Topic 4, Adventure Works Cycles

General Overview

Adventure Works Cycles is a travel agency for cycling enthusiast. In recent years, Adventure Works Cycles has begun renting exotic cars to its clients. You are developing a new web application that will provide Adventure Works Cycles customers with the ability to locate and rent exotic throughout the world.

Application Overview

The web application will be hosted in Azure. The application will provide users with the ability to search for a car by using advanced filtering options, such as the car brand, model, year, and price. All of this information will be stored as strings and will be displayed as drop-down lists.

The brand and model lists that will be displayed on the home page of the web application will be retrieved from Windows Communication Foundation (WCF) services hosted in the on-premises environment.

The home page will be named home.aspx and will be developed by using Microsoft ASP.NET MVC. The business logic will be developed by using ASP.NET Web API.

The MVC front-end layer and the Web API will communicate by using JSON. The business logic will have a call to an assembly named CarBusinessLogic.dll.

For responding, you are creating a worker role named ReportApp in Azure that will collect data from all of the searches made by using the web application. The application will communicate with ReportApp by using messages.

Requirements

Security Requirements

Adventure Works Cycles identifies the following security requirements for the web application:

– The Web API must only accept one data format.

– The CarBusinessLogic.dll assembly must be strongly-named.

– Communication between the on-premises WCF service and Azure must be encrypted.

Logging Requirements

In the Web API, you plan to create a controller named CarController. Before any action in CarController is executed, the following line of code must execute first.

Debug.WriteLine(“pre-processing logging”);

Performance Requirements

Adventure Works Cycles identifies the following performance requirements for the web application:

– After the initial deployment, any changes to the business logic of the Web API must cause minimal downtime to the web application in the production environment.

– The action in the Web API that returns the car brand must be asynchronous, while all other

actions must be synchronous. -When home.aspx is displayed, the rendered page must be cached for 10 minutes.

– The web application will be deployed to multiple instances.

Financial Requirements

ReportApp will shut down every night.

However, data from the searches performed during the night must still be collected.
