SYSTEM ANALYSIS AND DESIGN
Introduction
The common wealth government of Australia will be launching a ‘My Health Record’
system. This system will provide a secure online summary of the individual’s health information.
The system will be designed in such a way that the users can control what goes into the health
record system. However, in order to protect the security and the confidentiality of the data and
the information that is stored in the health record system, it is essential to properly identify a
correct vendor that will be suitable for providing a cloud solution (Garg, Versteeg & Buyya,
2013). The report further reviews the strengths and weaknesses of cloud based solutions and
whether it will be appropriate to use cloud solutions for the storage of data in cloud. The pros
and cons of using predictive and adaptive SDLC approach are further discussed in this report.
1. Vendor Selection
My Health Record system will be making use of the cloud based model in order to store
the data of the patients. This is decided since the use of cloud increases the accessibility of the
data and increases data security as well. It is essential to choose vendors that will be able to
provide cloud solutions which will meet the requirements of the information system. The three
cloud vendors that are chosen for the purpose are Microsoft, Amazon and IBM. The features of
cloud based solutions that are provided by each of these cloud vendors makes them suitable for
the requirements of the project that deals with development of “My Health Record System”.
1.2. Microsoft
Microsoft is one of the leading cloud vendors across the globe. It provides solution to all
the three layers of cloud , which are IaaS, PaaS and SaaS. The different features of this cloud

2. Review of the Cloud Approach
The choice of the cloud approach is to be evaluated from the options of public, private
and hybrid cloud (Zheng et al., 2013). It is essential to consider which cloud environment will be
suitable for deploying the ‘My health Record System’. The choice of public cloud cannot be
considered as one of the significant aims of the project is to maintain the privacy and
confidentiality of the data which will not be maintained by the public cloud environment (Sen,
2015). This is because the data can be publicly acessed which cannot be allowed in case of My
Health Record Project as the confidentiality of the patients’ data is to be maintained. Private
cloud on the other hand provide a robust security option to the clients as the data stored in private
cloud cannot be accessed by any unauthorized person (Jadeja & Modi, 2012). However, the cost
of implementation is very high and the stored data will have a very restricted access. Therefore

SYSTEM ANALYSIS AND DESIGN
the choice of private cloud environment will not be appropriate as well. For this project, the
hybrid cloud environment is proposed. The choice of the hybrid cloud environment is
appropriate for this project since it offers a mix of both public and the private cloud (Li et al.,
2013). The much needed security feature of offered by the private cloud and the public cloud
helps in easy data accessibility. Therefore the choice of this environment is appropriate. The
strength and weakness of the hybrid cloud environment are as follows.
Strength
The strengths of using a hybrid cloud environment are as follows (Wang & Jia, 2012)-
1. The use of hybrid cloud environment offers a robust security options for the data stored
in the system (Li et al., 2015). This is possible as the hybrid cloud offers a private cloud platform
that maintains the security and the confidentiality of the data.
2. The hybrid cloud environment provides more opportunity for innovation as large
capital expenditure is not required for modelling of the new services. The infrastructure cost is
considerably reduced in hybrid cloud environment. Therefore, the use of hybrid cloud provides a
cost effective solution as well.
3. Hybrid cloud environment offers increasing scalability which makes it suitable to
consider for this project.
4. Improved connectivity is another advantage of using hybrid cloud as it ensures
maintenance of proper bandwidth for improving the performance of the system.

SYSTEM ANALYSIS AND DESIGN
There are certain weaknesses associated with the use of hybrid cloud environment which
are as follows-
1. Major security issues might arise while switching between the public and the private
cloud environment.
2. The cost of implementing the system in a hybrid cloud environment is more than a
public cloud environment.
3. The dependency on the infrastructure that is provided by the cloud vendor is another
major weakness in hybrid cloud.
4. The networking associated with the set up and use of hybrid cloud is quite complex.
The above points discuss the strengths and the weaknesses of using a hybrid cloud.
However, the security weakness can be eliminated by enforcing access control in the system.
3. SDLC Approach
In a predictive SDLC approach, it is assumed that the project is planned and developed
well in advance and the project will be developed according to the project plan. This type of
project implementation approach ensures that the project is completed within a scheduled time
(Balaji & Murugaiyan, 2012). The Adaptive SDLC approach on the other hand is applied to the
projects where the project requirements are not clear and the project might expect certain
changes in the implementation phase. The advantages and disadvantages of both predictive and
the Adaptive SDLC approach is to be evaluated in order to understand which approach should be
chosen for the My Health Record Project.

SYSTEM ANALYSIS AND DESIGN
Pros
The advantages of predictive SDLC approach are as follows-
1. Clear definition of the project objectives is possible with the use of predictive SDLC
approach and therefore, the process of risk identification and risk mitigation becomes easier
(Mahalakshmi & Sundararajan, 2013).
2. The process of project implementation follows a sequential approach and therefore, it
is possible to implement a project within a scheduled time.
3. It is easier to measure the project progress in predictive SDLC.
Cons
The disadvantages of using predictive SDLC in a project are as follows-
1. The scope is fixed so no improvement in the project is possible.
2. Since the testing is done at the end of the project, fixing of the bugs becomes quite
difficult.
3.2. Adaptive SDLC
Pros
The advantages of using an adaptive SDLC approach is discussed below-
1. There are no fixed requirements of the project and therefore, it is easier to implement
changes in the project even during project execution
