Departmental Application Migration to Azure – Part 1Solution ·
I’m currently looking at how Windows Azure could help my company. As a proof-of-concept, I’m going to migrate a departmental application to Windows Azure.
The application is quite simple, but the migration should contain its share of challenges. The current application is a simple MS Access front-end exposing a few forms. The data source is an SQL Server Database. It uses the identity of the user to write some data (e.g. user name) to SQL tables.
My a priori approach, or target solution architecture is:
- Use SQL Azure to host the database
- Use two SQL account, a read-only one for reporting from on-premise, one writeable in-use by the application only
- Use ADFS v2.0 to extend the corporate identity to the cloud
- I’ll try to install it on a local VM for demo
- Build a web application as one web role accessing the DB directly
I suspect the biggest challenge will come from ADFS, partly because I’m no AD-expert, partly because it’s new and there is little documentation around.
I’ll write blogs as I go along. I’m doing many other things at the same time and that migration is actually low-priority, so it will most likely take a few weeks. I’ll link the blogs together.
