The document summarizes a seminar presentation on virtualization and containerization. It begins with an introduction comparing virtualization and containerization. It then covers key topics in virtualization including the different types (hardware, desktop, application, server, storage, network), reasons for virtualization, and components like the hypervisor. The presentation also discusses containerization and its benefits compared to virtualization.

4. 1. Introduction to virtualization and
containerization?
• Virtualization and containerization
are the two most frequently used
mechanisms to host applications in
a computer system.
• Virtualization uses the notion of a
virtual machine as the fundamental
unit.
• Containerization, on the other
hand, uses the concept of a
container.
• Both of these technologies play a
crucial role and have their merits
and demerits.

5. 2. What Is Virtualization?
• Virtualization, In computing refers to
the act of creating a virtual version
rather than the actual version of
something, including but not limited
to a virtual computer i.e. hardware
platform, OS, storage devices,
computer network resources.
• Virtualization relies on software to
simulate hardware functionality and
create a virtual computer system.

6. Types of virtualization
1) Hardware virtualization
2) Desktop virtualization
3) Application virtualization
4) Server virtualization
5) Storage virtualization
6) Network virtualization

7. 1) Hardware Virtualization
✔ Hardware virtualization refers to the
technology of consolidating multiple small
physical servers into a large physical
server for the efficient usage of the
processor.
✔ This involves the embedding of virtual
machine software into a server’s
hardware component.
✔ The virtual machines can interact with
hardware without requiring any
intermediary action from the host
operating system.
✔ Hardware virtualization is essentially used
for performance optimization utilizing the
multiple virtual machines that interact
with the same hardware platform.

8. 2) Desktop Virtualization
• Virtual Desktop Infrastructure (VDI) is an end user computing model
enabling clients to connect remotely to their desktop operating system
environment through a central server, which can host multiple of these
desktops for many users at once.
• From their endpoint device, the user can operate and interact with their
virtual desktop as if they were sitting at the PC, and accomplish tasks on
their network even from very far away and without the required
resources present locally.
• For this reason virtual desktops are vital for empowering remote work and
productivity.

9. How Does Desktop Virtualization Works?

10. No matter what kind of VDI deployment is in use, they
do have some common characteristics:
• Centralization: Virtual desktop
infrastructure is always enabled by virtual
machines on a centralized server, whether
locally managed or in the cloud.
• OS Image: VDI always includes an image of
a specific operating system such as Windows
– the most common OS to be virtualized.
• Hosting: Because each desktop is host-
based (through its server), many instances
are stored and used at the same time.
• Constant Connectivity: Endpoints are
unable to display a virtual desktop if they
aren’t connected to the central server, so
users must
remain connected at all times when taking
advantage of VDI.
• VDI Broker: An extra layer in the process
involves what’s called a connection broker,
which orchestrates the acquisition of a
virtual desktop for each user when they
connect, from the server’s available
resources.
• Hypervisor: The hypervisor is a tool that
manages the various virtual machines on the
host server, and ensures that desktops
accessing them have the resources they
require.

11. 3) Application Virtualization
• Application virtualization is a
process that deceives a standard
app into believing that it
interfaces directly with an
operating system's capacities
when, in fact, it does not.
• This ruse requires a virtualization
layer inserted between the app
and the OS.

12. 4) Server Virtualization
• Server virtualization is the
process of dividing a physical
server into multiple unique and
isolated virtual servers by means
of a software application. Each
virtual server can run its own
operating systems
independently.

13. 5) Storage Virtualization
• Storage virtualization in Cloud
Computing is nothing but the
sharing of physical storage into
multiple storage devices which
further appears to be a single
storage device.
• Storage virtualization helps the
storage administrator to backup,
archive and recovery data more
efficiently, in less amount of time
by masking the actual complexity of
SAN (Storage Area Network).
Through the use of software hybrid
appliances, the storage
administrator can implement
virtualization.

14. Benefits Of Storage Virtualization

15. 6) Network Virtualization
• Network Virtualization (NV) refers to
abstracting network resources that were
traditionally delivered in hardware to
software. NV can combine multiple
physical networks to one virtual,
software-based network, or it can divide
one physical network into separate,
independent virtual networks.
• Network virtualization software allows
network administrators to move virtual
machines across different domains
without reconfiguring the network.
• The software creates a network overlay
that can run separate virtual network
layers on top of the same physical
network fabric.

16. 6) Network Virtualization

17. Reason for virtualization`
1. Virtualization helps to scale and manage complexity
2. Virtualization has a limited overhead on CPU and memory
utilization
3. Virtualization makes the safety case easier to demonstrate
4. Virtualization can increase security
5. Virtualization is complementary to OS partitioning
6. Virtualization supports hard real-time automotive
applications
7. Virtualization brings a lot more than separation
8. Virtualization enables low-cost solutions
