3. Server Virtualization

4. Server Virtualization
In most applications that sit on a single dedicated server,
most of the CPU, RAM and other resources are idle most
of the time and go unused.
Server virtualization is where multiple virtual servers are
run on a particular physical server. A virtual server can
have its own operating system, applications, available
resources, security policies, etc.

6. Classification of Virtualization
Technologies
👉 Bare-metal virtualization
👉 Hosted virtualization

7. Bare-metalvirtualization
Bare-metal virtualization means the hypervisor has direct
access to hardware resources, which results in better
performance, scalability and stability.
Well suited for enterprise data centers, because it usually
comes with advanced features for resource management,
high availability and security. Admins can centrally
manage this kind of virtualization hypervisor, which is
critical when you have many hosts in your virtual
infrastructure.

8. Bare-metal virtualization
The most popular bare-metal virtualization
hypervisors are:
✘VMware ESXi
✘Microsoft Hyper-V
✘AIX LPAR
✘HPUX NPAR & VPAR

WhiteBoard

11. Hosted virtualization
Hosted virtualization requires you to first install an OS.
These hypervisors are basically like applications that
install on a guest OS.
A hosted virtualization hypervisor does not have direct
access to hardware and must go through the OS, which
increases resource overhead and can degrade virtual
machine (VM) performance.

12. Hosted virtualization
The most popular hosted virtualization hypervisors are:
✘Oracle VM VirtualBox
✘Microsoft Virtual PC
✘HP VM
✘AIX VIO
✘SuSe Xen

15. Benefits Of Server Virtualization
👉 Reduce the Footprint of Data Center
👉 Set Up Test Server, QA, R&D, and more
👉 Fast Server and Resource Provisioning
👉 Reduce Hardware and Vendor Lock-In Requirements
👉 Increase Uptime and Availability

16. Benefits Of Server Virtualization
👉 Improve Disaster Recovery
👉 Isolate Applications
👉 Extend The Life Cycle of Older Applications
👉 Help Move Things to The Cloud
👉 Go Green & Save Energy
