“…• A novel model to analyze cost-benefit tradeoffs of service policies in various scenarios, specifically, to identify whether and when a win-win solution that meets the interests of provider and users can be achieved. These contributions were presented in two conference papers [Gonçalves et al 2016, Gonçalves et al 2017.…”

Cloud Storage is a very popular Internet service. It allows users to backup data to the cloud as well as to perform collaborative work while sharing content. Despite the increasing interest in cloud storage, a thorough investigation on the costs and beneﬁts of this service for providers and end users has not been conducted yet. This dissertation aims at investigating such cost-beneﬁt tradeoffs for both providers and end users jointly. Using data collected from a real service (Dropbox), we developed new models, methodologies and tools to support providers and users in improving jointly their beneﬁts in cloud storage.

“…The goal of these policies is to enable device synchronization without the need to retrieve content from the cloud. 6 We start by presenting our general approach to design such policies and how our general model can be used to estimate the improvements achieved by any such policy (Section IV-A). We then introduce the design principles of two specific policies (Sections IV-B and IV-C).…”

Personal Cloud Storage (PCS) is a very popular Internet service. It allows users to backup data to the cloud as well as to perform collaborative work while sharing content. Notably, content sharing is a key feature for PCS users. It however comes with extra costs for service providers, as shared files must be synchronized to multiple user devices, generating more downloads from cloud servers. Despite the increasing interest in this type of service, a thorough investigation on the costs and benefits of PCS for service providers and end users has not been conducted yet. To that end, we propose a model to analyze cost-benefit tradeoffs for both parties. We develop utility functions that capture, in an abstract level, the satisfaction of the service provider and users in various scenarios. Then, we apply our model to evaluate alternative policies for content sharing in PCS. We consider two alternative policies for the current PCS sharing architecture, which count on user collaboration to reduce providers' costs. Our results show that such policies are advantageous for providers and users, leading to 77% utility improvements for both parties, while requiring low commitment of resources from participating users. 1
