Continuous Delivery and Continuous integration are the wide-spread and widely used term in the Agile framework. I have heard on Continuous delivery since I worked in agile with various organizations. Now let us discuss on why continuous delivery is taking the front seat for any organizations. Because it bring business a sustainable development environment in a very competitive market condition. It is one of the top technical practices widely used in agile and lean framework especially during project execution stage.
Continuous Delivery Business Benefits:
- Creating a sustainable environment with competitor
- Creating an opportunity for entering quickly to market.
- Stay away from OR reduce the impact of risk and external threat.
- Understand the business need early.
- Adjust changes at any course during the project.
- Generating happy customers.
- Reduces last moment release surprises by getting early feedback.
- Achieving zero defects for releases.
- Reduces complexity for multiple branch code merging, Build effort
- Simplifying the discrete nature of delivery.
Now let us discuss on Discrete vs. Continuous delivery.
Continuous delivery is mainly recommended for matured agile teams. It is fruitful once the team has reached a sustainable development after experienced with agile practices across few sprints. It brings a tight integration between development, builds and release process.
Conditions of satisfaction
- A highly disciplined cross-functional team, mastering with technical practices like test driven development.
- DevOps, Privilege team in controlling environment from development till production for a Continuous Delivery.
- Right infrastructure, tools, and latest cloned production environments to make Continuous Delivery.
- Low dependency between environments or applications to support a Continuous Delivery pattern.
- A single source code repository with minimum code branches.
- A well-defined automated test, build and deployment environment.
How to meet a continuous Delivery?
- Check out the piece of code, or write a new piece.
- Merge your code into existing code reflecting latest changes.
- Commit all tested code into the code repository.
- CI server will display a build link. Start to build links.

Continuous Delivery is a set of practices which focuses on a smooth delivery of business needs by frequently integrating and releasing new work items as soon as it is completed as per acceptance criteria. – Pratap Sahoo
Deployment with Jenkins
Jenkins is one of the popular open source CI servers. This tool created with JAVA with a simple and user-friendly GUI and widely used on IT projects for enabling continuous integration by automating builds since 2011. Continuous integration is enabled by automating builds soon after a developer checks in his/her code into version control. Jenkins provides a common platform to integrate various configuration management tools to enable all batch work to finish for a final deployment.
Continuous Integration = Repeat(Build, Compile the build, Automated test and build the package).
