The skills and approaches you develop as a DevOps engineer are critical to ensuring your organization can efficiently deliver high-quality software solutions that meet evolving customer expectations and competitive demands. “Building a practice around service reliability and chaos engineering, for Site Reliability Engineering (SRE) teams in particular, can help to establish more resiliency within the applications they support,” Wadhwani says.
Once a bachelor’s degree has been earned in computer engineering, software engineering, information technology, or computer science, one can pursue employment as a DevOps engineer. DevOps engineers draw on knowledge of project management practices, automated processes, reporting, security, and overall IT infrastructure in their daily tasks. Learn to design and deploy infrastructure as code, build and monitor CI/CD pipelines for different deployment strategies, and deploy scalable microservices using Kubernetes. At the end of the program, you’ll combine your new skills by completing a capstone project.
Infrastructure Automation
- A DevOps engineer is a professional with skills in both the development and operation side of software engineering.
- SRE focuses on maintaining system reliability and uptime by applying software engineering principles to operations tasks.
- They work with developers to ensure that code is efficiently built, tested, and deployed, while also maintaining the underlying infrastructure to keep applications running smoothly.
- Explore several software engineer degree pathways to determine which might be right for you.
- Not only that, it’s also great for scripting and automation, as well as data analysis and processing.
These subjects equip you with a strong foundation in programming, data structures, algorithms, and DevOps security – all crucial for a DevOps position. A DevOps Engineer must be adept at working with different teams, using written and verbal communication to boost team cohesion. The role requires a deep understanding of technical details and clear communication – it can be the difference between a project’s success or failure.
The field of computer science is more broad, including topics such as computer theory and computer hardware design, which focuses on understanding how each component connects to and interacts with another. Nowadays, security isn’t just tacked on at the end; it’s woven throughout the entire DevOps workflow, often called DevSecOps. DevOps engineers play a key role in building security measures right into the development process from the start. Instead of setting up IT infrastructure manually, DevOps engineers define and manage it using code – a practice called Infrastructure as Code (IaC).
DevOps Engineering is a great career to get into right now, with high become a devops engineer demand (almost a half million jobs in the US alone!), a great salary, and interesting topics to learn. Also, depending on the time that you read this, there may be new specific A.I. Tools for your role, so have a quick Google search and see if there anything that can help, and play around with it. By learning to use these tools, you can increase your output and perform repeatable tasks in minutes vs hours or days.
Academic Degrees
The knowledge of programming languages, coding processes, software development, and IT operations needed to work as a DevOps engineer is most often obtained by completing a four-year degree program.
