EC2 Billing

[Peter Cawthron]

I'm still very confused by EC2 billing but I have realised something. This is billing for 5 December requested in 24-hour granularity:

AmazonEC2,RunInstances,BoxUsage:t1.micro,,12/05/12 00:00:00,12/06/12 00:00:00,24

AmazonEC2,EBS:IO-Read,EBS:VolumeIOUsage,,12/05/12 00:00:00,12/06/12 00:00:00,1138556

AmazonEC2,EBS:IO-Write,EBS:VolumeIOUsage,,12/05/12 00:00:00,12/06/12 00:00:00,54997

AmazonEC2,CreateVolume,EBS:VolumeUsage,,12/05/12 00:00:00,12/06/12 00:00:00,206158430208

AmazonEC2,RunInstances,DataTransfer-Out-Bytes,,12/05/12 00:00:00,12/06/12 00:00:00,10665877

AmazonEC2,RunInstances,DataTransfer-In-Bytes,,12/05/12 00:00:00,12/06/12 00:00:00,5807251

AmazonEC2,PublicIP-In,DataTransfer-Regional-Bytes,,12/05/12 00:00:00,12/06/12 00:00:00,581

AmazonEC2,PublicIP-Out,DataTransfer-Regional-Bytes,,12/05/12 00:00:00,12/06/12 00:00:00,905

AmazonEC2,AssociateAddress,ElasticIP:Remap,,12/05/12 00:00:00,12/06/12 00:00:00,1

The 206Gb has been troubling me. Until you look at the report in 1-hour granularity for the first hour of 5 December:

AmazonEC2,RunInstances,BoxUsage:t1.micro,,12/05/12 00:00:00,12/05/12 01:00:00,1

AmazonEC2,EBS:IO-Read,EBS:VolumeIOUsage,,12/05/12 00:00:00,12/05/12 01:00:00,473

AmazonEC2,EBS:IO-Write,EBS:VolumeIOUsage,,12/05/12 00:00:00,12/05/12 01:00:00,3376

AmazonEC2,CreateVolume,EBS:VolumeUsage,,12/05/12 00:00:00,12/05/12 01:00:00,8589934592

AmazonEC2,RunInstances,DataTransfer-Out-Bytes,,12/05/12 00:00:00,12/05/12 01:00:00,688880

AmazonEC2,RunInstances,DataTransfer-In-Bytes,,12/05/12 00:00:00,12/05/12 01:00:00,262691

So know we see our 8Gb instance. I would expect school children to do this sort of thing in the first program they ever write! Clue: 25 * 8 = 200)
