DevOps thought bubbles with a person standing behind them

 According to Grand View Research, the DevOps market will reach $12.85 billion by 2025. Driving this growth is the increasing enterprise digitization to automate business processes and the increase in cloud technologies use and agile frameworks across a range of industries.

A wide range of tech companies and tech-driven organizations of all sizes, such as Netflix, Amazon, Adobe, and Facebook, often look to add additional DevOps engineers to their teams. On top of the demand, DevOps engineer came in at No. 5 on Glassdoor’s 50 Best Jobs in America for 2021.

Learn all about what a DevOps engineer is, what they do, and how to get into this role below. 

Who is a DevOps engineer?

A DevOps engineer is a tech expert who understands the entire software development lifecycle — a six-stage process that guides the software development process — and uses various engineering tools and techniques to develop pipelines and solve operational challenges.

DevOps engineers encapsulate the depth of knowledge and years of experience in a wide array of open-source technologies and tools. They’re masters in coding, integrating, scripting and testing, and they possess extensive data management skills. 

For this reason, they’re rightly called ‘Special Forces’ who hold core attributes around open communication, collaboration, and reaching across functional borders.

Typically, DevOps engineers are senior developers or system administrators with business, configuration, operation, automation, and leadership skills. 

Some people argue the DevOps engineer title is antithetical to the DevOps practice, as it creates another silo. Thus, some companies have people who perform DevOps management tasks without the DevOps engineer title.

What DevOps engineers do?

As the term suggests, DevOps engineers facilitate collaboration between the development and operations teams to enhance the product quality and streamline workflow. They oversee the efficient release and use of new software code and products.

DevOps engineers are responsible for an application or piece of software from development through testing, infrastructure deployment, application deployment and end-user feedback. They also implement changes based on the input. 

DevOps engineers typically spend much of their time researching new technologies that can improve efficiency. They deploy scalable applications and integrate infrastructure with the application deployment process.

Here are a few tasks and duties of a DevOps engineer:

  • Designing tools and processes for managing infrastructure
  • Working on multiple platforms across various programming languages
  • Automating testing and deployment processes and workloads across cloud providers
  • Supporting internal and external stakeholders on different platforms
  • Creating tools and processes for increased user satisfaction
  • Managing version control through Git or similar systems

How to become a DevOps engineer

To become a DevOps engineer, you’ll need technical and interpersonal skills, as you’ll act as a catalyst to break the communication and operation barriers between the development and operations teams in organizations.

The DevOps engineer role is typically a senior position that demands extensive industry experience. Thus, employers might prefer candidates with a tertiary qualification in computer science or related fields and industry experience.

Several career paths lead to becoming a DevOps engineer. Below is a common approach many DevOps engineers take.

Step 1: Earn a bachelor’s degree

Suppose you wish to become a DevOps engineer. In that case, the logical first step is earning a bachelor’s degree in a discipline related to math, computer science or electronics engineering, focusing on software development. 

Step 2: Earn a master’s degree:

Completing a master’s degree in software development will help you advance your DevOps engineer career. You will learn skills in different aspects of software development, like coding and emerging technologies.

If you are a working professional, consider an online master’s program to help balance your career and education.

Step 3: Acquire the necessary skills

DevOps is a vast environment that covers almost all technologies and processes. Thus, technical skills are crucial to land a job. 

Below, we’ll outline the complete DevOps engineer roadmap to acquiring the necessary skills.

Build your knowledge of industry-relevant coding language

As a DevOps engineer, you’ll use different software and plugins for a continuous integration and continuous delivery (CI/CD) pipeline. CI/CD pipeline automates the software delivery process by building code, running tests (CI) and securely deploying an updated version of the application (CD). Automated pipelines help remove manual errors and aid fast product iterations. 

You can write versatile, scalable and error-proof code if you have a good grip on some of the popular programming and scripting languages. It will also help to brush up on Java, Python, JavaScript and Powershell for windows.

Understand different OS concept 

A sound understanding of the OS concepts will help you be more productive in your programming, including writing codes faster, interacting with input-output devices and communicating with the other OS. 

Try to learn at least process management, sockets, virtualization, I/O management, file systems, and threads and concurrency. Since most DevOps engineers work in Linux, you should consider going through the Linux Administration Bootcamp to learn about Linux OS.

Learn about managing servers

You’ll have to manage a group of servers instead of individual servers. It’ll help to familiarize yourself with web servers like Nginx, which you can use as a reverse proxy, mail proxy, load balancer and HTTP cache.

Networking and security

The world is more connected than ever, making networking and security essential concepts to a career as a DevOps engineer. Learn basic networking concepts like DNS firewalls, IP addresses, and ports. Also, understand the standard rules of networking, such as TCP/IP, HTTP, SSH, and FTP.

Setting up your machine

As a DevOps engineer, you should know when to and how to set up your machine. 

A DevOps engineer should be proficient in setting up web servers like Tomcat, IIS and Apache. They should also be knowledgeable about the caching server, reverse proxy, load balancer and firewall.

Learn infrastructure as code

Learning infrastructure as code is one of the most crucial aspects of becoming a DevOps engineer. 

DevOps engineers should know about containers, like Kubernetes and Docker, infrastructure provisionings, like Terraform and Cloud formation, and configuration management tools, like Ansible, Puppet and Chef Salt.

Learn CI/CD tools

Setting up a pipeline for CI/CD is something DevOps engineers will always have to do. Though there are many tools, like Jenkins, Drone and TeamCity, in the CI/CD space, it’s best to learn at least Jenkins, which is the most widely used and likely the most sophisticated CI/CD tool available.

Learn to monitor software and infrastructure

Besides setting up and deploying, DevOps engineers are also responsible for monitoring applications and software. Depending on your company’s preferred tool, learn to use web application performance and monitoring tools like Datadog, Monit, Nagios or New Relic.

Learn about cloud providers

Cloud is growing and will continue to become more prominent in the near term. Sooner or later, you’ll have to move your applications to the cloud. Hence, build your knowledge in one or more cloud technologies, including Amazon Web Services, Google Cloud Platform, Terraform, or Microsoft Azure.
