I understand that Pega has capabilities to integrate with external systems by a variety of technologies and standards such as, SOAP, HTTP, EJB, DotNet, SQL, Email, Java, JMS, MQ etc. When it comes to legacy "Mainframe" system at a large enterprise, are these integration method still applicable? I assume Mainframe is nothing like J2EE compliant, so there is no way to have such modern interfaces of SOAP or Java based technologies? Or if they introduce something called "ESB" between Mainframe and PRPC we can use standard integration method listed above? (I don't know much about this "ESB" thing)
I am just trying to connect the keywords around integration I know and "Mainframe".
1. Is this "HostBridge" considered so called ESB? The brochure about HostBridge is really old (2007, see below) and there is not much information out there. Is this commonly used with PRPC? Does it work with PRPC 7x? I need to be sure this works before I recommend to my customer.
