# CI/CD --- * Intorduction to CI/CD * History and Evolution * Continous Integration * Continous Deployment * Do it on your own --- ## Intorduction to CI/CD --- * **Continuous Integration (CI):** This is the practice of merging all developers' working copies to a shared mainline several times a day. The main goal is to prevent integration problems, commonly known as *"integration hell."* * **Continuous Deployment (CD):** Once all code changes are tested, they are deployed directly to the production environment. It emphasizes a fully automated release process. --- ### Advantages: * Abstracts away deployment logic * Accelerates the development process * Enhances code quality * Reduces time to market --- ### Disadvantages: * Initial configuration overhead * Mainting costs --- ## History --- ### Scrum  --- ### Cloud Native * Virtual computing * Cloud provider * Docker * Microservices --- ## Continous Integration --- -3.png?width=650&name=Continuous%20Integration%20Tools%20(V4)-3.png) --- * **Build:** Make sure that you build it on same platform than deployment * **Test:** Unit Tests, Integration Tests, but also Linting * **Report:** Code metrics, Performance metrics --- ### Build * Can be a Software Package like with Hitachi * Can be a Docker container * Can be only code optimization like for Javascript --- ### Azure Devops & Bitbucket, etc * Can all be configured on their platform * If we work with Azure Cloud Platform there exist already some easier integration with the Azure Cloud * Can also be done manually, althrough requires a lot of overhead --- ## Continous Deployment --- * Everything in tha cloud plzzzz (except if you can't) * Advantages like: Blue-green deployments, canary releases, feature toggles. * Monitoring * Rollbacks ---  --- # Now you implement it on your own! - https://dev.azure.com/originate-training/ci-cd-training/_build - https://portal.azure.com/#@originate.ch/resource/subscriptions/50495108-be87-45dd-a897-faae33b46d7d/resourceGroups/ci-cd-training/overview - https://bitbucket.org/originategmbh/workspace/projects/IN
