What is a DevOps engineer and what do they do?

Give your career the edge it deserves, start preparing now and get a step closer to your dream DevOps engineer job role. Experienced DevOps engineers with a passion for innovation and entrepreneurship may choose to start their own consulting firms or technology startups. Entrepreneurial opportunities abound in areas such as DevOps consulting, cloud migration services, DevOps tool development, and software-as-a-service (SaaS) solutions catering to DevOps needs. Launching a startup allows DevOps engineers to pursue their creative vision, solve complex problems, and make a significant impact on the industry.

They largely work to automate, maintain and manage development applications and processes. Monitoring and logging solutions are essential for ensuring the reliability, performance, and security of software applications in production environments. These tools facilitate proactive monitoring, troubleshooting, and optimization of system performance and availability. As the world of business becomes increasingly reliant on technology, the role of a DevOps engineer is becoming more and more important. Companies are looking for individuals who can help them to streamline their operations and make the most of their IT infrastructure.

DevOps Engineer Certifications + Programs

DevOps engineers specialize in development and operations processes to coordinate efficient product development for a company. DevOps engineers also oversee the activities and needs of a software product’s creation from planning to deployment. Typically, the development, testing, and support departments were used to working in silos, creating process gaps and conflict in duties as different people managed these functions. Such barriers were the significant causes of misunderstandings, miscommunications, and conflict in prioritization and were proven detrimental to productivity, resulting in customer dissatisfaction. DevOps’ evolution as an approach and a DevOps engineer job profile has tried to close these gaps to a great extent.

Familiarity with several programming languages enables a DevOps engineer to more clearly identify opportunities to automate the development process. Popular languages, such as Python, Java, and JavaScript, are all good candidates for DevOps engineers to know. DevOps engineers are responsible for infrastructure provisioning, infrastructure management, process automation, system administration, and security for an entire organization. A DevOps engineer is an IT professional that that manages an organization’s developer operations (DevOps), which includes all the practices and tools that the organization uses to create and manage software.

What are the duties and responsibilities of a DevOps Engineer?

A DevOps Engineer ensures all this happens smoothly and consistently throughout the development life cycle. The future of DevOps engineering looks bright, devops engineer training but it isn’t something anyone can just jump into. DevOps engineering is rewarding, challenging, and offers an opportunity to learn and evolve.

A DevOps culture is where teams embrace new ways of working that involve greater collaboration and communication. Adopting DevOps first requires a commitment to evaluating and possibly changing or removing any teams, tools, or processes your organization currently uses. It means building the necessary infrastructure to give teams the autonomy to build, deploy, and manage their products without having to rely too heavily on external teams. Teams entrenched in siloed ways of working can struggle with, or even be resistant to, overhauling team structures to embrace DevOps practices. Everyone on a DevOps team must understand the entire value stream — from ideation, to development, to the end user experience.

They might have to provision resources, select an appropriate deployment model, direct testing to validate each release and monitor performance after release. Tasks might include test data preparation, results analysis, problem troubleshooting and issue communication back to the software developers. Continuous delivery expands upon continuous integration by automatically deploying code changes to a testing/production environment. It follows a continuous delivery pipeline, where automated builds, tests, and deployments are orchestrated as one release workflow. Configuration management tools enable DevOps engineers to automate the provisioning, configuration, and management of infrastructure resources and application environments. Examples of configuration management tools include Ansible, Puppet, Chef, and SaltStack.

CI/CD introduces ongoing automation and continuous monitoring throughout the lifecycle of apps, from integration and testing phases to delivery and deployment. This all occurred while IT worked on a subsequent patch or iteration of the product, which they had no knowledge or input about. When an update arrived from the development team, this slow and painful cycle simply repeated itself, handing off the new code to IT and letting Operations deal with deployment and its aftermath.

What Is a DevOps engineer?

This includes the practices involved in design, implementation, configuration, deployment, and maintenance of all IT infrastructure that supports an organization’s services. Continuous integration (CI) allows multiple developers to contribute to a single shared repository. When code changes are merged, automated tests are run to ensure correctness before integration. Merging and testing code often help development teams gain reassurance in the quality and predictability of code once deployed. DevOps engineers are usually part of a product team or designated DevOps team within a company, and may perform project management duties within their team. They frequently collaborate with software developers, software engineers, system operators and other IT professionals to accomplish their work.

The DevOps cultural shift may require executives and developers, for example, to hone their listening skills in ways they never had before. Say a product was in the final stages of its development, with great design and features that were easy to use. But, as the teams were about to pop the bubbly, they discovered a security vulnerability in the database. DevOps refers to a way of developing software that keeps everything running smoothly across each stage of development. Before DevOps was introduced in 2009, dev teams usually built each part of an application independently. To become a DevOps engineer typically calls for a tertiary qualification in computer science or a related area of study.

Tools and Programs DevOps Engineers Use

Creating alerts or performing real-time analysis of this data also helps organizations more proactively monitor their services. Build more effective teams under a DevOps cultural model, which emphasizes values such as ownership and accountability. Developers and operations teams collaborate closely, share many responsibilities, and combine their workflows.

However, these roles are less important (if not obsolete) with the use of strategies like automated testing and dark deployments. This person must possess a wide ranging skill set that spans both development and operations, but also the interpersonal skills to bridge divides between siloed teams. Developers and system administrators use code to automate operating system and host configuration, operational tasks, and more. It frees developers and systems administrators from manually configuring operating systems, system applications, or server software. While DevOps engineers don’t wear a software developer hat, familiarity with varying programming languages is beneficial, if not, often, required.
