<div dir="ltr">Alejandro,<div><br></div><div>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.</div>
<div><br></div><div>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 <i>beat</i> 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.<div>

Alejandro,<br>
<br>
We blogged about this recently at <a href="https://swiftstack.com/blog/2014/04/24/about-those-public-cloud-price-drops/" target="_blank">https://swiftstack.com/blog/2014/04/24/about-those-public-cloud-price-drops/</a>. 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.<br>
