Euclid is an ESA mission to explore the dark Universe. Euclid will map the 3D distribution of up to two billion galaxies and dark matter associated with them. It will hence measure the large-scale structures of the Universe across 10 billion light years, revealing the history of its expansion and the growth of structures during the last three-quarters of its history. In total Euclid will produce up to 26 PB per year of observations. The Euclid Archive System is a joint development between ESA and the Euclid Consortium and is led by the Science Data Centres of the Netherlands and the ESDC (ESAC Science Data Centre). The EAS is composed by three different subsystems: Data Processing System (DPS), Distributed Storage System (DSS) and Science Archive System (SAS). The SAS is being built at the ESDC and is intended to provide access to the most valuable scientific data, which is currently estimated in 10 PB of images, catalogues and spectra, after 6 years mission.

Nowadays, the Astronomy science is inherently interoperable from science data and models perspective but also from the tools and interfaces to exploit them. In this respect, the International Virtual Observatory Alliance, is the organization whose main mission pursues for the data interoperability in Astronomy in which the Euclid Archive has been part of from an early stage. The Euclid Archive was designed to provide interoperability capabilities to enable scientific discoveries on science: images, spectra and a major catalogue of 10 Billion sources. In this paper we will describe how Euclid, supported by its successful precursor Gaia, will make use of the most remarkable IVOA standards (TAP, ObsCore, ConeSearch, SIA, SSA, SODA, VOSpace, DataLink) but also how VO standars are part of the Scientific Platforms ecosystem enabling scientific discoveries to the community.
