Stage 1 Architecture and business flow
The architecture and business flow of an enterprise is defined by the processes and
relationships between them that are required in order to achieve the aim of the system. The
processes are defined at a smaller level to support the entire functionally of the business (Whittle
and Myrick 2016). The smaller process then creates a fully functional system combined. For a
business, the system process can be identified by the business process of real-world scenarios.
The business process of the NoQueue app is given below:
i. After shopping, the user can scan QR codes of the items using the app by themselves to
create the bill.
ii. The user can select or deselect the item from the listed scanned items.
iii. Users can pay the amount using their banking information in the app through a secured
payment gateway.
iv. Users can directly scan the QR code for a shop or bank to directly pay the whole amount
of billed payment.
v. Users can avail available offers or buy gifts-card during the transactions.
Stage 2 Technical Requirements
The technical requirements of a project can be determined by aligning with the business
requirement of the system. The technical specifications identified for the NoQueue Application
are based on the capacity, performance, privacy, and services (Kopczyńska, Nawrocki and
Ochodek 2018). In terms of capacity, the Application should be able to handle a vast number of
users at a time, along with the high volume of generated data. Higher the capacity of the
application system, the higher the response rate will be. Second, the bandwidth of services

provided should support multiple functionalities at a time. Greate bandwidth provides a higher
capacity of connectivities and transmissions along with maintaining the quality of the
information. Third, the security aspects of the application and cloud storage should both be high.
The use of encryption during transmission and storing, along with the authentication process,
should be able to provide such a level of security. There are multiple cryptographic techniques
available to achieve high-end encryption. Lastly, the performance of the system should be high
in terms of computation and process as the system is a real-time system. The computation
process should not be reliable on mobile resources fully. Instead of using mobile resources,
computational activities should take place on the cloud servers.
Stage 3 Design
Network Architecture Diagram
Network Architecture diagram represents the structure of the Network using different
symbols for the devices, network components, and connection between them. It is an ideal way
to document the physical overview of the expected architecture of the real system (Karagiannis
et al. 2014). Implementation of a data center requires the storage, servers, IaaS, and PaaS
components. While the connectivity can be established using the internet and GPS. The web
services provided by the cloud infrastructure can be used by internet-enabled devices such as
mobile phones, tablets, and PDAs. Computers and Laptops are also internet-enabled devices;
however, these are not suitable devices for carrying and using for scan and pay method. The
below diagram represents the connectivity of the wireless part of the system to the backbone of
the wired Network via web services.
