There’s a lot being written and talked about serverless these days. Whether from the infrastructural or from the software architectural point of view, at minimum it’s worth thinking about this way of deploying and writing software. Calling out to a serverless function from a process or case is one thing, but it gets really interesting when thinking about how a process, case or rule engine can be used to construct a serverless function. Of course, such a thing is not easy.
Flowable core developers Joram Barrez and Filip Hrisafov looked into what it would take to make the Flowable engines ready for this serverless world and recorded a webinar to share the results. In this video, they look at the challenge of getting the cold boot up time as low as possible, while building a real process function that starts and finishes a process when the function is invoked.
Using Spring Cloud and the Spring Cloud AWS function adapter, they demonstrate how to build, package and run a Flowable process function on AWS. After that, they dive into Micronaut and GraalVM to build a native image that boots up a full HTTP REST process endpoint in only 14 milliseconds!
Suffice to say the webinar is worth a watch!

As AI gains prominence as a pivotal technology and enterprises increasingly seek to leverage its capabilities, we are actively exploring diverse avenues for integrating AI into process automation.
The key to managing complexity is to combine different and multiple tools leads to better, faster, and more maintainable solutions. For example, combining BPMN with CMMN.
