The document is a presentation on serverless architectures given by Lê Thanh Sang, a senior developer at GO1. It begins with an introduction of the speaker and overview of GO1. The bulk of the presentation defines what serverless computing is, highlights the benefits, and provides examples of serverless products and architectures using various AWS services. It concludes with a demo of a serverless note taking application built on S3, API Gateway, Lambda, and DynamoDB and a Q&A section.

- 5. Benefits of Serverless? Provisioning and Utilization Operations and Management Scaling Availability and Fault Tolerance Which leads to…. Low Cost Simple Low Latency Scalable Reliable
- 6. Platform of Serverless Products Storage DatabaseCompute Messaging and QueuesGateways User Management Internet of Things Machine LearningStreaming Analytics
- 8. ETL (Extract, Transform, Load)
- 9. IoT Backends
- 10. Web Application Serverless Architecture
- 11. Anatomy of a Web Application
- 12. What makes up a web application? • Let’s break it down…
- 14. Where did all the servers go?
- 15. Static Website Hosting on S3 - refresher Specify an index document (i.e. index.html) Specify an error document Objects publicly readable Supports redirects All Requests Conditional bucket with objects
- 16. API Gateway - refresher Create Configure Publish Maintain Monitor Secure
- 17. API Gateway – Stage Variables Key/Value pairs used for configuration Used for different stages of API Specify a Lambda function name Pass to backend
- 18. Lambda Serverless, event-driven compute Code is: NodeJS, Python, JVM based Specify memory allocated Determine what invokes the functions API Gateway, S3, DynamoDB, Kinesis, SNS, SES, Cognito, Cloudwatch Logs, Cloudwatch Events, CloudFormation, Config, Scheduled Events
- 19. Lambda – Versioning and Aliases • Versioning ARN for each one (immutable) Versions of functions for Dev, Staging, Prod • Aliases Point to a version Have an ARN also Event sources point to Alias ARNs
- 20. Lambda – Dynamic Configuration • One option: Pull Configs from DDB Write values to global vars Code uses global vars Lambda Function Amazon DynamoDB
- 21. DynamoDB - refresher NoSQL database Keys: Hash Key and (optional) Range Key Tips: Plan your keys Think about your queries
- 23. Demo App Architecture AWS Lambda Functions web browser Amazon S3 Dynamic Content StaticContent Amazon DynamoDB Amazon API Gateway 1
- 24. Architect to be Serverless • Fully Managed No provisioning Zero administration High availability • Developer Productivity Focus on the code that matters Innovate rapidly Reduce time to market • Continuous Scaling Automatically Scale up and scale down
