AWS Lambda now supports Java 8 (Corretto)



You can now develop AWS Lambda functions using Java 8 (Corretto). [Amazon Corretto 8](/corretto/) is a no-cost, production-ready distribution of OpenJDK 8 that comes with long-term support. Lambda functions written in Java 8 (Corretto) run on [Amazon Linux 2](/amazon-linux-2/), the latest generation of Amazon Linux. You can read more about the Java programming model in the [AWS Lambda documentation]( Corretto 8 is designed as a drop-in replacement for OpenJDK 8\. Amazon provides patches for Corretto 8 which are not yet integrated in the corresponding OpenJDK update projects. These patches include security fixes, performance enhancements (for example, speeding up frequently-used functions), garbage collection scheduling, and preventing out-of-memory situations, as well as improved monitoring, reporting, and thread management. To get started, upload your code through the AWS Lambda console and select the Java 8 (Corretto) runtime. You can also use AWS CLI, [AWS Serverless Application Model (SAM)](/serverless/sam/) and [AWS CloudFormation](/cloudformation/) for deploying and managing your serverless applications authored in Java 8 (Corretto). To migrate existing AWS Lambda functions running in OpenJDK 8 to Java 8 (Corretto), update your code to be compatible with Amazon Linux 2, and then update the function runtime to Java 8 (Corretto). The Java 8 (Corretto) runtime is available in [all Regions where Lambda is available](/about-aws/global-infrastructure/regional-product-services/). Please visit our [product page](/lambda/) for more information about AWS Lambda or log in to the [AWS Lambda console]( to get started.
