The first wave of integrating storage, compute and networking hardware helped businesses move from client/server to internet-based peer-to-peer networks.

Messaging-oriented middleware is at the heart of enabling such a frictionless integration between a business' core assets: its applications and data residing on the network. However, integrating multi-vendor applications with diverse infrastructure and legacy applications is a daunting task.
