DrACO: Discovering available cloud offerings

摘要

Current cloud technologies suffer from a lack of standardisation, with different providers offering similar resources in a different manner. The aim of this work is to contribute overcoming such heterogeneity, by showing how the OASIS TOSCA standard can be exploited to provide a standard-based representation of the virtual machines and platforms offered by IaaS and PaaS cloud providers. We also present DrACO, an open-source prototype tool that permits to look-up for cloud offerings and to retrieve them in a standardised TOSCA format.
