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 containerisation platforms and container orchestration tools
DevOps jobs and responsibilities include DevOps evangelist, automation expertise, release management, software development, software testing, security engineering, and quality assurance. Soft Skills any DevOps engineer should possess are fostering a collaborative environment, imposing end-to-end responsibility, encouraging continuous improvements, automating everything, and focusing on customer requirements.
DevOps resume should include skills like Collaboration Skills, Operating Systems, Unix/Linux, Communication Skills, Networking Protocols, GIT, Problem Solving, Build and Release, Jenkins, Creative Thinking, Source Control, Puppet/Chef, Critical Thinking, Deployment, Salt or Ansible, Adaptability, Configuration Management, Docker, Active Learning, Containers, AWS and VMWare or Cisco, Perceptiveness, Monitoring, Python or Perl, Leadership Skills, Programming, Apache or Nginx, Interpersonal Skills, Agile, Zabbix or Sensu.
These skills can be categorised into different management criteria of the project lifecycle that is included below:
Source Control, Continuous Integration, Configuration Management, Deployment Automation, Containers, Orchestration, Cloud Platform, Kubernetes, AWS, Git, Jenkins, Puppet, Jenkins, Docker, Bitbucket, Bamboo, Chef, VSTS, Vagrant, Mesos, Azure, TeamCity, Ansible, Octopus Deploy, Swarm, GCP and more.
DevOps resume should contain skills and specifics of how a candidate has used these skills in the profession and how much it has impacted the company’s business. Numbers should be part of the resume to give more weightage to the outline and in front of hiring managers.
DevOps is changing continuously, and thus, candidates should ensure his/her abilities and passion for learning new skills and tools in the resume. DevOps certifications are available, and if a candidate has completed any of these relevant to the job description, that must be highlighted at the start of the resume.
Automation reduces human interference and fosters speeds, improves consistency, enhances accuracy and reliability, and delivers high-quality project outcomes to clients. As every field is adopting automation, each DevOps candidate should have the knowledge and real-time experience included in the resume.
DevOps engineers must possess a lot of soft and hard skills difficult for one to gain and develop. DevOps resume must show the candidate’s passion and enthusiasm for what he/she does or willing to do for the company as a DevOps Engineer.
He/she should ensure a curious, empathetic, reliable, assertive, consistent, and proactive nature through his/her resume. It must reflect the ability to handle the tech side of the project, from deciding and using particular tools, managing infrastructure, and communicating with clients. DevOps is neither rocket science nor easy but worth becoming one!
