Advantages of Cloud Computing and Private vs Public Cloud

CLOUD COMPUTING
Question 1.
a)
 Cloud computing is advantageous by storing data in the cloud which makes it cheaper for
data to be restored than storing the same data on a on a device that is physical
(Armbrust,2009).
 Cloud computing happens to be almost the most cost efficient method to upgrade, use
and maintain. Companies used to spend a lot in the purchase of traditional desktop
software and additional licensing fees for multiple users.
 Cloud computing allows for automatic software integration. Cloud users are not required
to do the extra work of customizing and integrating their application according to their
own likings.
 Cloud computing offers the advantage of quick deployment. When one decides to use this
method of functioning, it can start functioning within a few minutes
b)
Public cloud allows its services and resources to be easily accessible by the
public, for example google. Its inexpensive as its resources are made available to a large
number of customers at the same time and provides information from many sources while
private cloud on the other hand allows accessibility only within the
company(Armbrust,2010). It can be achieved by the company itself or managed by a
third party. It allows high level of security and privacy and also provides more control as
an organization manages its own resources and hardware.
Question 2.
a) (Buyya,2009)
1. Determining what an isolated cloud structure will do to the financial plan and money
related stream and additionally deciding the utilization cases for the cloud and making a
procedure for how you will really transfer applications to the isolated cloud.
2. Selecting people to implement which can be the individual themselves, invite
professionals from private cloud vendors, or hiring a consultant to do the implementation.

3. Learning stages of implementation which include, server virtualization, stockpiling
virtualization, obtaining virtualization-based administration devices for observing.
4. Training employees –this is done by involving them in the implementation pf the private
cloud.
5. Buying of new hardware and software to monitor performance and traffic flow.
6 Working with business application gatherings to fulfill their necessities
7. Planning for the likelihood of incorporating with an open cloud supplier as you get ready
to execute a private cloud condition.
b)
The system center uses host groups and VMware pool to create and manage the
private cloud. It contains various components such as the VMM Database, VMM
Management Server, VMM Console and the VMM Library Server. These components
are configured in a manner that they collect data from organizations, store and execute
the data. When requested its made readily available by the service center. Operations
manager is used to monitor all the services deployed in the cloud. Detailed information
including alert notifications and reports are provided to let one know when an issue has
come up. When the issue has happened, one automatically deals with the issue to ensure
that the service is still running and performing efficiently. Application performance
monitoring is configured to monitor the performance and availability of a .NET
application.
Question 3.
a)
System health and performance monitors enable monitoring a great number of
servers within a network. This is very crucial especially where one is dealing with a
largely spread setup of network geographically, for example, MAN OR LAN. Even
though NAGIOS and SCOM monitoring tools deals with that from various directions.

SCOM is used to monitor hypervisors and operating systems by recovering and showing
state, performance and health information of the machines. It is Microsoft targeted at
managing servers and infrastructures of the enterprises, applications and services.
b)
i. Operations manager.
Health check is performed on operations manager as it provides a level beyond
server health of monitoring and also provides the availability of vital applications.
It is therefore a necessary constituent of the IT infrastructure.
ii. Virtual machine manager.
It enables configuration and management of virtualization host, storage and
networking for creation of virtual machines and services.
iii. Service manager.
Allows organizations to control problems and incidents. Deals with operations
such as the Microsoft Operations Framework (MOF) and in the Information
Technology Infrastructure Library (ITIL).
iv. Orchestrator.
Manages the workflow solution for data center. It allows for automatic
monitoring, creation and disposition of resources in the environment.
v. Application controller.
A few applications contain a lot of rationale about the screens to use at various
focuses, which may include summoning certain screens at specific circumstances
in an application.
vi. DPM controller health.
conveys brought together reinforcement of branch workplaces and inside the
server farm, by close consistently securing changed records at the byte-level to an
optional plate, which would then be able to be went down to tape.
Question 4.
a)
