When the modules are loaded, they're inserted into the ASP.NET processing pipeline in order to redirect the unauthenticated requests to the claims issuer, handle the reply posted by the claims issuer, and transform the security token sent by the claims issuer into a ClaimsPrincipal object The modules also set the value of the HttpContext.User property to the ClaimsPrincipal object so that the application... defines the aExpenseweb role It contains the connection strings that the role will use to access storage and details of the certificates used by the application The application uses the DataConnectionString to connect to the Windows Azure storage holding the profile data, and uses the DiagnosticsConnectionString to connect to the Windows Azure storage for saving logging and performance data The connection... Adatum can't afford to run as many servers as are needed during peak times because this hardware is dormant the rest of the time If these applications were located in the cloud, it would be easy to scale them depending on the demand Another goal is to expand the ways that users can access Adatum's applications Currently, applications are only accessible from the intranet Publishing them to the Internet is... "Getting it to work in the cloud. " Optimizing the application for the cloud and exploiting the features of Windows Azure will come later Your decision to move an application to the cloud should be based on clear goals and requirements Adatum identified some specific goals to focus on in this first phase The aExpense application in the cloud must be able to access all the same data that the on-premises... including local compute and storage emulators that run on the development computer This means that you can write, test, and debug applications before deploying them to the cloud The tools also include features to help you deploy applications to Windows Azure and manage them after deployment Markus says: You can build and test Windows Azure applications using the compute and storage emulators on your development... describe the use of queue storage Chapter 6 of the guide "Developing Applications for the Cloud" and the associated sample application, and Lab 4 in the Hands-on-Labs for that guide, describe the use of table storage (including data paging) and blob storage in multi-tenant applications Chapter 2 of this guideand Chapter 6 of the guide "Developing Applications for the Cloud" , the associated example applications, ...

Studio, to write their applications. In addition, the Windows Azure SDK includes the Compute Emulator and the Storage Emulator. Developers can use these to write, test, and debug their applications. applications locally before they deploy them to the cloud. There are also tools and an API to manage your Windows Azure accounts. This book shows you how to use all these tools in the context of a common. existing applications to the cloud. Developers familiar with .NET and the rest of the Microsoft platform will be able to use their existing skills to quickly build or move existing applications to
