I am currently studying toward gaining the MCITP Virtualization Administrator certification of which the 70-699 is a required exam. Below are a couple of links that will give you some good preparation material for studying toward the certification:

Hands on testing is always the best way of learning but this will at least give you a good start point if you are new to the technology. Also worth remembering that virtualisation is a big part of cloud solutions.

I have managed to get hold of a public beta account for the new cloud offering from Microsoft Office 365. I just wanted to know how big the content databases could get.
I came across this Microsoft Download in my RSS feeds:
http://www.microsoft.com/downloads/en/details.aspx?FamilyID=6c6ecc6c-64f5-490a-bca3-8835c9a4a2ea
This gives you all the info on Office 365 beta that you need if you want more detail, but for quick reference, here is the breakdown for SharePoint databases:
Initial Storage = 10GB + 500MB per user
Site Collection Storage = Min is 24MB – Max is up to 100GB
Total for any company = 5TB
In answer to one of the questions that I had, yes additional storage, incremented in GB, can be bought for around £2.50 which is charged at a month by month basis.
Hope this helps.

Microsoft have recently announced the “Microsoft Virtual Academy” which is offering self paced training right through from planning, building and managing a private cloud to the new cloud technologies that are available with Windows Azure.
It is really easy to get setup and can give the IT professional some essential skills to become the cloud computing specialist in your organisation. There are currently four modules that you can take:
1) Planning, Building and Managing a Private Cloud
2) Introduction to Windows Azure
3) Windows Azure Security Overview
4) Introduction to SQL Azure
I have already gone through the first module and found it to answer many of the questions that I had about the cloud.
