DevOps is an essential part of modern software development. The term DevOps refers to the integration of software development (Dev) and IT operations (Ops) with the goal of creating a more agile, efficient, and reliable software development process. DevOps engineers are critical to this process and play a vital role in ensuring that the DevOps pipeline is optimized for maximum efficiency. In a Grand View Research, Inc. study, DevOps Engineers ranked No. 4 on Glassdoor's list of the 50 Best Jobs in the USA in 2022. By 2025, the global DevOps market is expected to reach US$12.85 billion, growing at a compound annual rate of 18.60%. 

DevOps has seen a substantial increase in investment from companies in recent years. It is common for users to leverage tools like Chef, Docker, and Puppet. Due to this, there is an increasing need for qualified DevOps engineers.

What does a DevOps engineer do?

DevOps engineers are involved in coding and scripting for various software development kit components, including APIs.

A DevOps engineer is responsible for bridging the gap between development and operations teams by automating the software development lifecycle and streamlining software delivery. They create a culture of collaboration and continuous improvement to help organizations achieve faster time-to-market, improved product quality, and more reliable software delivery.

Automation tools, containerization tools, cloud computing platforms, and monitoring and logging tools are among the tools and technologies that DevOps engineers typically use. The tools automate the software development process, integrate and deploy code changes, and monitor and troubleshoot applications.

Working effectively with cross-functional teams requires strong communication, collaboration, and technical skills. Building and maintaining solid relationships with developers, operations, and other stakeholders is their responsibility.

A DevOps engineer is critical to software development, ensuring that software is delivered quickly, reliably, and with high qualifications.

The ability to use source control systems

Source control systems are essential tools for facilitating collaboration between developers. As DevOps brings together individuals from various sectors, it is critical for DevOps engineers to have expertise in source control or version control systems. These systems enable tracking changes in an application and maintaining different versions of the application. Becoming proficient in version control systems requires effort, as each tool has advantages and disadvantages.

Understanding the importance of version control systems in the DevOps culture is crucial. For example, they prevent dependency issues in modern containerized applications, directly impact DevOps performance, and help build more reliable applications.

Therefore, every DevOps engineer should have experience working with at least one of the following tools: Git, CVS, SVN, or Mercurial. By mastering these tools, DevOps engineers can streamline collaboration and contribute to the successful delivery of high-quality software products.

Networking and security principles

Almost everyone needs a strong knowledge of security, particularly DevelOps coding skills. DevOps skills include code analysis, change management, threat research, security courses, and vulnerability assessments.DevOps engineers need a strong understanding of networking and security principles, such as TCP/IP, DNS, firewalls, and VPNs. Furthermore, they should be knowledgeable about privacy and security regulations, such as HIPAA and PCI DSS.

Collaboration and communication skills

As DevOps engineers work closely with developers, operations teams, and other stakeholders, they must possess excellent communication and collaboration skills. Working in a team, communicating complex technical concepts, and bridging departmental gaps are all skills they should possess.

Problem-solving skills

DevOps engineers must be capable of troubleshooting complex technical issues and developing solutions quickly. As well as being able to think critically and creatively when faced with challenges, they should also be able to come up with efficient and effective solutions.

Final thoughts

Becoming a DevOps engineer requires a wide range of skills, including understanding the SDLC, knowledge of automation tools, cloud computing skills, networking and security, collaboration and communication skills, and problem-solving skills. Any organization looking to streamline operations and improve software development processes can benefit from these skills. By mastering these essential skills and continually developing new ones, DevOps engineers can ensure that their teams are working efficiently and effectively while delivering value to their customers. With the right skills and mindset, DevOps engineers can truly make a difference in today's rapidly evolving technology landscape.

DevOps always prioritizes the customer, recognizing that delivering a product that satisfies their needs is paramount. To achieve this, DevOps engineers must have a comprehensive understanding of the big picture and a clear understanding of the customer's requirements. However, DevOps engineers often lack this ability, many of whom come from a software development background without specific DevOps training. Consequently, there is a significant gap between software development and DevOps engineering. To successfully bridge this gap, it is crucial for DevOps engineers to appreciate the broader context and focus on satisfying the customer. At the same time, a software developer is primarily responsible for coding what has been requested. By understanding this distinction, a DevOps engineer can deliver high-quality products that meet customer expectations.
