Cloud computing is inexpensive, stressed Michael Crandell, CEO of RightScale, which offers cloud management for deploying mission-critical applications. He listed other drivers to the cloud as scalability and access to resources.
Barriers to cloud adoption include lock-in, security, service-level agreements, regulatory compliance, and loss of control of underlying infrastructure, Crandell said.
"On the obstacle side, lock-in, interestingly enough, is the No. 1 obstacle that we hear mentioned among customers and prospects that we speak with," said Crandell, adding that RightScale addresses obstacles to the cloud.
He listed customer examples, including a biopharmaceutical company using the cloud for wikis for its global workforce, grids for protein analysis, and compute-intensive statistical analysis.
Crandell said commoditization in the cloud space is happening and is good in that it creates standards and the ability to replicate. It also can lower prices. But even at the cloud infrastructure level, differentiation is occurring, said Crandell. He cited as an example Amazon's Availability Zones capability to protect applications from failure of a single location.
An attendee cited software licensing as an issue with cloud computing and virtualization.
"The challenge with enterprise software is a lot of enterprise software license terms are bound by hardware configurations," said Mehmet Orun, a senior manager at a biotechnology firm that has used cloud computing.
He asked if vendor legal groups were ready to accommodate a flexible model to allowing for differing demands for software at different times, such as meeting peak demands at certain times of the year.
