Cloud, UC, BYOD Making Network Monitoring Difficult: SurveyBy Jeffrey Burt | Print
Re-Imagining Linux Platforms to Meet the Needs of Cloud Service Providers
Network Instruments’ survey shows growing adoption of trends, but concerns about visibility into the network remain.
In last year's survey, 60 percent said their organizations had adopted cloud computing. That number jumped to 70 percent this year, with 39 percent having deployed private clouds and another 14 percent leveraging external private cloud services, such as Amazon Virtual Private Cloud, Savvis Symphony Dedicated and Citrix Systems' Cloud.com.
Most organizations expect that about half of their applications will be in the cloud within the next 12 months, with the top cloud services being email at 59 percent, Web hosting at 48 percent, storage (45 percent), and testing and development (41 percent).
Twenty-three percent of respondents said they had moved VOIP into the cloud, though only 16 percent had migrated complex services, such as enterprise resource management, in that direction.
Data security remains the top concern about the cloud, with 80 percent calling it the number-one worry. Other concerns include compliance challenges, the lack of ability to monitor the user's experience and to assess the impact cloud is having on network bandwidth. However, 43 percent said the availability of applications in the cloud had improved, and 37 percent said the end-user experience in moving to the cloud also improved.
The adoption of 10 Gigabit Ethernet in the data center is rising rapidly, with 77 percent of respondents saying they will use the technology within the next 12 months, a growth of 52 percent over the last four years. Twenty percent said they will migrate to 40GbE within the next year.
Businesses are anxious to get to 40GbE to help ease bandwidth issues caused by such trends as UC, BYOD and cloud, Network Instruments' Reinboldt said.
"There's just too much data," he said. "There's so much pushing through the pipe … they can't wait anymore."
With applications and networks growing in complexity, resolving problems increasingly becomes an issue. The biggest concern in this area was the inability to identify the source of the problem, according to 70 percent of respondents. Another third said they were still having trouble with bandwidth, according to the survey.
