This document discusses serverless computing on AWS. It provides an overview of AWS serverless services like Lambda, API Gateway, S3, DynamoDB, and others. It discusses how these services work and their advantages like automatic scaling, high availability, and pay-per-use pricing. It then presents three use cases where a company called SourceFuse leveraged various AWS serverless technologies to build applications for video ad generation, route mapping, and transport request processing.

Serverless Computing, AWS Way by SourceFuse Technologies
- 1. Serverless Computing AWS Way By: Manpreet Singh, CTO
- 2. WHO WE ARE We are a team of over 150 technologists helping companies increase revenues and decrease expenses through technology and product development.
- 3.

- 4. Serverless Computing Build and run applications without thinking about servers No Server Management Flexible Scaling High Availability No idle capacity
- 6. AWS Serverless Platform Compute - Lambda API Proxy - API Gateway Object Storage - S3 Database - DynamoDB IPC - SNS, SQS State Machine - Step Functions Analytics - Kinesis
- 7. AWS Serverless Platform The Magic Happens at the Intersection of Functions, Events and Data. (Pretty much everything else is glue or UI) -Werner Vogels
- 8. AWS Lambda
- 9. AWS Compute Offerings Service EC2 ECS Lambda Unit of Scale Virtual Machine Application Function Abstraction at Hardware Operating System Runtime
- 10. AWS Lambda Run code without thinking about servers. Pay for only the compute time you consume - subsecond metering Built-in scaling, monitoring and fault- tolerance Choice of runtime - node.js, java, c#, python
- 11. In node.js event??? Lambda - Hello World
- 12. Lambda - Event Sources Over a dozen event sources
- 13. Lambda - Event Sources … and others like DynamoDB, SNS, SES, API gateway, CodeCommit, Cloudwatch events, Cloudformation, etc
- 14. Lambda - Configuration ◎Runtime (node.js, java, c# and python) ◎Environment variables ◎Memory allocated (128MB to 1536 MB) ◎Timeout (upto 5 minutes) ◎Handler function name ◎Role assigned
- 15. Lambda - Deployment ◎Setup using Cloudformation - SAM ◎CI (can be AWS codebuild, jenkins, etc) i. Package code with dependencies as a zip file ii. Put on S3 iii. And create a new version of function
- 16. Lambda - Versioning ◎Version no. for each deployment ◎Alias for dev, stage, prod, etc (soft link)
- 17. Lambda - ImPoints ◎Concurrent executions ◎Synchronous vs asynchronous calls ◎Cloudwatch monitoring ◎Retries on error ◎Container reuse ◎Can be made part of VPC
- 18. AWS API Gateway
- 19. API Gateway - Why? Exposing REST API had been challenging: ◎Will have to manage and scale web servers ◎Authorization is tricky over longer run ◎Tough to manage multiple versions of APIs ◎Tedious to monitor access by third party
- 20. API Gateway - How? Solves all these problems by - ◎Having multiple versions and stages of API ◎Inbuilt support for security, monitoring and throttling ◎Integration with swagger for maintainable and documented APIs ◎Request/Response transformation ◎Easily connects to backend like Lambda/EC2 ◎API Mocking
- 21. API Gateway - Flow
- 22. API Gateway - Versions
- 24. AWS Web Reference Architecture
- 25. AWS Mobile Reference Architecture
- 27. UC1 - adpoint.video ◎Engine to generate video ads ◎Video template is configurable ◎Video made using multiple Lambda functions using ffmpeg for video manipulation ◎Speech to text to sync text with audio
- 28. UC1 - adpoint.video Configuration Sample Output - Dollar Tree
- 29. UC2 - RelayTransport Lambda function which generates route image using google maps and latitude-longitude array
- 30. UC3 - RelayTransport Accepting transport requests over email Incoming email Send SNS Triggers Lambda AWS SES AWS SNS Parses Email Creates job for app to process AWS SQS
