2SYSTEM ANALYSIS
Three Best Vendor of Cloud
The health care system is not on par with other sectors in terms of implementing
information technology as a means to maintaining the processes. Almost all of the health care
systems share the same drawback. They heavily depends on paperwork to keep records or for
medical purposes (Kampas, Tarkowski, Portell, 2016). But with the booming information
technological advancement the human civilization is changing rapidly, along with it health care
sector is also evolving by using the information technology as a tool in their day to day
workflow. To make the system of “My Health Record” much more efficient, faster and
automated cloud infrastructure can be integrated to the system. There are many types of cloud
services with service models like IaaS, PaaS and SaaS (Almorsy, Grundy & Müller, 2016).
These types of models can be used as Hybrid clouds, Private cloud, Public cloud and also
Community cloud. There are many cloud providers, of which most famous services are listed
below.
1. Microsoft-
The tech giant Microsoft is probably the most famous tech company of the world. And
this company is considered the best cloud provider by many. Along with the cloud infrastructure
this company also provide Blockchain technology, AI services and also machine learning.
Microsoft provides a robust system with easy to use interface, as well as well-organized
three tier service sectors. The tiers are 1. Personal computing, 2. Intelligent cloud and 3. Business
processing (Gangwar, Date & Ramaswamy, 2015). They provide cloud services to all its
customers including PC owners as well as work computers. Since all applications are shifting
toward web based system, Microsoft is also providing. These services through their cloud system

as well. For business purposes there are services like Sharepoint, Exchange, and Office
Communication Server etc are also provided into the cloud services.
Microsoft also provides design and deployment tools and applications. These services
helps companies to make their system more robust and to perform more effectively. Microsoft
provides services like database system, operation system, programming framework and
languages, various tools (Avram, 2014). The company has a customer centric business model,
they provide a free trial period of 30 days and then subscribe their cloud services.
2. Salesforce.com
The second most famous cloud service provider that can be suggested for “My Health
Record” is the service that the Salesforce.com provides. An American Company, known as
Salesforce provides the service for cloud to all the customers who takes service from them. This
company has mixed the service of cloud to that extent so that the customers are able to maintain
their relationship with the organization (Chou, 2015). The other services that the Salesforce
serves is the spanning sales, analytics, marketing, Internet of Things, commerce, marketing, as
well as communities. The services that the Salesforce provides is the Salesforce. The Salesforce
is tied with Google increase its services in the area of technology.
One of the famous companies known for the service of cloud of is the Salesforce.com.
Many competitive moves are provided by the Salesforce that makes the company unique among
all the companies in that sector (Tung, Richter & Savjani, 2015). The customer usually makes
profit by switching their clod server to Salesforce as the company provides the customers a 50 %
off on subscription if they switch on the cloud server to Salesforce. Recently, the Salesforce is
also offering their customers with SAP. The company also provides ERP (Enterprise Resource

4SYSTEM ANALYSIS
Planning) to their customers with the help of CRM tools. This makes the company to implement
a new service for their customer.
The features that the Salesforce.com provides is a variety of business to its business. This
includes mobile application, marketing, CRM, sales, marketing, etc. There are many services as
well that the Salesforce provides (Toosi, Calheiros & Buyya, 2014). This helps the companies to
keep the contact of the customer for emergency contact. The customers can also avail the service
of cloud from any time they like to poses.
3. Amazon Web Service
The Amazon Web Service provides data centers to the customers and also provides the
cloud service to small companies as well as big companies. Cloud market was firstly started by
Amazon Web Service in previous days for storing the information for the company. The
companies who avail the services of cloud from Amazon can get much advantage that are used
by cloud service to make competition in the market (Kampas, Tarkowski, Portell, 2016). The
main innovation that the AWS provides is the web based modelling for computing to the
companies. The database that Amazon pays is a Web Service as well as provide CloudFront for
delivery of service.
The feature that is included in the service of Amazon Web Service provides is that the
company provides with a service that is extremely secured and is extremely safest platform,
which provides a service that is mainly protected (Hashem et al., 2015). More services that are
provided by the Amazon Web Service are computing power, database service, and networking.
The service that is provided by Amazon is very much cost efficient and is flexible. This service
is appropriate for using by all companies who prefers to use the loud system as its information

