What are the Fundamental DevOps Principles
CIO Review APAC | Tuesday, August 22, 2023

DevOps encourages better, more consistent communication, collaboration, integration, visibility, and transparency between application development teams and IT operations counterparts.
FREMONT, CA: DevOps is a set of practices, tools, and a cultural philosophy that automates and integrates the processes of software development and IT teams. It prefers team empowerment, communication and collaboration across teams, and technological automation. The DevOps team is made up of developers and IT operations professionals who work together to improve the speed and quality of software deployment throughout the product lifecycle. It's a new way of working, a cultural shift with far-reaching consequences for teams and the organisations in which they work. It employs the tools to automate and accelerate processes, and hence ensure transparency. It is a continuous process since practitioners use the infinity loop to show how the different DevOps lifecycle stages relate to one another. Even though it appears to flow sequentially, the loop represents the need for constant communication and iterative development throughout the entire lifecycle.
DevOps is a collection of tools that work together to discover, plan, build, test, monitor, operate and provide continuous feedback. Organisations and teams must frequently experiment with different tool combinations to find the best toolchain.

Discover
A DevOps team conducts research and defines the scope of a project. It includes tasks like user research, goal setting, and success definition. Jira product discovery organises and prioritises this information into actionable inputs for development teams. Product discovery is the first activity in the design process and serves as the foundation for decision-making. One can gather all relevant information about any user issues during product discovery and then provide solutions.
Plan
It suggests tools that enable development and operations teams to divide work into smaller, more manageable chunks for faster deployments. This allows you to learn from users more quickly and aids in the optimisation of a product based on feedback. Look for tools like Jira that allow for sprint planning, issue tracking, and collaboration. Another good practice is to collect user feedback regularly, organise it into actionable inputs, and prioritise those actions for development teams.
Build
It is critical to have source control over your code. Source control tools aid in the organisation of code into different chains, allowing you to see every change and collaborate more easily by sharing those changes. Git is a version control system that is free and open source. It supports branching, merging, and rewriting repository history very well, which has resulted in many innovative and powerful workflows and tools for the development build process.
Continuous Delivery
It refers to the practice of checking in code to a shared repository several times per day and testing it each time. This enables developers to automatically detect problems, fix them when they are easiest to fix, and roll out new features to your users as soon as possible. Branching is required for code review via pull requests, which is popular. The DevOps North Star workflow results in fewer and faster branches while maintaining testing rigour and development speed.
Test
Exploratory testing, test management, and automation are just a few of the capabilities and requirements that testing tools can meet. Automation, on the other hand, is a critical function in the DevOps toolchain. You can improve software quality while lowering risk by automating tests early and frequently. Development teams can run automated tests on a variety of topics, including user interface testing, security scanning, and load testing, repeatedly. They also generate reports and trend graphs to help identify risky areas.
Operate
From start to finish, manage the delivery of IT services to customers. All practices involved in the design, implementation, configuration, deployment and maintenance of an organisation's IT infrastructure are included.
Observe
Identify and resolve issues that affect product uptime, speed, and functionality as soon as possible. Notify your team automatically of changes, high-risk actions, or failures so that one can keep services running.
Deploy
Continuous deployment enables teams to automate the regular release of features into production. Teams can also use feature flags to incrementally and methodically deliver new code to users rather than all at once. This method improves software development teams' velocity, productivity, and long-term viability. The benefits of DevOps are improved and faster product delivery, enhanced scalability and accessibility, reduced complexity and faster problem resolution to name a few.
DevOps aims to eliminate silos and make the development life cycle faster, more automated, and more collaborative, whether between teams or across groups. Before choosing DevOps tools that integrate, businesses must examine the current software development and IT operations processes and identify areas for improvement.
