What is DevOps?
DevOps is a set of principles and methodology that has brought cultural change and improved project efficiency. DevOps combines practices of software development (Dev) and IT (Information Technology) operations (Ops).
DevOps’ aim lies in shortening the system development life cycle and providing continuous, high-quality software delivery. A combination of agile philosophy and lean thinking unites each team in the project with tight integration.
Developers, system admins (sysadmins), QA (Quality Assurance) engineers work closely and together for the project deployment, writing scripts, and figure out issues in testing, verifying, and deploying the project. A DevOps process has eight stages viz. plan, code, build, test, release, deploy, operate and monitor. DevOps engineers are responsible for handling all these stages efficiently to deliver projects within a timeline satisfying all customer requirements.
Who is a DevOps Engineer?
DevOps engineer is a person having an understanding of the software development life cycle and various automation tools used in the development of digital pipelines such as CI (Continuous Integration) /CD (Continuous Delivery) pipelines.
He/she uses the DevOps methodology to improve response to changing environment, improve deployment frequency, a lower failure rate of new releases, shorten troubleshooting time, faster recovery in the meantime, speed up market time, and create a streamlined development process.
DevOps engineers are either developers (interested in network operations and deployment) or sysadmins (interested in coding, scripting, and development), improving test and deployment plans.
DevOps jobs are increasing in multiple, but there are no specific criteria applicable while hiring a DevOps engineer. Though it is a new position emerging, hiring managers are also not so clear with the particular skill set or ideas they must look for in applied candidates for the position of ‘DevOps’ engineer.
Suppose a candidate is having experience in the development or networking but not specifically about DevOps. In that case, that candidate is not considered a fresher, as DevOps skills include both developer and network manager skills.
While writing a resume for DevOps, even writing decades of experience will not be enough as it is continuously evolving, updating required skills, and needs dozens of skills and tools. A candidate looking for a DevOps role should include all the skills, tools, and experience relevant to the job description provided by the hiring manager or the organization.
A general list of talent set every DevOps engineer should possess, and DevOps resume must contain most of these skills, as given below:
- Hands-on practice and knowledge of source code management and scripting
- Proficiency in CI/CD pipelines
- Automation and integration tools understanding and experience
- Good knowledge of cloud service providers
- A clear understanding of infrastructure as a code and how to achieve it
- Proficiency in software containerization platforms and container orchestration tools

What are the must-have soft skills for a DevOps Engineer?
DevOps aids in the speedier release of new software and apps. It is, however, vital to have a certain set of soft skills on your side if you are to succeed. Empathy, communication skills, integrity, learnability, and resilience are few of the most important soft skills one must possess in addition to their technical skills in DevOps to make sure they not only stand out but also reach higher levels in their workplace. Furthermore, the willingness to always keep accepting your mistakes, improving with technological advances, discovering new practices, and finding performance improvement tools makes your DevOps journey easier as it is an ever-changing field.
How can the eight stages of the DevOps process be explained?
The Plan stage encompasses everything that happens before the developers start writing code. In the Code stage, code-styling is enforced and code anti-patterns, in addition to the typical toolset of a software developer, are developed. In the Build phase, developers commit their code to a common code repository once they have completed a task. For the Testing phase, the code is moved to a staging environment for more in-depth, out-of-band testing. The Release phase is a DevOps pipeline milestone at which we declare a build ready for deployment into the production environment. Finally, a build is ready for prime time and is sent to production. Customers are currently using the latest release, which is now live. Monitoring the environment is the last phase of the DevOps cycle.
Why is DevOps important?
DevOps is more of a collection of processes that work together to bring software development teams and processes together. The appeal of DevOps stems from the fact that it allows businesses to generate and improve products at a faster rate than traditional software development approaches. Faster innovations, shorter development cycles, reduced deployment failures, and improved communication and collaboration are some features that make it one of the top choices. Additionally, more stable operating environments, increased efficiencies, reduced costs, and IT headcount are a few reasons which makes DevOps very important.
