Serverless Architecture of WordPress on AWS

Abstract: Serverless architecture provides a modern, scalable, and cost-effective solution for hosting WordPress websites, eliminating the complexities associated with traditional server-based setups. By leveraging AWS services such as AWS Lambda for executing backend logic, Amazon API Gateway for routing HTTP requests, Amazon S3 for hosting static assets, and Amazon RDS for managing the relational database, this architecture supports dynamic scalability, high availability, and operational efficiency. This paper delves into the design and implementation of deploying WordPress in a serverless environment, offering insights into the technical workflow and integration of serverless components. The study also examines the benefits of automatic scaling, reduced infrastructure costs, and minimized maintenance efforts while addressing challenges such as cold starts, integration complexities, and latency issues. Through a detailed analysis, the paper highlights the potential of serverless architecture in transforming traditional WordPress deployments into highly efficient and resilient systems, offering significant value for developers, businesses, and end-users.
