Project Description
 Creating a web site that will connect to
Amazon Web Services and successfully draw all the music products available on the
Amazon Server
 Users are able to search our web site for music products which connects to Amazon using web services, and purchase products through Amazon’s shopping process

Project Description (2)

Users are able to view our “Top Ten” searches (what people are looking for), which we are tracking in our MySQL database
 Users are able to sample mp3 music on our web site, using the MP3 widget

Project Design/Requirements



For this project, the team decided to use agile software development with rapid prototyping
Considering the fact that our requirements frequently changed and evolved throughout the project life-cycle, agile methods were the most well suited for the task at hand
Project was frequently adapted to the business needs and allowing timeframe, where teamwork was constantly promoted to create balance between requirements and deliverables

WAR File


The code was distributed between the developers in a war file (web application archive)
War file contained our JUnit tests, Java server pages, HTML pages, Servlets and Java classes, xml files

Amazon Web Services



One of the requirements for this project was to use Amazon Web Services (AWS)
AWS is a collection of services offered from
Amazon via the Internet
For our project we used:



Amazon Elastic Compute Cloud (EC2)
Amazon Widgets
Amazon Associates Web Service (A2S, formerly Amazon E-Commerce Service or ECS)
4/10/2020

Amazon Elastic Cloud (EC2)
14
 Amazon Web Service that allows users to rent computers and install their own applications on them
 For our project AWS was donated to NJIT, so we as students can gain experience in cloud computing
 Amazon virtual server is monitored with
Xen system
4/10/2020

EC2 continued
15
 XEN system is virtual monitor that allows for several operating systems to be installed on the same computer hardware
 XEN is structured with hypervisor, which lies in the most privileged layer
 Hypervisor monitors the operating systems installed in the upper layers across the physical CPUs
4/10/2020

16
EC2 continued
 Currently supported operating systems are
Solaris, Linux and NetBSD (Unix derivative OS)
 For our project we used a Linux operating system
4/10/2020

Amazon Associates Web
Services (A2S)
17
 Part of the Amazon Web Services
 It is a application programming interface
(API) that can be accessed with SOAP or
REST protocols
 For our project we used SOAP protocol to access the web service. We chose SOAP because Amazon SOAP is more mature and well documented vs REST
4/10/2020

18
Amazon Associates Web
Services (A2S)
 A2S allows developers to retrieve information from Amazon’s product catalog, including images, product descriptions, reviews; and interfaces with shopping carts
 For our project we decided to retrieve information on music products available in
Amazon’s catalog
4/10/2020

Amazon Widgets
19
 Part of Amazon Web Services
 Customizable elements (via web interface) that users can deploy to their web site to feature products from Amazon’s Catalog
 For our project we used Carousel Widget, and Mp3 Widget
 For the widget to work we need JavaScript and Flash enabled

Screenshots from the working project cont.
 Previous slide provides a view of the searched results from the Amazon’s product catalog in the left column when the user on the web site typed justin timberlake in the search box
 Note that on the right column justin timberlake is displaying a count of 6 searches in the music category. This shows that justin timberlake was searched 6 times on our web
22 site in the music category

Conclusion
 Controlling an unpredictable project is a huge responsibility. Quality team work is especially important when using a agile software development approach for the project, because everyone’s work is dependent upon fellow team members. As an example, frequent communication between agile team members plays a vital role in the success of the project's longevity

Conclusion cont.
 In our project, we played the role of both, the customer and the developer, and our adaptation to requirement changes were easier than typical real world projects, where the customer will probably want to stick to the original idea and the developers will have to make sure that those requirements are met
(depending on budget and resources available for the particular project)
34

Conclusion cont.
 As any other project, time restrictions played an important role in our project and were the main reason for our requirement changes.
 Example: We originally decided to implement our own shopping cart, but because of time restrictions of the project, we changed the requirement and decided to use Amazon’s shopping cart instead
