  One of the biggest challenges in the High-Luminosity LHC (HL- LHC) era will
be the significantly increased data size to be recorded and analyzed from the
collisions at the ATLAS and CMS experiments. ServiceX is a software R&D project
in the area of Data Organization, Management and Access of the IRIS- HEP to
investigate new computational models for the HL- LHC era. ServiceX is an
experiment-agnostic service to enable on-demand data delivery specifically
tailored for nearly-interactive vectorized analyses. It is capable of
retrieving data from grid sites, on-the-fly data transformation, and delivering
user-selected data in a variety of different formats. New features will be
presented that make the service ready for public use. An ongoing effort to
integrate ServiceX with a popular statistical analysis framework in ATLAS will
be described with an emphasis of a practical implementation of ServiceX into
the physics analysis pipeline.
