GraalVM is an open source set of projects driven by Oracle Labs, the Institute for Software Kepler University Linz Austria, and a community of contributors. GraalVM seeks to usher in the age of true language interoperability without the pains of many past approaches. If polyglot development and deployment appeals to you, or is a requirement, then this technology will enable a new set of tools in your toolbox. Iran Hutchinson will briefly review the project, why it's important, and what it enables. He'll then conclude with viewing some example experiments he's working on using the GraalVM approach.
