D3.1 Demonstrator general technical requirements

The Blue-Cloud innovation potential will be explored and unlocked by developing five dedicated Demonstrators as Virtual Labs together with excellent marine researchers. For that purpose, Blue-Cloud selected five varied and domain-coverage rich scientific demonstrators. The objective is to develop and deploy a Virtual Lab for each demonstrator, which will become part of the Blue-Cloud Virtual Research Environment (VRE) and as such will be made accessible for users. The D4Science e- infrastructure will be the core platform for the VRE. This e-infrastructure already holds a generic VRE with many core services for building and running multiple Virtual Labs, dedicated to specific research targets. The D4Science e-infrastructure also has proven solutions for connecting to external computing platforms and means for orchestrating distributed services, which will be instrumental for smart connections to the other e-infrastructures in Blue-Cloud, namely EUDAT and DIAS (WekEO).

This deliverable D3.1 describes and summarizes the technical requirements towards the development and implementation of the Blue-Cloud demonstrators as Virtual Labs. These technical requirements have been derived from communications with the partners who are in charge of the Blue-Cloud Demonstrators. This implicates that the technical requirements are assessed and formulated from their perspective concerning the input, output, and workflow processes that are envisioned for the Demonstrators.

These requirements will be used in the further development of the Virtual Labs, which will take place in a close cooperation between WP3 and WP4, whereby WP4 will focus on the activities for making the existing VRE at D4Science more fit for purpose of the Blue-Cloud Demonstrators, which might involve expanding and/or upgrading functionalities. The technical requirements as summarized in this deliverable D3.1 will also contribute to the identification of the key challenges to address with the design of the overall technical architecture for the Blue-Cloud project.

As a next step in the cooperation and exchanges between WP3 and WP4, the Demonstrator groups will explore the existing VRE at D4Science, which will be supported by Webinars introducing and explaining VRE services. Moreover, the deliverable D3.2 'Demonstrator Implementation guidelines' will be drafted in cooperation with WP4 and from the perspective of the existing D4Science e-infrastructure.
