DevOps has gained popularity in recent years because it helps organizations achieve faster time-to-market without compromising on quality or stability. It’s centralized in the concept of automating and streamlining the software development process so that organizations can deliver quality software faster and more efficiently. But what exactly is the working procedure of DevOps? Let’s take a closer look.
What is the Working Procedure for DevOps?

The goal of DevOps is to shorten the software development life cycle and provide continuous delivery with high software quality. This is achieved through automation, collaboration, and communication among teams involved in the software development process.
The first step in the DevOps process is to develop code changes. Developers write code and then commit those changes to a shared repository. Once the code changes are committed, they should automatically trigger a series of tests to ensure that the code is stable and does not break any existing functionality.
If the tests pass, the code changes are then deployed to a staging or production environment. In some cases, manual approval may be required before the code is deployed. However, with continuous integration and continuous delivery (CI/CD) pipelines, this process can be automated so that code changes are automatically deployed as soon as they are approved.
Once the code is deployed, it is important to monitor the new version to ensure that there are no unexpected issues. This is where DevOps tools come in to detect and diagnose any problems that may occur. By continuously monitoring and improving the software development process, organizations can deliver better quality software faster and more efficiently.
The working procedure of the DevOps methodology can be summarized as follows:
1. The development team develops the code and checks it into the version control system.
2. The code is then built by the continuous integration server.
3. Unit tests are run on the code to check for any errors.
4. If the unit tests pass, the code is then deployed to a staging server.
5. Functional tests are run on the staging server to check for any errors.
6. If the functional tests pass, the code is then deployed to a production
Thus, we can see that the DevOps process is a continuous cycle of development, testing, and deployment. The entire DevOps process is also automated using various tools. These tools help in automating various tasks such as code checking, testing, and deployments. Some of the popular DevOps tools include Puppet, Chef, Ansible, and SaltStack.

Here is an in-depth look at the DevOps software development practice, what happens in the working procedure of DevOps, and why it’s effective in delivering today’s business needs.
Continuous development
The continuous development strategy and its sub-strategies are interrelated. Thus, implementing them will allow organizations to achieve faster delivery, lower risks, and overcome bandwidth barriers significantly. Faster development can be achieved by automating the build, test, and deploy process can help speed up the overall development cycle.
Continuous integration
The key to a faster integration process is to have a continuous development cycle. In DevOps, developers are required to commit changes to the source code more frequently. This may be on a daily or weekly basis. Then, every commit is built and this allows early detection of problems if they are present. Building code is not only involved in compilation, but also includes unit testing, integration testing, code review, and packaging.
The code supporting new functionality is continuously integrated with the existing code. Therefore, there is a continuous development of software. The updates are released into the production environment on a regular basis. This way, bugs can be fixed quickly and new features can be added continuously.
Continuous testing
The key to faster QA in DevOps is the collaboration between the development and testing teams. In the traditional model, quality assurance is an afterthought that comes into play near the end of the development cycle. This can lead to delays and a lot of back-and-forth between the two teams.
With DevOps, quality assurance is built into every step of the process. Both teams are responsible for ensuring quality at every stage. This helps to avoid problems down the line and speeds up the overall process.
In terms of code development, the QA team pushes new code into production and DevOps facilitates a seamless deployment of infrastructure and tools. This helps to release code on a consistent basis and the responsibility for quality is shared between the two teams.
Overall, the key to faster QA in DevOps is collaboration and shared responsibility for quality assurance. By working together, the development and testing teams can avoid delays and release code more quickly.
Continuous monitoring
There are various ways to achieve a more efficient monitoring process in DevOps. Some of the most common and effective methods include automating monitoring tasks, using tools that provide real-time visibility into the system, and establishing clear communication channels between different teams.
Automating monitoring tasks can help reduce the time and effort needed to manually check the status of the system. This can be done by setting up alerts that will notify the team when certain conditions are met. For example, if the server is down or if there is a sudden spike in traffic.
Tools that provide real-time visibility into the system can also be extremely helpful in identifying issues as they happen. This includes tools that track performance data, errors, and log files. Having this information readily available can help the team resolve issues more quickly.
Finally, establishing clear communication channels between different teams can ensure that everyone is on the same page and aware of what is happening with the system. This can be done through regular meetings, chat tools, or email.
Continuous feedback
There are several ways to achieve faster feedback in a DevOps environment. One is to automate as many tasks as possible, including testing and reporting. This will reduce the amount of time needed to complete these tasks, which will in turn allow for quicker feedback. Additionally, by having a concrete understanding of the changes that have been made in the software lifecycle, team members can work more efficiently together. With rapid feedback, the operations team and developers can make better decisions collectively and enhance the app’s performance.
Continuous deployment
The key to achieving fast deployment in DevOps is to automate your review process. By automating your review process, you can release your deliverables faster and avoid context switching. Moreover, businesses should understand that if their review cycle is not automated, it will slow down the release process. Thus, DevOps can help rectify this worrisome business situation.
How to Implement DevOps in Your Team

The first step is to change the mindset of the members of your development and operations teams. Developers and Ops must learn about DevOps practices and be interested in the work of each other. In short, they must learn to communicate with each other effectively and embrace the changes that come with applying the DevOps culture. For those implementing agile development practices, learning the DevOps life cycle may be easier since the two concepts are somewhat similar. However, teams that are used to traditional software development practices like the Waterfall methodology may find it challenging to switch to a different software delivery process. The second step is to provide the right tools. DevOps requires a set of tools to automate various tasks such as code management for more efficient software development. Create a learning session wherein your team can learn what a continuous integration tool is or how they can utilize configuration management tools for a more efficient development process. The third step is to create a culture of collaboration and feedback. The DevOps software development lifecycle is incomplete without this process. Team members must be encouraged to collaborate with each other and give feedback frequently. By following these steps, you can gradually implement DevOps in your team and reap its benefits.
