Users need to warily embrace virtualisation, according to speakers at Interop assessing how to proceed with technology investments in the face of possible IT budget cuts.
Interop shared space with Mobile Business Expo in an effort to bolster both events in an economy where trade show attendance is flagging, and together they hoped to draw a total of 13,000 people over the course of the four-day event, show officials said.
Those who attended Interop heard that cloud computing will help companies accomplish more, but new security threats must be overcome in order to fully benefit from this new technology, speakers said.
Virtualisation is a "chameleon concept" with one common denominator: breaking the bond with physical reality "so you can do more," Marie Hattar, vice president of network systems and security solutions at Cisco, said during her keynote address. "It's one asset to many, or many assets to one," she said.
But perhaps the most critical issue is the new and numerous security holes opened up by virtualisation and cloud computing. "A hypervisor needs hypersecurity," Hattar said, as Cisco found out when it virtualised its own servers. "We have to rethink our security approach because when we virtualised, it increased complexity. In cyberspace, there are a lot more points of entry."
She stressed that companies embarking on virtualisation and cloud computing need to plan copiously for operations, management, control and security of the new infrastructure.
Her points were echoed by Novell President and CEO Ron Hovsepian, who said companies need to overcome challenges such as reduced spending, complex management and risk mitigation in order to have their heterogeneous IT assets work as a unified system.
Key to bringing IT assets together are injecting agility into the data centre through virtualisation; enhancing end-user productivity through collaboration and pinpoint management of enterprise desktops; and then implementing and enforcing companywide IT identity and security policies and procedures through access and compliance management strategies.
