At this step, you select one of the templates available for execution in the selected project/region. Select the Run instance template to run a new instance in Cloud. Select any other template to use a previously uploaded stack template. This can result into creation of a number of new resources or other changes in your infrastructure.
Select one of the other stacks to perform the actions prescribed by it. Typically, the custom stack name includes the short information about its purpose. However, please, be attentive when selecting the stack to execute in order to avoid unexpected influence on your resources.
