IoT gateways and risk management

As previously posted in IoT Evolution

As more industry organizations take their first cautious steps towards the Internet of Things (IoT), they are quickly realizing the need for a new class of systems: the IoT gateway. As with any new technology introduced into an industrial environment, the question arises: will new risks arise?

 

The IoT gateway sits between systems at the edge and centralized control and management systems, often linked through the cloud. The gateway collects data from hundreds or thousands of sensors and other advanced systems by broadcasting protocols and device control models. IoT gateways are moving from simply providing this broadcast function to smart systems that provide higher-level control functions at the edge and ultimately reduce the burden on central control systems.

 

System vendors have taken advantage of the growing demand for IoT gateways by offering turnkey solutions that combine software and hardware. In fact, you will find a range of IoT gateway solutions offered by some of the most renowned computer hardware manufacturers. These systems have some attractive features. They are generally robust and designed specifically for workshop use. And they are usually cheap. What's not to like?

 

Unfortunately, these systems also have some limitations. They usually don't have much power; they cannot replace the current Edge Servers. They are not virtualized - and if they are, they can be as expensive as a more complete system. And because they are based on low-cost off-the-shelf equipment (COTS), the expected lifecycle is limited, as are the expectations for reliable support from suppliers.
