Google launched their new cloud platform recently and are offering $300 free credit to anyone who signs up.
Free Trial
Here's what you really need to know:
"If you upgrade to a paid account before the 60-day trial period ends, any remaining portion of your initial $300 credit remains in your account until the regular 60 day period is normally up."
"To protect your account from inadvertently accruing charges, when the free trial ends, your account is suspended."
It's great.
