VMware vCloud Air is the public cloud offer by VMware (formally known as vCloud Hybrid Service) built on the foundation of vSphere and compatible with your on-premises VMware’s based data center. Actually it included several different services: infrastructure, disaster recovery, and various applications as service.
For the IaaS services there are: Dedicated Cloud, Virtual Private Cloud, Virtual Private Cloud OnDemand. For the availability services there are: Disaster Recovery and Data Protection.
I’m spending some time by testing the Virtual Private Cloud OnDemand service, with a limited time $500 service credit offer. If you are also interested there is a promotion to get $300 in service credit for your first 90 days. The limit (as also in my case) is that this will permit only to test the IaaS service and not the others.
