Personal cloud storage: Usage, performance and impact of terminals

Abstract

Personal cloud storage services such as Dropbox and OneDrive are popular among Internet users. They help in sharing content and backing up data by relying on the cloud to store files. The rise of mobile terminals and the presence of new providers question whether the usage of cloud storage is evolving. This knowledge is essential to understand the workload these services need to handle, their performance, and implications.In this paper we present a comprehensive characterization of personal cloud storage services. Relying on traces collected for one month in an operational network, we show that users of each service present distinct behaviors. Dropbox is now threatened by competitors, with OneDrive and Google Drive reaching large market shares. However, the popularity of the latter services seems to be driven by their integration into Windows and Android. Indeed, around 50% of their users do not produce any workload. Considering performance, providers show distinct trade-offs, with bottlenecks that hardly allow users to fully exploit their access line bandwidth. Finally, usage of cloud services is now ordinary among mobile users, thanks to the automatic backup of pictures and media files.

Análise de um Serviço Virtual de Armazenamento que Explora Classes de Objetos na Nuvem e Padrões de Acesso

“…Em vários trabalhos foram analisados o desempenho e caracterizados o comportamento de usuários em serviços pessoais de armazenamento na nuvem como Dropbox, Onedrive e Google Drive [Bocchi et al 2015, Gracia-Tinedo et al 2016, Gonçalves et al 2016. Os autores desses trabalhos sugerem várias otimizações para um serviço de armazenamento, mais especificamente com o foco em redução de custo com transferências e sincronizações de dados entre a nuvem e dispositivos de usuários em compartilhamentos.…”

Um Estudo Sobre Compartilhamentos entre Contatos via D2D em Serviços de Armazenamento Pessoal em Nuvem

“…A importância de compartilhamentos em serviços de armazenamento na nuvem já foi demonstrada em vários estudos. Medições sobre o Dropbox [Bocchi et al 2015] e UbuntuOne [Gracia-Tinedo et al 2015] mostraram que volumes de downloads superam uploads nesses serviços. Em [Gracia-Tinedo et al 2016] foi mostrado evidências de adoção massiva de compartilhamento de dados e a predominância dos usuários que fazem apenas download de arquivos.…”

On the Cost-Benefit Tradeoffs of Cloud Storage Services for End Users and Service Providers

“…It offers the means for users to easily backup data and perform collaborative work, with files being automatically uploaded, shared and synchronized. Cloud storage is already one of the most popular Internet services [Bocchi et al 2015b]. Well-established players such as Dropbox, Google and Microsoft, face a fierce competition for customers.…”
