- 4. What is DevOps? DevOpsis the combination of cultural philosophies, practices, and tools that increases an organization’s ability to deliver applications and services at high velocity https://aws.amazon.com/devops/what-is-devops/

- 7. What is GitOps? GitOpsis a way of implementing Continuous Deployment for cloud native applications. https://www.gitops.tech/#what-is-gitops
- 8. What is GitOps? GitOps:versioned CI/CD on top of declarative infrastructure. - Kelsey Hightower -
- 9. What is GitOps? Setof practices to manage infrastructure and application deployment using Git as a single source of truth with declarative model
- 10. 1 GitOps Principles ➔ Describe theentire system declaratively ➔ The desired system state is versioned in Git ➔ Automatically apply approved changes to the system ➔ Ensure correctness and alert on divergence with software agents Source: https://www.weave.works

- 12. Set “annotation” Set “replicas” Set“image” nginx-deployment.yml
- 13. How GitOps Works? ➔ GitOpsarchitecture enables developers to manage infrastructure operations using Git as the only source of truth. ➔ Gitops uses the operator as a deployment synchronizer that will always compare the desired state and the actual state.

- 15. GitOps Workflow Actual State DesiredState Operator Ensure Actual State == Desired state
- 16. Advantages of GitOps ➔ FasterTime to Market ➔ Improve Security ➔ More Reliable ➔ Improved Developer Experience ➔ Auditable ➔ Standardized Operations across the Infrastructure
- 17. GitOps Best Practices ➔ SplitRepo: One For App Repository, Another For Environment/Config Repository ➔ Test the Manifests Before Commit ➔ Git Manifests Should Not Change Due To External Changes ➔ Plan How to Manage Secrets
