cloud instance comparision

Today tried the main cloud instance, it's amazed to see how they are so powerful and easy to use, definitely it's the future trend.
Amazon EC2
    Easily to use for linux and windows instance, free for one year, cannot run AutoIt script over GUI unless the desktop is showed
Windows Azure
    Complex to use, and the fee calculation is complex
Google Cloud
   Easy to use, free for one year with 300USD credit, powerful, can install VirtualBox and use it like a local desktop. Super fast to move files to Google drive. (1 min to upload VirtualBox image to the google drive).
   The problem for google cloud is that after I installed WinXP on the VirtualBox (nested virtualization), the scheduler by Java has some delay (scheduler to run at 9:21 but begin to run at 9:25 or 9:26), after the WinXP often has a blue screen issue.

update: for the blue screen issue, can be fix by deleting the intelppm.sys:
1. start with the safety mode
2. search intelppm.sys under c:\windows
3. delete the file from the command line (no need to delete the file under "driver cache" *.cab)
