In the economics of computing the most expensive resource is still the network. In scenarios where large data-sets are being processed it is almost always cheaper to move computation to the data than the other way round. My friend and former colleague Dave McCrory nicely captured this reality in his concept of Data Gravity.Today’s cloud based computing architectures assume that all data will flow to the center to be processed. Unfortunately, this centralized data-processing model is not likely to be economically viable as we look forward to a tsunami of data being generated by trillions of connected devices and sensors.
In the brave new world of the ‘Internet of Things’ – IoT – moving every bit of generated data from edge devices to the center for processing will likely make little economic sense. A new distributed data processing architecture is going to be required.
Content Distribution Networks (CDNs) are a common way of efficiently moving data from the center to the edge of the network but a new generation of Content Aggregation Networks (CANs) may be required to make the processing of IoT data economically viable – is there a ‘CAN’ in your future?
