Microsoft currently offering a Windows Azure platform 30 day pass, so you can try Windows Azure and SQL Azure for free.
"Due to high demand, your access may be delayed and you may be asked to sign up for our wait list."
"Windows Azure and SQL Azure enable you to build, host and scale applications in Microsoft datacenters. They require no up-front expenses, no long term commitment, and enable you to pay only for the resources you use."
