Setting the stage: The attack of the exponentials

The question of why this style of startup is arising today, versus a decade ago, owes to a confluence of forces that I call the Attack of the Exponentials. In short, over the past five decades, the cost of storage, CPU, and bandwidth has been exponentially dropping, while network access has exponentially increased. In 1980, a terabyte of disk storage cost $14 million dollars. Today, it’s at $30 and dropping. Classes of data that were previously economically unviable to store and mine, such as machine-generated log files, now represent prospects for profit.

At the same time, these technological forces are not symmetric: CPU and storage costs have fallen faster than that of network and disk IO. Thus data is heavy; it gravitates toward centers of storage and compute power in proportion to its mass. Migration to the cloud is the manifest destiny for big data, and the cloud is the launching pad for data startups.
