(そのうち、日本語にしたいと思ってます ↓ )
Introduction
This sample demonstrates a real-world SaaS architecture and scenario using the Azure Services Platform to perform federation and multi-tenancy. Technologies used include the Access Control service (part of .NET Services) as well as SQL Data Services (part of SQL Services).

Overview
Azure IssueTracker demonstrates a real-world ISV scenario where you want to create and host a SaaS application for your consumers. This sample is being releasede in two versions: Standard and Enterprise. The Standard version allows ad-hoc users to use LiveID federation with the .NET Access Control Service and authorize other LiveID users. This allows small groups of users to quickly provision projects and issue tracking capabilities.
The Enterprise version of IssueTracker uses the same claims-based authorization capabilities as the standard version, but allows greater control by customers over claims and authorization decisions. Additionally, the Enterprise version offers more premium capabilities like onsite configuration and monitoring in true S+S fashion.
The IssueTracker service itself is a very simple service – providing basic issue management and workflow capabilities. Because the service and the website are claims-aware applications, it allows for some interesting scenarios. Using a single set of claims and authorization logic, both active clients and passive web clients can consume the IssueTracker service. This architecture gives us the best of software on premises with rich UI capabilities as well as the broad reach of web clients – without changing a single line of code to support it.

Coming Features
Enterprise Version of IssueTracker which includes:
Federation with any SAML 1.1 compliant identity provider
MMC management tools – allows your customers to manage your service just like on-premises.
Integration with monitoring – customers can integrate with popular monitoring packages and monitor the health of the service
