Abstract: – Cloud computing has transformed the way computing resources such as servers, storage, and applications are delivered by providing on-demand access through the internet. Virtualization is a fundamental technology that enables cloud computing by allowing multiple virtual machines to operate on a single physical server, thereby improving efficiency and flexibility.

The primary objective of this study is to analyze how virtualization in AWS EC2 supports efficient resource utilization, scalability, performance optimization, and cost reduction. The case study approach is adopted to gain an in-depth understanding of virtualization practices in a real operational setting. Data for the study is collected through observation of EC2 instances, analysis of system configurations, monitoring of resource usage, and review of relevant AWS documentation and existing research literature.The analysis focuses on key aspects such as virtual machine provisioning, scalability features, performance behavior, and cost efficiency of AWS EC2 services. The findings of the study indicate that virtualization enables dynamic allocation of computing resources, improves system availability, and reduces the need for physical hardware. AWS EC2 provides a flexible and reliable platform that allows organizations to scale resources according to workload demands while maintaining optimal performance. The results further demonstrate that virtualization enhances operational efficiency and simplifies infrastructure management, making cloud computing more accessible and cost- effective.

INTRODUCTION

Cloud computing is a technology that allows users to access computing resources such as servers, storage, and applications through the internet.

Instead of buying and maintaining physical hardware, users can use these resources whenever needed and pay only for what they use. Due to its flexibility, scalability, and cost benefits, cloud computing is widely used by organizations, educational institutions, and businesses.

Virtualization is the core technology that makes cloud computing possible. It allows multiple virtual machines to run on a single physical server by sharing hardware resources. Each virtual machine works independently, even though it uses the same physical system. Virtualization helps in better use of hardware, reduces energy consumption, and simplifies system management. It also supports important cloud features such as scalability and efficient resource sharing.

Amazon Web Services (AWS) is one of the leading cloud service providers. AWS Elastic Compute Cloud (EC2) offers virtual servers, known as instances, which can be easily created, managed, and scaled based on user requirements. AWS EC2 provides a real-world environment to study how virtualization works in cloud computing. It allows users to adjust computing resources according to workload demands while maintaining good performance and cost efficiency. Although virtualization offers many benefits, it also faces challenges such as managing resources efficiently, ensuring security, and maintaining performance. To understand how these challenges are handled in practice, this research uses a case study approach. The study focuses on virtualization in cloud computing using AWS EC2.

The main objective of this research is to analyze how virtualization in AWS EC2 improves resource utilization, scalability, performance, and cost efficiency. By studying a real AWS EC2 environment, this research provides practical understanding of the role of virtualization in modern cloud computing systems.
