AzureScope : This is a great resource about Windows Azure,I really recommend you to invest some time and read the content it contains.You will find really valuable information about:
- Benchmark test cases and throughput reports
- Best practices on developing on Windows Azure.
- Code Samples.
Hope that you find it useful.
Additionally I would also recommend to have a look to Azure Research Engagement, it contains interesting information about how Azure is being applied in research projects.
