When you deploy an application to the cloud or update a deployed application in the cloud, virtual machines are created and software is provisioned in the virtual machines. During these processes, deployment failures can occur that can affect your deployment.

Failures can occur in several deployment phases. In Application Services, you can identify where failures occurred by viewing the execution plan. You can use the Resume Deployment option, which is available in the Execution Plan panel in the Deployment View, to resume a failed deployment.
