DrACO: Discovering available cloud offerings

  • Special Issue Paper
  • Published:
Computer Science - Research and Development

Abstract

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.

Notes

  1. A more detailed, self-contained introduction to TOSCA can be found in [9].

  2. The YAML file containing all TOSCA type definitions exploited throughout this section is available online at https://raw.githubusercontent.com/di-unipi-socc/DrACO/master/discoverer-gui/public/definitions/draco-types.tosca.

  3. Location policies for TOSCA were first defined by Waizenegger et al. [23]. We hereby adapt them to the TOSCA Simple Profile in YAML.

  4. If no version is specified, this means that all versions of a software distribution/storage system are supported.

  5. Source code publicly available at https://github.com/di-unipi-socc/DrACO.

  6. http://www.dropwizard.io/.

  7. The GUI is publicly available at http://seaclouds.di.unipi.it/draco.html.

  8. The deployment of TOSCA-based applications over IaaS and/or PaaS offerings automatically discovered by DrACO has been successfully experimented in the scope of the SeaClouds project [3].
