The number of servers managing the world's data will grow tenfold over the next 10 years, according to the IDC Digital Universe study. The study also predicts that overall data will grow by 50 times by 2020, mostly due to the proliferation of embedded systems such as sensors in clothing and medical devices. In addition, the study found that unstructured information will make up about 90 percent of all data created in the next 10 years, while metadata is growing twice as fast as the digital universe.
Despite the inevitable increase in data, new hardware and software technologies have driven the cost of creating, capturing, and managing information down to less than 20 percent of what it was in 2005. "As an industry, we've done a tremendous job at lowering the cost of storing data," says IDC's David Reinsel.
Since 2005, yearly investments by enterprises in hardware, software, and cloud services has increased 50 percent to about $4 trillion, according to the IDC report. Today, cloud computing accounts for just two percent of information technology spending, but by 2015 nearly 20 percent of all information will be associated with the cloud in some way, according to the IDC study.
