Absolutely, 100%.

I work on PeopleSoft Enterprise Resource Planning applications - the "boring" back-office HR, Pay, Financials, Planning etc stuff.

The core architecture is late 80s - mid 90s. Couple of big architectural changes when internet/browsers and then mobile really hit. But fundamentally it's a very legacy / old school application. Lots of COBOL, if that helps calibrate :->

We use queues pervasively. It's PeopleSoft's preferred integration method for other external applications, but over the years a large number of internal plumbing is now via queues as well. PeopleSoft Integration Broker is kind of like an internal proprietary ESB. So understanding queues and messaging is key to my PeopleSoft Administrator teams wherever I go (basically sysadmins in service of PeopleSoft application:).

Recently, I also started using queues for integrating with legacy health care applications. Most of them run on-promise and they don't have incoming internet connection for security reasons. The strategy is to send a message to a queue. The consumer application uses short polling to process the messages and then it can call a webhook to share the status of the job. Do you also follow a similar approach?

If I understand it correctly, no; PeopleSoft is Legacy in some ways but it is actively developed and improved/maintained. The Peoplesoft Integration Broker is "modern-ish" from that perspective, and a proper middleware messaging system:

It'll do XML messages in somewhat proprietary format with other PeopleSoft applications, and "near-real-time" queues via web services with other applications in a fairly standardized way (WSDL etc). I think of PeopleSoft Integration Broker as a "mini, proprietary ESB", as inaccurate as it may be in details :).
