Serverless Java leverages cloud computing to enable developers to concentrate on business logic rather than infrastructure management, as the infrastructure provider handles scaling, resource management, and security. This setup allows developers to build applications that are highly available and scalable, without directly managing servers, though servers remain abstractly present. Serverless applications are event-driven, stateless, and cost-effective, with reduced maintenance and faster time to market. However, challenges include potential higher costs for stable workloads, complexity in system integration, time limitations on function execution, vendor lock-in, and cold start latencies due to Java's larger runtime. Despite these challenges, serverless Java is advantageous for applications reliant on Java libraries, existing Java codebases, and can benefit from tools like GraalVM to mitigate cold start issues. Additionally, error tracking and management can be streamlined using tools like Rollbar, enhancing confidence in deploying production code.
