AWS CLI Profiles

Use named profiles if you have to connect using more than one set of credencials. No more editing .aws_config http://docs.aws.amazon.com/cli/latest/userguide/cli-chap-getting-started.html#cli-multiple-profiles

(sub tip: don't set a default and thus never accidentally conenct to the wrong place) aws --profile=prod ec2

Monitoring S3

There is no CloudWatch integration with S3. Roll you own by bolting together readin S3 and pushing it into CloudWatch (or other monitoring tools). Use awk to slice out the columns you are interested in.

For example: track the total size of the bucket in gigs.

aws --profile=prod s3 ls s3://mybucket > /tmp/s3.tmp
TOTALBYTES=`cat /tmp/one.tmp | awk '{print $3}' | paste -sd+ - | bc`
echo "scale=2;${TOTALBYTES}/1000000000" | bc >> ${1}.totalGigs
