The exponential increase of the data volume generated by state of the art astrophysical instruments like ALMA ~1PB/year, MWA ~ 3PB/year or LOFAR ~ 6PB/year, as well as the forthcoming SKA1 ~ 100PB/year, is changing the way in which astronomers access and share the data. The trend is that astronomers make use of Distributed Computing Infrastructures (DCIs) like e.g. Grid or Cloud, for accessing and analysing the generated data. AMIGA aims to contribute to an efficient exploitation of these DCIs. For this, some of its developments explore ways for optimizing the use of the resources from these infrastructures by lowering the technical barriers that their use implies.
