DevOps engineers are more in demand than ever. Many organizations are moving towards DevOps — an ethos that integrates software developers and IT professionals who manage production operations for a smoother and more productive workflow.
DevOps engineers bridge the gap between software development teams and IT operations. Thanks to constant communications and agile work policies, organizations with DevOps can create and deploy more code, faster and more securely than when using traditional methodologies. But that's easier said than done; the variety of skills required, and the recent and evolving nature of the role make serving as a DevOps engineer time-consuming and onerous.
What does a DevOps engineer do?
In simple terms, a DevOps engineer is an IT professional who understands the Software Development Life Cy-cle (SDLC) and can use engineering tools and processes to solve operational challenges. The engineer must balance a number of different functions, including coding, integration, and testing, with the goal of improving collaboration and speeding up the development process.
These professionals are typically senior developers or system administrators skilled in in business, organization, configuration, automation, operations, and leadership. DevOps requires frequent and incremental changes to code versions to allow frequent testing and implementation. DevOps engineers must connect the different coding elements with libraries and SDKs and integrate different SQL data-management components or messaging tools to run software releases on the operating system and production infrastructure.
These are the fundamental processes and tools that a DevOps engineer must be familiar with:
- Automation (Jenkins, Bamboo): To simplify processes and customize the delivery pipeline.
- Code Management (Git): To track development progress, view version history, and test different paths before unifying into a final product.
- Containers (Docker, Kubernetes): The versatility that containers provide in software deployment is key in DevOps.
- Configuration management (Puppet Enterprise, Ansible, Chef): These tools allow you to configure and manage infrastruc-ture and automate deployment.
- Monitoring (Nagios, Raygun): These help the DevOps team monitor infrastructure to quickly fix problems.
- Project Management (Jira, Trello): Widely used in other areas, they make it easier for work to get done and projects to reach completion.
- Cloud platforms (AWS, Azure, GCP): In addition to providing savings and greater agility in almost all industries, here is where the IT world is moving with greater constancy. Lack of familiarity with these platforms could cripple a DevOps operation.
DevOps Engineer: One of the most in-demand professions in the world
Demand is high for these jobs as more companies turn to DevOps practices to deliver security and software updates more quickly, both internally and to customers. We also see a shortage of those with the right skills in development and operations across the technology sector. The number of job vacancies mentioning DevOps increased from less than 1% in 2012 to more than 24% in 2017, according to Indeed.
DevOps Engineer was named the third most in-demand tech jobs in a 2016 report, and the second hardest to fill.
Benefits of DevOps Engineers for companies
Speed is definitely one of the most desirable benefits of DevOps, as it allows companies to put the pedal to the metal when it comes to functionality. A more quickly produced version of the software means that companies can take advantage of the value of the product's features. Everyone knows that product testing, as necessary as it may be, is also time-consuming. With DevOps, a business can accelerate delivery and change process through integration and automated testing. Not only that, but there is also a full team of developers who can keep a close eye on a product throughout its life cycle. This constant vigilance reduces the time it usually takes for teams to locate and correct errors and faults.
The good thing about a competitive market is that quality will always outperform quantity. That is why the quality of the software is worth its proverbial weight in gold. Quality and reliability are two things that DevOps can bring. DevOps helps optimize the way a company conducts its software testing; rather than making testing a part of the (SDLC), DevOps elevates it to a crucial, overarching component across the entire SDLC. On the other hand, reliability allows a system to operate continuously within its environmental constraints, which in turn promotes the overall connectivity of services necessary for the smooth operation of a business.
The point is that it's not that people didn't realize that consolidating development, operations, and QA teams would add more value to a business before the DevOps culture took off. However, even then, older software methodologies were missing an important element: collaboration. What DevOps did was bring interdepartmental collaboration to the forefront and change the way those units interacted with each other. We all know that DevOps is an improvement over lean and agile software methodologies, so it's not surprising that DevOps naturally highlights operations as well. In a DevOps environment, teams don't exist on their own separate plane, and department-specific goals are lost. The great thing about collaboration under a DevOps model is that the focus shifts from team efficiency to overall combined performance because everyone shares responsibility for the end product. In addition, the increased interaction between development, operations and QA teams provides another immeasurable advantage in the form of technical updates.
Security is a great thing when it comes to IT. It doesn't matter that your product line is running fast if its data protection is compromised. But here's some good news: in addition to all the other benefits that DevOps can offer businesses, it can also help strengthen security. It does this by adding security as a separate element to the development and operations components and thereby transforming itself into DevSecOps. With DevSecOps, responsibility for security does not lie with one team, but everyone is responsible for security and defense. DevSecOps not only helps reduce costs, but it also helps you detect and address security issues early on.
