Why Virtualize Servers?

• IT flexibility/agility• Predictable scaling to dynamically respond to business needs

• Key part of disaster recovery strategy

• Server or data center consolidation• Higher utilization leads to greater consolidation

• Promotes greater centralization and security

• "Green Computing"• Consume less power, cooling, and real estate

• Support DevTest environments• Works for both IT shops and development houses

• Desktop virtualization

• Hypervisor runs on bare metal• Extremely thin; only 50K lines of code

• Processor and memory access through hypervisor

• Network and storage • Accessed through management domain

• Uses standard Linux device drivers

Paravirtualized guests makes high-speed calls directly to the

hypervisor

Other guests benefit from hardware-accelerated call

translation

Paravirtualization• Kernel and I/O paths know

they are being virtualized

• Cooperation provides best performance

Hardware-assisted• Hardware-assist allows

high performance without emulation

Fast, Effortless Provisioning

• Traditional "virtual" provisioning• Create virtual machine

• Duplicate virtual disk/virtual machine to create new virtual machines

• Improves provisioning with templates• Creating a virtual machine from a template is single-step

• New virtual machines provisioned in seconds

Simplify DevTest

• Two aspects to DevTest• IT infrastructure

• Application development

• Improve IT DevTest flexibility• Smaller organizations do not have full DevTest environments

• Replicate production environment with fraction of the resources

• Qualify patches and application changes

• Push images rapidly from DevTest (virtual) to production (physical)

• Enhance application development on XenApp• Create virtual servers for application development silos

• Especially complementary for off-shore development

Consider desktop virtualization when:

• Doing desktop rollouts

• Desktop security for compliance and IP protection

• Business continuity

• Desktop refresh

Key Takeaways

• Highly complementary: server virtualization and desktop virtualization• Add resiliency and flexibility IT operations

• Easily support rapid provisioning, high availability, DR, and DevTest

• Obviously, your (virtualization) mileage may vary

• Virtualization is not just for the datacenter anymore• 40% lower cost of desktop maintenance & support

• Reduced risk of data loss

• Deliver desktops quickly a reliably to any location

• Don´t forget app virtualization
