Task 1: Difference between Cloud Computing and Virtualization. Highlight the
benefits of each and share the comparison.
To most, virtualization and cloud computing can seem as pretty much the same thing
despite both of them having broader definitions which applies for various system types.
Cloud computing and virtualization both are mostly found to be virtual in that they rely upon
pretty much the same principles and models (Rankothge et al., 2015). This does not
necessarily mean that cloud computing and virtualization are one and the same.
Virtualization refers to the technology using which creation of several simulated
network environments can be allowed as well as duplication of available resources out of a
particular hardware system. Applications known as hypervisors connect directly to hardware
systems (Jin et al., 2015). These allow one in splitting of a system to different, unique and
secure system environments called virtual machines or VMs.
Cloud computing on the other hand refers to the approaches and set of principles
which perform computational, network as well as storage based infrastructural resources,
platforms, applications and services for the users all across the network.
Cloud Computing Virtualization
Serves the purpose of setting up multiple
simulated virtual environments out of the
same system.
Serves the purpose of pooling as also
automating virtual resources for on demand
usage.
Used for delivering resources to certain
users for designated use cases.
Used for delivering variable set of resources
for group of users to perform various
activities.

Comes in image based configuration in
virtual drives.
Comes in template based configuration for
integration with company networks.
Built for long term usage generally years. Built for short term usage generally hours or
months.
Comes with higher capital expenses
(CAPEX) and lower operating expenditure
(OPEX)
Comes in two instances:
Private Cloud: High CAPEX and Low
OPEX
Public Cloud: Low CAPEX and High
OPEX
Virtualization can be scaled up Cloud implementations can be scaled out.
Involves stateful implementations Involves stateless integration

Task 2: Evaluation of RAID technology and its different levels. Reflect the
differences of various RAID levels in term of their: architecture, techniques,
operation, and performance.
RAID offers arrays of storage which the operating system or OS sees as logical hard
disks. The RAID technology employs different techniques like mirroring of disks and disk
striping (Yuan et al., 2017). This mirroring copies similar data to one or more drives based on
the RAID configuration selected. Striping partitions of the storage space of every drive to
units that range from a sector of 512 bytes and all the way to some megabytes. These stripes
of the disks then get interleaved and are addressed accordingly.
RAID levels
RAID 0: In this configuration striping exists redundancy of data is absent. This level of
RAID provides maximum performance without any countermeasures to address faults.

RAID 1: This level performs disk mirroring and the configuration can consist of about two
drives for duplication of storage data. No disk striping occurs here. The read performance
