The public cloud services substantially changed the service delivery landscape in the Internet. Web technology allows to deliver application-level functionality in a web browser with ease and flexibility surpassing traditional desktop applications.īoth synchronization and collaboration services are integrated into “cloud storage” environments: Google Docs in an application layer integrated into Google Drive storage, Office 365 is integrated with One Drive storage and Dropbox Paper service is an extension of Dropbox storage. On the other hand, collaboration and teamwork services are usually delivered as web services such as Google Docs, Office 365 and Dropbox Paper. The sync folder is a transparent service endpoint to share and synchronize user’s content. In case of file synchronization, Dropbox successfully created a very simple mechanism to access the service: a local sync folder on a user’s device. Ĭloud computing model also redefined user’s interactions with IT services. Data storage is integrated with transparent use of third-party S3 storage services where appropriate. The backend – a large scale custom software-defined-storage system – is deployed in private, highly-available data centers. Simple user interfaces hide complex and sophisticated service back-ends: Dropbox alone ingests over 1 billion files a day and handles a large variety of user workloads.
In this article we focus on storage services and their direct ecosystem.Ĭloud storage services for end-users are easily accessible in the mass-market because the service front-ends are very well integrated into consumer devices: web clients as well as desktop and mobile environments. The cloud service model applies to all kinds of computing resources and applications: email, metadata queries, computing nodes ( virtual machines), storage services, databases, files, apps and so on. In the next section we will briefly examine this background.Ĭloud services from industry leaders such as Google, Amazon or Dropbox defined a new, ubiquitous service delivery model in IT. The on-premise CS3 services appeared few years ago for use in science and education, in parallel to public cloud storage services which emerged in the Internet for general-purpose use. The CS3 community, brings together users, researchers, developers, technology- and service providers of on-premise cloud services as well as large cloud service companies. This article, and the special section of FGCS journal, is dedicated to emerging cloud synchronization and sharing services (CS3) for Science, Education and Research.
