A Crash Course on Serverless Applications in Python

on YouTube ↗25m

" summary

Overview of how to build and deploy a working serverless Python app: uses AWS Lambda, Amazon API Gateway and S3 events, packaged via AWS CLI or Chalice which generates IAM roles and deploys dependencies like boto3 and Pillow into Linux wheels. Example is a thumbnail resizer (about 20 lines of code) that downloads with parallel multipart download, resizes, uploads via multipart upload and runs successfully; tip: create clients at module level to avoid repeated cold-start work. Runtime shown: Python 3.6, billed per 100ms.
