Section 26.254 Automating Application Development

Question 1

Automating Application Development

Answer 1

Enhances efficiency, consistency, and the quality of software products

■ Automation: In application development, it involves using technology to manage, test, and deploy applications with minimal human intervention

Continuous Integration and Continuous Deployment (CI/CD) significantly improve software efficiency, consistency, and quality

Question 2

Continuous Integration (CI)

Answer 2

● Developers merge code changes frequently in a central repository

● Automated build process verifies each check-in and detects problems during integration

● Automation tools manage code integration, provide notifications for conflicts or errors

● Automated tests ensure software quality after integration

● Developers receive feedback on detected issues to make necessary
corrections

● Release: Process of finalising, preparing new software or updates Enabling software installation and usage

● Deployment: Involves automated process of software releases to users. Actual installation of software in a new environment

Question 3

Continuous Integration and Continuous Delivery (CI/CD)

Answer 3

CI/CD includes continuous integration

● Continuous Delivery (CD) ensures code is always deployable after every change

○ Automated testing and build processes

○ CD stops short of automatic production deployment

○ CD is part of the release process

○ Full deployment process is automated only to a certain stage:
■ Doesn’t deploy into the production environment automatically

○ Deployment to production environment is a manual business decision

○ Allows flexibility in timing, market conditions, and stakeholder readiness

Question 4

Continuous Deployment

Answer 4

● Takes CI/CD further by automatically deploying code changes to testing and production environments

● All changes passing through the production pipeline are fully released with no human intervention

● Automation ensures consistent deployments, faster releases, and offers rollback capabilities

● Requires a paradigm shift, more developer involvement in the
deployment process

● Promotes increased communication and collaboration within teams for collective responsibility

Question 5

Benefits of CI/CD

Answer 5

● Adapting to changing market demands more quickly

● Efficient workflow from development to deployment

● Improves code quality, streamlines deployment processes, and allows
flexible production release

● Reduces deployment risks and enhances software reliability
