The ESB service bus includes the means of rapid development, consisting of a large spectrum of pre-programmed actions, for example:
- to get / send a message via JSON or as XML to FTP;
- to get / send product information from one system, and in the absence of the required attribute to "turn to" another system to get it and then put it in a queue to add it to yet another system.
As a rule, if a change of logic is required, it is made with several lines of code, and sometimes with a single line.
