Warning: This deployment has at least one role with only one instance. We recommend that you deploy at least two
instances per role to ensure high availability in case one of the instances becomes unavailable. Doing so also enables coverage of the Windows Azure
Compute SLA (https://go.microsoft.com/fwlink/?LinkID=159704&clcid=0x409), which guarantees 99.95% uptime. For more information please visit here
(https://go.microsoft.com/fwlink/?LinkID=202707).  Find more solutions in the Windows Azure support forum (https://go.microsoft.com/fwlink/?LinkID=206235).
