Cisco cloud survey reveals nonstop growth and expansion

This week, a Cisco cloud survey digs into the explosive growth of cloud data, Xirrus deploys a new Wave 2 access point and Nexthink updates end-user analytics.

Global cloud traffic is expected to more than triple by 2020, as the overwhelming majority of workloads migrate...

to the cloud, according to the sixth annual Global Cloud Index released earlier this month by Cisco.

The Cisco cloud survey projected cloud traffic will rise from 3.9 zettabytes (ZB) in 2015 to more than 14 ZB in 2020, fueled by companies shifting their workloads to public providers, such as Amazon Web Services, Google and Microsoft Azure.

"In the six years of this study, cloud computing has advanced from an emerging technology to an essential scalable and flexible part of architecture for service providers of all types around the globe," said Doug Webster, Cisco's vice president of service provider marketing, in a statement.

For the first time, the report also plotted the growth of hyperscale data centers, projecting they would increase from 259 to 458. The researchers preparing the Cisco cloud survey said these new data centers will be underpinned with software-defined networking and network functions virtualization technologies, with 44% of traffic within these centers supported by SDN and NFV platforms.

Among other findings, the Cisco cloud survey reported, by 2020, more than 90% of workloads will be processed by cloud data centers. Workload density -- that is, how many workloads a physical server can process -- for cloud centers was 7.3 in 2015 and will grow to 11.9 by 2020. More than 65% of cloud workloads will be in public cloud data centers, up from 49% in 2015 -- an annual increase of 35%.

Additionally, internet of things and analytics workloads will become a larger percentage of business workloads, growing from 20% in 2015 to 22% in 2020.

Xirrus launches new AP for high-density Wi-Fi environments

Xirrus introduced a new access point (AP) tailored for high-density Wi-Fi environments. The company, based in Thousand Oaks, Calif., said its XA4 80211.ac Wave 2 AP features external antennas to boost coverage in large venues or open spaces, such as arenas. The vendor said the XA4 can support up to 1,000 simultaneous connections and can reduce the number of APs needed by as much as 75%, compared with legacy APs.

High-density Wi-Fi is becoming more of a requirement in large arenas and stadiums, as well as in business environments with large warehouses or other structures. The design of the XA4 allows enterprises to focus capacity on high-traffic areas on an as-needed basis, Xirrus said.

Nexthink launches new end-user feedback module

End-user analysis is continuing to gain traction, as enterprises begin to focus on how consumers and business partners are interacting with their applications. Nexthink, a Swiss vendor that just opened its first U.S. office in Boston, said it has a better way to capture end-user perceptions with its software, which features a module enabling companies to gather information from end users directly.

Poul Nielsen, the vendor's director of strategy, said Nexthink 6.7 sprang out of complaints from IT professionals, who found that although the number of tickets regarding poor application performance seemed to be declining, end users were simply complaining to one another and not reporting incidents. Nielsen said he believes in an age of hybridized networks and cloud services, where many companies rely on numerous applications and don't control their back end, Nexthink's focus on end-user experience is a more efficient way to track user satisfaction.

"Complexity is our friend," Nielsen said, contending that Nexthink's software is tailored to companies where one group of employees speaks up about an issue, but others do not. Through the use of capabilities within 6.7, he said, administrators can focus their efforts on fixing those problems, while ensuring poor performance isn't costing their companies valuable revenue.

ServiceNow adds AppDynamics tools

Cloud provider ServiceNow said it is now offering application performance management capabilities from AppDynamics as part of its portfolio of services.

The addition of AppDynamics means ServiceNow enterprise customers will be able to mesh the software company's application behavior features as part of ServiceNow's configuration management database, according to David Abramowski, ServiceNow's senior director of IT operations management. "This will give our customers a more comprehensive picture of service health," he said. The new tools are part of ServiceNow's ServiceWatch Insight offering.
