3. 3 02.06.17 What is AWS Lambda Alternatives • Azure Functions (Microsoft) • OpenWhisk (IBM) • Google Cloud Functions (beta) Serverless compute service that runs your code in response to events Introduced by Amazon in November 2014 First major provider
4. 4 02.06.17 What means serverless Serverless • No infrastructure to manage • Upload your code • Lambda handles Capacity, Scaling, Monitoring, Logging, Security patching ...
5. 5 02.06.17 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
6. 6 02.06.17 Workflow 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
7. 7 02.06.17 Function Function handler NodeJS 4.3 & 6.10 Java 8 Python 2.7 C# ZIP Package handler.js node_modules/*
8. 8 02.06.17 Use Case 1 2 3 4 Store image in S3 Lambda Event Trigger Create thumbnail Store thumbnail in S3
9. 9 02.06.17 Use Case E-Mail DeskPro Middleware TargetProcess API Gateway Create bug ticket Close ticket Create ticket Webhook Event source Lambda DeskPro -> TargetProcess (fully automated)
10. 10 02.06.17 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
11. 11 02.06.17 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
