1. with @DavidWells Microservices Building
2. I'm @DavidWells Software Developer @
4. AWS Lambda
6. How did we get here 1. Build and maintain your own machines 2. Buy space in someone else's server farm 3. Run virtual machines in the cloud 4. Run containers in the cloud 5. Serverless Compute
7. Serverless?
8. WTF!!!!! Serverless?
10. Serverless Auto-scaling focus on your core application logic not infrastructure Event Driven Architectures Never pay for idle Code runs as stateless functions Leverage third party services
13. after free tier $0.20 per 1 million requests ($0.0000002 per request) First 1 million requests (400,000 GB-seconds) free per month
17. • Nordstrom • Coca-Cola • Autodesk • Angie’s List • Vevo • Booz Allen Hamilton • NY Life Insurance • Australian Government • LendingTree • Amazon • Vice • Accenture • And more Enterprise Users Serverless State of the union re:Invent 2016 youtube.com/watch?v=AcGv3qUrRC4

21. You can manually do this in UI...
22. Your code + + = infinitely scalable, pay-per-execution microservices Framework (CLI)
23. Project Structure code: handler.js config: serverless.yml Framework
24. serverless.yml config file
25. Where to run serverless.yml config file When to run What to run
26. Where to run What to run When to run serverless.yml config file
27. named export saveUser function is referenced in serverless.yml handler.js file
30. Your code runs in response to events - a POST request is sent to /createUser - a new item is added to the database - a scheduled cron triggers - a new image is added to an s3 bucket - an infrastructure event matching a rule is found - a SAAS webhook is fired - a link in an email is clicked - ... etc
31. use cases
32. • DevOps/Infrastructure Automation • Auditing resources for security • Bots (Chat/Voice) • Alexa skills • IoT events • Infrastructure events • S3 - new files, updated files etc • DynamoDB - new items in DB • ... • Web + Mobile backend APIs • Form processing • Image processing • Web scraping / testing • Running binaries • Serving HTML / dynamic binaries • Webhook listeners • Cron jobs github.com/serverless/examples Use Cases
