Resources for Cloud Computing Certifications

Hey Tek,

I have an associates in Computer Networking and the CompTIA A+, Net+ and Sec+. I'm trying to get a job with a company that prefers (doesn't require) some Cloud computing background. To give me the best possibility of grabbing one of these positions when they open up the hiring for the data center next year I'm wanting to get a cloud computing cert from CompTIA. What are some good resources to study up on this?
