In 2011, a new agency, EU-LISA, was created in the Area of Freedom, Security and Justice (AFSJ) to manage largescale IT systems. From then onwards, the agency has been responsible for the communication infrastructure of SIS II, VIS and Eurodac, without merging those databases. Due to its short time in operation, it is difficult to assess the effectiveness of EU-LISA, but this paper aims to give an overview of the agency to facilitate knowledge about it.
