I haven’t been blogging as much in the past few months, but I have a good excuse. I have been heads down over the last few months working with several clients on different, innovative projects that leverage the Windows Azure Platform. From media processing to federated authentication to scalable services and database, Slalom Consulting has been doing great work in the cloud.
Project Highlight: Cloud-based Tax Form Application
Slalom has engaged with an existing tax and accounting firm to build a web-based tax form application that leverages several features of the Windows Azure Platform. The application is an ASP.NET MVC3 application running in Windows Azure compute as a Web Role. Information collected by the application is stored in a SQL Azure relational database. Asynchronous operations, such as data imports and exports, are executed in Windows Azure Compute as Worker Roles, and those operations are triggered by messages stored in Windows Azure Queues. Furthermore, documents related to the tax collection process are securely stored as BLOBs in BLOB Storage.
The web application is configured against the Access Control Service to allow users to authenticate via 2 identity providers. Employees of the firm, who manage their tax clients, authenticate with their corporate credentials via Active Directory Federation Services. Clients themselves authenticate via custom client identities. The client identity store sits behind a custom STS (security token service), also an ASP.NET MVC3 application leveraging Windows Identity Foundation, and running in Windows Azure compute.
