And finally, IoT is emerging in so-called smart cities, where all kinds of devices and assets such as traffic lights, parking meters and garbage truck fleets are gradually being connected to the Internet. Municipal government IT executives will need to be aware of how these assets tie in to the network.
IT and OT convergence
What will likely happen is a convergence of operational technology and IT. "As these machines go onto the corporate network the CIO or the COO need to start talking together about what the future is going to look like when traditional IT stuff and OT stuff are overlapping on the network," LeHong says.
"Who is responsible for providing security, for example," LeHong says. "There are skill sets that exist in IT that are very developed, but that are new or not a prime focus for the operations guy. There can be some synergies."
IT executives will need to prepare themselves for situations such as when an IP-based vending machine is creating software replenishment orders for out-of-stock items using an enterprise resource planning application, LeHong says.
"When it creates the replenishment order does the vending machine need a user license" for the ERP application, LeHong says. "CIOs need to get an understanding of this. Even if they are not going to own the vending machines, they need to worry about things like that. That's what we mean by convergence. OT and IT can't sit in separate worlds anymore. They need to discuss things like governance, security, software licensing and maintenance."
In terms of networking technology and strategies at enterprises, IoT will have a significant impact. According to a report on IoT trends published by Gartner in 2012, things will be connected, but not necessarily in the ways most familiar to companies today.
"Wi-Fi, 3G/4G cellular and Bluetooth are the wireless connectivity technologies we are most familiar with; however, they will not be the only way things connect to the Internet," the report states.
These network technologies and protocols consume lots of power and are designed for higher-bandwidth applications, the firm says, but many things (for example, a temperature/humidity sensor in a remote agricultural setting) will require low bandwidth, long range and very low power consumption.
In addition, things will need to be addressable. Every computer, smartphone and tablet is addressable on the Internet, directly or indirectly via IP, the Gartner report says, and "it follows that things will also need to be addressable so they can communicate with other things, applications and people on the Internet."
While not every "thing" will have an IP address, it will need to be addressable.
Then there are the data management issues. Getting the most value out of IoT requires an ability to manage data and gain insight from analyzing that data, Gartner says.
If everything has the potential to provide some type of data stream, companies will need technologies to manage, store and analyze the data. While some organizations might be able to leverage existing information management tools, many will need to bring in new technologies designed to handle the real-time and large-scale nature of the IoT.
Recent IT trends such as the move to the cloud and implementations of big data and analytics will likely come into play with the IoT, experts say.
"Are you going to procure cloud services for hooking up these things to the corporate network?" LeHong says. "And it's not just questions about the cloud, but about end-point management and architecture. Let's say you have a jet engine or a pump in an oil field that can produce a terabyte of information per day. That's a lot of data."
From an architectural standpoint, IT and operations will need to decide whether to store that data on site, in the cloud or in a corporate data store.
Looking ahead to the next few years, growth of the IoT will probably be greatest in areas such as inventory tracking and supply chain management, Castro says. But given the way technology is developing, it's likely that the IoT will be pervasive in many aspects of business.
