External configuration store pattern

This Azure cloud architecture pattern diagram template was created on the base of figure in the article "External Configuration Store Pattern" from the Microsoft Developer Network (MSDN) website.
"External Configuration Store Pattern.
Move configuration information out of the application deployment package to a centralized location. This pattern can provide opportunities for easier management and control of configuration data, and for sharing configuration data across applications and application instances. ...
The majority of application runtime environments include configuration information that is held in files deployed with the application, located within the application folders. In some cases it is possible to edit these files to change the behavior of the application after it has been deployed. However, in many cases, changes to the configuration require the application to be redeployed, resulting in unacceptable downtime and additional administrative overhead. ...
Store the configuration information in external storage, and provide an interface that can be used to quickly and efficiently read and update configuration settings. The type of external store depends on the hosting and runtime environment of the application. In a cloud-hosted scenario it is typically a cloud-based storage service, but could be a hosted database or other system.
The backing store chosen for configuration information should be fronted by a suitable interface that provides consistent and easy to use access in a controlled way that enables reuse. Ideally, it should expose the information in a correctly typed and structured format. The implementation may also need to authorize users’ access in order to protect configuration data, and be flexible enough to allow multiple versions of the configuration (such as development, staging, or production, and multiple release versions of each one) to be stored."

"Microsoft SharePoint is a Web application platform developed by Microsoft. First launched in 2001, SharePoint has historically been associated with intranet, content management and document management, but recent versions have significantly broader capabilities.
SharePoint comprises a multipurpose set of Web technologies backed by a common technical infrastructure. By default, SharePoint has a Microsoft Office-like interface, and it is closely integrated with the Office suite. The web tools are designed to be usable by non-technical users. SharePoint can be used to provide intranet portals, document & file management, collaboration, social networks, extranets, websites, enterprise search, and business intelligence. It also has system integration, process integration, and workflow automation capabilities.
Enterprise application software (e.g. ERP or CRM packages) often provide some SharePoint integration capability, and SharePoint also incorporates a complete development stack based on web technologies and standards-based APIs. As an application platform, SharePoint provides central management, governance, and security controls for implementation of these requirements. The SharePoint platform integrates directly into IIS - enabling bulk management, scaling, and provisioning of servers, as is often required by large organizations or cloud hosting providers."
