Preface

Learning Microsoft Azure is a practical, hands-on book for learning how to build systems for Microsoft Azure. This book is themed around an enterprise case study based on a fictional industrial bakery called Azure Bakery, which spans three business units: sales, production, and supply. The entire system is built on the Microsoft Azure technology that utilizes a broad range of services.

The sales business unit is responsible for selling products to customers through the MVC 5 customer website, where customers can place orders and view their status as the order moves through the system. Products are managed through another administrator website that implements Azure Active Directory authentication. A Windows Phone app with .NET mobile service and Twitter authentication integrated with the customer website allows customers to view the order status on their phone and receive push notifications via the notifications hub when the order status changes and new products are created. The sales system has its own dedicated SQL Azure Database and communicates with the other systems via a Service Bus topic. A worker role is implemented to keep the sales system updated as orders are processed through the enterprise system.

The production business unit is responsible for manufacturing the products for the customer orders and has a worker role at the core of it, which consumes customer orders from the Service Bus topic, enters the orders into the production SQL Azure Database, creates batch schedules to bake products, and allocates stock in the system. Production staff uses an on-premises WPF client application with Azure Active Directory authentication to view batch schedules and manage stock via a Web API 2 service with SignalR hub and Azure Service Bus backplane, allowing client applications to update in real time.

The supply business unit is responsible for picking up and packing orders from the production business unit and delivering them to customers. A worker role consumes orders from the Service Bus topic and stores customer details in a table storage, and automatically creates barcode labels stored in a blob storage. Supply staff interacts with the system via an Enterprise Windows Store app, which is authenticated with Azure Active Directory and has a .NET mobile service backend.

As we're building the system, we learn about the topic we're exploring and apply it to our system with detailed walk-throughs and relevant code samples. There are complete working code samples for the entire system that are broken down chapter-wise.

What this book covers

Chapter 1, Getting Started with Microsoft Azure, gives an introduction to cloud computing and Microsoft Azure followed by how to choose a subscription and signing up for a subscription. We finish this chapter by taking a look around the portal, and then start looking at the different services Microsoft Azure has to offer.

Chapter 2, Designing a System for Microsoft Azure, covers designing scalable, resilient systems for Microsoft Azure by looking at methodologies for breaking systems into subsystems and selecting appropriate Azure services to build them. This process will be applied to design a small system for an independent station that requires a website and a basic administration system; it is then extended to a full enterprise system, where will we introduce the Azure Bakery case study.

Chapter 3, Starting to Develop with Microsoft Azure, gives you the first taste of developing for Microsoft Azure, where you will prepare their development environment with the required tools and sign up for a Visual Studio Online account. We'll create the foundations of the sales customer website and publish it to the cloud, and then set up continuous deployment using the Visual Studio Online Team Foundation build server.

Chapter 4, Creating and Managing a Windows Azure SQL Server Database, creates a database for the sales business unit and builds it using Entity Framework Code First Migrations. This chapter will examine different tools for working with the database from a developer and administrator point of view, and look at options for database backup.

Chapter 5, Building Azure MVC Websites, builds the sales customer website and administrator website, with Twitter authentication for the customer site and Azure Active Directory authentication for the administrator site. We will learn how to apply custom domain names and SSL certificates to Azure websites and learn how to perform Azure AD group authorization in an MVC website.

Chapter 6, Azure Website Diagnostics and Debugging, follows on from the previous chapter, exploring techniques and tools to help diagnose problems and debug Azure websites. We'll look at enabling diagnostics in websites, working with logfiles, and examining application logging and site diagnostics. Finally, we'll look at the Kudu service and remote debugging Azure websites.

