Serverless Compute❖ Next step in the evolution of Cloud Computing❖ Capability to run your code or a function in the

cloud without the need to manage any server in the cloud.

❖ Big Players ❖ Amazon - AWS Lambda❖ Google - Google Cloud Function❖ Microsoft - Azure Functions

Benefits of Serverless Compute❖ No servers to administer

❖ No Need Maintain and Manage Server - applying updates

❖ Pay for only code execution❖ No charge when the code is not running

❖ Automatic Scaling

AWS Lamba❖ Function in the Cloud❖ Automatic Scaling❖ Pay as you go

❖ Pricing – 1M requests for free and then $0.20/1m requests.❖ Supported languages – Java, Python, and JavaScript❖ Deployment – direct zip uploads lambda or from S3.❖ Event Driven – Different source can trigger your function.❖ RESTful invocation capability using AWS API Gateway.❖ Logs management on CloudWatch.❖ Maximum execution time – 5 minutes.

Invoking AWS Lambda❖ AWS API Gateway❖ S3 - File is added/uploaded / deleted❖ SNS❖ Kinesis Stream❖ Custom Scheduler❖ Amazon Echo, IOT Actions, Cognito, SWF …
