Templates are text files in YAML or JSON format. They describe the cloud objects that you want, including applications, resources, and services. AOS creates various cloud objects automatically from AOS templates. For more information about templates, see Templates (Cloud-Based Automation Scripts).
Stacks are collections of applications and cloud resources. The applications or cloud services in a stack are treated as a unit when being created or deleted.
The designer can be used to create, preview, and modify AOS templates. Template framework can be quickly formed by simple operations like drag, drop, linking, and zooming.
