1. Software Architecture
The Pinsiri Hospital has LAN based system which is not appropriate for services to
customers or patients. The hospital wants to update their system so that the updated
system can reflect the advances information and communication technology. To
convert the LAN based software into legacy software we have to work with proper
software architecture. Software architecture plays a vital role in success of business.
Some software architecture is described as follows which are followed by the Pinsiri
Hospital to convert the LAN based software into legacy software:
1.1 services oriented Architecture
The services oriented architecture is a type of software architecture in which the
services will run independently without relying on any other service in the system.
The new system is being developed by ASP.NET framework and it using Azure cloud
environment to host the service application so it become much easier by using
service oriented architecture. This architecture for the software implementation
provides an expandable and easy solution. It has loose coupling like web API services
and Azure cloud services. Thus this is the better software architecture that can be
used by the software.
Drawback
The services oriented architecture also has some drawbacks or verdicts such as
encryption is necessary in these applications to enhances security of application.
1.2 component oriented Architecture
The component oriented architecture is based on components. There are no needs
of writing from the scratch. This is software architecture in process works on
component which are already present in with system without makes any changes
such as writing the classes. There are many benefits of component oriented
architecture such as reusability of component, reuse a compliment without making
changes. In component oriented architecture there are so easy to replace the
components. Thus component oriented architecture is good for the software’s.
Drawback
The component oriented architecture also has some drawbacks such sometimes
there are difficult to remove the component from the application because it became
the part of the application. There are dependencies between the components in this
architecture which makes the system unmanageable.

1.3 client server architecture
The client server architecture is another type of software architecture which is
commonly used by different type of software to achieve some standardization. In
this architecture all sensitive data will be located at server and client data in this will
be available as per the demands on the customer on some particular time. This is
software architecture which works in two parts or layer on is client and another is
server.
Drawback
The client server architecture of software application also has some drawbacks such
as it provides a distributed range of the system to hospital and sometimes the
clients requests increase at high level which leads to system unresponsive or
crashes.
2. Architecture comparison
The architecture that we have used in development of software for Pinsiri hospital is
Azure cloud database which is providing the good management for hospital application
to show advance information and communication technology. We are making
comparison here between Microsoft Azure cloud service and Amazon cloud service
which are described as follows:
2.1 Microsoft Azure cloud services
The Microsoft azure is cloud based environment which are used to host the web
applications, database services and web services. This environment provides us a lot
of benefits such as better management for web and API apps, high availability of
mobiles and auto scalable deployment for applications. If we are using Microsoft
azure cloud then we don’t have any need to manage the servers. Some other
benefits of Microsoft azure services are described as follows:
 It is cloud platform which is available on a reasonable cost with better
facilities so it gives the benefit of cost saving.
 The people are worried sometimes by thinking about the security of data on
a cloud platform from cyber crimes but Microsoft azure gives a better
security to data and this is one of the main benefits of azure cloud platform.
 Azure has different things for different type of applications such as Azure
web apps for application service for web applications and Azure API apps for
application services to run web API.
 This is a highly scalable database which is easy to understand.
 The Microsoft Azure cloud service has block chain application service
 The Microsoft Azure cloud service also provides the message hub services.
 It does not provide any automation manager or business rules services.

2.2 Amazon Azure cloud service
Amazon was first cloud based services which are introduced in 2004 as cloud
computing solution. This is increasing their services since starting. The Amazon is
one of the expensive cloud services as compare to other cloud services such as
Microsoft azure cloud services. The Amazon has different storage perspective it has
a nice verity of active documentation in different form such as webinars, sample
code and libraries. Amazon has a good discussion forum for their developer to
provide the regular and useful information. Amazon azure cloud services are also
described as below in details:
 Amazon azure cloud service does not have block chain application services.
 It also provides message hub services.
 It does not provide the cloud automation manager and business rules
application services.
Thus this is the whole comparison between Amazon azure cloud service and
Microsoft Azure cloud services.
3. Migration strategy
There are many cloud services which are provided by different companies or
organization such as IBM cloud services, Microsoft Azure cloud services and Amazon
cloud services. The migration strategy must be follow up by different facilities and
strategies are described as follows:
3.1 suitability Analysis
The application quality must be good and strategy should be relaxing, and well
architecture. The suitability of the application is also depends on component based
architecture and another type of software architecture. The application for Pinsiri
hospital should be good and must have a reduced time and cost.
3.2 Stability Analysis
The application should be stable enough according to the requirements and must
contains all security aspects such as application should not have any proper draw
backs which will reduced the stability of application. The software for hospital
should be stable enough to connect with advance information and communication
technology.
3.3 Security Analysis
The software should be at better cloud so that we can create a secure application
and does not contain any threats that can break the security of application. The
Hospital software should be located on a good cloud on which we can ensure about
the security of data on cloud from cyber crimes. This analysis is more necessary

because in case on cloud based application it is necessary to think about the security
of data on cloud.
Thus these are the migration strategies for Pinsiri hospital software which can
overcome the disadvantages of current system which is based on LAN.
4. High level analysis and design
The high level analysis and design are used to explain the architecture of software.
These are used to understand the complete overview of system. There are mainly two
types of design for software architecture named as high level software architecture and
low level software architecture. These include the structure of complete software with
their front end, process and backend database. Some types of high level design and
analysis are described as follows:
4.1 UML
UML stands for unified modeling language which is used to show the complete
details about software. There are different types of UML diagram such as class
diagram, Activity diagram, component diagram, sequence diagram, state chart
diagram, collaboration diagram, use case diagram and deployment diagram. Each of
these diagram describe a different thing about software such as class diagram
describe used to define all classes which are created for application and sequence
diagram are used to describe sequence of events in application.
4.2 Object oriented design
Object oriented design is a phase of application software which is used to complete
the software in an easy and systematic way. It defines a realistic view of software
with respect to objects. This is better way to develop software of any requirements
because in this we have a good design to fulfill over all requirements of application.
4.3 Object oriented analysis
The object oriented design must have an object oriented analysis to check that is
meeting to all requirements or not. Object oriented analysis should be done at least
one time after complete the object oriented design.
Thus all these are necessary tips for software high level design and analysis.
5. Report and overview
Thus this is a business report for Pinsiri hospital software that can overcome all drawback of
already exist software which is based on LAN software. This report provides a better way to
know about the software architecture which can be used to implement in software such
client server architecture, component oriented architecture, and service oriented
architecture. This report also contain strategy migration and suitability, scalability and
security analysis in this and it also contains high level design and analysis and UML, object
oriented design, object oriented analysis in it. This business research report also providing a

brief comparison between Microsoft Azure cloud services and Amazon Azure cloud services.
Thus this is the whole description and overview about this business research report.
