What is a DevOps engineer?
A DevOps engineer is someone skilled in both IT development and operations. They bring process improvements, tools, and methodologies to the software development lifecycle to increase efficiency and get software from concept to release quickly.
What does a DevOps engineer do?
DevOps engineers reduce complexity, closing the gap between actions needed to quickly change an application, and the tasks that maintain its reliability.
Development teams and IT operations teams can have different skills and different goals. Developers want to introduce new features to an application, while operations teams want to preserve the stability of an application once it is released.
DevOps is all about the unification and automation of processes, and DevOps engineers are instrumental in combining code, application maintenance, and application management. All of these tasks rely on understanding not only development life cycles, but DevOps culture, and its philosophy, practices, and tools.
Within an agile environment, developers, system administrators, and programmers can be siloed, working on the same product but not sharing information necessary to ensure value to the user.
Some organizations may hire professionals to "perform DevOps" within their workflows, but because successful DevOps adoption depends on changes to culture and process, this may just deepen the disconnect between developers and operational teams.
DevOps essentials
DevOps engineers build new skills on top of their current experience. Tasks like data management and library updates for new product releases combine with needs for leadership and collaboration across teams. It is important for DevOps engineers to understand the fundamentals of application development and delivery.
Continuous Integration/Continuous Delivery (CI/CD)
You and your teams can build and test changes, add to repositories, and deploy updates quickly and efficiently.
Security
DevOps processes such as CI/CD security can be used to safeguard code pipelines with automated checks and testing to prevent vulnerabilities in software delivery.