5SYSTEM ANALYSIS
technology. Amazon Web Service do not extra cost of installation or expertise for installation as
the process is very easy and is efficient to use. The service that Amazon provides is basically a
static website based service that all companies can host easily. The services are trustworthy,
scalable, as well as flexible. And the services that the Amazon provides is provided for free and
their customer can avail their data from anywhere. There is also no requirement of specific
devices accessing the documents that are stored in the cloud (Rittinghouse & Ransome, 2016).
The services that the companies avail from the cloud of Amazon Web Service is considered as
the best service among all the cloud service.
Review for Cloud
The service of cloud that are provided by different vendors gives many advantages that
the company for which the companies are to switch their server that are cloud based (Botta et al.,
2016). The benefits that are provided by the cloud are as follows.
1. The system of cloud is very effective as well as cost effective. For implementing the
system of cloud, the companies has to spend very less on its infrastructure. If the system id
implemented once, then the cost of maintaining is also very less (Almorsy, Grundy & Müller,
2016). The providers of cloud keeps their service minimal and all companies from small to big
can afford their service with less money investment.
2. The system of cloud can be accessed through many systems, which makes the system
more effective (Assunção et al., 2015). The devices that can access the system of cloud includes
tablets, laptops, mobile phone, IPad and many more. This makes the system faster as the clients
can avail their services from anywhere they like to and at any time.

6SYSTEM ANALYSIS
3. The cloud software require less number of software. For this reason the cloud service
is considered as a cost beneficial service compared to all others service of Information
Technology (Ali, Khan & Vasilakos, 2015). All the software required for cloud are involved in
the network of cloud and the user does not have to pay any money for the license of cloud.
4. The installation process of the software is very easy and the company does not need to
appoint new efficient employees for installing as well as maintaining the cloud system (Bajaj,
Patel & Patel, 2015). Anyone from the existing employees can install the cloud server, and
maintain them regularly only with a little experience.
5. The records of company are kept securely in the cloud. The records are to be kept in
the cloud only for security. This helps the companies to minimize the paper works and provides
the company to execute an efficient workflow.
The advantages that the cloud system provides is not always flawless. There are many
disadvantages that the organizations deals with the implementation of the cloud. The
disadvantages are state as follows.
1. There must be availability of Internet connection for accessing the information of
cloud. The user can avail those data only if the internet is available with the user (Matharu et al.,
2015).
2. The cloud service requires a high bandwidth internet connection for the user to access
all its documents and data. The cloud service cannot use a low bandwidth internet connection for
its accessing.
3. The system of cloud can be slowed down if all the users use them simultaneously.
Sometimes, it can be worse and the system is likely to be in temporary shutdown.

7SYSTEM ANALYSIS
4. The company should look at the security of the data while storing them in cloud. The
company should maintain the security of data when the data are stored in the cloud system
(Rittinghouse & Ransome, 2016).
5. There are some non-negotiable contracts that are provided by some services of cloud
that makes using the cloud system difficult for the organization.
Approach System Development Life Cycle
Advantages and disadvantages of Predictive SDLC
The system which maintain the predictive methodology of System Development Life
Cycle are easily described and clearly understandable. Project requirements should be steady for
this method. In this system model technical risks are lower (Gangwar, Date & Ramaswamy,
2015). This model also provides some disadvantages too. Since this model does not provide
backward process, through plans should be made prior to starting the entire system itself. Once
the process is done there are no turning back.
Advantages and Disadvantages of Adaptive SDLC
The advantages of the adaptive approach of SDLC is it provides the user with time
flexibility (Toosi, Calheiros & Buyya, 2014). Which means the user can add or change additional
functions to the system even after starting the project. The requirements of the project can also
be changed the same way. Implementation is the main focused area in this method. The adaptive
SDLC also have some disadvantages as well (Tung, Richter & Savjani, 2015). This method
contained some technical risk factors. It is a complicated process. Since the requirements can
change afterwards, the budget can also vary.

8SYSTEM ANALYSIS
With keeping all this advantages and disadvantages in mind the recommended approach
for “My Health Record” is the method of Adaptive SDLC. Because in this way the system can be
changed and optimized according to the requirements of the customer.
