In the present stage of software development, "DevOps," "CI/CD," and "Agile" are terms developers constantly come across. Often, these terms are used interchangeably. However, it is crucial to understand the difference between these terms and how they contribute to improved software operations and processes. By understanding these differences, developers can accurately employ these practices effectively.
DevOps, the amalgamation of "development" and "operations," was coined by Patrick Debois in 2009. It refers to the set of practices, tools, and philosophies that aid in delivering applications, products, and services more efficiently and quickly. DevOps began to gain popularity in the late 2000s, as software development teams and IT teams raised issues with the traditional processes where the development and operations teams worked separately. Through the integration of the software development and IT teams, this methodology encourages automation, cross-functional team communication, and collaboration. The teams are no longer isolated and focused on distinct functions. With automation, previously tedious and manual tasks are reduced, thus allowing the team to work across the entire application/product lifecycle- from development to deployment. As a result, the whole infrastructure and development lifecycle is seen as the entire team's responsibility. Two essential practices are the outcome of the DevOps mindset:

CI/CD (Continuous Integration and Continuous Deployment) is the set of practices and principles that help teams deliver accurate, reliable changes to the code. The CI/CD Model ensures automation tools and constant monitoring throughout the entire software development lifecycle. It is important to note that CI/CD is one of the practices that can be adopted by teams who work as per the DevOps mindset. By placing all the software code into a single repository, they can run automated tests continuously, thus speeding the process of releasing new updates.

This methodology focuses on the project management aspects of a software development team. The central premise of this methodology is the understanding of modern software development, wherein there can be no monolithic software development lifecycle. Therefore, rather than bringing changes together for one 'major' deployment/release, the team focuses on bringing in more minor and incremental changes. Consequently, it aims to empower team members to work closely with customers, produce software changes rapidly and embrace the constantly changing nature of software development. This framework encourages teams to work together in uncertain environments where developers must continuously respond to change. Several frameworks work with the Agile development approach, such as Scrum, LeSS, and Feature Driven Development (FDD), to name a few.

From the definitions of these terms, it is essential to note that these terms are not in opposition to each other as is often suggested. Instead, these are approaches that can be complementary and incorporated by teams from development to software deployment. However, for ease of differentiating, we have provided a diagrammatic representation of the "DevOps vs. CI/CD vs. Agile" issue below:
|A software development methodology highlights the benefits of the development and operations teams working together rather than in silos.||Agile methodology highlights the need for constant development and testing throughout the entire software development lifecycle.||Continuous Integration & Continuous Delivery refers to the practice involving monitoring and automation tools for reliably changing codebase.|
|DevOps bridges the gap between the developers/testers and the IT/operations team.||Agile as a project management approach focuses on bridging the gap between the customer and their software requirements and the testing/developer team.||CI/CD is one of the workflow practices adopted by DevOps practitioners. Other practices within DevOps philosophy include microservices, IaC, etc.|
|DevOps tools are engineered to enhance the communication and collaboration between product managers, developers, and the IT team.||Agile tools are primarily oriented toward increasing project management efficiency.||These tools are primarily centered around automating the Continuous Integration process.|
|An example would be Azure DevOps, a cloud-native SaaS platform offering solutions to build DevOps pipelines.||An example of Agile development tools that encourage iterative processes would be Atlassian Jira. In addition, with integration tools like IBM Cloud Pak, you can begin the journey towards integrating the Agile approach.||Jenkins is a popular CI CD tool with a CI automation server and the ability to deploy code with Continuous Delivery.

We have explained how DevOps, CI CD, and Agile development differ from each other, along with an overview of the tools employed to implement and automate these frameworks’ processes more efficiently. However, the problem of how to integrate and implement the tools and best practices remains to be solved.
