RESEARCH

LABORATORY TEAM

Laboratory for Internet Computing

LINC PEOPLE

LINC focuses its research activities on three important areas of Internet Computing, namely Cloud and Grid computing, Web data management and Vehicular computing.

RESEARCH PROJECTS

CELAR

Automatic, Multi-Grained elasticity Provisioning for the Cloud

The vision of the CELAR project is to provide automatic, multi-grained resource allocation for cloud applications. This enables the commitment of just the right amount of resources based on application demand, performance and requirements, results in optimal use of infrastructure resources and significant reductions in administrative costs.

For more information, visit the website of the project. For UCY activities in CELAR, visit this website

iSocial Marie-Curie ITN

Decentralised Online Social Networks

The iSocial consortium, which consists of 7 full partners and 6 associate partners, envisions the emergence of distributed and scalable overlay networking and distributed storage infrastructures that will provide support for open social networks and for innovative social network applications, preserving end-user privacy and information ownership. The main objective of iSocial is to provide world class training for a next generation of researchers, computer scientists, and Web engineers, emphasizing on a strong combination of advanced understanding in both theoretical and experimental approaches, methodologies and tools that are required to develop Decentralized Online Social Networking platforms. iSocial training network will fund 11 Ph.D. students and 5 post-doctoral fellows. To meet this goal, iSocial is divided into four interconnected research topics, which include important and timely research challenges with a high exploitation potential: i)Overlay Infrastructure for Decentralized Online Social Networking Services; ii)Data storage & distribution; iii)Security, privacy & trust; iv) Modelling and Simulation.

For more information, visit the website of the project.

PaaSport

The PaaS Marketplace

The vision of the PaaSport project is to resolve the application portability issues that exist in the Cloud PaaS market through a flexible and efficient deployment and migration approach. To this end, PaaSport will combine Cloud PaaS technologies with lightweight semantics in order to specify and deliver a thin, non-intrusive Cloud-broker (in the form of a Cloud PaaS Marketplace), to implement the enabling tools and technologies, and to deploy fully operational prototypes and large-scale demonstrators.

For more information, visit the website of the PaaSport - PaaS Interoperability Marketplace project

CAMF

Cloud Application Management Framework

The project aims to develop and sustain the necessary tooling that will assist Cloud application lifecycle management operations, using open standards and languages, where appropriate. As aforementioned, these operations are classified into three distinct categories: (1) application description, (2) application deployment and (3) application monitoring. CAMF will follow the Eclipse OSGi plug-in based software architecture for each of the aforementioned operations and will inherit the same look-and-feel that Eclipse users are accustomed to. To guarantee the quality of the resulting product, the project will follow designated development cycles with rigorous code reviews, unit tests and release cycles.

CAMF has been selected to receive an AWS in Education Research grant for the next two years. The grant will enable the CAMF community to utilise Cloud services from AWS for all facets of development, testing, demo and training.
