Serverless Applications using AWS Lambda and SAM

Serverless platforms significantly reduce the cost of running high-performance web sites and API services in the cloud, but with a major impact on architecture, these services also require teams to re-think how to approach sessions, storage, authorization and testing.

This workshop is based on real-world experience of moving a large collaboration platform from Heroku to AWS Lambda, leading to a huge improvement in scalability and performance, and a significant decrease in cost.

Learn how to

• Use AWS Lambda and API Gateway
• Perform file conversion, image serving, connecting to third-party APIs and managing sessions with serverless architectures
• Design scalable, high-performance web sites with single-page apps backed by cloud APIs
• Get the most out of AWS integrations (AWS Cognito and AWS IoT Gateway)
• Identify how serverless architecture impacts testing, monitoring and deployments
• Run A/B tests easily and operate multiple versions of your system cheaply by learning best practice
• Start converting monolithic applications to cloud functions
• Use Amazon Serverless Application Model (SAM) and Claudia.js to deploy Lambda functions

Topics

Day 1: Getting started with Lambda and performing basic tasks

• Introduction to AWS Lambda and API Gateway
• Logging, monitoring and analytics in a serverless world
• Connecting Lambda functions to storage (S3)
• Invoking Lambda functions from Web APIs
• Securing Lambda functions

Day 2: Architecting serverless applications

• Designing applications for share-nothing architectures
• How to achieve user sessions and still work at scale
• Key things to consider when talking to third-party APIs
• Authentication and authorization with serverless applications
• How to design testable Lambda functions
• How to set up your workflow for teamwork and versioning

Audience

This course is perfect if you are a software developer or architect migrating from on-premise applications to the cloud or also if you are investigating the migration from self-managed applications (virtual machines in the cloud) or Platform-as-a-Service (Heroku, Google App Engine) applications to AWS Lambda and cloud functions.

Prerequisites

A working knowledge of JavaScript is encouraged as coding examples will be in JavaScript/Node.js to keep things simple and make it easy for everyone to follow regardless of their primary platform. You should be comfortable writing simple functions and flows.

Computer setup

Attendees will need to bring your own laptop with the following installed:

• Node.js 6 or 8
• NPM 3 or higher
• AWS Command line tools
• a code editor (any will do, but something with JavaScript support will speed things up)

Please read the following setup instructions:
