What makes serverless, event driven computing so
attractive?

Serverless can handle many cloud native app 12 Factors
1. CodebaseOne codebase tracked in revision control, many deploys
2. DependenciesExplicitly declare and isolate dependencies
3. ConfigurationStore config in the environment
4. Backing servicesTreat backing services as attached resources
5. Build, release, runStrictly separate build and run stages
6. ProcessesExecute the app as one or more stateless processes

Application
Problem: Programming and pricing models aren’t efficient
• Continuous polling needed in the absence of an event driven programming model
• Charged for resources, even when idle
• Worries persist about capacity management
