The survey highlighted topics including server, client, and storage virtualization and hybrid/private cloud technologies.
recent Symantec survey on virtualization and cloud computing found adoption of
server virtualization is widespread, with more than 75 percent of organizations
discussing private and hybrid cloud deployments. Of the technologies evaluated
in the survey-which examined how organizations plan to move business-critical
initiatives to virtual and hybrid cloud computing environments-server and
storage virtualization are the most mature with 45 and 43 percent of
enterprises implementing, respectively. Private storage-as-a-service is the
least mature, with 36 percent adopting.
2011 Virtualization and Evolution to the Cloud Survey highlighted topics including
server, client and storage virtualization; storage-as-a-service; and
hybrid/private cloud technologies. The results uncovered disparities between
expectations and reality as enterprises deploy these solutions. CEOs and CFOs
are concerned with moving business-critical applications into virtual or cloud
environments due to challenges, including reliability, security, availability
and performance. The survey was based on more than 3,700 respondents from 35
computing represents a major shift within IT-changing from a traditional IT
delivery to a service-provider model. Moving to the cloud is a complex
evolution for many companies, and it's essential that IT and executives are
aligned on initiatives," said John Magee, vice president of virtualization and
cloud solutions for Symantec. "Virtualization is an enabler for private and
hybrid clouds, and our survey shows that planning a seamless move is critical
to achieving all the simplicity, affordability and efficiency that these environments
have to offer."
survey indicated that organizations are leveraging virtualization for
business-critical applications. Of enterprises that are implementing
virtualization, more than half (59 percent) plan to virtualize database
applications in the next 12 months. Fifty-five percent plan to virtualize Web
applications, and 47 percent plan to virtualize email and calendar
applications. Forty-one percent plan to virtualize ERP applications.
survey also found that organizations are more slowly leveraging hybrid/private
cloud technologies for business-critical applications. An average of just 33
percent of business-critical applications such as ERP, accounting and CRM are
in hybrid/private cloud environments. Respondents stated concerns over account,
service or traffic hijacking; authentication vulnerabilities; access
vulnerabilities; disaster recovery; and encryption.
virtualization and private cloud technologies become more widely adopted, the
cost and performance of storage are becoming increasingly top of mind, the
survey found. More than half of the respondents (56 percent) said storage costs
somewhat or significantly increased with server virtualization. Of those in the
process of virtualizing storage, the top three reasons for deployment include
reducing operating expenses (55 percent), improving storage performance (54
percent) and improving disaster recovery readiness (53 percent).
percent of enterprises that have implemented server virtualization indicated
that security was a somewhat/extremely large factor in keeping various
constituents from being more confident about placing business-critical
applications on virtualized servers. Sixty-three percent listed security as a
significant/extreme challenge to implementing server virtualization.
to the survey findings, 46 percent of CFOs who are implementing hybrid/private
clouds are less than "somewhat open" to moving business-critical applications
into those environments. Forty-four percent of CEOs are cautious about moving
these applications. Main concerns cited about virtualization and hybrid cloud
deployments are reliability (78 percent), security (76 percent) and performance
