What is DevOps?
DevOps is considered to be a combination of developers and operations.
DevOps has several stages, and a set of tools for automating each stage.
Let's run the life cycle of DevOps.
Developers first develop plans to decide which modules and algorithms to use. Then, code the program later and add a star to the repository like Git. The repository holds the original code and the code version, which is called version control. Then get the code and make it executable during the build phase. Tools such as Gradle and Maven can solve this problem. Before deployment, the product will be tested using popular automated testing tools (such as selenium) to check for errors. After product testing is completed, DevOps engineers will deploy it. Then the deployment products are continuously configured to the desired state. Ansible, Puppet and Docker are some tools that automate these stages.
The work requirements of each product are continuously monitored. Nagios tools can automatically complete this stage. Then feed back the feedback to the planning stage. The core of the DeOps life cycle is the integration phase. Tools such as Jenkins are responsible for sending code for building and testing. If the code passes the test, send it for deployment. This is called continuous integration.
Why is DevOps certification important?
The DevOps certification is an approved certificate that demonstrates the specific competitive skills and topics required to become a successful DevOps professional. Obtained through various assessments,
education courses or performance reviews, proving that they meet strict standards.
DevOps positions have always been one of the highest paid positions, so getting a certificate can increase your chances of getting a good job. Certification also prepares you for team work consisting of cross-functional team members, including quality assurance, developers, operations engineers, and business analysts.
