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.

Queuing

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 global data space
