How and why I turned my old Java projects into a first-class serverless component

mit Mario Fusco
Vortragssprache: Englisch / Language: English

These days rule engines are often overlooked, possibly because people think that they are only useful inside heavyweight enterprise software products. However, this is not necessarily true. Simply put, a rule engine is just a piece of software that allows you to separate domain and business-specific constraint from the main application flow. I am the project lead of Drools, the rule engine of Red Hat, and my target was to modernize my project and make it ready to be used in serverless environments. In this talk I will explore and make sense of technologies like GraalVM and Quarkus. In particular I will show, with very practical use cases taken from my experience with this migration, what is necessary to change in a code base making extensive use of reflection, dynamic class loading and other Java sorceries in order to make it compatible with those technologies and demonstrate how this is allowing us to make Drools part of the cloud and serverless revolution.

 

Mario Fusco

Mario Fusco is a principal software engineer at Red Hat working as Drools project lead. He has a huge experience as Java developer having been involved in (and often leading) many enterprise level projects in several industries ranging from media companies to the financial sector.
Among his interests there are also functional programming and Domain Specific Languages. By leveraging these 2 passions he created the open source library lambdaj with the purposes of providing an internal Java DSL for manipulating collections and allowing a bit of functional programming in Java. He is also a Java Champion, the JUG Milano coordinator a frequent speaker and the co-author of "Modern Java in Action" published by Manning.
