Hi @raeesuzhunnan
In AEM as a Cloud Service (AEMaaCS), Cloud Manager handles the deployment process, ensuring that every build is first deployed to the Stage environment before proceeding to Production. This approach guarantees build stability and maintains zero downtime in the Production system, avoiding any disruption for end users.
You can explore the deployment pipeline concepts in detail here:

With AEMaaCS and Cloud Manager, deployment to Production is strictly gated by the successful deployment to Stage. If any issues are detected with the build, Cloud Manager prevents it from progressing to Stage, thereby safeguarding the stability of the Production environment.
