• TMS (Terminal Management System) is used to manage a very large number of payment terminals (300k+), it gives users a uniform way to manage different terminals from different hardware vendors. TMS has a complex architecture, consisting of two components TMS (1 WildFly instance) providing GUI and implementing some business functions and RTMS (3 Spring-boot instances) implementing most of the business functionalities. A gradual migration from TMS to RTMS is being carried out. The system intensively uses Spring, Hibernate and RabbitMQ. The system has distributed transactions (different two-phase-commit, saga approaches) and distributed cache (Hazelcast). TMS is integrated with many internal and external systems (via REST, SOAP, RMI, direct database connections and database links). The GUI is written in GWT and GWTExt.
