Deploying a WordPress Site Using Docker and AWS RDS

Abstract: In modern cloud computing environments, deploying scalable and reliable web applications is essential for ensuring performance, availability, and efficient resource management. Traditional web hosting methods often involve manual configuration and dependency management, which can lead to inconsistencies across deployment environments. Containerization technologies and cloud services provide a solution to these challenges by enabling automated deployment, portability, and scalability.

This paper presents the deployment of a WordPress website using Docker containerization on an Amazon EC2 instance integrated with Amazon Relational Database Service (RDS) for database management. WordPress is a widely used Content Management System (CMS) that allows users to create and manage dynamic websites. By deploying WordPress inside a Docker container, the application environment becomes isolated, portable, and easy to maintain. Amazon EC2 provides scalable cloud infrastructure to host the application, while Amazon RDS offers a managed MySQL database service for secure and reliable data storage.

The proposed architecture follows a two-tier model consisting of an application layer and a database layer. The application layer hosts the Docker container running WordPress on an EC2 instance, while the database layer uses Amazon RDS to store website content and user data. Security groups and network configurations ensure secure communication between the two components. Elastic IP is used to provide consistent external access to the hosted website.