Chapter 7, Azure Service Bus Topic Integration, starts with an overview of the Service Bus topics and creates a topic for handling order messaging between the three business tiers. We'll integrate the sales customer website into the topic with a subscription, allowing the newly-created orders to be sent across the system, where they will be collected by the production system for manufacturing, and the supply system for producing address labels and planning deliveries. We'll also create a messaging simulator to allow the topic to be loaded up with high volumes of orders to help test the scalability and capacity of the system. Finally, we'll look at the features in the portal to help us monitor and manage our Service Bus topic.

Chapter 8, Building Worker Roles, gives an introduction to cloud services and creating a worker role. Then, we'll create and run a basic cloud service locally on the compute emulator, and publish and run it in the cloud. The production order processor is created next, which is responsible for receiving orders from the Service Bus topic, saving them to the production database, creating product batch schedules, and allocating stock. Finally, we'll test the cloud service in a scaled deployment using the simulator created in Chapter 7, Azure Service Bus Topic Integration.

Chapter 9, Cloud Service Diagnostics, Debugging, and Configuration, continues on from the previous chapter and covers diagnostics, remote debugging, and IntelliTrace. We'll learn how to deal with configuration changes made in the portal at runtime and implement start-up tasks for performing customizations to prepare the server environment for the service.

Chapter 10, Web API and Client Integration, provides an introduction to the Web API and SignalR with an Azure Service Bus backplane followed by building a Web API service and a SignalR hub, to allow the production management application to interact with the production database and Service Bus topic. The system will be authenticated with Azure AD authentication, allowing production staff to log in to the WPF client application using their Azure AD credentials.

Chapter 11, Integrating a Mobile Application Using Mobile Services, brings the whole system together with the addition of a mobile service and a Windows Phone 8 application for the sales system, which allows users to log in with the same credentials as the customer website, view orders, and receive order updates and product news via the notifications hub. The sales mobile service provides APIs for the admin website and order processor to interact with the notifications hub. Finally, the chapter looks at building an Azure AD authenticated mobile service for the supply Windows Store application to view orders and retrieve address labels from a blob storage created by the supply order processor.

Chapter 12, Preparing an Azure System for Production, is the final chapter, and looks at configuring systems for various environments including production, and creating publishing packages using the Visual Studio Online Team Foundation build server and producing database scripts in order to manage the system deployments in a controlled way by systems administrators or developers. We'll learn how to monitor the different services implemented throughout the book once they are live, and also cover guidelines for publishing web-connected mobile applications.

What you need for this book

You need a good spec machine with Windows 8.1 installed as a starting point. A premium version of Visual Studio 2013 is ideal but not necessary as multiple versions of Visual Studio Express (which are free) can be used instead. You will sign up for a Microsoft Azure subscription at the start of the book if you have not already got one; there are various paid options, but a free 3-month trial is available. To work on Windows Store applications, a Store account is needed, which is covered in Chapter 11, Integrating a Mobile Application Using Mobile Services.

Who this book is for

This book is aimed at .NET developers interested in building systems for Microsoft Azure. Good knowledge of Microsoft .NET is essential; knowledge of building websites, Windows applications, and Windows Phone or Windows 8 applications is helpful but not essential.

Conventions

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: In the website project, open the Views/Home/Index.cshtml file and make some changes to the markup.

A block of code is set as follows:

public class AuthHelper

{

    public static async Task GetCustomer(ServiceUser serviceUser, CustomerMobileServiceContext ctx)

    {

        // Find Twitter Id, of form Twitter:123456789

        var idParts = serviceUser.Id.Split(':');

        var key = idParts[1];

        var provider = idParts[0];

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

public class AuthHelper

{

    public static async Task GetCustomer(ServiceUser serviceUser, CustomerMobileServiceContext ctx)

    {

        // Find Twitter Id, of form Twitter:123456789

        var idParts = serviceUser.Id.Split(':');

var key = idParts[1];

        var provider = idParts[0];

Any command-line input or output is written as follows:

Install-Package WindowsAzure.MobileServices

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: Enter Project name and Description and select the Team Foundation Version Control option (this is the default option), and then click on Create project.

Note
