Serverless using AWS Lambda for Java Developers - Tutorial from Bharath Thippireddy (Udemy)

Section 4: Create a Serverless Project

31. Passing parameters

• Test with event in Lambda Console
  • Event: just "Art"
• Test locally
  • sam local invoke SimplestLambdaFunction -e events/event-string.txt

34.1 Maven Shade Plugin

• cd SimplestLambdaFunction
• mvn clean package -> will invoke shade plugin
• cd ..
• modify template.yaml to reference codeUri to JAR
• sam deploy (WITHOUT build)

34.2 Custom build process

1. Make sure make command is installed

• for Windows, I installed chocolatey package manager
• then choco install make
• reboot
• make -h -> ok

2. Create Makefile
3. Modify template.yaml to use makefile BuildMethod
4. Build

• sam build
• got uber-jar in .aws-sam/build/SimplestLambdaFunction/

5. Deploy

• sam deploy
• deployed zip with jar)))

6. Test

• error ->

{
  "errorMessage": "Class not found: net.shyshkin.study.aws.serverless.simplest.App",
  "errorType": "java.lang.ClassNotFoundException"
}

35. Test Locally

• sam local invoke SimplestLambdaFunction --event events/event.json
• docker image ls
  • public.ecr.aws/sam/emulation-java11 rapid-1.36.0-x86_64
  • pulled image and executed in it

52. Invoke Remotely From Command Line

1. Asynchronous invocation

• return void
• aws lambda invoke --invocation-type Event --function-name parameters-and-types-stac-ViewEnvironmentVariables-kgGuhdvUNXqN outputfile.txt

2. Synchronous invocation without payload

• aws lambda invoke --invocation-type RequestResponse --function-name parameters-and-types-stack-ViewContextFunction-ksJFkQHLn6nK outputfile.txt

3. Synchronous invocation with payload

• input number - inline
• aws lambda invoke --cli-binary-format raw-in-base64-out --invocation-type RequestResponse --function-name parameters-and-types-stack-GetNumberFunction-5bfi9R7rI0ej --payload 123.456 outputfile.txt
• input number - from file
• aws lambda invoke --cli-binary-format raw-in-base64-out --invocation-type RequestResponse --function-name parameters-and-types-stack-GetNumberFunction-5bfi9R7rI0ej --payload file://events/event-number.txt outputfile.txt
• input Array
• aws lambda invoke --cli-binary-format raw-in-base64-out --invocation-type RequestResponse --function-name parameters-and-types-stack-GetScoresByNameFunction-CcXKamLclrTc --payload file://events/event-list.txt outputfile.txt
• input Json Map
• aws lambda invoke --cli-binary-format raw-in-base64-out --invocation-type RequestResponse --function-name parameters-and-types-stac-SaveEmployeeDataFunction-xtSfPd87MDGI --payload file://events/event-map.json outputfile.txt
• input POJO
• aws lambda invoke --cli-binary-format raw-in-base64-out --invocation-type RequestResponse --function-name parameters-and-types-stack-GetClinicalDataFunction-biyr6RLO7sGj --payload file://events/event-pojos.json outputfile.txt

Gateway to DynamoDB implementation without Lambda

Timing compare:

1. Lambda-less approach

• Create new order
  • First request
    • Response code: 201 (Created); Time: 455ms; Content length: 2 bytes
  • Other requests
    • Response code: 201 (Created); Time: 241ms; Content length: 2 bytes
• Read all orders
  • Response code: 200 (OK); Time: 262ms; Content length: 537 bytes

2. Lambda approach

• Create new order
  • First request
    • Response code: 200 (OK); Time: 10993ms; Content length: 18 bytes <- COLD start
  • Other requests
    • Response code: 200 (OK); Time: 277ms; Content length: 18 bytes
• Read all orders
  • Response code: 200 (OK); Time: 9628ms; Content length: 656 bytes <- COLD start
  • Response code: 200 (OK); Time: 386ms; Content length: 656 bytes

Section 8: Logging and Error Handling

94. Test Log4j logs

• Correct Data
  • aws lambda invoke --cli-binary-format raw-in-base64-out --invocation-type Event --function-name patient-checkout-stack-PatientCheckoutLambdaFuncti-7lREXMY1aWxR --payload file://events/event.json outputfile.txt
• Corrupt data
  • aws lambda invoke --cli-binary-format raw-in-base64-out --invocation-type Event --function-name patient-checkout-stack-PatientCheckoutLambdaFuncti-7lREXMY1aWxR --payload file://events/event-corrupt.json outputfile.txt
• View logs
  • sam logs -n PatientCheckoutLambdaFunction --stack-name patient-checkout-stack
  • sam logs -n PatientCheckoutLambdaFunction --stack-name patient-checkout-stack -s "10min ago" -e "2min ago"
  • sam logs -n PatientCheckoutLambdaFunction --stack-name patient-checkout-stack --tail

Assignment 4.2: Corrupt Data Test (#11, #9)

• aws lambda invoke --cli-binary-format raw-in-base64-out --invocation-type Event --function-name student-grading-stack-StudentsUpdateMonitoringFunc-dbf5rxuO6G22 --payload file://events/event-corrupt.json outputfile.txt

12.1 Optimize cold start performance for AWS Lambda - AwsCredentialsProvider

AWS Recommendations:

• Optimizing cold start performance for AWS Lambda
• Introducing AWS Common Runtime HTTP Client in the AWS SDK for Java 2.x

12.2 AWS Common Runtime HTTP Client

1. With Netty-NIO-Client (netty-nio-client)
