An enterprise plans to move a legacy application that requires specific operating-system configurations and custom libraries to the AWS Cloud. Which AWS service should the enterprise use to migrate the application with minimal architectural changes?
AWS Lambda
Amazon EC2
AWS Elastic Beanstalk
AWS Fargate
Legacy applications that depend on precise OS settings and custom libraries need direct access to the operating system and full control of the software stack. Amazon EC2 provides virtual machines (instances) where customers can choose the operating system, install required libraries, and configure the environment as needed. In contrast, AWS Lambda (serverless functions) and AWS Fargate (serverless containers) abstract away the underlying servers, limiting OS-level control. AWS Elastic Beanstalk simplifies deployments but still runs on managed environments that are less customizable than direct EC2 instances, making EC2 the best fit for this scenario.
