Virtualization

• Virtualization refers to the creation of a
  virtual version of any component. These
  components can be storage devices, applications,
  computer hardware platforms and network
  resources. Virtualization is the technology
  through which multiple simulated environments or
  dedicated resources can be created from a single
  hardware.
• Regardless of the size of the business, it
  contributes majorly to lower IT expenses and to
  enhance efficiency. Virtualization is made
  possible with the aid of a software that enables
  the installation of multiple operating systems on
  a system.
• Virtualization can be of many types. This PPTs
  content focuses on four major types of
  virtualization. These are network virtualization,
  storage virtualization, application
  virtualization and desktop virtualization.

Virtual Machine(VM)

• Any virtual environment that works as a virtual
  system and is equipped with its own memory,
  storage, central processing system and network
  interface that are present on a hardware, is
  referred to as a virtual machine. It can be off
  or on-premises.
• There is a software called hypervisor that
  separates a virtual machines resources from the
  hardware. It also ensures appropriate
  provisioning of a VMs resources. The physical
  machine that is equipped with a hypervisor is
  known as the host machine or host. The multiple
  virtual machines that use the resources are
  called guests.

5
Data Centers

• Any data center refers to a physical facility
  which is used for the purpose of housing
  organizations data as well as their critical
  applications. Every data center is equipped with
  a network of computing and storage resources
  through which shared applications and data are
  delivered. Servers, storage systems, routers,
  firewalls, switches and application-delivery
  controllers are the main components of a typical
  data center.
• Data center space is often provided by web hosts
  along with Internet connectivity for the servers
  that are located in their data center. The next
  slide will touch upon web hosting briefly.

• Whoa! Thats a big number, arent you
  proud?

Web Hosting

• Web hosting is a service that is provided by web
  hosting companies. The required server space as
  well as the necessary technologies and services
  that are needed to make a website accessible are
  provided through web hosting.
• Web hosting can be of many types, such as shared,
  dedicated, reseller, cloud, WordPress, VPS etc.
  Those web hosting companies that provide
  exceptional quality of service are often referred
  to as the Best Website Hosting Company or as
  the Best Windows Hosting Company or as the Top
  Cloud Hosting Company.

Data Center Virtualization

• Data center virtualization involves a data
  centers migration from physical servers to a
  virtual environment with the aid of cloud
  computing technology. Data center virtualization
  enables businesses to run multiple applications
  and operating systems on a cloud-based single
  server. This helps to achieve enhanced efficiency
  as well as increases economies of scale.

Benefits of Virtualization

• Virtualization offers many benefits. These are
  mentioned below, in no particular order.
• Enhanced IT scalability, productivity and
  flexibility
• Overall cost savings, along with a reduction in
  operational and capital costs
• Enhanced mobility with regard to workload
• Reduction in downtime as well as an improvement
  in disaster recovery
• Enhanced responsiveness and swifter provisioning
  of resources and applications
• Automated operations and simplified management of
  data centers
• Better performance and an increase in the
  availability of resources

4 Main Types of Virtualization

• The four main types of virtualization are network
  virtualization, storage virtualization,
  application virtualization and desktop
  virtualization. These will be touched upon in
  more detail in the following slides.

11
Network Virtualization

• This type of virtualization involves a networks
  available resources. In network virtualization a
  physical network is entirely replicated. This
  enables applications to run on a virtual network
  in a way as if these were running on a physical
  network.
• Network virtualization apportions the available
  bandwidth among discrete channels. Each of these
  channels can be secured separately by admins.
  These channels can be assigned and reassigned to
  specific devices and this can be done in
  real-time.
• It ensures greater operational efficiency,
  improves a networks speed as well as
  availability and security.

12
Storage Virtualization

• This is a type of virtualization that uses
  software for the purpose of finding physical
  storage space in multiple devices and
  consecutively forms a single storage device that
  can be used by machines. I/O requests are
  received from virtual machines and physical
  devices by the software. These requests are then
  sent to the physical storages location, which is
  a part of the overall storage facility. This
  pooled storage can be managed from a central
  console.
• Virtualizing a data center usually makes use of
  storage virtualization along with other
  virtualized resources. Its benefits include
  enhanced reliability and better performance, a
  reduction in hardware costs along with
  heterogeneous storage types simplified
  management.

13
Application Virtualization

• Application virtualization enables apps to run
  separately from the devises that access these
  apps. This type of virtualization allows admins
  to install, patch as well as update a single
  version of an app instead of carrying it out
  multiple times.
• The server-based approach involves application
  virtualization. In this approach an application
  runs in a virtual machine and users interaction
  with the application takes place through a remote
  display protocol. Since an application cannot run
  without an operating system, application
  virtualization is essentially desktop
  virtualization. The next slide focuses on desktop
  virtualization.

14
Desktop Virtualization

• The aim of desktop virtualization is to isolate
  the operating system of a desktop from where it
  can be accessed by users. Desktop virtualization
  can be of many types.
• When desktops are deployed as a managed service,
  it ensures swifter response with regard to
  evolving requirements of an organization.
