By 2020, the internet of things (IoT), analytics, and database applications will make up 22% of all business workloads in cloud data centers, an increase from the 20% businesses saw in 2015. These big data applications will most likely be "cloud-native," or designed to run in the cloud, and the growing use of them will be at the center of enterprises' movement into the cloud. However, even as the enterprise moves into the cloud, its claim on the world's total cloud computing resource will shrink compared the role of the consumer, according to the Cisco Global Cloud Index released Nov. 10. In 2015, enterprises accounted for 79% of the workloads in either public or private clouds. By 2020, that share will drop to 72%, offset by the growing consumer use of the cloud.
Cloud computing is expected to quadruple within the next few years. It's predicted that only 8 percent of all workloads will continue to be processed by traditional data centers, while 92 percent will be processed by cloud data centers. Recent estimates by Cisco predict that there will be a number of changes by the year 2020. Those changes include an increase to 14.1 zettabytes in cloud traffic. Big data and the Internet of Things are big contributors to this growth, with the amount of data generated by IoT predicted to reach 600 ZB per year.
Businesses are migrating to cloud architectures at a rapid clip and by 2020, cloud traffic will take up 92 percent of total data center traffic globally, according to Cisco's Global Cloud Index report. The networking giant predicts that cloud traffic will rise 3.7-fold up from 3.9 zettabytes (ZB) per year in 2015 to 14.1ZB per year by 2020. "The IT industry has taken cloud computing from an emerging technology to an essential scalable and flexible networking solution. With large global cloud deployments, operators are optimizing their data center strategies to meet the growing needs of businesses and consumers," said Doug Webster, VP of service provider marketing for Cisco, in a press release. "We anticipate all types of data center operators continuing to invest in cloud-based innovations that streamline infrastructures and help them more profitably deliver web-based services to a wide range of end users."
This ebook, based on the latest ZDNet/TechRepublic special feature, takes a close look at the current enterprise trends surrounding cloud migrations. The use of cloud computing services and applications continues to increase at a rapid rate, leading to the rise of vast'hyperscale' cloud data centers. Both consumer and business applications are contributing to the growing dominance of cloud services. For consumers, streaming video, social networking, and search are among the most popular cloud applications; for business users, enterprise resource planning (ERP), collaboration, and analytics are the top growth areas, according to research from Cisco. And, driven by the rapid increase in use of cloud apps, data center traffic is growing fast, expected to reach 19.5 zettabytes (ZB) per year by 2021, up from a mere 6.0ZB per year in 2016, according to Cisco.
