Cloud computing infrastructures provide a way for researchers to source the computational and storage resources\r\nthey require to conduct their work and to collaborate within distributed research teams. We provide an overview of a\r\ncloud-based elastic virtual infrastructure for research applications that we have established to provide researchers with a\r\ncollaborative research environment that automatically allocates cloud resources as required. We describe how we\r\nhave used this infrastructure to support research on the Sun�s corona and how the elasticity provided by cloud\r\ninfrastructures can be leveraged to provide high-throughput computing resources using a set of off-the-shelf\r\ntechnologies and a small number of additional tools that are simple to deploy and use. The resulting infrastructure\r\nhas a number of advantages for the researchers compared to traditional clusters or grid computing environments that\r\nwe discuss in the conclusions.
