Trunk-Based Development in Software Development

In earlier days of software development, programmers didn't have the richness of modern version control systems but they developed two versions of their software concurrently as it means of monitoring small changes and backing them if possible and only in necessary conditions. As time increases it has become more costly, and inefficient.

At present various version control systems are developed and managed. It made it more mature, and various departments have merged which enables programmers to find bugs or errors more easily. As of today, most developers hold one of the two development models to deliver quality software which is Git flow and trunk-based development. Trunk-based development is an additional open model since all developers have easier access to the main code which also enables teams to implement CI/CD and so on.

What is Trunk-Based Development?

In software development, Trunk based development is a version control management technique or practice where developers from various organizations merge small, regular updates to a base code.

• It is a common practice among DevOps teams and part of DevOps lifecycle since it streamlines merging and integration phases. Copies made from the source code is called branches.
• It is considered as an branching model. In fact, trunk-based development is a required practice of CI/CD. As codebase
