Abstract: In the digital age, where businesses and individuals increasingly rely on online presence, the need for secure,scalable, and reliable website hosting has become paramount. WordPress, as the most widely used contentmanagement system (CMS), powers over 40% of websites worldwide. However, hosting a WordPress sitesecurely requires more than just basic installation—it demands thoughtful planning, strong architecture, andcontinuous monitoring. This project, titled “Hosting a Secure WordPress Website on AWS”, is designed toaddress these challenges by leveraging the powerful services offered by Amazon Web Services (AWS) to build asecure, high-performance hosting environment for a WordPress website.The main objective of this project is to implement a secure hosting solution using AWS infrastructure componentssuch as EC2 (Elastic Compute Cloud), VPC (Virtual Private Cloud), RDS (Relational Database Service), Route53, CloudFront, and S3. The deployment begins with setting up a customized VPC to create isolated public andprivate subnets, ensuring that web servers and databases are segmented for security. An EC2 instance is launchedin the public subnet with a LAMP (Linux, Apache, MySQL, PHP) stack configured to support WordPress. Thedatabase layer is hosted securely using Amazon RDS, allowing scalability and better data protection. Using AWSIdentity and Access Management (IAM), strict access controls are enforced to prevent unauthorized use of cloudresources.Security remains the central focus throughout the project. To begin with, an SSL certificate is configured usingAWS Certificate Manager and applied through Apache or NGINX web servers to ensure encryptedcommunication over HTTPS. Security Groups are carefully configured to limit access only to necessary ports,such as 22 (SSH), 80 (HTTP), and 443 (HTTPS). The EC2 instance is further hardened by disabling root login,configuring key-based SSH access, and regularly updating packages to mitigate vulnerabilities. At the applicationlevel, WordPress is secured by setting proper file permissions, disabling file editing from the dashboard, andinstalling trusted security plugins such as Wordfence and iThemes Security. The project also emphasizes backup and disaster recovery mechanisms. Scheduled automated backups of boththe file system and the database are configured using Amazon S3 and AWS Backup services. AmazonCloudWatch and CloudTrail are implemented to monitor resource performance and track user activities,respectively, enabling quick identification of suspicious behavior or system failures. Additionally, CloudFront(AWS’s CDN service) is integrated to enhance website performance, improve content delivery speed, and add anextra layer of protection through AWS Shield against DDoS attacks.From a performance standpoint, several optimization measures are taken. Caching mechanisms are implementedusing plugins like W3 Total Cache or WP Super Cache, and browser caching is enabled via .htaccessconfiguration. Load testing and benchmarking tools are used to analyze website performance under various trafficconditions, ensuring the infrastructure is robust and scalable.This project not only demonstrates technical proficiency in deploying WordPress on cloud infrastructure but alsoemphasizes best practices in security, system administration, and DevOps. It showcases a comprehensive solutionthat blends automation, protection, and monitoring into a unified hosting strategy. The outcome is a secure,scalable, and maintainable environment suitable for production websites, business blogs, e-commerce platforms,or personal portfolios.By hosting WordPress on AWS with a focus on security, this project equips developers and IT professionals withthe skills and knowledge needed to build cloud-based applications that can withstand real-world security threats and performance demands. As cloud computing continues to dominate IT infrastructure strategies, projects likethis offer a vital learning opportunity in building modern, resilient web applications.
