This document discusses caching services available on Windows Azure, including content delivery networks (CDNs) and caching. It describes how CDNs deliver content closer to end users, and caching stores frequently accessed data closer to Azure applications. Caching on Azure can be done through dedicated roles, co-location with applications, or shared caching services. The document outlines characteristics of CDNs like dedicated endpoints and worldwide datacenters. It also provides examples of caching configuration and workflows in Visual Studio and code samples for putting and getting items from the cache.

- 2. Caching services 2 CDN • Delivering a “heavy” content closer to end user Caching • Storing frequently accessed data closer to Windows Azure application: • Dedicated role • Co-location Shared caching • Dedicated multi-tenant service

- 4. Main characteristics 4 Dedicated endpoint • To work through the CDN you need to change storage services endpoint to CDN endpoint. Dedicated billing • CDN usage is billable separately from storage services billing World wide • More than 20 CDN datacenters around the world
- 5. Content Delivery Network CDN datacenters 5
- 6. Caching 6 Two configuration models: • Dedicated role • Co-location “Pay-as-you-go” only for compute resources Several logical named caches Ability to store session state and page output objects
