Get two free computers for a year!
 

Hey all... I'm not sure if this is a good idea or not. But what the heck...

I'm at the stage with my project where I need some BIG iron. But only occasionally. I decided it was time to start learning how to leverage Amazon's EC2.

I went to sign up, and discovered that for new customers they're offering a year's worth of "t1.micro" Linux instances AND a year's worth of Windows instances for free! All you need is a valid credit card -- they won't bill it unless you have "overage".

Details are at [URL="http://aws.amazon.com/free/faqs/"]http://aws.amazon.com/free/faqs/[/URL].

The virtual machine provided isn't too powerful (and its performance jumps around a bit, as one would expect), but it's definitely not a 386 either... And it's free!

Certainly enough to clear a few DCs, LLs or P-1s in a year.... :smile:

Very interesting. Thanks!

It's awesome! Thanks for sharing!

Almost identical values in benchmark.
Fairly nice (even if a bit old, this series was launched in 2007), and, indeed, free!

We don't look a Trojan horse in the mouth, do we?

750 hours is just a little over a month. Or am I reading it wrong?

But, thanks for sharing in any way. Nice find.

24 * 31 == 744.

[QUOTE=chalsall;328198]24 * 31 == 744.[/QUOTE]

I mean, it is not anywhere close to a year; only 750 hours are free. Or not?

You didn't read the Terms...

You get 750 hours per [B][I][U]month[/U][/I][/B] for a [B][I][U]year[/U][/I][/B].

Sadly, it appears English is as scary as Math.

Just introduce Latin, and the masses will be running scared towards to the Super Bowl....

Thank you for answering my question. The terms, as posted on the amazon web site, were unclear to me.

:max:

Now the physics question: how fast does the server need to move relative to the observer so that the when the observer counts 744 hours on his or her watch, 750 hours had passed on the server. LOL
