This document provides an overview of serverless services on AWS. It describes 8 AWS services including Lambda, S3, DynamoDB, API Gateway, SNS, IoT, SES, and SQS. It provides examples of how to build a serverless blog application using these services, with the application assets stored in S3, API Gateway invoking Lambda functions, and blog data stored in DynamoDB. The document also discusses the Serverless Framework for developing and deploying AWS Lambda solutions and provides pricing models for various serverless services.

- 4. AWS SERVERLESS WORKSHOP BLOG APPLICATION Example 2 2. Web app communicates with API Gateway for blog content 1. Application static assets (HTML, CSS, JS) served from S3 bucket. 5. Blog data managed in DynamoDB database http://hackathon-blog.serverless.fi 3. API Gateway invokes Lambda for incoming requests 4. Lambda reads / writes blog data from DynamoDB See workshop at http://hackathon.serverless.fi/workshop.pdf
- 5. SIMPLE STORAGE SERVICE (S3) § (Unlimited) file storage service § Application internal files § Static web content (e.g. application HTML / CSS / JS / image assets) § Can be complemented with Cloudfront CDN to optimize costs and performance Serverless Storage my-s3-bucket.company.com PRICING: Storage volume + amount of requests
- 6. AWS LAMBDA § Compute service for running code (functions) in AWS § Event driven (API Gateway, SNS, SES, S3, DynamoDB, Schedule, …) § Provision memory & max time required by single function run § Additional ”instances” spawned automatically Serverless Compute myFunction PRICING: Utilized gigabyteseconds (rounded to 100ms)
- 7. API GATEWAY § AWS Service to implement REST (and other) APIs § Security via API Keys, customer authorizers (Lambda) § Connect to e.g. Lambda to publish your functions as REST interfaces § Input / Output mapping (e.g. URL parameters -> JSON) § No need for provisioning Serverless API Management PRICING: # of requests + data transfer + cache size INPUT MAPPING OUTPUT MAPPING AUTHORI- ZATION JSON JSON HTTPS
- 8. DYNAMODB § noSQL database provided by AWS § noSQL: scalable non-relational database with focus on speed § Work with tables and indices, no server instances to manage § Need to provision read / write capacity per table / index Serverless Database PRICING: Provisioned read / write capacity and storage (over 25Gb)

- 10. OTHER AWS MANAGED SERVICES & EXAMPLES 10
- 11. SIMPLE NOTIFICATION SERVICE (SNS) § Push notification service § Delivery not guaranteed § nly targeted for mobile notifications § Can also be used for triggering e.g. Lambda functions, mobile, email notifications Serverless push notifications PRICING: Amount of messages 1 SUBSCRIBE PUBLISH
- 12. SIMPLE QUEUE SERVICE (SQS) § Message queue service (pull) § Delivery Guaranteed (order not guaranteed) § Prevent messages being handled by multiple workers § Can be handled e.g. by Lambda using a scheduled function Serverless queue PRICING: Amount of messages (SCHEDULED) PULL PUBLISH
- 13. AWS IOT § Device registry + API for communicating with devices + automated actions (Rules) § Authentication of devices § Devices can send current state and retrieve desired state over MQTT, Websocket § Can perform actions based on rules (e.g. Temperature reading from a specific sensor is out of bounds) Integrate with devices PRICING: Amount of messages
- 15. CLOUD NATIVE APPLICATION ARCHITECTURE À LA SC5 Reference Architecture AWS IoT Amazon S3 Amazon DynamoDB Amazon RDS Amazon SNS Amazon API Gateway AWS Lambda E.g.App assets (HTML5) App Notifications App Data (REST) Device data (MQTT) Compute Database Serverless Development Framework
- 17. SERVERLESS FRAMEWORK § Node.js based framework for development and deployment of AWS Lambda-based solutions § Extendible via plugins § Initially JAWS but rebranded to Serverless in Dec 2015 > npm install –g serverless > sls project create > sls resources deploy > sls function create > sls function deploy > sls endpoint deploy > …
