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 serve stores as well s 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.
Reliability
With control service platform, cloud computing is very dependable and content unlike the in
house it infrastructure. The business will benefit from huge cluster of redundant IT Asset and
also the first failover mechanism. Is there is failure in the server; hosted application and service
might simply be transited to any existing servers.
Manageability.
Cloud computing ensure 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 enjoy web based user interface in
accessing software, application and service. Devoid of the requirement for installing and SLA to
guarantee prompt delivery, control and maintenance of the TIM services
Disadvantages of Cloud Computing
Downtime

Cloud service mat be overwhelmed and might even come up against technical outage which
might lead to temporary business suspension. 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 thought 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 mean time, being a public service will make the clouds service provider
exposed to threat constantly.
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 s 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;
Lower power costs
With the use of cloud computing, the precision health ltd will save on power consumption cost.
Improved hardware usage would imply that there is efficiency in power utilization. Idle serve

consume a lot of power which is loss to the business. In this regards, the use of cloud computing
will make the business incur less cost of energy used unlike incurring your won data centre.
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. But
with the use of cloud based computing, the funding this capital venture is another person’s
problem.
How Virtualization or cloud technologies helped business continuity
Virtualization is mainly entrenched in the plans of IT leaders. Like many business, it’s
susceptible to cost saving. Virtualization will hence improve business continuity and resilience
and will aid in disaster recovery plans. Virtualization permits the share, replication and backup of
all sorts of images and workload. These images might then span worldwide data centers based on
the requirement soft h business.
Virtualization depicts the biggest impact in business continuity and disaster recovery. 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 applications.

With the use of server virtualization, a point perfect solutions will be provide, there will be
reduced ion 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 to create a range of virtual infrastructure solution
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. 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 clients needs.
Plan
Designing a virtual infrastructure solution that is in compliance 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. Also, a
production of VIM for developing the VIM project plan for tracking the individual duties,
milestone and constraints that impact 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 a well as designing criterion and
providing the outcome in VIM test report. 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. 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 have 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
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..
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.
With threatening risk of the integration of internet service providers at the business level in US,
the exiting hesitant of net impartiality and the lobbing of 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 are 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 not work
Even though hybrid cloud provide an assortment of benefits over the public cloud, it still suffer
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 3rd party interference, to 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
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 is mainly used by healthcare industries since they need to depend on
data between healthcare providers as well as the Insurance firms for many patients is a off
putting duties. 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
power over the private and public constituents unlike suing a prepackaged public cloud platform
more specifically fore business content management.
Conclusion
Adoption of the Hybrid cloud might be efficient pan for a broad assortment of business that
depict a tight pressure on safety or special physical existence demand., even thought 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.
