Potential good news: You likely won't have a flood of IoT devices coming from all quarters as we saw in the early days of mobile BYOD. But what IoT devices you have will be very hard to manage.
Remember when there were iPhones, Android smartphones, BlackBerrys, WebOS phones, Windows Phones, and legacy Windows Mobile devices? IT shops freaked out at all the variations they'd have to support.
Imagine an IoT world where thermostats, door locks, light switches, elevator stop regulators, smart glasses, Bluetooth internal-location sensors, comm badges, security cameras, heat sensors, conference gear, alarms, and the gazillion other devices and sensors that might exist in the products you use and environments you manage -- as well as the possible IoT devices and sensors in health care, transportation, oil exploration, logistics, retail, and public safety. In comparison, the half-dozen mobile devices that so freaked out IT look as frightening as a sleeping cat.
The best example here is Wi-Fi. Until the Wi-Fi Alliance, a vendor group, came up with the Wi-Fi wireless compatibility standard, businesses refused to adopt wireless LANs in any volume because pre-Wi-Fi devices could only talk to other devices from the same company, though they all used the same 802.11 transport protocol.
One example in IoT is the Data Distribution Service, a set of APIs and data transfer protocol from the Object Management Group. This lets various manufacturers' devices talk to various manufacturers' analytics back ends.
We'll see both patterns occur in IoT. But it will take years for the shift to either approach in each domain. In the meantime IT will be faced with a grim reality: Most IoT products will have their own security models and management tools, creating an unwieldy mess for IT. That'll slow IoT adoption out of necessity.
In the industry standardization game, someone has to blink first, but the stare-down will go on for years until someone finally has to back off. In the meantime, pick and choose your IoT initiatives carefully -- you'll be able to handle only so many of them.
