As you well know CI/CD, DevOps and Agile are three fairly popular and effective software development frameworks. Although they are different from each other, they have the ability to support each other, so when teams of developers discuss how to implement these approaches on a project, they are determining how best to use these tools to produce the most ideal technology solution. In the development industry, creating or building products has never been done with a single tool, and in our environment when software development companies implement these three models in an initiative, the results are usually transformative. For that reason in this article, we will review how these three sophisticated and profitable practices for software production are composed and what are their functional characteristics in order to establish the existence of a scenario in which one is better than the others.
We previously dedicated an article to deepen in all that CI/CD (Continuous Integration/Continuous Delivery) refers, so here we will address only the necessary aspects to develop our explanation. Continuous Integration/Continuous Delivery is a collection of operating principles and best practices that engineering and technology development teams leverage to incorporate and deliver source code modifications efficiently and reliably.
The goal of this methodology is to establish a sound strategy for building software and testing in an automated fashion. To this end, the members of the development team have the mission of integrating, in a shared repository and continuously, all changes or adjustments to the source code. This allows testing and compilation at each insertion with the objective of discovering errors and resolving them quickly, allowing the creation of a software creation lifecycle with automated tools which reduce efforts and increase results.
The purpose of this methodology is to keep the code in a deployable state. That is, its set of processes ensures that all configuration modifications, bug fixes and code updates can be released to a production phase without the need for manual checks. The purpose of CD is to enable development teams to release code in loops or short cycles to build, test and deploy software to shorten its final delivery to production. Generally speaking, CI establishes a lifecycle in which the effort to build software is reduced in order to test and integrate it, and CD creates loops where software is tested to verify its functionality in order to deliver the best quality solutions.
More than a DevOps methodology, it is a collaborative culture that focuses on ideas, technologies, processes and roles to streamline software production, making it more efficient and organized by sharing development processes and operations in a single framework. See our article to learn more about DevOps. Under automated infrastructure, DevOps teams develop software in small pieces in order to integrate, test, monitor and deploy it in short periods of daily work. This allows an increase in the frequency of deployments and a reduction in software release time. The purpose of DevOps is to eliminate the negative impact of professional overspecialization and indirect roles within development teams to ensure clean and effective software production. This is because a DevOps team has no internal barriers between the engineering and operations areas as all team members are trained in the skills of each role, ensuring better communication, participation and collaboration on each project.
Being the precursor methodology of CI/CD and DevOps, Agile Development recognizes as its main objective to deliver effective technology solutions based on frequent and iterative cycles in which collective participation is encouraged under the framework of values and techniques of the Agile manifesto. Its set of processes eliminates internal barriers within development teams and enables effective collaboration between key stakeholders (developers and customers) to accelerate delivery. On the one hand, this is possible due to its short lifecycles that also include customer feedback and on the other hand because its teams are borderless in their composition, making its members highly cooperative, self-organized and cross-functional professionals. In essence Agile seeks to empower all members, invite customers to be part of the team, adapt to change and reduce time to produce high quality software.
All three practices share the same goal: Produce the best software solutions in the shortest possible time. So:
On a practical level the only difference that exists between Agile, DevOps and CI/CD is related to the implementation of their processes, this means that none is better than the other in terms of results because as mentioned above each of these practices is oriented to help teams develop high-value solutions in the shortest possible time. Therefore, engineers or developers implementing any of these practices should be aware of the others and if they plan to move from one to another they should make sure that their teams and companies are prepared for the change so as not to affect the customer experience. So, in short it is worth keeping in mind that:
