AOS.Stack

Element Description

The AOS.Stack element is a Huawei PaaS solution deployment template. It is used to create stack resources of AOS so that AOS can orchestrate various resources. The AOS.Stack element corresponds to the solution in real scenarios. It can implement one-click deployment of the solution. After being defined, the element can be replicated in batches, helping services to be quickly deployed on the cloud.
