradle.
The testing phase involves manual and automated testing using tools like Selenium.
The deployment phase employs tools like Ansible, Docker, and Kubernetes to automate the process of deploying code to working environments.
The monitoring phase continuously monitors the product and gathers feedback, which is then integrated back into the planning phase.
Tools like Nagios and Jenkins are used to automate the phases of the DevOps life cycle.
Many tech giants, including Amazon, Netflix, Walmart, Facebook, and Adobe, have implemented the DevOps approach to streamline software development processes and improve efficiency.
