There are no technology barriers for creating an application for the IndustryApps platform. You need to comply with certain standards to make your application work with the platform.
IndustryApps uses an Application Service Registry (Service Discovery) to keep track of all app instances. The apps should register to the Service Registry to get the apps discoverable in the customer platform.
We use the Netflix Eureka to implement the Service Registry. Our Customer Platform will be the Eureka Server and the apps will be working as Eureka clients.
Eureka client integration will be simple using the dependency libraries available for different programming languages and frameworks.
