1. Going serverless –
 NoOps is the best ops Steven Ringo AWS Meetup Sydney 2 March 2016
2. No Servers? Wut?
5. Bare Metal Deploy in months Lives for far too long! Containers Deploy in seconds Lives for hours AWS Lambda Deploy instantly Lives for seconds Virtualisation Deploy in minutes Lives for weeks
6. Gazillions of baby Lambdas
8. AWS
 Lambda A compute service where you can upload your code and it runs the it on your behalf using AWS infrastructure.
9. AWS
 Lambda Code function that executes when triggered by an event. Handler
10. AWS
 Lambda Things that happen in AWS services: Event source API Gateway S3 SES SNS CloudWatch
 (logs, events & scheduled actions) CloudFormation DynamoDB Kinesis Cognito
11. AWS
 Lambda Trigger from custom REST API and endpoint using Amazon API Gateway HTTPS only API Gateway event source
12. AWS
 Lambda RequestResponse type Assumes response will be sent Asynchronous type for other applications Synchronous invocation
 for API Gateway
13. AWS
 Lambda Supported: • Javascript (NodeJS) / Python / JVM Unsupported: • Ruby / Go / Haskell • (Actually anything) Languages
14. AWS
 Lambda Console for simple implementations with no external dependencies. or Zip file with your code and dependencies. Upload directly or use S3 Deployment package
15. AWS
 Lambda Only local state, and is limited to the current Lambda execution Stateless
16. Amazon API Gateway A scalable, fully-managed service to publish, maintain, monitor, and secure APIs.
17. Amazon API Gateway Each resource within a REST API can support one or more of the standard HTTP methods Define verbs supported for each resource (GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS) and their implementations RESTful
18. Amazon API Gateway Built in staging multiple stages (e.g. dev, test, deploy) Built-in versioning multiple versions simultaneously Staging & versioning
19. Amazon API Gateway Works with Lambda or your own publicly accessible endpoints Lambda- or custom-backed
20. Amazon API Gateway Custom authorisers, e.g. JWT, OAuth Cognito integration Authorisation & Authentication
21. Amazon API Gateway Allows resources on a web page to be requested from another domain outside the domain from which the resource originated, e.g. calls to API Gateway endpoints CORS support
22. Amazon API Gateway Android, iOS, or JavaScript boilerplate SDK code generation
23. GET https://romanapi.com/v1/numeral/MCMLXIX { "result": 1969, "arabic": 1969, "roman": "MCMLXIX", "success": true, "original": "MCMLXIX" }
24. Amazon
 S3 Host static websites Massively redundant & scalable Great for assets
 (css/images/javascripts) Custom domain names TLS supported
25. Amazon CloudFront A global content delivery network (CDN) service
26. Amazon CloudFront Improve performance of your web-facing assets
27. Amazon CloudFront Additional layer of security, esp when coupled with WAF
28. AWS WAF Web Application Firewall A web application firewall that helps protect your web applications from common web exploits
29. Fully managed, scalable, fast NoSQL database Amazon DynamoDB
32. middlemanapp.com
33. jekyllrb.com
36. apex.run
37. Serverless should be considered as part of your cloud strategy
38. Serverless is just another tool in your cloud toolset
