Which AWS service is used for deploying and scaling web applications on servers like Apache?

AWS Elastic Beanstalk is designed specifically for deploying and managing web applications and services. It provides an easy-to-use platform for developers to upload their applications without worrying about the underlying infrastructure. Elastic Beanstalk automatically handles the deployment, from capacity provisioning, load balancing, and scaling to application health monitoring.

This service supports a variety of application platforms, including Java, .NET, PHP, Node.js, Python, Ruby, and Go, and it can work with popular web servers like Apache and Nginx. By simplifying the deployment process, Elastic Beanstalk allows developers to focus on writing code rather than managing the environment in which their applications run.

In contrast, while AWS Lambda enables users to run code without provisioning servers, it is better suited for event-driven applications and microservices, as it lacks the full support for web application frameworks that Elastic Beanstalk provides. Amazon EKS (Elastic Kubernetes Service) is more focused on managing Kubernetes clusters rather than direct web application deployment, and Amazon RDS (Relational Database Service) pertains specifically to database management rather than application deployment. This distinction underscores why Elastic Beanstalk is the most fitting choice for deploying and scaling web applications that rely on servers like Apache.
