Supported regions indicates the regions where OOS can be deployed. By default, OOS deployed in a region can only be used to manage resources in the same region. For example, OOS deployed in China (Hangzhou) can only be used to manage ECS instances in this region. However, OOS provides a method to manage resources deployed in other regions. You can specify the RegionID parameter in the ACS::ExecuteAPI action to call API operations in other regions. We do not recommend that you use this method.
