Project : Union Pacific Railroad CES/AMA Migration Project April 2019 to May 2021

Description:

AMA(Accessorial management Application) and CES(Chargeable event systems) are the two billing systems in Union pacific railroad application which take care of customer tariff billing. These two systems are written over a JMS service and listen to the events generated by a system called TCS. Union pacific came up with another events system by name NEQ inplace of TCS. AMA and CES are being migrated with new technologies so that new event system called NEQ feeds the data instead of TCS. Both AMA and CES are close to monolith architecture applications.
