Allow applications to scale user and compute processing independently. Two role types: Web Role & Worker Role Windows Azure applications are built with web roles, worker roles, or a combination of both deployed to a number of instances. Each instance runs on its own VM (virtual machine), replicated as needed Cloud Compute Services (example Windows Azure) Windows Azure storage is an application managed by the Fabric Controller Windows Azure applications can use native storage, MySQL within a VM, or SQL Azure Application state is kept in storage services, so worker roles can replicate as needed Blobs can be stored in global Windows Azure Content Delivery Network (CDN) Storage Services (example Windows Azure) GOAL: Scalable, durable utility-based storage Service Model Simple topology view Initial Size 2 SharePoint App Servers 1 SQL Server Growth Unit A Capacity Driver: # of users +1 SharePoint Application Server Growth Unit B Capacity driver: content db size +1 SQL Server Max Growth 4 SharePoint App Servers 2 SQL Server Petes SharePoint order (representing max growth): - 50,000 users - 20,000 team sites - 150MB/site - Responses per second: 100 Farm configurationRPS 2 by 199 Farm configurationRPS 4 by 2120 Farm configurationRPS 3 by 1115 Monitoring counters in the operational configuration and monitoring environment (SC OM 2007) trigger growth (or shrink) provisioning once the specific capacity driver hits 80% of specified value: - Growth based upon RPS (growth type A): initial size 99 RPS; counter is set to 80 RPS - Growth based upon content db size (growth type B): initial size 0.8 TB; counter is set to 0.7 TB Sign up for TechEd 2011 and save $500 starting June 8 June 31 stYou can also register at the North America 2011 kiosk located at registration Join us in Atlanta next year
