Remote Code Execution (RCE) systems are an important factor in the current practice of programming education, online examinations, and competitive coding. Traditional RCE architectures, however, experience scalability limitations, large operational costs and security risks as a result of running untrusted code via persistent servers or virtual machines. This paper presents a cloud-native and serverless Remote Code Execution system constructed on the Amazon API Gateway, AWS Lambda, and Docker container images. The suggested system executes Python, Java, C++ in isolated and short-lived containers to guarantee security and statelessness. A React.js frontend powered by the Monaco Editor provides an interactive IDE-like experience with examination-oriented restrictions, including copy-prevent and paste-prevent features. Experimental analysis proves reliable execution, high scalability, low cold-start latency, and sandbox isolation. The findings confirm that serverless solutions are an economical, secure, and scalable substitute of traditional RCE application.
