Hybrid Cloud Deployment Using AWS EC2 and On-Premises Virtual Machine

Abstract: Cloud computing has fundamentally transformed how modern applications are built and deployed. This project presents a practical implementation of hybrid cloud architecture that integrates Amazon Web Services (AWS) Elastic Compute Cloud (EC2) with a locally hosted Oracle VirtualBox virtual machine running Ubuntu Linux. The system demonstrates how organizations can leverage the benefits of cloud infrastructure — including scalability, remote accessibility, and cost efficiency — while retaining on-premises control over sensitive workloads. The web application was deployed using the Apache HTTP Server on the AWS EC2 instance, with secure remote administration established via the SSH protocol. The hybrid architecture supports data backup and disaster recovery through cloud storage services (Amazon S3), distributed workload management via AWS Virtual Private Cloud (VPC), and system monitoring through AWS CloudWatch. Comprehensive unit, integration, system, and performance testing confirmed that all components function correctly. The project validates that hybrid cloud deployment is a practical, cost-effective approach for modern application hosting, and provides a reproducible reference implementation for cloud professionals and academic practitioners.
