Introduction
This assignment we have to write a report on the suitability of the business and the network
entity. In addition, talk about the advantages and disadvantages of moving to virtual cloud
environment. The individual has to relate everything’s to case study, which required cloud
service integration. Cloud computing is computing because of internet. In the past, people may
run application or program from software that is downloaded to a computer or a server but cloud
computing permits people to access the similar kind of application through the internet.

The advantages and disadvantages of moving to a virtual/cloud environment
Advantages of Cloud Computing.
Cost Savings
The very important advantage of cloud computing is that it saving on cost. Cloud computing
save substantial cost on capital with zero in house server stores as well as application needs. The
inadequacy of premise infrastructure as well gets rid of linked operation cost in form of power,
air conditioning and the cost of administrations and hence there is no invested capital to get
worried of (Fischer, 2012). For instance, the cost of fully provision in house server is just 15% to
25% of the server’s TSCO, with the balance of the cost spread over the efficient time of the
server until it is disconnected.
Reliability
With control service platform, cloud computing is very dependable unlike the in house IT
infrastructure. The business will benefit from huge cluster of redundant IT Asset and the first
failover mechanism (Vecchiola, 2013). Is there is failure in the server; hosted application and
service might simply be transited to any existing servers.
Manageability.
Cloud computing ensures that there is improved and simplified IT management and maintenance
features through the main administration of assets, suppliers controlled asset and the SLA backed
contract. IT infrastructure updates and maintenance are removed, as every asset is upheld by the
service provided (Fischer, 2012). The company will just benefit from the web based user
interface in accessing software, application, and service. Devoid of the requirement for installing,
there is guarantee prompt delivery, control, and maintenance of servers
5

Disadvantages of Cloud Computing
Downtime
Cloud service sometimes is overwhelmed and might even come up against technical outage,
which might lead to temporary business suspension. This is more specifically when there is 9%
availability that allow over 332 days of downtime per year. Furthermore, if the internet
connectivity is offline, the business will not be in a position of accessing any applications,
servers of data from the cloud.
Security
Even though the cloud service executes the ideal safety standards, store of data and significant
files on external service provide might lead to risk. With the use of cloud, powered technology
implies that there is need to ensure that the service providers have access to company
information. In the meantime, being a public service will make the clouds service provider
exposed to threat constantly where the compliance rule is not followed strictly.
Limited Control
Because the cloud resource is wholly owned, controlled and supervised by the service providers,
it shifts the least control over to the client who might just control as well as manage the
application, data and service operated above this, not the backend resource. The important
administrative duties like the server shell right of entry, update and firmware control might to be
shifted to the clients or to the end users.
The economic benefits based on the calculation of savings in capital and operating costs
with the use of cloud based computing
Precision Health Care Ltd will save on cost in moving to cloud based computing since;
6

Lower power costs
With the use of cloud computing, the precision health ltd will save on power consumption cost
and improved hardware usage. This would imply that there is efficiency in power utilization
since, idle server consumes a lot of power, which is a loss to the business. In this regards, the use
of cloud computing will make the business incur less cost used as compared to having their data
center is expensive to maintain and run.
Lower people costs
The personnel cost is normally the biggest incurred by the business. When the precision health
ltd uses good IT personnel, their salaries, benefit, and other employment cost will outweigh the
cost of hardware and software (Schulz, 2011). When precision health ltd shift to cloud based
computing, some cash used to pay for the service will be used to pay for provider personnel cost
which is just a small amount as compared to I house IT management.
Zero capital costs
If precision health is to run its own servers, the business will be looking upfront capital cost.
However, with the use of cloud based computing, funding this capital venture is another person’s
problem. For instance, if the precision health service runs the servers itself, the accounting
wizard will do their amortization magic, which will make the cost appear to be spread over the
useful life of the server. However, the cash must come from somewhere, hence it is cost that
cannot be ventured in the business either reach cash or a line of credit.
How Virtualization or cloud technologies improve business continuity
Virtualization is mainly entrenched in the plans of IT leaders. Like many business, it is
susceptible to cost saving. Virtualization will improve business continuity and resilience and will
7

