Amazon Corretto
Amazon Corretto is a no-cost, multiplatform, production-ready distribution of the OpenJDK (Java Development Kit). It provides long-term support with security updates and performance enhancements, ensuring compatibility with Java SE standards. Amazon uses Corretto internally for its own services and offers it as a reliable Java runtime for developers and enterprises.
Developers should use Amazon Corretto when they need a free, enterprise-grade Java runtime with predictable updates and support, especially for cloud-based or AWS-hosted applications. It is ideal for production environments requiring stability, security patches, and compatibility with Java applications, as it eliminates licensing costs and reduces vendor lock-in compared to Oracle JDK.
