What does DevOps mean?
DevOps is a workflow strategy that emphasizes collaboration between development and operations at a company, usually related to software development. The concept of DevOps is related to agile methodology, focusing on optimizing success by integrating the work of software developers and IT professionals. Successful DevOps management has several key goals:
- Faster security updates and software patches
- Reliable IT troubleshooting techniques
- Consistent internal and external methods
- Improved automation
- Reduced glitches and software failures
What is a DevOps engineer?
DevOps engineers manage the operations of software development, implementing engineering tools and knowledge of the software development process to streamline software updates and creation. They are usually senior-level technology professionals who lead and coordinate different teams that create or use company software. They oversee code updates and may take on different roles as they help colleagues design, develop, test and release software to consumers. DevOps engineers have a strong understanding of the agile methodology and industry standards alongside the specific networks and processes within their company.
What does a DevOps engineer do?
Because DevOps engineers oversee operations in multiple departments, they have a wide range of roles and responsibilities that they fulfil on any given day. To guide the engineering, re-engineering and implementation of software tools and code updates, DevOps engineers work in these key areas:
DevOps engineers are instrumental in creating a strategic plan for implementing goals. They assess risk, analyze costs and benefits, set operational expectations and forecast future projects to create a timeline. They consult on leadership decisions from a workflow management perspective then develop a plan for carrying out those goals across departments.
Writing and editing code
Most DevOps engineers spend some time writing and improving code. They review software scripts and look for ways to improve automation and resolve user interface issues. Some DevOps engineers fully delegate coding to software developers, but they need to understand coding languages to provide useful advice and accurately consult on workflow issues.
DevOps engineers participate in server administration to monitor and improve the networks and servers that host company software. They create user accounts, update permissions and make sure server information is regularly and securely backed up. They review system logs to identify glitches and possible human error. DevOps engineers responsible for server administration set standard procedures for IT professionals and software developers to follow when making changes or troubleshooting.
Tracking staff communication
DevOps engineers help tech support understand software developments and manage feedback from team members to improve project development. They drive how workflow evolves, updating team members and giving them clear channels of communication. Tracking how team members communicate through back-end software tools allows DevOps engineers to identify solutions for workflow issues.
After identifying an issue or an opportunity for improved efficiency, DevOps engineers create prototypes of software tools then present them to a team of developers for implementation. They explain how systems should be configured and identify the problems code updates should address.
Evaluating and coaching
In addition to managing systems communications, DevOps engineers evaluate team performance and create development plans to improve their communication skills. They identify the skill gaps on their staff and create intuitive systems for training staff to fill those gaps.
Making sure company data is safe and secure is one of the key aspects of DevOps work. They integrate security measures with software processes and ensure that updates do not create any vulnerabilities. Because DevOps engineers use so much automation in their daily work, keeping information secure by identifying possible breaches and addressing them is especially important.
Testing system performance
DevOps engineers run tests on the effectiveness and efficiency of various software tools. This is also known as quality assurance or QA software testing. They assess how well each programming method works in the context of its task. Testing helps DevOps engineers identify infrastructure flaws and draft code to solve a problem or alert team members to start working on a solution.
