Cloud Computing for Research: A Comparison of Data Storage Services

James Gallagher1


Cloud computing represents a collection of different technologies that offer great promise but with sprawling features and documentation that can test one’s patience. In this lecture we will examine some common ‘cloud computing myths’ and two kinds of commonly used cloud data stores – attachable, shareable file systems and web object stores. Different implementations from four cloud vendors (Amazon, Google, MicroSoft Azure, and OpenStack) will be compared. In addition, for web object stores, the increase in data throughput achieved by several optimisation strategies will be examined.

James is one of the developers of the Data Access Protocol (DAP) protocol and is a co-founder of  OPeNDAP. Before that he worked on the Distributed Oceanographic Data System (DODS) project, along with Peter Cornillon, Glenn Flierl and George Milkowski. The DODS project developed the initial versions of the DAP and it’s core software implementation. He assumed the role of OPeNDAP President in 2015.


AeRO is the industry association focused on eResearch in Australasia. We play a critical coordination role for our members, who are actively transforming research via Information Technology. Organisations join AeRO to advance their own capabilities and services, to collaborate and to network with peers. AeRO believes researchers and the sector significantly benefit from greater communication, coordination and sharing among the increasingly different and evolving service providers.
