     So what is the Internet of Things? Simply put, it’s machine-to-machine communication, but it’s much more than just connected devices. What is the Internet of Things, exactly? It is an ambiguous term, but it is fast becoming a tangible technology that can be applied $\in$ data centers to collect information on just about anything that Information Technology (IT) wants to control. The Internet of Things (IoT) is essentially a system of machines or objects outfitted with data-collecting technologies so that those objects can communicate with one another. The machine-to-machine (M2M) data that is generated has a wide range of uses, but is commonly seen as a way to determine the health and status of things – inanimate or living.
     IT administrators can use the IoT for anything $\in$ their physical environment that they want information about. In fact, they already do. In one case, IoT is being used to stymie deforestation $\in$ the Amazon rainforest. A Brazilian location-services company called Cargo Tracck places M2M sensors from security company Gemalto $\in$ trees $\in$ protected areas. When a tree is cut or moved, law enforcement receives a message with its GPS location, allowing authorities to track down the illegally removed tree.
     One analyst explained the IoT using the iPhone as an analogy. Disconnected third-party applications that are hosted $\in$ the cloud can be connected, and users can access all sorts of data from the device, according to Sam Lucero, senior principal analyst, M2M and Internet of Things, at IHS Electronics & Media $\in T$empe, Ariz.

How the Internet of Things works

     While some consider IoT to be M2M communication over a closed network, that model is really just an intranet of things, Lucero said. With an Intranet of Things, apps are mobilized for a specific purpose and don’t interact outside of that network. The true IoT is where different applications are mobilized for specific reasons and the data collected from the machines and objects being monitored are made available to third-party applications. The expectation is that true IoT will provide more value than what can be derived from secluded islands of information, Lucero said.

     For the IoT to work $\in$ data centers, platforms from competing vendors need to be able to communicate with one another. This requires standard APIs that all vendors and equipment can plug into, for both the systems interfaces as well as various devices, said Mike Sapien, a principal analyst with Ovum.
