It was really easy.
Just click here:
I clicked on the Free Trial.
It knew who I was and pre-populated some fields.
You do have to enter your real phone number and have it send you a text message.
Enter the # and you are prompted to enter your real Credit Card info.
I did. Then accept the terms and conditions and instantly your account is created.
I'm eager to get started, perhaps create a Database online, connect to it with SQL Reporting Services and maybe even spin up an HDInsight cluster. Or maybe create a sample web site, create an online VM, who knows. The possibilities are endless.
How simple was that?
