How to Hire a DevOps Engineer

Due to its encompassing definition, it is understandable that DevOps may appear puzzling at the outset. Employing a DevOps engineer may appear counterproductive initially; however, once you gain insight into the advantages, you will understand why it is a worthwhile investment.

DevOps is a concept that encompasses a broad range of activities which involve collaboration between operations and development personnel throughout the entire lifecycle of a service. This encompasses all stages of the process, from the initial brainstorming and sketching of ideas, to the actual production of the service.

Software development involves a variety of primary activities such as coding, implementation, testing and bug fixing. In contrast, the focus of operations is the maintenance of hardware and software that is used to run the program, ensuring that the appropriate computational resources are made accessible.

It is evident that, although the two teams may be using the same technology, there is a lack of effective communication between them. DevOps seeks to bridge this gap by bringing these traditionally distinct branches of engineering together and fostering improved communication between them.

One of the primary objectives of DevOps is to actively promote automation and monitoring at all stages of software development, from integration and testing, through to releasing and deployment, and even infrastructure management. This approach is designed to reduce the amount of time and effort required to bring a product to completion, as well as increase the efficiency of the process as a whole.

Having a cohesive team can have far-reaching benefits for business. According to a study conducted by automation tool vendor Puppet, businesses that use DevOps strategies are able to deliver code up to 30 times more frequently than those who do not, and experience 50% fewer failed deployments. This highlights the importance of having a united team in order to ensure operational efficiency.

It is clear from the evidence that your team has the potential to increase their productivity, efficiency and speed of delivery if you choose to bring a DevOps engineer onboard. Working collaboratively in this way not only accelerates the completion of program, but also increases their value and encourages the development of innovative ideas.

DevOps Engineer vs. Build and Release Engineer

The Functions of a DevOps Engineer

With the continuous evolution of the job market, it can be difficult to define the specific responsibilities of a DevOps engineer. Typically, these professionals come from a range of IT-related backgrounds, meaning that their job roles are not exclusive to one another.

DevOps Engineers strive to improve the software development process by combining the key stages (such as design, testing, deployment and integration) into one single, efficient operation. Their key roles involve ensuring that businesses have the necessary cloud infrastructures in place.

The primary duties of a DevOps engineer are:

  • Create and organise the required infrastructure and development tools.
  • Develop better methods of automation and release management.
  • Verify the other team members’ work by inspecting their code.
  • Find technical issues and provide answers.
  • Arrange software development initiatives in advance.
  • Errors may be reduced through testing code, procedures, and deployments.
  • Performs a gap analysis and makes recommendations to improve performance.

Why You Need a DevOps Professional

While the data speaks for itself, let’s take a closer look at why you may want to bring on a DevOps engineer.

Consistency and Progress

When the development and operations teams are separated, a new standard of evaluation is used in order to assess performance. Developers are praised when they meet the specified target with regards to the number of updates and new features they are able to provide to customers. On the other hand, the operations staff are evaluated according to how well the system handles the application and whether it remains functional.

The employment of a DevOps Engineer encourages the whole team to work together to not only improve the system, but to also ensure it is properly maintained. Through the use of Continuous Integration, Automated Deployments and Test-Driven Methodologies, the codebase can be kept efficient and up-to-date due to the close collaboration between all team members working on the same code.

Effectiveness and the Quality of the Service Provided to Customers Are Enhanced

The ultimate aim of any software development or maintenance project should be to produce a highly refined product which customers will find enjoyable to use. By adopting DevOps practices, you can reduce the number of errors and enhance the performance of your program, resulting in a more positive user experience.

Implementing DevOps practices can have a significant positive impact on your clients. Continuous software delivery, faster issue response and increased staff engagement are all benefits that your clients can experience, leading to a boost in sales and improved customer satisfaction. This can help your business to stand out from the competition and ensure that your customers remain delighted with the services they receive.

It is important to remember that team productivity has increased due to the reduced amount of time wasted waiting for information from other teams regarding an application or system. Not only does this result in a financial loss for the employer, having to pay for workers who are not working, but it also causes unnecessary frustration for the employees as they are unable to use their time effectively.

Increase the Performance of Your IT Department

If you are looking to bolster your team, a DevOps engineer could be the ideal addition. Such an individual is highly versatile and can assist with a variety of tasks, including standardizing procedures and practices, ensuring that software runs effectively, and identifying any mistakes in the code of other members of the team.

