Alejandro, Maybe this will help you. It's a cost analysis we did for one of our large clients who were using S3 heavily and considering a move to Swift. We did the analysis to determine if it was worth the investment and confirm how the underlying infrastructure (phys/virt) impacted the final cost of service. It was then easy to compare those numbers against AWS so their leadership could assess whether the savings were worth the effort. Because there were definitely savings.
Analysis completed about a month ago. Conclusion? Running Swift on virtual infrastructure wasn't worth it (too expensive), running even a small Swift cluster on physical commodity hardware *beat* AWS by $0.029 (assuming AWS was $0.075 per GB). The margins are slim for both Swift and AWS but saving 2c per GB adds up which means Swift gets more cost advantageous with larger clusters; according to our calculations. Numbers below assume VMware is used for virtual infra with its full-cycle service delivery costs baked in. > *Monthly costs Swift on Virt Swift on Phys AWS **Per GB $0.63 $0.046 > $0.075* > > Proxy ct: 6 $5.04 4GB RAM=$0.84 > Storage ct: 15 $7,887.60 2500gb=$525 4GB RAM=$0.84 > Keystone ct: 3 $3.36 8GB RAM=$1.68 > Virt Cost $7,896.00 monthly > > HW Cost $34,500 Cap ~$1500/server > $575 monthly 5 year EOL > $575 / 12.5TB usable capacity = cost/GB/month *Adam Lawson* AQORN, Inc. 427 North Tatnall Street Ste. 58461 Wilmington, Delaware 19801-2230 Toll-free: (844) 4-AQORN-NOW Direct: +1 (302) 268-6914 On Wed, Apr 30, 2014 at 11:55 AM, Alejandro Comisario < alejandro.comisa...@mercadolibre.com> wrote: > Lovely Johon, i'll read that but hey ... beilieve me, this in-deep > analysis that im going through in my company making a production proyect > crumble just because lack of costs data regarding amazon will be a constant > while amazon keeps droping prices. > > If you can share those details, that would be : project-saving. > Thanks so much. > > > > Alejandro Comisario > *MercadoLibre Cloud Services* > Arias 3751, Piso 7 (C1430CRG) > Ciudad de Buenos Aires - Argentina > Cel: +549(11) 15-3770-1857 > Tel : +54(11) 4640-8443 > > > On Wed, Apr 30, 2014 at 2:37 PM, John Dickinson <m...@not.mn> wrote: > >> Alejandro, >> >> We blogged about this recently at >> https://swiftstack.com/blog/2014/04/24/about-those-public-cloud-price-drops/. >> I've asked around the office here at SwiftStack to see if we can put >> together some more public cost details (specifically in response to you >> question), so I hope we can share some more info soon. >> >> --John >> >> >> >> On Apr 30, 2014, at 5:11 AM, Alejandro Comisario < >> alejandro.comisa...@mercadolibre.com> wrote: >> >> > Hi guys. >> > After amazon dropped its prices among other things, on S3 its seems >> that i need in my compañy to justify/analyze if swift keeps being the most >> cost convenient solution (we have it in house) >> > >> > When we decided going with swift one year ago, one of the main >> constraints was "keeping the data in our datacenter" so we did'nt do the >> excercice of costs, but today since "seems" that this constraint might be >> no more i need to go through this excercise (of course i want to stay with >> swift) >> > >> > So, im reaching the community to ask experiences of people that went >> through the same scenario, things to take into account and recent results. >> > >> > I bumped with a great aticle from Amar Kapadia at: >> http://www.buildcloudstorage.com/2012/01/can-openstack-swift-hit-amazon-s3-like.htmland >> since i belive is a great place to start, the calculations an variables >> might be outdated. >> > >> > help is more than apreciated!! >> > >> > >> > best. >> > alejandrito >> > >> > _______________________________________________ >> > Mailing list: >> http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack >> > Post to : openstack@lists.openstack.org >> > Unsubscribe : >> http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack >> >> > > _______________________________________________ > Mailing list: > http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack > Post to : openstack@lists.openstack.org > Unsubscribe : > http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack > >
