Continuous Delivery (CD) in Agile methodology is a software delivery process of short iterations and releasing new functionality once, it is ready for release....

Key Concepts and Principles of Continuous Delivery in Agile

Sprint-based releases: In agile scrum, every sprint becomes a potential release candidate enabled by the continuous delivery process. This leads to smaller and more frequent deployments for successful releases. Automation of all processes: Automating the build, testing, delivery, and deployment processes is the most important step in implementing continuous delivery in Agile. Build Quality: The quality of process and delivery is an integrated part of every continuous delivery in agile. All new piece of delivery is passed through automated tests to ensure everything is bug-free and meets the performance metrics for the highest quality. Reduced Risk: The automated testing and build process helps to avoid any bugs reaching production. This leads to quality delivery, improved software stability, and higher user satisfaction. Faster Feedback: Continuous delivery helps software features be added to production frequently and at a faster pace, which helps to receive quick user feedback, allowing the scrum team to adapt and iterate quickly. Improved Team Focus: Continuous delivery enables developers to focus on development and providing solutions, while it handles the deployment and delivery....

Key Steps in the Continuous Delivery Agile

Code Development: While implementing the continuous delivery process in Agile for software development, the developers work on small and manageable pieces of functionality like user stories and write software code to add these features. Continuous Integration: Continuous integration occurs before the continuous delivery, when developers integrate their code changes to a version control repository like GIT. Artifact Generation: When successful integration and testing are done, the continuous integration process generates the artifacts such as compiled binaries or deployable packages for deployment to the server. Deployment Automation: Once the artifacts are generated the automated deployment takes these and deploys to the target server environment across different stages. Release to Production: In the continuous delivery process, once the automated tests in staging environment pass for the changes completed, the software changes are released to the production environment using different deployment methods to avoid any downtime. Monitoring and Feedback: After deployment is completed in production for particular release, continuous monitoring is done to gather any issue logs and other metrics to gather feedback on the performance and behavior of the application. Continuous Improvement: The continuous delivery in agile emphasizes continuous improvement and delivering value to customers continuously and in a more effective way....

Benefits of Continuous Delivery in Agile

Faster time to market: Continuous delivery in agile helps in incremental releases to get features to users quickly in line with customer needs and market competitiveness. Increased Agility and Flexibility: The continuous delivery process helps in the ability to respond quickly to any requirement changes or market conditions. Smaller and frequent releases help to avoid longer wait time for integrating any new features and improvements. Improved Software Quality: Frequent testing and monitoring of delivered features with continuous delivery helps in a more stable and reliable software. Business Value: Continuous delivery leads to improved velocity, business value and higher productivity delivering value to customers. Consistent and Repeatable Process: Continuous delivery process relies in automated and standardized process to ensure consistency across cross functional teams which helps to maintain a reliable and repeatable release pipeline. Enhanced Collaboration: Faster and continuous feedback from continuous delivery helps in closer collaboration between all team members including developers, QA Team and all stakeholders....

Conclusion

Agile methodologies advocate a culture of efficiency, responsiveness, collaboration and responding to change quickly. With the continuous delivery process implementation, these agile principles are aligned well with the iterative and customer-centric development and delivery process. This helps to make the release process highly predictable, reliable and sustainable....
