Topic 1, Case Study A
Background
Best For You Organics Company is a global restaurant franchise that has multiple locations. The company wants to enhance user experiences and vendor integrations. The company plans to implement automated mobile ordering and delivery services.
Best For You Organics hosts an Azure web app at the URL https://www.bestforyouorgdnics.com. Users can use the web app to browse restaurant locations, menu items, nutritional, information, and company information. The company developed and deployed a cross-platform mobile app.
Requirements
Chatbot
You must develop a cbatbot by using the Bot Builder SDK and Language Understanding Intelligence Service (LUIS). The chatbot must allow users to order food for pickup or delivery.
The chatbot must meet the following requirements:
• Ensure that chatbot endpoint can be accessed only by the Bot framework connector
• Use natural language processing and speech recognition so that users can interact with the chatbot by using text and voice. Processing must be server-based.
• Alert users about promotions at local restaurants.
• Enable users to place an order for delivery or pickup t/y using their voice.
• Greet the user upon sign in by displaying a graphical interface that contains action buttons.
• The chatbot greeting interface must match the formatting of the following example:
Vendor API
Vendors receive and provide updates for the restaurant inventory and delivery services by using Azure API Management hosted APIs. Each vendor uses their own subscription to access each of the APIs.
APIs must meet the following conditions:
• API usage must not exceed 5,000 calls and 50,000 kilobytes of bandwidth per hour per vendor.
• If a vendor is nearing the number of calls or bandwidth limit, the API must trigger email notifications to the vendor.
• APIs must prevent API usage spikes on a per-subscription basis by limiting the call rate to 100 calls per minute.
• The Inventory API must be written by using ASP.NET Core and Node.js.
• The API must be updated to provide an interface to Azure SQL Database. Database objects must be managed by using code.
• The Delivery API must be protected by using the O Auth 2.0 protocol with Azure Active Directory (Azure AD) when called from the Azure web app. You register the Delivery API and web app in Azure AD.
You enable O Auth 2.0 in the web app.
• The delivery API must update the Products table, the Vendor transactions table, and the Billing table in a single transaction.
