Conduct cost analysis on AWS services

[jshinm]

In an effort to reduce monthly cost of AWS services, @jovo inquired cost assessment on global AWS services across all 8 accounts we own.

After AWS cost assessment, @jovo instructed major S3 cost reduction by deactivating buckets that are already hosted on BossDB. Tommy will help Jong with validation and verification after which the cost improvement report will be delivered to @jovo

We should look at the various accounts we have to identify how much each costs, and what each is used for.

I suspect that the BossDB idea may not be fruitful as that mostly applies to openneurdata stuff, which we (I believe) don't pay for. However we should verify if this is the case.
