2. OpenGitOps(https://opengitops.dev/), a CNCF project defines GitOps
principles as:
●Declarative
⦿A system managed by GitOps must have its desired state expressed declaratively.
●Versioned and Immutable
⦿Desired state is stored in a way that enforces immutability, versioning and retains a
complete version history.
●Pulled Automatically
⦿Software agents automatically pull the desired state declarations from the source.
●Continuously Reconciled
⦿Software agents continuously observe actual system state and attempt to apply the
desired state.

3. ●Accelerated Development and Deployment
⦿Simplify and accelerate deployment processes.
⦿Deploy changes faster and more frequently.
●Enhanced Recovery and Reliability
⦿Easily revert to known-good configurations in case of errors.
⦿Minimize downtime and impact on users.
●Consistent Environments
⦿Ensure consistency in configurations across different environments.
⦿Reduce the risk of configuration drift.
●Comprehensive Version Control and Auditing
⦿Track changes to infrastructure and deployment configurations over time.
⦿Enhance traceability, accountability, and facilitate audits.

5. What is an Application in Choreo?
●An application in Choreo
consists of one or more
projects, each containing
components like services, web
apps, API proxies, webhooks,
tasks, event handlers, and test
runners. These components
work together to provide
seamless digital experiences.

Outcome: Accelerated Development and Deployment
Choreo supports parallel deployment tracks, allowing each branch to maintain its own API version while
enabling rapid, concurrent development.

10. Build History and Rollback Capability
10
Outcome: Enhanced Recovery and Reliability
Choreo maintains build history with commit details, allowing teams to redeploy previous builds
efficiently and ensure reliable rollback when necessary.

11. Environment-Specific Configuration Management
11
Outcome: Consistent Environments
Automated configuration value injection ensures secure, environment-specific settings,
supporting consistent and reliable deployments.

12. Integration Testing as a First-Class Component in Application
Architecture
