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.

Implementing custom logging

Windows Azure Diagnostics can be used to persist third-party log files in the same way it persists IIS logs, failed request logs, and crash dumps. These are all configured through the directories data buffer.

The directories data buffer comprises a set of data sources. These are instances of the DirectoryConfiguration class that exposes the following properties:

Container
DirectoryQuotaInMB
Path

A data source maps a path in the local file system with a container in the Windows Azure Blob Service. The DirectoryQuotaInMB reserves a specified amount of space in local storage for the specified data source. A scheduled transfer period is specified at the level of the directories data buffer. The Diagnostics Agent persists to the configured container any files added to the specified path since the last transfer.

In this recipe, we will learn how to use Windows Azure Diagnostics to persist custom logs to the Windows Azure Blob Service.
