Several solutions offered by different companies attract more and more people. However, little is known about each service capabilities, architecture and – most of all – performance implications of design choices. This paper presents a methodology to study cloud storage services. We apply our methodology to compare 5 popular offers, revealing different system architectures and capabilities. The implications on performance of different designs are assessed executing a series of benchmarks. Our results show no clear winner, with all services suffering from some limitations or having potential for improvement. In some scenarios, the upload of the same file set can take seven times more, wasting twice as much capacity. Our methodology and results are useful thus as both benchmark and guideline for system design.&lt;/p&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>47</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Idilio Drago</style></author><author><style face="normal" font="default" size="100%">Marco Mellia</style></author><author><style face="normal" font="default" size="100%">Maurizio M Munafo'</style></author><author><style face="normal" font="default" size="100%">Anna Sperotto</style></author><author><style face="normal" font="default" size="100%">Ramin Sadre</style></author><author><style face="normal" font="default" size="100%">Aiko Pras</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Inside Dropbox: Understanding Personal Cloud Storage Services</style></title><secondary-title><style face="normal" font="default" size="100%">Internet Measurement Conference - IMC</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Dropbox</style></keyword><keyword><style  face="normal" font="default" size="100%">passive measurement</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2012</style></year><pub-dates><date><style  face="normal" font="default" size="100%">11/2012</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://dl.acm.org/citation.cfm?id=2398776.2398827&amp;coll=DL&amp;dl=GUIDE&amp;CFID=225051145&amp;CFTOKEN=42401286</style></url></web-urls></urls><publisher><style face="normal" font="default" size="100%">ACM</style></publisher><pub-location><style face="normal" font="default" size="100%">Boston, MA</style></pub-location><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;div class=&quot;page&quot; title=&quot;Page 1&quot;&gt;&lt;div class=&quot;layoutArea&quot;&gt;&lt;div class=&quot;column&quot;&gt;&lt;p&gt;&lt;span&gt;Personal cloud storage services are gaining popularity. With a rush of providers to enter the market and an increasing of- fer of cheap storage space, it is to be expected that cloud storage will soon generate a high amount of Internet traffic. Very little is known about the architecture and the perfor- mance of such systems, and the workload they have to face. This understanding is essential for designing efficient cloud storage systems and predicting their impact on the network. &lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span&gt;This paper presents a characterization of Dropbox, the leading solution in personal cloud storage in our datasets. By means of passive measurements, we analyze data from four vantage points in Europe, collected during 42 consecu- tive days. Our contributions are threefold: Firstly, we are the first to study Dropbox, which we show to be the most widely-used cloud storage system, already accounting for a volume equivalent to around one third of the YouTube traffic at campus networks on some days. Secondly, we character- ize the workload users in different environments generate to the system, highlighting how this reflects on network traf- fic. Lastly, our results show possible performance bottle- necks caused by both the current system architecture and the storage protocol. This is exacerbated for users connected far from storage data-centers. &lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span&gt;All measurements used in our analyses are publicly avail- able in anonymized form at the SimpleWeb trace repository: &lt;/span&gt;&lt;span&gt;&lt;a href=&quot;http://traces.simpleweb.org/dropbox/&quot; title=&quot;Linkification: http://traces.simpleweb.org/dropbox/&quot; class=&quot;linkification-ext&quot; style=&quot;color: #006620;&quot;&gt;http://traces.simpleweb.org/dropbox/&lt;/a&gt;&amp;nbsp;&lt;/span&gt;&lt;/p&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</style></abstract></record></records></xml>
