Continuous Delivery Model

Every successful and well-organized modern software project requires a combination of continuous integration (CI) and continues delivery (CD). Continuous delivery is a widespread software delivery practice used by IT companies to provide custom functions in a faster, safer, and more permanent way. 

Continuous Delivery (CD) allows automating the entire software release process. The goal is to create a trustworthy and automated process that delivers software from the developer to the user. In turn, the programmer, getting rid of almost all the manual work, works more productively. 

CI/CD is a pipeline concept. It facilitates the merging of a new code into the main code base. The idea allows one to run various types of tests at each stage and complete it by launching with the deployment of the system in the actual product that end-users see.

Thus, developers need the continuous delivery model for running tests and deploying/releasing. The continuous delivery branching model, for example, allows the developers to run tests freely and make changes without destroying the main code line. The developers can develop, test, and modify the code in parallel or isolation and then merge it to a master.

Continuous Delivery Model—The Pros and Cons

Continuous delivery implementations pass through phases of maturity. The continuous delivery maturity model has five steps (level) - base, beginner, intermediate, advanced, and expert. There are also five categories–Culture and Organization, Design and Architecture, Build and Deploy, Test and Verification, Information and Reporting. Different types can fall under various levels, although it is desirable to maintain them somewhat close to each other. The company does not need to pass these levels sequentially and can use them as a base for evaluation and planning instead.

This continuous delivery model allows the business to receive a return on investment as soon as possible and also reduce risky and repetitive tasks. The pros and cons of the continuous delivery maturity model will help the company decide whether its implementation is the right step at this time.