Hiring a remote DevOps engineer has the potential to be highly beneficial for any organization, offering cost savings and access to the best talent available globally. If you are seeking to recruit an engineer, but are hampered by local recruitment options, why not explore the possibility of sourcing from a country where the cost of living is lower? Doing so could open up a world of opportunity for your IT team.

Top Interview Topics for a DevOps Engineer

It is clear that DevOps offers many advantages, however hiring a DevOps engineer can be a difficult task due to the absence of a set route to this role. Furthermore, the high level of expertise demanded by this role means that the number of extremely qualified DevOps engineers is limited.

So, before you employ a DevOps engineer, let’s have a look at some of the questions you may ask to verify their expertise.

How does DevOps differ from Agile?

Nevertheless, Agile is predominantly focused on production approaches, such as those used in software engineering. Agile-created software, meanwhile, might be constrained to certain contexts such as testing. However, with the aid of DevOps practices, your team will be able to deploy the software to the production environment with greater ease and security.

In contrast to Agile’s focus on code quality alone, DevOps also ensures that software can be reliably deployed.

Please discuss the most well-known DevOps tools and the ones you have worked with.

There are many different DevOps tools available, but some of the more common ones are:

  • Git, a software for managing versions of files,
  • Jenkins, a continuous integration technology
  • Selenium is a tool for continuous testing.
  • Puppet, Chef, and Ansible are configuration management and deployment tools.
  • Nagios is a tool for continuous monitoring.
  • Docker, a tool for containerization

It is unsurprising that many of the developments driving DevOps strategies relate to automation – the improved automation will mean less room for error and more time for engineers to focus on the essential aspects of their work.

Therefore, before hiring a DevOps engineer, ensure that they are fluent in all or the majority of these common technologies.

Show me how everything fits together

Organizations are increasingly in need of DevOps Engineers who have both an appreciation of the wider implications of their role, as well as an attention to detail. In order to be successful in their role, these Engineers must understand how each individual element of their work contributes to the holistic goal. This will allow them to cooperate effectively with both the development and operational sides of the business.

By posing this question, we can ascertain that everyone is aware of their duties and the resources available to them. As suggested by Edureka, this is a fundamental process; however, it is important to note that the details of this procedure may differ between companies, depending on their individual aims and objectives.

  1. Programmers create code that is then stored in a Git repository and controlled with the use of Version Control System (VCS) tools.
  2. All code modifications made by the development team are pushed to a central repository and committed by each member of the team.
  3. Using the Git plugin, Jenkins retrieves the source code from the repository and builds it using several tools, including Maven.
  4. Testing environments can be deployed and provisioned through the use of Puppet or an alternative configuration management tool. Once this is complete, Jenkins can deploy the code to the staging area, making it available for testing purposes. Software such as Selenium can then be used to carry out the necessary testing.
  5. Once testing has been completed, Jenkins sends the relevant information to the production server for deployment. Similarly, Puppet and other configuration management technologies are responsible for providing and managing the production server.
  6. After deployment, Nagios does constant monitoring.
  7. Your team may now test features in reproducible scenarios thanks to Docker containers.

Why should we care about DevOps?

DevOps offers a range of technological advantages, such as the early detection of potential issues and prompt resolution, simplified management of systems, and the ability to deliver software to users on a continuous basis. In addition to these technical benefits, DevOps also offers commercial advantages, such as improved working conditions, increased collaboration, and enhanced communication among team members.

What is the function of configuration management in DevOps?

Configuration Management is a helpful tool for the coordination of changes across multiple systems. It streamlines the management of multiple servers and enables the standardization of resource configurations. This ensures that the resource setups are consistent and efficient, making the process of managing multiple servers much more straightforward.

What are the top tools used in DevOps?

Git, Jenkins, Nagios, Docker, Selenium and Puppet or Ansible are some of the most commonly used DevOps technologies when it comes to Configuration Management and Deployment. Git is a version control system tool, Jenkins a continuous integration tool, Nagios a continuous monitoring tool, Docker a containerization tool, Selenium a continuous testing tool, and Puppet or Ansible are Configuration Management and Deployment tools.

Where can I see a complete log of all files affected by a certain commit?

  • The -r option tells the programme to provide a detailed listing of each file.
  • The files that were modified or added during a certain commit are indicated by the commit hash.

In what ways are modified versions of core plugins deployed?

Here’s how to release a modified version of a core plugin:

  1. Save the.hpi file in the plugins directory of your $JENKINS HOME.
  2. Get rid of the folder containing the plugin’s source code
  3. Make a new, empty plugin file.
  4. Reboot Jenkins
