13. Using the Windows Azure
Platform: Scenarios

14. Applying Azure (1)
Some characteristics of Azure-appropriate applications
 Apps that need massive scale
– Example: A Web 2.0 application
 Apps that need high reliability
– Example: A Software as a Service (SaaS) application
 Apps with variable load
– Example: An on-line ticketing application
 Apps with a short or unpredictable lifetime
– Example: An app created for a marketing campaign
 Apps that do parallel processing
– Example: A financial modeling application

15. Applying Azure (2)
Some characteristics of Azure-appropriate applications
 Apps that must fail fast or scale fast
– Example: Start-ups
 Apps that don’t fit well in an organization’s data
center
– Example: A firm with no data center
– Example: A joint venture
– Example: A business unit that wishes to avoid its IT
department
 Apps that can benefit from external storage
– Example: An application that archives data
