That's actually really useful Titus - thanks a lot for sharing this! Last time I had the process with AWS done was last May, so that's why I had the wrong impression. This also means that we probably need to find a working solution for preparing participants for the DC genomics lesson.

Psomopoulos <fp...@issel.ee.auth.gr>; Software Carpentry Discussion <discuss@lists.software-carpentry.org> Subject: Re: [Discuss] AWS cost for genomics lesson Apologies if this is a bit off-topic, but: Note that in recent months (at least the last 4 months or so) you will be blocked from starting up a new AWS instance for at least the first few hours after you first try, until they verify your account. Presumably this is to stop people from creating fake accounts and running up compute before being caught. This puts a serious monkey wrench in any workshop that doesn't have people sign up *and try to start a new instance at least the night before the workshop*. (This change in AWS practice happened sometime around our workshop at Scripps Institute of Oceanograph, https://2016-metagenomics-sio.readthedocs.io/en/latest/, so before October 12, 2016. We had 17 people unable to start their instances. Fun fun fun!) I've talked to some AWS folk about it and so far there has been nothing they could do other than take a list of accounts to prevalidate (which didn't work the one time we tried to do it). Largely for this reason, I'm going to seriously try out JetStream as an alternative to AWS in the next few months. best, --titus On Fri, Jan 27, 2017 at 12:00:23PM -0800, Jaime Ashander wrote: > For the recommended instance type, t2.medium, (per > http://www.datacarpentry.org/genomics-workshop/ ) the current costs in > N VA (per https://aws.amazon.com/ec2/pricing/on-demand/ ): > > t2.medium 2 Variable 4 EBS Only $0.047 per Hour > - Jaime > > On Fri, Jan 27, 2017 at 11:44 AM, Fotis E.
