as said in the previous post I'm taking my first day time to do HOL: for the others who want to do it I advice to have your own device and avoid the long queue at the HOL stand. So BYOD is always the vest solution.
I've just completed HOL-SDC-1426 - vCloudAir Introduction.
it's a four module HOL and it's quite long but really interesting.
vCloud Air is a secure Infrastructure as a Service (IaaS) cloud owned and operated by VMware, and it's the new name for the product named vCHS (vCheese). It is built on the trusted foundation of vSphere and and is ideally suited for running existing Enterprise workloads as well as new applications. With vCloud Air, IT administrators and architects now have a common platform for seamlessly extending existing data centers to the cloud, leveraging the same tools and processes they use today to manage their on premises environments.
Each cloud instance type includes utilizes the Virtual Datacenter (vDC) construct. In a Dedicated Cloud a customer could have multiple virtual datacenters (vDC) with each vDC owning a subset of the global resources. In the case of a Virtual Private Cloud a customer only has access to 1 vDC. It is via this vDC construct that VMs are deployed and managed.
