2014 Top Tech Trends
• 1) Internet of Things• The IoT promises to be the
most disruptive technological revolution since the advent of the World Wide Web. Projections indicate that up to 100 billion uniquely identifiable objects will be connected to the Internet by 2020, with enormous technical, socioeconomic, political, and even spiritual consequences.

What is the Internet of Things?
• Cisco “Internet of Everything”– …the latest wave of the Internet -- connecting physical
objects…to provide better safety, comfort, and efficiency• IBM “Internet of Things”
– …a completely new world-wide web, one comprised of the messages that digitally empowered devices would send to one another. It is the same Internet, but not the same Web.
• GE “Industrial Internet”– …convergence of machine and intelligent data…to create
brilliant machines• RTI “Your Systems. Working as One.”
– RTI exists to enable and realize the potential of smart machines to serve mankind… The IoT is as profound as the cell network, GPS, or the Internet itself. The Internet of Things and the Intelligent Systems it enables will fundamentally change our world.

Message Centric Approach
• Traditional middleware exchanges messages• Infrastructure is unaware of the content• Developers write applications that send messages
between participants
Popular standards: JMS API; AMQP wire spec
Data Centric Approach
• Data-centric middleware maintains state• Infrastructure manages the content• Developers write applications that read and update a virtual
