Introduction to DevOps Principles
DevOps is a methodology that requires a clear focus on Principles, Values, and Practices. It is not only about Project Management, Infrastructure Building, Automation, and Culture. It has some core key aspects and three effective ways in which they can be framed with incremental way:
- Flow- Flow of work should be from left to right and understandable as well.
- Feedback- Continuous Improvement should be there with every release or a DevOps lifecycle. This can be achieved using feedback loops.
- Foster- FosterDevelop an environment and try to adopt it. Generate Experimentation and Risk-taking ability. Repetition of the same activity and practice to attain the goal with grace.
Let’s walk through some in-depth of DevOps Principles and Practices with real lie examples and scenarios. DevOps is not only a framework or methodology it possesses a lot many more facts and processes within it such as agile, lean and ITSM.
DevOps if compared with Agile has made a tremendous change in a way that it has helped to reduce the chaos between both IT and development team by breaking the teams into small teams, more frequent software releases, frequent deployments and continuous incremental improvements. DevOps also includes Lean principles such as increasing flow and reducing the stream of IT Value stream. It also requires an Agile method for all service and project management processes that will help in removing bottlenecks and achieve faster lead and cycle time.
Principles of DevOps
By adapting and adopting DevOps principles and practices from multiple frameworks more productivity and economic values for the business can be taken care of.
How First Principle and Practice Works in Real Life?
- Continuous Integration – Everyday developers are committing codes in a shared repository which is a good development practice.
- Continuous Delivery – Any software should be in a releasable state throughout its lifecycle.
- Continuous Deployment – Every change in each of its development phase should pass all automated tests at the time of production.
- Value Stream Mapping – A lean tool that helps in depicting the entire flow of information, material, and works across functional silos including quality and time.
- Theory of Constraints – A methodology for identifying the most limiting factor to achieve a milestone and then systematically improving the constraint until it is no longer the limiting factor.
How Feedback as a Second Principle and Practice Works?
- Production Logs: Logs are saviors or rescue to escape the errors of the everyday.
- Automated Testing: Manual testing sometimes does not result in much in what we expect at the End phase.
- Dashboards: Dashboards such as JIRA and KANBAN for entire project management or to keep track of each team developer’s development work.
- Monitoring or Event Management: Ansible tools to monitor the overall system configuration and health check of the builds.
- Process Measurements: How to measure the flow of the entire process from development to deployment.
How Foster help in Attaining DevOps Principles and Practices?
- Practices and self-feedback include continuous learning and experimentation
- Experimentation and learning
- The Deming Cycle[feedback loop]
- Using failure to improve resiliency
- A collaborative effort for learning
- The adoption of the Environment is the most important factor to foster with DevOps as it never stops.
DevOps Tools Capability
When a Team decides to adopt DevOps, it will most often deal with tools instead of principles, practices, and Values.
DevOps tools deliver the following things which can be listed as follows:
- Self Service Projects via project configuration portals.
- Dependency analysis and impact analysis.
- Automated builds, testing, and Deployment. Quality code and its enhancement across environments and servers.
Optimization of Resources
Another very important aspect and principles of DevOps is the Optimization of Resources. How can it be done?

- By Proper scaling of the entire infrastructure.
- Re-designing of the entire global services from stacked resources instead of using and wasting new ones.
Also, to transform a solution it is required to apply agenda’s across vendors, to operate the overall cost for application per user or transaction. Foundation or base is also one of the key aspects of some good values of DevOps, we can put time and effort to create a good new application environment, redeploy the application, promotion of application to a new lifecycle phase.
Adopting a DevOps Culture: Always a second thought will be given while adopting it why not it can be adopted for business solutions thoroughly? A question to think about it?
One notion to get it answered is it includes some difficult aspects to follow such as
- Get the right people together.
- Get everyone on the same page with sync.
- Build capabilities that lead to lasting change.
- Focus on critical behaviors.
- Experiment and Learn.
Ultimately, DevOps enables companies to deliver better software, faster by improving flow, shortening and amplifying feedback loops, fostering a culture of continuous improvement and continuous development.
Conclusion – DevOps Principles
Lastly, a conclusion can be made saying that focus to be kept should be DevOps only it will help and shape an organization with a transformation based on time-space trade-off required for integrating business, process, event processor by creating a complex application.
This has been a guide to the DevOps Principles. Here we also discuss its principles, tools capability, and optimization of DevOps. You may also have a look at the following articles to learn more –
