A DevOps engineer is an IT professional who oversees code releases and deployments with software developers, system operators (SysOps), and other production IT workers. The position requires someone with necessary hard and soft abilities to bridge the conventional gaps between software development, QA, testing, and IT operations teams and build a collaborative, holistic atmosphere.
A DevOps engineer’s roles and responsibilities
A DevOps engineer must be familiar with the IT architecture that supports software code in dedicated, multi-tenant, or hybrid cloud settings. They may be required to provision resources, choose an acceptable deployment architecture, direct testing protocols to validate each release, and monitor performance following release. Tasks may involve preparing test data, analyzing results, debugging problems, and communicating issues to software developers.
The DevOps methodology for software development aims for frequent, incremental changes to code versions. Which necessitates frequent deployment and testing regimes. Although DevOps engineers rarely write code from scratch. They must understand the fundamentals of programming languages and be conversant with the development tools needed to produce new code or update old code. A DevOps engineer collaborates with development staff to complete the coding and scripting required to connect various application elements, such as APIs, libraries, and software development kits (SDKs), as well as integrate other components, such as SQL data management or messaging tools, that DevOps teams require to run the software release on OSes and production infrastructure.
They in particular, focuses on automation and maintenance in the live environment. Therefore employment titles that emphasize automation and maintenance of software products, systems, and services are widespread. A DevOps engineer, for example, would automate and maintain a big data build pipeline; provide on-call service to ensure system uptime; and so on. Develop or procure application and system management tools that reduce manual effort; implement automated management features such as performance monitoring, diagnostics, and failover and availability capabilities; and assess risks for all changes while ensuring high availability in the environment.
DevOps knowledge, training, and certification
The function of DevOps engineer does not have a single career path; professionals come from a variety of backgrounds. A DevOps engineer, for example, may begin as a software developer who supervises elements of IT operations. A DevOps engineer, on the other hand, may advance from a system administrator post due to their expertise of coding, scripting, integration, and testing. Depending on the organization and its technological demands, there may be some overlap between DevOps and SysOps engineer job descriptions. But it is the DevOps engineer whose responsibilities include modifying business processes as needed to solve organizational problems and improve business outcomes.
Despite the broad and varied scope of DevOps roles, there are some common skills and traits for job candidates to emphasize when looking for work, such as: a comprehensive background in OS administration, such as Linux and Windows; strong experience with a variety of automation and configuration management tools, such as traditional scripts, as well as more specific tools such as Puppet and Chef;
a solid understanding of coding and scripting with common languages such as PHP, Python, Perl, and Ruby; knowledge of at least one major coding language such as C++ or Java; the ability to identify, assess, and integrate various open source technologies and cloud services; and a strong IT hardware and operations background with hands-on experience in server, storage, and network device installation, provisioning, and monitoring. This is typically supplemented by knowledge of IT best practices for fault-tolerant, high-availability operations; supportive and collaborative management abilities in a team environment, as well as proven customer-facing management skills; strong knowledge of virtualization technologies, such as VMware vSphere for VMs. As well as expertise with container technologies, such as Docker and Kubernetes; and proven experience with CI/CD tools, such as Microsoft GitHub, Atlassan, and Jenkins.
Some firms recruiting DevOps engineers may have extra employment criteria, such as a security clearance. Therefore it’s critical to read the job advertisement for each function or employer. DevOps roles often have minimal formal education and training requirements. Which typically comprise a Bachelor’s Degree in computer science or engineering. As well as an AWS or Azure certification in public cloud services. According to hiring managers in DevOps, there is no practical substitute for hands-on experience.
Salary of a DevOps engineer
According to the DICE 2019 Tech Compensation Report, the average yearly salary for a DevOps engineer in 2019 is more than $110,000 (USD). The actual wage can vary depending on the extent of the actual work tasks. As well as the position’s geographic location. DevOps salaries are currently higher than those for traditional IT professions. Such as software engineer or developer, hardware or systems engineer, and project manager. However, as DevOps becomes more of a fixture in the modern company. The significant annual increase in DevOps pay has begun to decelerate and level off.
