	The Atacama Large Millimeter /sub millimeter Array (ALMA) has entered into operation phase since 2014.

The Atacama Large Millimeter /sub millimeter Array (ALMA) has entered into operation phase since 2014. This transition changed the priorities within the observatory, in which, most of the available time will be dedicated to science observations at the expense of technical time that software testing used to have available in abundance. The scarcity of the technical time surfaces one of the weakest points in the existent infrastructure available for software testing: the simulation environment of the ALMA software. The existent simulation focuses on the functionality aspect but not on the real operation scenarios with all the antennas. Therefore, scalability and performance problems introduced by new features or hidden in the current accepted software cannot be verified until the actual problem explodes during operation. Therefore, it was planned to design and implement a new simulation environment, which must be comparable, or at least, be representative of the production environment. In this paper we will review experiences gained and lessons learnt during the design and implementation of the new simulated environment.
