Here's my spending back in Feb. I am also in the free tier, BTW.<br>
<br>
In that month, I used 27 hours of t1.micro & 1 hour of m1.small, thus<br>
I got charged $ 0.09 ($0.085 rounded up!).<br>
<br>
Amazon EC2 running Linux/UNIX<br>
$0.00 per Micro Instance (t1.micro) instance-hour (or partial<br>
hour) under monthly free tier 27 Hrs 0.00<br>
$0.085 per Small Instance (m1.small) instance-hour (or partial<br>
hour) 1 Hr 0.09<br>
<br>
Amazon EC2 EBS<br>
$0.00 per GB-month of provisioned storage under monthly free<br>
tier 0.398 GB-Mo 0.00<br>
$0.00 per 1 million I/O requests under monthly free tier 428,595 IOs 0.00<br>
<br>
Elastic IP Addresses<br>
$0.00 per Elastic IP address remap - first 100 remaps / month 1<br>
Count 0.00<br>
<br>
<br>
I am under the free EBS limit (it was then 10GB month, but the limit<br>
got bumped up to 30 GB month recently). Note that you can use 60GB for<br>
15 days, then 0 GB for the rest of the month, and Amazon will not<br>
charge you anything. I think Amazon has a very straightforward<br>
pricing, and you don't need to worry about whether the EBS is used by<br>
a t1.micro or a cg1.4xlarge or even just left there for backup...<br>
<br>
Basically, feel free to mix and match free & non-free EC2 resource.<br>
