A new press release reports, “Today, Cisco released the seventh annual Cisco® Global Cloud Index (2016-2021). The updated report focuses on data center virtualization and cloud computing, which have become fundamental elements in transforming how many business and consumer network services are delivered. According to the study, both consumer and business applications are contributing to the growing dominance of cloud services over the Internet. For consumers, streaming video, social networking, and Internet search are among the most popular cloud applications. For business users, enterprise resource planning (ERP), collaboration, analytics, and other digital enterprise applications represent leading growth areas.”

The release goes on, “Driven by surging cloud applications, data center traffic is growing fast. The study forecasts global cloud data center traffic to reach 19.5 zettabytes (ZB) per year by 2021, up from 6.0 ZB per year in 2016 (3.3-fold growth or a 27 percent compound annual growth rate [CAGR] from 2016 to 2021). Globally, cloud data center traffic will represent 95 percent of total data center traffic by 2021, compared to 88 percent in 2016. In the past, security concerns have been a major barrier to cloud adoption. Improvements in data center governance and data control have helped to minimize enterprise risk and better protect consumer information. Security innovations coupled with tangible cloud computing benefits, including scalability and economies of scale, play key roles in fueling the cloud growth projected in the study.”
