Overview of this book

The Windows Azure platform is Microsoft's Platform-as-a-Service environment for hosting services and data in the cloud. It provides developers with on-demand computing, storage, and service connectivity capabilities that facilitate the hosting of highly scalable services in Windows Azure datacenters across the globe. This practical cookbook will show you advanced development techniques for building highly scalable cloud-based services using the Windows Azure platform. It contains over 80 practical, task-based, and immediately usable recipes covering a wide range of advanced development techniques for building highly scalable services to solve particular problems/scenarios when developing these services on the Windows Azure platform. Packed with reusable, real-world recipes, the book starts by explaining the various access control mechanisms used in the Windows Azure platform. Next you will see the advanced features of Windows Azure Blob storage, Windows Azure Table storage, and Windows Azure Queues. The book then dives deep into topics such as developing Windows Azure hosted services, using Windows Azure Diagnostics, managing hosted services with the Service Management API, using SQL Azure and the Windows Azure AppFabric Service Bus. You will see how to use several of the latest features such as VM roles, Windows Azure Connect, startup tasks, and the Windows Azure AppFabric Caching Service.

Using the Windows Azure Diagnostics trace listener


Windows Azure Diagnostics supports the use of Trace to log messages. The Windows Azure SDK provides the DiagnosticMonitorTraceListener trace listener to capture the messages. The Windows Azure Diagnostics basic logs data buffer is used to configure their persistence to the Windows Azure Table Service.

The trace listener must be added to the Listeners collection for the Windows Azure hosted service. This is typically done through configuration in the appropriate app.config or web.config file, but it can also be done in code. When it creates a worker or web role, the Windows Azure tooling for Visual Studio adds the DiagnosticMonitorTraceListener to the list of trace listeners specified in the Configuration section of the relevant configuration file.

Methods of the System.Diagnostics.Trace class can be used to write error, warning and informational messages. When persisting the messages to the storage service, the Diagnostics Agent can filter...
