Data analytics is one of the main cornerstones in many enterprise architectures and the data lake paradigm is more and more adopted to assist organizations in taking reliable, accurate, and fast decisions. Although the initial approaches to address these issues saw data lakes as the evolution of data warehouses, implemented on-premises, cloud providers are nowadays including in their offerings platforms to set up and run them. Nevertheless, the increasing amount of data generated at the edge and the need to enable data sharing among organizations are posing new challenges in terms of performance, energy efficiency, and privacy/confidentiality, which can be properly addressed with data lakes that are deployed along the whole computing continuum as well as building a federation of such data lakes.

The ambition of TEADAL – Trustworthy, Energy-Aware federated DAta Lakes along the computing continuum is to provide key cornerstone technologies to create stretched data lakes spanning the cloud-edge continuum and multi-cloud, providing privacy, confidentiality, and energy-efficient data management. The TEADAL data lake technologies will enable trusted, verifiable and energy-efficient data flows, both in a stretched data lake and across a trustworthy mediatorless federation of them, based on a shared approach for defining, enforcing, and tracking privacy/confidentiality requirements balanced with the need for energy reduction.

To realize its ambitious vision, TEADAL leverages on relevant actors in the cloud and big data EU scene, ranging from top research institutions (POLIMI, TUB, TUW), big companies (IBM, ALMAVIVA), research centers (CEFRIEL, I2CAT), innovative SMEs (CYB, UW, MARTEL) with direct liaisons with the most influencing active initiatives at the EU level concerning the privacy/confidentiality-aware data sharing (GAIA-X, IDSA, and ECSO). With the ambition of covering most of the European Common Data Spaces in a coherent approach, TEADAL includes pilot case providers, ranging from big financial institutions (ING), healthcare actors (MARINA), local transportation companies (AMT), regulators (UITP), manufacturing (ERT), public administration (RT), agricultural (TERRAVIEW), and energy related (BOX2M) companies.
