The Windows Azure Platform enables developers to build dynamically scalable web applications easily. Come and learn how services like the Content Delivery Network (CDN) and Windows Azure AppFabric Caching can help you build high-performance web applications in Windows Azure. In this session we’ll share some tips & tricks to improve performance when using web & worker roles in Azure, and to optimize your overall application for maximum performance.

Non-public blob
(e.g. paid or ad-
funded content)
1. “I am Bob & I want X”
2. Service prepares a
Shared Access Signature
(SAS) to X using the
securely stored storage
account key
3. Service returns SAS (signed HTTPS URL)
4. Bob uses SAS to access X directly
from Blob Storage for reduced
latency & compute load
