<h2 id="what-is-devops">What is DevOps</h2>
DevOps is fundamentally a collection of principles and methodologies for software development that emphasize the importance of collaboration, automation, continuous integration, seamless delivery, and continuous oversight.
Objective
Its ultimate objective is to establish a seamless and efficient path that extends from code creation to deployment and ongoing maintenance.
Background
DevOps was developed as a direct response to the difficulties and deficiencies of traditional software development practices. In the past, development and operations teams operated independently, resulting in substantial communication gaps, protracted release cycles, and limited collaboration. This lack of coordination frequently resulted in a variety of problems, such as delayed software deployments, frequent manual errors, and the arduous task of identifying and resolving issues. 
Recognizing the critical need for a more streamlined and collaborative approach, DevOps began to take shape. Although the term &quot;DevOps&quot; originated from pioneers Patrick Debois and Andrew Shafer around 2009, the evolution of DevOps had been occurring for some time prior to this landmark.
DevOps in Action
Here&#39;s an example of a Java code snippet that illustrates a fundamental DevOps practice, which involves automating the build process using a build automation tool like Maven:
<img src="https://assets.hicloud.sg/gringotts/What_Is_Dev_Ops_Java_Code_Illustration_6fd0d93699.jpg" alt="What Is DevOps Java Code Illustration.jpg">
In this example, the build() method serves as a depiction of the build procedure utilizing Maven. The ProcessBuilder is harnessed to execute the:
<ul>
<li>Maven command-line interface (mvn)</li>
<li>specified arguments (clean and install) to initiate and complete the build process.</li>
</ul>
This build sequence encompasses essential steps, including project cleaning, source code compilation, test execution, and artifact packaging.

<img src="https://assets.hicloud.sg/gringotts/20240122_161919_f73cce1294.jpg" alt="20240122-161919.jpg">
The DevOps process typically unfolds through a series of essential stages, each contributing to the efficient and effective development and deployment of software:
1. Plan: The development team and stakeholders work closely to define the goals, objectives, and requirements of the software project. This involves gathering user stories, prioritizing tasks, and setting clear development milestones, all to effectively guide the process.
2. Code: Developers collaborate to write and review code. Version control systems like Git are crucial in managing code changes so that multiple developers can work on the same codebase concurrently while maintaining version history and accountability.
3. Build: Code is transformed into deployable artifacts. Automated build processes make the deployment process more efficient by handling tasks such as code compilation, running tests, and packaging the code into executable files or containers.
4. Test: Testing is a fundamental aspect of DevOps. Automated testing is conducted to verify that the code meets quality standards. This includes running unit tests, integration tests, and various other tests to identify and rectify issues early in the development process.
5. Release: The software has passed the testing process and is ready to be deployed.
6. Deploy: Deployment is automated by Continuous Integration and Continuous Delivery (CI/CD) DevOps pipelines, enabling swift and dependable deployments. This automation can include multiple stages like staging and production, and it may incorporate advanced techniques like blue-green deployment or canary releases to reduce downtime.

7. Operate: Once the software is deployed, it enters the operational phase. Here, monitoring and managing the application or system is crucial to ensure its availability, performance, and security. Monitoring tools and techniques are employed to gather data on system behavior, detect anomalies, and facilitate proactive troubleshooting and optimization.
8. Monitor: Continuous monitoring is integral to DevOps. It involves the continuous collection and analysis of data regarding system performance, user experience, and other relevant metrics. This ongoing monitoring process helps identify areas for improvement, informs future iterations, and supports data-driven decision-making.
