Gaia was launched last 19 December 2013 and it will produce in a short term one of the biggest and more complete source catalogues in astronomy. That represents a challenge on different areas: validation, big data management, comparison with other catalogues and the effort to create relevant web services to make accessible this information to the astronomers in an efficient way. We present the current status of the Gaia Archive implementation, including the TAP+ interface, crossmatch capabilities, full catalogue operations like, e.g. full sky histograms generation and the future plans ongoing to be prepared for the Gaia catalogue distribution in 2015. Also, we present the workflow followed to share data and services with all the different groups inside the Gaia Consortium, one of the biggest cooperation projects in astronomy, in order to interface with the main Gaia Archive at ESAC (European Space Astronomy Centre) and how the data will be propagated to the different main data centres across Europe.
