The DSA (Distributed Systems Architecture) Research Group at Complutense University of Madrid conducts research in advanced distributed computing and virtualization technologies for large-scale infrastructures and resource provisioning platforms.

Ongoing research lines address the challenges of Infrastructure-as-a-Service (IaaS) Cloud Computing:

Cloud architectures
Energy-efficient cloud computing
Cloud federation and interoperability
High Performance Computing (HPC) clouds

DSA-Research group leads the OpenNebula Cloud Toolkit, widely used open-source technology to build cloud infrastructures; is a co-founder of the OGF Working Group on Cloud Computing Interface; and participates in the main European projects in cloud computing, such as RESERVOIR, flagship of European research initiatives in virtualized infrastructures and cloud computing, BonFIRE, 4CaaSt and StratusLab. The results of the research have been published in several leading publications on virtualization and cloud computing, and members of the group participate in the Program Committee of the most important workshops and conference in the research field. The group is currently coordinating the Spanish Initiative in Grid Middleware and the Working Group on SOI and Grids of INES - Spanish Technology Platform on Software and Services; and is involved in NESSI.
