Europeana Cloud is a Best Practice Network, coordinated by The European Library, designed to establish a cloud-based system for Europeana and its aggregators.
Lasting from 2013 to 2015, Europeana Cloud will provide new content, new metadata, a new linked storage system, new tools and services for researchers and a new platform - Europeana Research. Content providers and aggregators across the European information landscape urgently need a cheaper, more sustainable infrastructure that is capable of storing both metadata and content.

The infrastructure of the project is developed jointly by The Poznań Supercomputing and Networking Center, The European Library, and The Europeana Foundation.
Deliverable 2.2 of the project provides technical specification of the infrastructure along with the requirement gathering process. The recent version of the deliverable is available here.
