 ## Project Description
 The code example include storing and retrieving product from the Amazon DynamoDB. I put Amazon API Gateway in front of my Lambdas.
 
-I explore the following ways to run Spring Boot application with AWS Lambda Java or Customer Runtime with GraalVM Native Image:  
-
-- Lambda with Java 21 Runtime and Spring Boot 3.2 and aws-serverless-java-container   
-- Lambda with Java 21 Runtime and Spring Boot 3.2 and Spring Cloud Function   
-- Lambda with Java 21 Runtime and Spring Boot 3.2 and Lambda Web Adapter

+
+sudo yum install java-21-amazon-corretto

+git clone https://github.com/Vadym79/AWSLambdaJavaDockerImage.git
 
 Compile and package the Java application with Maven from the root (where pom.xml is located) of the project
-mvn clean package
