Incubation: Looking glass -Progression to Windows Azure

Patrice PellandPrincipal Dev Manager, Microsoft Corp.

Social Monitoring – Incubation• Social Monitoring incubation project codename Looking Glass

• Silverlight 4 application, Windows Phone 7 application and iPhone/iPad application – Code Reuse.

• Progression of the back end from

• Windows Server 2008 R2 with WCF Services, SQL 2008 R2

• Windows Azure (Web Roles and Worker Roles), SQL Azure

• Windows Azure (Web Roles and Worker Roles), SQL Azure, Azure Storage (Table Store, Blob storage)

WP 7 Application

Code Re-Use Explorations• Since Silverlight is X-Platform and X-Browsers we

were able to have our project run (with the SL download) across browsers and cross OS.

• Worked on PCs, Mac OSx and Linux (via Moonlight)• Worked on iPhone/iPad via Monotouch• Kept 85% of the code to have the code run on

iPhone/iPad and Linux.

Back End Progression – Phase 1

Why it did not scale?• Regular Social APIs with limitations on # of

calls• Generic Data Acquisition Service• No partitioning

Back-End Progression – Phase 2

Scalability issues still there for the back end…

• Crawling became more scalable with worker queues

• Still not the complete data corpus and not fast enough to query – Full text index and tag indexes

Conclusion…

• Moving to Azure was cost effective• Reliable, scalable and available• Changing the approach to using indexers gave

us a more interesting and complex query and filtering capability.
