8. @IamStan Serverless Design Patterns.. The Book!
9. @IamStan Primitive Pattern: Periodical (Cron Job) Primitive Pattern: Messaging API Pattern: Wrapper/Proxy API Pattern: Facade API Pattern: Async Orchestration: One way chain Orchestration: Two way chain Orchestration: Fan out Orchestration: Fan in Pipes & Filters: Workflow and Long Running Pipes & Filters: Streams Traditional: Command Traditional: Singleton Serverless Design Patterns.. The Book!

11. @IamStan Learning to Serverless Journey Deployed something into production Oh sh*t I need to maintain this thing Now I’m deploying servers to manage my serverless application I can never imagine doing it any other way Serverless is Lyf
12. @IamStan How not to serverless!
13. @IamStan The FaaSaaS Pattern (Function as a Service as a Server)

17. @IamStan FaaSaaS - GraphQL Edition > 40,000,000 visits per month ~ 5,000,000 visits per month

19. @IamStan FaaSaaS - Apex Up https://github.com/apex/up TJ Holowaychuk Apex Framework Express Mocha Koa 545 packages on NPM
20. @IamStan FaaSaaS - Apex Up Makes your function act like a VPS Up CLI for easy deployment Up Golang Proxy inside function JSON -> HTML
21. @IamStan FaaSaaS - Apex Up Runtimes: - Python - Golang - Node.js - Crystal - Static sites
22. @IamStan FaaSaaS - Apex Up Up CLI abstracts away - Lambda - API Gateway - Route 53 - CloudTrail - CloudFront - ACM

25. @IamStan FaaSaaS - Zappa https://github.com/Miserlou/Zappa Rich Jones Founder gun.io NoDB S3SQLite Gone in 60 Seconds (Intrusion and Exfiltration in Serverless Architectures)
26. @IamStan FaaSaaS - Zappa Python framework (supports 2.7 & 3.6) Works with any works with any WSGI*- compatible framework Includes Django, Flask, Pyramid, Bottle *WSGI = Web Server Gateway Interface
27. @IamStan FaaSaaS - Zappa -VTL to map body, headers, method, params and query strings into JSON, and then turning that into valid WSGI -Attaching response codes to response bodies, Base64 encoding, using that as a regex to route the response code, decoding in VTL, then mapping the response body -Packing and Base58 encoding multiple cookies into a single cookie -Turning cookie-setting 301/302 responses into 200 responses with HTML redirects
28. @IamStan FaaSaaS - Zappa Allows you to run your Python app in Lambda without any changes Allows you to run deploy decoupled Serverless Apps Broad support for AWS services (x-Ray, Cognito, SNS, etc) Up to date with AWS feature set (ie Dead Letter Queues)
29. @IamStan The wrens are mostly small, brownish passerine birds in the mainly New World family Troglodytidae. ... Most wrens are small and rather inconspicuous, except for their loud and often complex songs. - Wikipedia

31. @IamStan I’m not too sure what to call it - PyWren
32. I’m not too sure what to call it - PyWren @IamStan Streams your user code from S3 and hot loads it into Lambda Uses the Anaconda Python Runtime Can scale to your Lambda account concurrency limit Alternatively can use a single EC2 server
33. @IamStan Thank you!
34. @IamStan There is more than one way to Serverless!!
