According to Sixth Annual State of the Network survey from Network Instruments, organizations are continuing their steady deployment of 10 GbE as bandwidth needs grow.
The study found that 59 percent of survey respondents have already 10 GbE deployed. An additional 18 percent plan to deploy 10 GbE in the next 12 months. When it comes to 40 GbE, on the other hand, only 6 percent have deployed it to date, with 14 percent planning deployment in the next 12 months.
"We found the 40 GbE numbers to be impressive," Brad Reinboldt, senior product manager at Network Instruments, told Enterprise Networking Planet. "Early on we thought that people would jump from 10 GbE directly to 100 GbE."
38 percent of organizations have deployed private clouds, outpacing the public cloud's 30 percent. More cloud growth appears imminent: 18 percent of the study's respondents indicate plans to deploy private cloud in the next 12 months. 29 percent indicated that they planned to deploy Public Cloud in the next 12 months.
When combined, public and private cloud adoption totals represent a nearly 10 percentage point gain over the 2012 State of the Network study.
In terms of what applications are being deployed in the cloud, 59 percent indicated email, 48 percent said web hosting, and 45 percent said storage. 41 percent of the study's respondents cited test and dev application use cases.
From an impact perspective, 43 percent said that the cloud has improved service availability, while 52 percent indicated that it has remained the same. The remaining two percent reported that the cloud has actually had a negative impact on service availability.
The cloud has also not necessarily been a net gain for troubleshooting either. Only 18 percent of respondents said that the cloud has improved troubleshooting. In contrast, 59 percent said troubleshooting ability remained the same. 23 percent said it declined.
Not surprisingly, security was the top concern, cited by 80 percent of respondents. Compliance-related problems came in second on the list of concerns at 39 percent.
"There is a nagging concern that because it's not the same data center that the enterprise can reach out and touch literally and figuratively, that somehow there is a hit from the security perspective," Reinboldt said.
The study also found that server virtualization is well deployed at this point, with 85 percent of survey respondents indicating that it's already in place.
Surprisingly, the State of the Network study does not mention Software Defined Networking (SDN) at all. Reinboldt explained that the reason why his company's report doesn't include SDN is quite simple - they didn't ask.
"The fact that it wasn't asked speaks to how quickly technologies change," Reinboldt said. "Believe us, it will be on next year's survey."
Earlier this year, research group IDC forecast that the market for SDN would generate $3.7 billion by 2016.
