Cloud Design Patterns
About the Example
|
This document describes the External Configuration Store Pattern example from the guide Cloud Design Patterns (see http://aka.ms/Cloud-Design-Patterns).
Before you start
Ensure that you have installed all of the software prerequisites. For details see the Release Notes.
The example demonstrates operational aspects of applications running in Windows Azure. Therefore, you will need to use the diagnostics tools in order to understand how the code sample works. You must ensure that the web and worker roles in the solution are configured to use the diagnostics mechanism. If not, you will not see the trace information generated by the example.
About the Example
This example shows a mechanism for storing configuration settings in an external store instead of using configuration files. In this example, settings are stored in Windows Azure Blob Storage. The blob containing the configuration information is monitored by an instance of the ExternalConfigurationManager class. When the ExternalConfigurationManager object detects a change in the configuration store, it notifies the application of the change.
Running the Example
This example can be run only in the local Windows Azure emulator.
