CompTIA Server+ Certification 3.2 Virtualization Technologies

Objectives Describe different technologies that can be used to implement virtual platforms: – Host-based – Bare metal – Server infrastructure – Virtual Desktop Infrastructure – Storage Understand the use of virtualized applications and cloud computing Describe the advantages and disadvantages of virtual platforms 3.2 Virtualization TechnologiesSlide 2

Virtualization Defined Hardware platform Hypervisor – Host-based (rely upon an underlying OS) – Bare-metal Guest operating systems 3.2 Virtualization TechnologiesSlide 3

Hypervisor Assign resources to each guest OS Configure networking and interconnectivity Security - ensure that guest OS are "contained" 3.2 Virtualization TechnologiesSlide 4

Management Server Receive any alerts or alarms generated by the VMs or hypervisors Allow the configuration and starting or stopping of VMs remotely Provide tools for managing the virtual network Deploy new VM images or move VMs between physical servers Deploy security patches and updates to hypervisors and VMs Set up disaster recovery plans and failover / redundant services and resources Monitor and optimize performance 3.2 Virtualization TechnologiesSlide 5
