11. Everything
12. Everything*
13. • DevOps/Infrastructure Automation • Auditing resources for security • Infrastructure events • S3 - new files, updated files etc • DynamoDB - new items in DB • Alexa skills • IoT events • Bots (Chat/Voice) • Web + Mobile backend APIs • Form processing • Image processing • Web scraping / testing • Running binaries • Serving HTML / dynamic binaries • Webhook listeners • Cron jobs
14. What can't serverless do? • Processes running longer than 5 minutes
15. Some Examples

18. • Static Site built with phenomic.io served up from a CDN • React SPA experience on load • Functions for: • Form processing • 404 tracking/Analytics • Protected API calls for authed users • Serving up dynamic routes HTML AKA will scale without living a finger
19. Protect API Example auth0-serverless-protected-routes-demo.surge.sh

21. Finding More Use Cases and Examples
22. • Nordstrom • Coca-Cola • Autodesk • Angie’s List • Vevo • Booz Allen Hamilton • NY Life Insurance • Australian Government • LendingTree • Amazon • Vice • Accenture • And more Enterprise Users Nordstrom - is a framework contributor and user. They have 200 Lambda functions in production and do 100 million invocations daily. Use-Cases: Web back-ends, DevOps automation & streaming data processing. Coca Cola - is a framework contributor and user. Has a mission to do all of its 200+ marketing projects a year as “serverless” projects with the Framework. Use-Cases: Web and mobile back-ends. “The Serverless Framework is a core component of The Coca-Cola Company's initiative to reduce IT operational costs and deploy services faster.” - Patrick Brandt, Solutions Architect, Coca-Cola

24. Enterprise Examples • Accenture (and other agencies) using it to build large backends that can be handed over to the client ready-to-scale • Coca Cola using it to build dozens of marketing sites that handle very spiky traffic • Survata is using it to process hundreds of millions of events and drop cookies • Nordstrom: serverless with artillery and you get serverless-artillery for instant, cheap, and easy performance testing at scale. • Netflix is using for parrallel processing for encoding media files and for security/auditing • A cloud guru: serverless driven training site.
