DevOps is a set of practices that works to automate and integrate the processes between software development and IT teams, so they can build, test, and release software faster and more reliably. The term DevOps was formed by combining the words “development” and “operations” and signifies a cultural shift that bridges the gap between development and operation teams, which historically functioned in siloes.
SkillPractical provides the best DIY projects for DevOps from beginner to expert. These Java DIY projects will help the users to get prior knowledge on DevOps. Some of the important DevOps projects they cover are:
The CALMS Framework for DevOps:
Culture – it’s a culture change. And, a major part of a DevOps culture is collaboration.
Automation – helps eliminate repetitive manual work, yields repeatable processes, and creates reliable systems.
Lean – When we hear “lean” in the context of software, we usually think about eliminating low-value activities and moving quickly – being scrappy and agile.
Measurement-It’s hard to prove your continuous improvement efforts actually improve anything without data.

Best Practices for Effective DevOps:
While DevOps still means different things to different people, there has emerged a core of best practices that should be incorporated by companies looking at adopting DevOps.
- Active Stakeholder Participation- This is the fundamental guiding principle of DevOps. DevOps can succeed only if both the developers and the operations and support staff are truly committed to collaborating and using an integrated approach to achieve goals.
- Automated Testing- Automated regression testing is something agile teams adopt very often as it helps to fix problems right away and ship higher quality code. This works well in DevOps too as a dire need of operations staff is that the code shipped should meet a certain quality standard.
Integrated Configuration Management.
In a DevOps environment, configuration management applies not only to the current solution being worked on but also on the configuration issues between the solution and the rest of the organisation infrastructure. Integrated Configuration management helps operations teams see the potential impact of a new release more clearly which helps in making better decisions regarding when the release should be made.
- Integrated Change Management- With integrated change management, operations and development teams work together to understand how using different technologies will impact the organisation as a whole and then work toward managing that.
- Continuous Integration- With continuous integration, the code is tested and analysed whenever updated code is checked into the version control system. This provides immediate feedback on code defects which allows developers to build a high-quality solution with little risk.
Integrated Deployment Planning
A DevOps approach means operations engineers will be closely involved with the developers when it comes to planning the deployment of products as per an organisational deployment schedule.
Continuous Deployment
With continuous deployment, when integration is successful in one sandbox it is automatically promoted to the next sandbox and integration begins there. This continues until it reaches the point where it requires human verification. This usually occurs at the point of transition from dev to operations.
- Production Support- With DevOps, not only do developers work on new releases, but they also work on addressing critical problems with a solution that is already in production. Although they are the third and last team to get involved in solving production issues, it is a fairly common occurrence and gives them insights on production problems that help them design better solutions in the first place.
- Application Monitoring- This refers to the practice of monitoring and logging solutions real-time once they are in production. This gives us performance metrics that improve the reliability of the solution and prevent failures.
- Automated Dashboards- DevOps allows us to create automated dashboards for several key metrics. All metrics cannot be automated of course, but several key metrics can be seen real-time using automated dashboards and they provide critical business intelligence.
Here are some of the SkillPractical Real time Test on Toolchains of DevOps:
Coding – code development and review, source code management tools, code merging.
Building – continuous integration tools, build status.
Testing – continuous testing tools that provide quick and timely feedback on business risks.
Packaging – artifact repository, application pre-deployment staging.
Releasing – change management, release approvals, release automation.
Configuring – infrastructure configuration and management, infrastructure as code tools.
Monitoring – applications performance monitoring, end-user experience.
