RESEARCH DESCRIPTION
----------------------
Cloud Computing is a paradigm for enabling remote, on-demand access to a
set of configurable computing resources. A Cloud may stand at different
levels of the hardware and software stack where: (i) an Infrastructure as
a Service (IaaS) cloud enables access to hardware resources such as
servers and storage devices, (ii) a Platform as a Service (PaaS) cloud
allows the access to software resources such as operating systems and
software development environment, and (iii) a Software as a Service (SaaS)
cloud is an alternative to classical software applications running locally
on personal computers which are, instead, provided remotely by the cloud
(e.g. messaging services, document editing services, etc.). Although Cloud
Computing provides a means to support remote, on-demand access to
computing resources, its ad-hoc management poses significant challenges to
the scalability, performance, dependability and economical costs of cloud
services.
The proposed project aims at investigating novel protocols to enhance the
scalability and performance of the cloud, while guaranteeing its
dependability and reducing its cost. Caching is a classical technique to
improve service performance [Bouchenak et. al. 2006, Perez et. al. 2007,
Rabinovich et. al. 2001]. However, service composition and cloud
elasticity that underly Cloud Computing make classical caching techniques
sub-optimal.
This project aims at: (i) Proposing novel distributed algorithms and
protocols, for (ii) Managing caching in th cloud, and (iii) Handling
scalability and data integrity issues.

This project is a joint work between INRIA, Grenoble, France, and the
Technical University of Madrid, Spain.
