whoaa i think free credit from trial beside MSDN-subs is the same way to do that.. but is still work?
Yes, in principle it works the same. However, azure is very quick to ban people who are using the free credits from trial-accounts. Also, what will you do after the trial runs out? There's just no long term perspective.
What i mean to say is: Just having fun with a single trial account is probably OK. But if you find yourself planning to sign up for more and more trial-accounts just to abuse the free credits, you are going too far.
