Val Huber presents on how low-code development platforms can provide both business agility through empowering knowledge workers to build their own systems, as well as enterprise-scale capabilities. The presentation discusses how early low-code platforms were limited but modern approaches can instantly generate databases and applications from business concepts, include reactive business logic, and provide API servers for integration. This allows both empowering end users while also delivering scalability, performance, and architectural features required by large organizations.

Abstract
Empowering knowledge workers to create their own systems is a great approach to business
agility. But the apps are often “toys” (i.e., they scale poorly, no APIs, no business logic, not
integration ready).
But the App Economy demands more than agility. Doing business across multiple business
channels requires Enterprise-class systems that scale, protect their data and are accessible
across multiple business channels.
This talk will imagine an approach that preserves the agility that users want, with enterprise-
class capabilities the organization needs.
