The Broker@Cloud team presented a day-long tutorial at the 4th European Conference on Service-Oriented and Cloud Computing (ESOCC 2015), held in Taormina (Messina), Italy. The conference was held 15-17 September 2015. We presented the project briefly on the first day, as part of the European Projects track. On the final day, we ran a day-long tutorial, with a mixture of presentations and hands-on experience with the various mechanisms for quality assurance in Cloud service brokerage that have been developed by the partners in the project. The tutorial was attended by about 25 people and several of these participated in the hands-on sessions, filling out broker policies and service descriptions from templates.
Each of the Broker@Cloud mechanisms was presented. These included the Service Description and Broker Policy Editor, the Service Completeness and Compliance checking mechanism, the Failure Prevention and Recovery mechanism, the Verification and Testing Tool Suite and the Preference-based Cloud Service Recommender. Singular Logic ran a version of Elastic Orbi with the case-study example and we were able to witness the installation of services with descriptions that were tested against broker policies. The service was put under stress deliberately to trigger the behaviour of the failure prevention mechanism. Separately, we also generated tests for a REST implementation of a service.
