In 99% of cases, a DevOps engineer does not exist as a single person. Often, it's a team of 2 and more engineers because DevOps covers so many skills and responsibilities that a single person cannot know all of this as thoroughly as you’d like him to. The fact of hiring a person who puts DevOps in his CV guarantees nothing. That’s why it’s the key to define clearly what job responsibilities these specialists need to take on and what your final goal is: managing cloud migration, building a software product from scratch, or ensuring your infrastructure security.
What is DevOps?
DevOps is the software development best practice that unites formerly siloed roles of development, IT operations, quality engineering, and security.
DevOps teams automate processes that originally have been manual and slow. They use a tech stack and tools that help DevOps engineers operate quickly and accomplish tasks independently (code deployment or infrastructure provisioning) that typically would require involving other teams, which increases an overall velocity.
As a result, the business adopting the DevOps culture builds reliable products that better respond to customer needs, delivers these products more rapidly, and competes more effectively in the market.
The DevOps culture gets divided into narrower sub-categories, for example,
- CloudOps is the practice of improving the performance of your applications and infrastructure in the cloud, automating continuous compliance, and setting up centralized control, agility, and scale across all environments.
- DevSecOps is the practice of introducing security earlier in the software development life cycle, including PCI compliance (the security of credit card transactions), CIS compliance (setting benchmarks for protecting the company´s systems and data from cyberattacks), patching, etc.
- InfraOps/SysOps is the practice of automating and optimizing cloud infrastructure operations, including performing predictive capacity planning, provisioning a new workload to the cloud, or scheduling a resource shutdown.
- and others.
Why Your Business Needs DevOps
Ensure software security to drive user satisfaction
DevOps helps create software products that have fewer bugs and vulnerabilities, boosting user satisfaction and your brand image. DevOps engineers widely use automated compliance policies, fine-grained controls, and configuration management techniques to retain control and preserve compliance.
Deliver rapidly and frequently to build a competitive advantage
DevOps teams innovate and improve an end product faster due to applying CI/CD pipeline that automates manual and slow processes and speeds up the software release from build to deployment. The quicker your development team fixes bugs and releases new features, the faster your business responds to customers’ needs, adapt to changing markets better, and gains competitive advantage.
Guarantee software reliability to bring positive UX
DevOps engineers apply monitoring and logging to stay informed of software performance in real time. Use CI/CD best practices to ensure that each software update and infrastructure change is functional and safe. These best practices are the key to maintaining high software reliability while delivering at a more rapid pace. As a result, your product and brand bring a positive experience for end users.
Scale software securely and easily to favor business growth
DevOps engineers use the microservices architecture to manage your infrastructure and development processes at scale. Besides, DevOps teams use Infrastructure as Code (IaC) for managing your development, testing, and production by automating repeating, manual processes. The IaC technique helps you manage complex or changing systems efficiently and with reduced risk.
Improved collaboration to drive higher performance and better results
The DevOps model implies building more effective teams with a focus on ownership and accountability. DevOps engineers cooperate closely, share many job functions and responsibilities, and combine their workflows. As a result, such an approach reduces inefficiencies and saves time due to avoiding long handover periods between developers and operations.

Must-Have DevOps Skills and Job Functions
Whatever your business needs are, the software development cycle remains equal:
- and the operational part (monitoring, maintaining, and troubleshooting).
To actively participate in each stage and perform effectively, make sure your DevOps team fulfills the core skills and job functions, essential for each stage of the development cycle.
Compared to traditional software development, in DevOps teams, engineers work along the entire software development lifecycle, from development and QA to deployment to operations. So each engineer in such a DevOps team develops a skillset not limited to a single function.
However, due to such diversity of functions, the DevOps label covers a vast array of engineers with various skills and responsibilities.
We know! It’s hard even to read such a list of skills thoroughly. Imagine how a single person can know all of this as thoroughly as you’d like him to. This is why, ideally, DevOps refers to a team and not a single person. Only such an approach will bring your business the expected outcomes.
1. Planning Skills and Responsibilities
- Understand customer requirements and project KPIs.
- Use Jira to optimize collaboration, prioritize tasks, and manage regular reporting on the progress.
- Manage Agile software development with Scrum to create iterative development and delivery process with constant feedback.
- Use Kanban boards to visualize progress.
- Create backlogs to plan further development adequately.
- Set strong cultural norms around information sharing and facilitating communication through the use of chat applications, issue or project-tracking systems, and wikis.
2. Software Developing Skills and Responsibilities
- Select and use a suitable development environment, e.g., IDEs like Visual Studio, Visual Studio Code, Eclipse for Java, or IntelliJ IDEA.
- Build the code into artifacts to deploy into various environments.
- Commit changes to a shared repository using a version control system such as Git.
- Run local unit tests, integration tests, load tests, API reliability tests, etc as an extra verification layer before integrating a new piece of code to validate updates and pre-emptively discover issues.
- Apply Trunk-based development methodology to merge small, frequent updates to a core “trunk” or main branch.
- Automate the creation and replication of multiple environments for testing in the cloud.
- Be skilled in AWS, Azure, and GCP to create and design serverless apps with AWS Lambda, Amazon API Gateway, AWS Amplify, Amazon DynamoDB, or similar tools for Azure/Google Cloud.
- Work with cloud-native architecture environments, perform load-balancing, autoscaling, clustering launches per region, queueing long-running tasks to create highly scalable systems in the cloud.
- Know and work with Kubernetes clustering: Amazon EKS, Azure EKS, and Google Kubernetes Service to automate many of the manual processes involved in deploying, managing, and scaling containerized applications.
3. Delivering Skills and Responsibilities
- Work with DevOps platforms that offer delivery automation, e.g., GitHub Actions and Azure Pipelines to decrease the deployment time.