aid in disaster recovery plans. Virtualization allows share, replication, and backup of all kind of
images and the amount of work to be done. These images might then span worldwide data
centers based on the requirement soft business.
Virtualization depicts the biggest impact in business continuity and disaster recovery (Zomaya,
2011). The disasters that affect the IT resource have depicted some threat to the operations and
the long life of the business. The impact of unplanned use might deliver significantly disastrous
impact, from loss in revenue to complete business failures. This risk will increase with the
intricacies of the operating system, network improvement an extra critical application.
With the use of server virtualization, a point perfect solutions will be providing, there will be
reduced on cost whilst being more effective unlike the old model of preserving system uptime
and the data integrity. Virtualization in reality ensures that the information resource will keep on
being accessible any time.
Using the virtualization to act as reducing backup server in replication based high availability
business situation ensure that the use of the technology is not a financial burden to the business.
The four-phased methodology designed
Assess
There is need to identify the objective and developing the firm comprehension of the advantage
of virtual infrastructure solution will offer to precision health limited. The comprehension of the
potential business effect of virtual infrastructure from all appropriate perspective inclusive of
financial, organizational and regulatory, taking into account the policy, process and constraints
specific to precision health limited (Vecchiola, 2013). There is need to ensure that there is a
detailed assessment of the current servers when applicable and provide an option design for the
virtual the infrastructure in the basis of the unique client’s needs.

Plan
Designing a virtual infrastructure solution that complies with the specific client needs identified
in the Asset stage is important. A comprehensive VIM Blueprints as wells VIM testing plan for
developing the selected virtual infrastructure solutions must be produced (Zomaya, 2011). Also a
production of VIM for developing the VIM project plan for tracking the individual duties,
milestone, and constraints that affect the delivery of the selected virtual resources solutions.
Build
Assembling and configuring virtual infrastructure solutions with the use of VIM Blueprint will
be important in this stage. Precision health ltd must leverage the VIM test. Planning to validate
that the solution compliance with the business requirement as well as designing criterion and
providing the outcome in VIM test report (Fischer, 2012). A preparation of VIM management
manual for the site unique guidelines and for the daily management and maintenance of the
virtual infrastructure solution will be important at this stage.
Manage
Precision health ltd must guarantee that ongoing maintenance as well s operation triumphant is
practiced. This is made possible by controlling the virtual resource’s lifecycle (Schulz, 2011).
Enabling the monitoring and maintenance of the system with the use of VIM management
manual.
Evaluate Hybrid cloud solutions
For Many years, cloud computing has been focus on IT verdict makers and corporate bean
counters, but stern safety awareness has been reluctant to shift their data as well as their
workload to cloud. The underlying technology for cloud service exist for the use with the
9

business, the hybrid cloud which is new model of cloud computing is achieving a foothold in
business
Adoption of the Hybrid cloud is a strategic imperative, which ensure that business IT deploys it
on private cloud, whilst ensuring provision of alternative to deploy the workload much better
suited to public cloud like the big data (Vecchiola, 2013). Furthermore, the aim is to ensure that
there is a flawless transition from private to public cloud and between public clouds. At present,
hybrid cloud is almost in the development stage and is at an early phase of adoption. The main
business forces being hybrid cloud strategy is the growth in the value of application to the end
user and the business. As a result, Hybrid cloud project require a buy in and leadership as
business plans with focus on applications and clear longer milestone and objectives for every
phase with an anticipation of comprehensive planning and fixed re-appraisal.
The public and private cloud in a hybrid cloud layout is the unique as well as autonomous
constituent. This permits business to store their data on the cloud, whilst retaining the capacity to
leverage computational infrastructure from the public cloud to run the application that entirely
depend on this data. This will ensure that the threat to data is minimal since they are not storing
sensitive data for long on the public cloud constituent.
It is important to comprehend that the idea of hybrid cloud is not just linking any server to the
public cloud provider and considering at as hybrid. The private resource should run some sort of
cloud service like Nemakiware, which an open source enterprise content management software
stack on the basis of interoperable CMIS guidelines (Fischer, 2012).
The benefits of going hybrid
The advantage of hybrid cloud model is having on building, personal resource that is accessible
directly. This will reduce access time and latency as compared to the public cloud computing.
10

