DevOps has become a ubiquitous term in the IT industry, with the demand for talented DevOps engineers skyrocketing over the past few years, experiencing growth between 35% and 45%. Due to the multifaceted skill set required for the job, the role of DevOps engineer is considered challenging. It is no wonder that DevOps is increasingly becoming a popular approach in the field of IT. If a career as a DevOps engineer appeals to you, then you are on the right track.

What is DevOps?

Initially coined by independent IT consultant Patrick Debois, “DevOps” has experienced significant growth and development as a discipline. The collaboration of developers and operations staff has given birth to DevOps Engineers, who have been able to cut down delivery times considerably. Given the constraints of Agile, the demand for DevOps Engineers is on the rise, resulting in a bottleneck in the agile software delivery process. Operations teams are struggling to keep up with the pace of development teams, who are pushing new changes in each sprint which raise concerns about application stability and security.

In recent years, DevOps Engineers have played a crucial role in bringing together developers and operations teams, facilitating collaborative workflows utilizing various techniques and technologies. By continuously monitoring, infrastructure agility can be optimized, and application management and security can be streamlined.

DevOps Model: Phases and their Significance

1. Continuous Growth

Continuous Development marks the first phase of the DevOps lifecycle, covering the entire process of creating a software product from inception. DevOps Engineers begin by envisioning the final product and devising a plan accordingly. Developers then proceed to write and modify code, which is typically managed through source code management systems such as Subversion (SVN), Git, Jira, and CVS, which are popular in the industry.

2. Continuous Integration

Effortless transitioning from the Continuous Development phase to the Continuous Integration phase is crucial. Continuous Integration comprises numerous activities such as comprehending project requirements provided by the customer and preparing test execution for the testing stage. Regular source code changes are made, generally on a weekly basis. The Continuous Integration phase is widely regarded as the ‘heart’ of the DevOps lifecycle as potential code issues are likely to be pinpointed during this phase.

3. Continuous Testing

During the Continuous Testing phase, the code is continuously scrutinized for any flaws or vulnerabilities. The compatibility of the product with client requirements is determined during this phase, and the application’s usability is evaluated using a set of standard QA methods. Continuous testing is facilitated by automated testing solutions, such as open-source tools like Selenium or state-of-the-art test management systems like QARA Enterprise and TestNG. DevOps Engineers in QA teams can take advantage of these tools to maximize their time and resources by running multiple tests simultaneously.

4. Continuous Deployment

Continuous Deployment is the fourth phase of the DevOps lifecycle that involves delivering code without affecting the product or website’s features. Verifying the correct installation of the code on all servers is crucial at this stage. Ensuring seamless and error-free product deployment is of utmost importance.

5. Continuous Monitoring

Continuous Monitoring is the fifth and final stage of the DevOps lifecycle. This phase comprises the collection and analysis of data related to the application to identify issues and overall trends. Once the software is launched, it can be continually monitored and adjusted for optimal performance as part of an ongoing operational process.

Essential Skills and Advice: How to Become a DevOps Engineer

The subsequent paragraphs will cover the top eight skills that an aspiring DevOps Engineer must possess.

Collaboration and Information Sharing

DevOps Engineers must possess effective communication and collaboration skills for successful DevOps process implementation. These two factors play a crucial role in establishing a cross-functional DevOps culture, bridging the gap between Development and Operations teams, and ensuring alignment of team goals with business objectives. Hiring remote DevOps Engineers with such skills can be beneficial for the team’s productivity and performance.

Interpersonal Skills

DevOps Engineers must possess more than just coding proficiency and process automation abilities. They must possess interpersonal skills, motivation, flexibility, and a passion for learning. Strong communication skills and the ability to deliver results are also critical for success in this role.

For a successful DevOps transformation, it is vital that all parties involved understand the significance of collaboration. This involves meaningful dialogue between stakeholders, considering the company’s goals, conducting a fair assessment, and identifying areas for improvement.

Utilization of Tools

The effectiveness of DevOps is heavily reliant on the tools utilized throughout the process. With numerous tools associated with DevOps, it can be challenging to be well-versed in all of them. Nevertheless, given the significance of DevOps success, it is important to explore them extensively.

Ensuring Safety and Security

DevOps implementations often display a correlation between risk and delivery rate. The conventional approach to security may prove ineffectual in the long run or on its own. In this regard, DevSecOps stands out as it integrates security into the Software Development Lifecycle (SDLC) right from the start.

Hence, to attain success as a DevOps Engineer, DevSecOps competencies are indispensable.

Robotics and Automation Proficiency

To be recognized as a DevOps Engineer, a thorough understanding of automation is crucial as it serves as the backbone of the DevOps approach. A DevOps Engineer should possess knowledge of automating all stages of the DevOps pipeline, including continuous integration/continuous delivery cycles, application performance monitoring, infrastructure, and configurations.

Proficiency in coding and scripting skills is inherently linked to DevOps automation savvy.

The Craft of Programming

To achieve success as a DevOps Engineer, it is crucial to have a strong grasp of both programming and scripting.
The programming language arena is vast and encompasses Python, Ruby, Java, JavaScript, PHP, Bash, Shell, and Node.js, which is particularly prolific. Node.js is an extensively utilized scripting environment and programming language.

Competencies Assessment

Testing is a vital aspect of DevOps’ overall success. The DevOps automation pipeline requires tests that can consistently conclude successfully.

This is crucial for automated test execution, which serves as the cornerstone of continuous testing.

Proficiency in Cloud Skills

It is evident that cloud computing and DevOps are inherently intertwined and mutually beneficial. DevOps serves as the driving force for the process, while the cloud delivers the requisite infrastructure for software development, testing, and deployment.

The cloud delivers the critical toolchain for Continuous Integration/Continuous Deployment and resource monitoring, enabling the automation of DevOps processes.
