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.

Initializing the configuration of Windows Azure Diagnostics

The Windows Azure Diagnostics module is imported into a role by the specification of an Import element with a moduleName attribute of Diagnostics in the Imports section of the service definition file (ServiceDefinition.csdef). This further requires the specification, in the service configuration file (ServiceConfiguration.cscfg), of a Windows Azure Storage Service account that can be used to access the instance configuration for diagnostics. This configuration is stored as an XML file in a blob, named for the instance, in a container named wad-control-container in the storage service account configured for diagnostics.

The Diagnostics Agent service is started automatically when a role instance starts provided the diagnostics module has been imported into the role. Note that in Windows Azure SDK versions prior to v1.3, this is not true in that the Diagnostics Agent must be explicitly started through the invocation of DiagnosticMonitor...