With threatening risk of the integration of internet service providers at the business level in US,
the exiting hesitant of net impartiality and the risk between internet service providers and the
service provider depend on the correct functioning of the internet. Failure that may bring down
the operation of the business is risky (Zomaya, 2011). Another advantage of Hybrid cloud model
is the capacity of having in house computational that may provide support tom the average
workload forms the business whilst retaining the capacity of leveraging the public cloud for the
failover situation that the workload surpasses the computational potency of the private
constituent. This will provide the benefit of paying for extra computational time just when the
resource is required. For the business that depict milestone throughout the year in which high
than normal computation time is required (Tax period, for instance), goes beyond the public
cloud to be cheap proposal unlike building infrastructure that is redundant for many years.
Where Hybrid will pose a challenge
Even though hybrid cloud provides an assortment of benefits over the public cloud, it still suffers
from similar privacy and safety threats that spate the famous point of view of the public cloud
platform providers. Permitting information to be transported across the network that might be
subject to third party interference, too much business, needless and irresponsible safety risk.
Furthermore, Hybrid cloud and public cloud is a poor fit for a situation in which the data
transposition on both end of the cloud is a mission vital operation that is responsive to stoppage
from transporting data across the network and the latency in ping time.
A business that has budget constraint for the IT department cannot afford a rollout of hybrid
cloud solutions. The real expense of the servers on private end of the scale so as one may
anticipate of rack of server’s hardware. A significant and the requirement of the small business to
11

have same IT financial budget might likely to be sufficient with the use of service of the public
cloud provider (Zomaya, 2011).
The users of hybrid cloud
Hybrid cloud technologies are mainly used by healthcare industries since they need to depend on
data between healthcare providers as well as the Insurance firms for many patients are an off
duty. Adherence with the health insurance operability and Accountability act is policy
difficulties since compartmentalizing data to adhere with the Act with non-disclosure protection
heath data commands permission setting extensively. The hybrid cloud is normally used in the
financial sector specifically when nearness is vital and physical space is close to trading floor.
Traders are pushed through the private infrastructure and running analytics on the trade from the
public, cloud resource will significantly reduce the amount of space required for the sensitive
duties of making the trader order (Fischer, 2012). This is important for the data safety asp.
Trusting this data to the public cloud providers is the risk that might expose the whole
underpinning of the business.
Why it is a good idea
With use of Hybrid, cloud may greatly guarantee connectivity at work. Furthermore, other than
managing the files, business should incorporate with much business process like the internal
messaging, development, business intelligences well as analytics. Public cloud does not
incorporate within house hardware (Schulz, 2011). The tool like printers and scanners might be
burden to the adoption of public cloud. Instead, there is need to isolate the mission vital tool
form the rest of the business network and hence with the use of private cloud constituent may be
very effective. Using hybrid cloud model will ensure that the IT decision makers depict more
12

power over the private and public constituents unlike suing a prepackaged public cloud platform
more specifically for business content management.
Conclusion
After examining the benefit and limitation of cloud computing, the general conclusion from the
study is that the adoption of the Hybrid cloud might be efficient plan for a broad assortment of
business that depict a tight pressure on safety or special physical existence demand. Even though
there is greatly reduced threat with hybrid cloud model, permitting access from public cloud
depict some serious threat of insecurity or being medium of data harvest which evident in many
public network administrations. Whilst the upfront cost of hardware for the private constituent of
hybrid cloud being very high, the control by IT department over the hardware selection a well s
system design for the private constituent provider an invaluable approach to handling a standard
workload with explode compute offload to the public cloud which might be a strategic
welcoming plan.
