- 4. Software distribution and development changes
- 5. DevOps Principles Definition Collaboration - work as one team end to end Breakdown the barriers between developers and IT ops Continuous integration & deployment Treat Infrastructure as code Support business and IT agility Automate everything Test everything Measure & monitor everything

- 7. Coding Phase Developer creates a code. How and where to store it? How to get the following functionality? • Tracking all changes • Distributed to allow collaboration • Branching and merging • Option to switch across different versions Version Control System
- 9. AWS CodeCommit git push CodeCommit Git objects in Amazon S3 Git index in Amazon DynamoDB Encryption key in AWS KMS SSH or Smart HTTP • Data redundancy across Availability Zones • Data-at-rest encryption • Integrated with AWS Identity and Access Management • No repo size limit Secure, scalable and managed source control
- 10. Demo (Code Commit / Git)
- 11. Build and Test Phase 1. Developers deploy code to the version control system (CodeCommit, Git) 2. SysOps build and deploy the software to the testing / staging environment 3. Q&A team executes load and performance test so the software can be released for production use
- 12. AWS CodePipeline
- 13. AWS CodePipeline Continuous Delivery and Release Automation • Customizable workflow engine • Integrate with partner and custom systems • Visual editor and status Source Staging Region 2 Region 3 Build Unit Tests Deploy UI Test DeployDeploy Region 1
- 15. Deployment Phase Software has to be deployed to different environments (dev/test/staging/production) Deployment has to be automated as much as possible to minimize downtime In case of issues, it has to allow roll-back to the previous version
- 16. AWS CodeDeploy
- 17. AWS CodeDeploy • Automated application deployments to EC2, and any Internet-connected computer • Consistent and reliable releases, without downtime • Scale from 1 instance to thousands • Centralize deployment control and monitoring Coordinate automated deployments, just like Amazon
