What is FaaS?

Running back-end code without managing your own servers or your own application

DEMO TIME!

When and why should you use Azure Functions?

• Need to Reduce Cost
• Inconsistent AND Occasional traffic
• New Developers/Learning Programming
• Internal Tools and Automation
• When IFTTT Fails

Reduce Costs

• Reduce Operational Costs
  • No Server Maintenance (outsourced)
  • No Application Overhead (outsourced)
  • Easier DevOps deployment
• Inconsistent traffic
• Infrequent requests
• Code optimization directly affects cost! (Fun!)
• No meetings about:
  • Enough memory? Enough Throughput?

The Tradeoffs/Downsides

• Logic Repetition
• Local Dev/Test is harder for bigger apps
• Cognative overhead and complexity
• Sometimes there's no cost savings over PaaS

Conclusion and Thanks!
