There are intrinsic differences between these previous approaches and AEM as a Cloud Service:
AEM as a Cloud Service Benefits
Version Less AEM:
No need to worry about upgrading to the latest AEM version. When a new version is available, we can upgrade from the Cloud Manager CI/CD pipeline which is fully automated.
Quick Time to Market:
AEM as a Cloud Service assists you in quickly delivering the products, services, and experiences faster without developing customized content management systems.
Auto-scalable:
It can scale automatically based on traffic and operations. It requires less support and maintenance efforts.
Separation of code and content:
Custom code and configurations are clubbed into the AEM base image which is then used to create multiple Author and Publish nodes. The changes to the code and configurations are made only through CI/CD pipelines in Cloud Manager.
