BizTalk suffered to take the load (lots of messages in and out) compared to IBM's WebSphere Message Broker. BizTalk was used as a B2B integration tool within an integration project, where seven or more organizations had to communicate with each other within the “Integrated Justice System” for criminal cases, from case registration to legal aid, case closure, punishments, community service, and so on. The other organizations used Message Broker and NPA used BizTalk. Thus, compared to the transmission and load capacity, BizTalk stood second.
