Which AWS service should the company use to meet these requirements?

Explanations:

AWS Config is a service for assessing, auditing, and evaluating the configurations of AWS resources. It helps in compliance management but does not facilitate quick application deployment or reduce management complexity.

AWS Elastic Beanstalk is a Platform as a Service (PaaS) that allows developers to quickly deploy and manage applications without worrying about the underlying infrastructure. It simplifies resource management and supports multiple programming languages, making it ideal for rapid deployment.

Amazon EC2 provides Infrastructure as a Service (IaaS) and allows for flexible computing resources. However, it requires more management and configuration, increasing complexity compared to managed services like Elastic Beanstalk.

Amazon Personalize is a machine learning service for building personalized recommendation systems. It does not relate to application deployment or management of AWS resources, thus not suitable for the stated requirements.
