Microservices in action: How to actually build

themAndrzej Jarzyna, the API guy from 3scale ;)

APIs on Lambda and API Gateway

•Lambda Functions - microservices written in JS/Python/Java hosted on Amazon Cloud

•API Gateway - a ‘front door’ to access your APIs endpoints

Features of Lambda• functions ran on a ‘serverless’ cloud

• have access to other AWS services, http endpoints and in-app events

• runs only when triggered (stateless)

• pay only when called
