Custom format for displaying bytes as kb, mb, gb or tb.
Response to a few places on the internet: https://productforums.google.com/forum/#!topic/docs/x_T_N-yRUYg And here: https://stackoverflow.com/questions/1533811/how-can-i-format-bytes-a-cell-in-excel-as-kb-mb-gb-etc

Sometimes you want to retrieve EC2 insntances' region information.
You can query that information through instance metadata(169.254.169.254).
$ curl --silent http://169.254.169.254/latest/dynamic/instance-identity/document
{
"privateIp" : "172.31.2.15",
"instanceId" : "i-12341ee8",
"billingProducts" : null,
"instanceType" : "t2.small",
