1. Introduction to The Paremus Services Fabric 19 January 2012 OSGi™ Users’ Forum DC Metro … a distributed application server for running OSGi technology-based applications across anything from a few computing resources to a large-scale Cloud. The Paremus Service Fabric extends OSGi technology’s dynamic module capabilities across multiple network-connected Java Virtual Machines (JVMs) to create an incredibly robust and efficient distributed platform for enterprise applications.
