DevOps is an integral part of every tech company these days. It has evolved over the years, resulting in a transformational role full of possibilities and opportunities. DevOps integrates IT professionals and software developers in a way that results in a more efficient workflow.
Top tech companies, including FAANG companies, pay high salaries and offer several perks and benefits to their DevOps engineers, which is why this field is very popular among software engineers and developers right now.
In this article, we explain how you can become a DevOps Engineer, their roles and responsibilities, qualifications, and skills required.
What is DevOps?
DevOps is where software development meets IT operations. DevOps engineers are masters at ensuring continuous delivery of high-quality software and shortening the systems development cycle. DevOps goes hand-in-hand with Agile development.
DevOps can be visualized as a workflow that emphasizes communication between IT professionals and software engineers in a production environment. DevOps focuses on automating infrastructure changes and software deployment.
Continuous deployment is at the core of all DevOps functions, continuously integrating development and operations into a streamlined process.
This way, turnover time is reduced, and companies can rapidly deliver software updates and security measures internally and externally.

What does a DevOps Engineer do?
DevOps engineers apply their technical expertise to create cloud-based solutions at scale. They also guide customers through transformational business solutions by combining philosophies, tools, and practices, that deliver end-to-end applications and infrastructure solutions.
DevOps engineers are expected to have technical depth and hands-on implementation experience with tools and practices in the DevOps toolchain. A DevOps Engineer should be able to design and code modules for applications, infrastructure, and processes.
DevOps engineers are also responsible for developing operations that efficiently balance service reliability and delivery speed. They must be skilled at using cloud platforms to deploy and monitor services, build software delivery pipelines, and manage incidents.
Senior DevOps engineers are expected to take on more responsibility. They are also expected to work independently with minimal supervision.

How to Become a DevOps Engineer
With a world of DevOps opportunities now in front of you, you must be wondering, how do I become a DevOps engineer? It’s quite simple.
Most big tech companies, like Facebook, Apple, Amazon, Netflix, and Google, prefer hiring candidates with tertiary educational qualifications in computer science with relevant industry experience.
DevOps roles are usually senior positions that must be backed with extensive Development or Operations experience.
To become a DevOps engineer, you must:
- Have an educational qualification in computer science focused on software development or an equivalent discipline.
- Have a strong knowledge base of cloud computing technologies such as Google Cloud Platform, Amazon Web Services (AWS), Microsoft Azure, and Terraform.
- Possess strong coding skills relevant to your industry.
How Long Does it Take to Become a DevOps Engineer?
Most FAANG companies look to hire DevOps professionals who have spent a considerable amount of time in either Development or Operations or both.
For instance:
- To become an AWS DevOps engineer, you need to have 5 years of experience as a technical specialist and 2 years of experience in programming.
- To become a DevOps engineer at Google, you need to have sufficient experience working with external partners/customers, automating infrastructure provisioning, continuous integration and delivery, and standard IT security practices.
Qualifications Required for DevOps Engineering Jobs
The qualifications required by FAANG and other Tier-1 tech companies for the role of DevOps engineer are:
- A Bachelor’s degree in Computer Science or Mathematics, a related technical field, or equivalent practical experience
- Experience in designing, constructing, and deploying scalable solution architectures
- Experience in writing software in Java, Python, JavaScript, Go, C++, or similar
- Experience in communicating technical concepts
DevOps Engineer: Skills
The approaches and skills required to become a DevOps engineer are:
- Programming: DevOps engineers must be proficient in at least one programming or scripting languagesuch as Python, Ruby, Perl, Java, JavaScript, Go, and C++.
Programming knowledge helps DevOps engineers debug codes, integrate database changes, and automate and deploy processes. It also helps in ensuring proper continuous integration/continuous delivery process. - Automation: Configuration, deployment, source code management— all these processes need to be automated. DevOps tools such as Git, Chef, Docker, Puppet, and Ansible help automate and monitor processes.
- Cloud services: DevOps engineers should handle cloud service models, cloud formation and architecture, deployment models, and cloud computing.
- Operating systems: You must have a general understanding of Linux and other operating system concepts such as process management, threads and concurrency, I/O management, and memory management.
- Software configuration and deployment: Knowledge of Docker and Puppet for configuration and deployment of applications in a production environment is desirable.
- Infrastructure as code: In this practice, DevOps engineers use configuration files for IT infrastructure management. Some commonly used infrastructure as code tools are Saltstack, Terraform, and Azure Resource Manager.
- CI/CD pipelines: Continuous integration/continuous delivery pipelines involve continuous integration of code into a common repository. It reduces costs and ensures a smooth workflow. Some of the most common CI/CD tools are GitLab, Jenkins, and CircleCI.
- Networking and security: You must also possess a working knowledge of networking concepts to ensure the security of the production environment at all stages of the product cycle.
According to experts, FAANG companies expect DevOps engineers to be skilled in:
- AWS
- Google Cloud Platform
- Python
- Kubernetes
- Terraform
