Presented at ServerlessConf NYC 2016. A Cloud Guru is a completely serverless online learning platform that connects 50,000+ users in real-time, using AWS Lambda, Firebase and a huge array of 3rd party cloud services. We’ll tell the story of building a completely serverless company, and how this approach has literally fueled our business model, and enabled us to disrupt the training industry. We’ll explain the 5 principles you should following when adopting serverless architectures, and walk through real-world examples of each from our platform. Expect to hear about AWS Lambda, Firebase, Auth0, CloudSearch, Elastic Transcoder, S3, CloudFront CDN and lots of JavaScript!

10. Principles of Serverless Architecture
Illustrated with A
Cloud Guru Examples
Use a compute service to execute code on demand
Write single-purpose stateless functions
Design push-based, event-driven pipelines
Create thicker, more powerful front ends
Embrace third party services

11. 1. Use a compute service to execute
code on demand (aka don’t run a
server).

12. API Gateway
Lambda Function
Simple Queue ServiceKinesis
Client
S3 Bucket (Storage)
Compute as back end

13. Simple Notification Services
S3 Bucket (Storage)
Relational Database Service
CloudSearch
S3 Bucket (Storage)
Simple Email Service
Compute as glue

14. 14
Lambda is to compute, what S3 is to storage.

15. 2. Write single-purpose stateless funcGons
