3. DEFINITION OF
VIRTUALIZATION
● Virtualization is the technology that
allows you to create and manage
virtual instances of computer
hardware, software, storage, or
networks within a single physical
infrastructure.

4. TYPES OF VIRTUALIZATION
BARE-METAL
VIRTUALIZATION
Also known as Type 1 or hypervisor-based
virtualization, runs directly on the hardware.
Key Features:
• No underlying operating system.
• Hypervisor controls hardware resources.
• High performance and resource efficiency.

5. BARE-METAL
VIRTUALIZATION
To built a Type I Hypervisor:
• Data Cabinet
• Install Motherboard, CPU, RAM and
Storage Devices.
Installing a Type I Hypervisor:
Example.
• Vmware ESXI/PROXMOX VE.

6. BARE-METAL
VIRTUALIZATION
Create 3 Virtual Machine
• Allocating the server’s hardware
resources.
• Install Operating System.
• Installing Applications.

7. TYPES OF VIRTUALIZATION
HOSTED OPERATING
SYSTEM VIRTUALIZATION
Hosted virtualization, also known as Type 2 or
OS-level virtualization, relies on an underlying
operating system.
Key Features:
• Requires a host operating system.
• Multiple virtual environments run on top of
the host.
• Simplicity and ease of setup.

8. HOSTED VIRTUALIZATION
A Type II Hypervisor runs on top of
an Existing Operating System.
Typically used on personal
computers.
• To test new software
• Try out different operating
system
Type II hypervisor
• Oracle VM VirtualBox
• Vmware Workstation
• Microsoft Virtual PC

10. COMPARISON - PERFORMANCE
BARE-METAL HOSTED
• Higher performance due to direct
hardware access.
• Ideal for resource-intensive
workloads.
• Slightly reduced performance due to
the additional OS layer.
• Suitable for lightweight workloads and
development environments.

11. COMPARISON – RESOURCE ISOLATION
BARE-METAL HOSTED
■ Strong isolation between virtual
machines.
■ Each VM has dedicated
resources.
■ Limited isolation; VMs share
the host OS resources.
■ Less secure for multi-tenant or
critical environments.

12. FLEXIBILITY
COST SAVING
ENHANCED
MANAGEMENT
SCALABILITY
Enables rapid provisioning
and deployment.
Simplifies resource management
and maintenance.
Reduces hardware expenses
and energy consumption.
Efficiently utilizes server
capacity and storage.
Easily scales up or down
to meet hanging demands.
Facilitates backup,
replication, and recovery.

BENEFITS OF VIRTUALIZATION

13. USE CASES OF VIRTUALIZATION
Data Centers
Efficiently utilize server resources and reduce
physical footprint.
Cloud Computing Foundation for cloud infrastructure and services.
Development and
Testing
Isolated environments for software testing.
Desktop Delivery
Centralized desktop management for remote
access.
High Availability Ensure application uptime through redundancy.

14. CHALLENGES IN VIRTUALIZATION
1. Security: Protecting virtualized
environments from threats.
2. Performance: Ensuring adequate
performance for virtual workloads.
3. Management Complexity: Properly
configuring and monitoring virtual
resources.
