• Social-Mobile era increasing

demand variance

• Application lifespans compressed

• Support massive dynamic scaling

• Scale efficiently and rapidly

• No outages due to capacity

limitations

Problem

Application Scaling

• Scale-out and scale-in on demand

using Azure compute roles

• Decompose application for discrete

scaling of application components

• Utilize performance monitoring and

management APIs to auto scale

deployments

• Throttle Tenants
