Vas is a Technical lead and the Virtualization Strategic Initiative Manager in the Virtualization Runtime & Tools Department. Vas presented us with an interesting talk about Virtualization technology and how it is driving profound changes in the way large data centers are designed and managed. Moving to a virtualized infrastructure solves many problems such as hardware utilization and power consumption. But it also creates many new problems such as virtual machine image sprawl and a new management layer in the IT stack. The talk included an interesting overview of the emerging trends in the industry by the adoption of virtualization, followed by an IBM Research perspective of what new technical challenges this creates.
