Recently, fields with substantial computing requirements
have turned to cloud computing for economical, scalable, and on-demand
provisioning of required execution environments. However, current cloud
offerings focus on providing individual servers while tasks such as application
distribution and data preparation are left to cloud users. This article presents a
new form of cloud called HPC Hybrid Deakin (H2D) cloud; an experimental
hybrid cloud capable of utilising both local and remote computational services
for large embarrassingly parallel applications. As well as supporting execution,
H2D also provides a new service, called DataVault, that provides transparent
data management services so all cloud-hosted clusters have required datasets
before commencing execution.
