3. 3 09.06.17 What is AWS Lambda Serverless compute service Introduced by Amazon in November 2014
4. 4 09.06.17 What means serverless Serverless = no servers ?
5. 5 09.06.17 What means serverless NO, there are servers But someone else is responsible Cloud Provider
6. 6 09.06.17 Goal behind serverless Primarily focus on code Not infrastructure Capacity, Scaling, Monitoring, Logging, Security Patching ...
7. 7 09.06.17 Replace serverless with ... FaaS Function as a service CoD Code on demand
8. 8 09.06.17 Flow Changes in data state Request to endpoints Changes in resource state Event source Function Services (anything) Change/Add data state Trigger AWS resource Call HTTP endpoint Your Code
9. 9 09.06.17 Events Event Sources Event sources that trigger AWS Lambda • Amazon S3 • Amazon DynamoDb • Amazon Kinesis • Amazon API Gateway (REST API) • On Demand via SDK • ... approx. 16-17 services
10. 10 09.06.17 Function Write single-purpose stateless functions single responsibility principle
11. 11 09.06.17 Function Runtimes NodeJS 4.3 & 6.10 Java 8 Python 2.7 C#
12. 12 09.06.17 Function ZIP Package handler-xyz.js node_modules/* Terraform example resource "aws_lambda_function" "lambda_nodejs_example" { filename = “directory/example-nodejs-lambda.zip" function_name = "example_nodejs_lambda" handler = ”handler-xyz.handler" runtime = "nodejs6.10" }
13. 13 09.06.17 Use Case 1 2 3 4 Store image in S3 Lambda Event Trigger Create thumbnail Store thumbnail in S3
14. 14 09.06.17 Use Case E-Mail DeskPro Middleware TargetProcess API Gateway Create bug ticket Close ticket Create ticket Webhook Event source Lambda DeskPro -> TargetProcess (fully automated)
15. 15 09.06.17 Limits Maximum execution duration per request => 300 seconds Alternative S3 Storage Lambda function deployment package size (.zip/.jar file) => 50 MB 100 concurrent executions 1.000 invokes per second Increases available via AWS customer service
16. 16 09.06.17 Costs 1 million requests and 400,000 GB-second of compute time every month, every customer for free $0.20 per 1 million requests ($0.0000002 per request) Never pay for idle
