Cloud computing refers to the management of data and servers and the provision of technology services using cloud computing technology. It is commonly used to store large amounts of data on cloud platforms. As a result, it is essential to safeguard data in various formats such as text, audio, video, and others. This paper presents a research study on cloud security, focusing on AWS, the most trusted cloud computing provider. AWS offers not only cloud security but also cloud storage services. The document addresses several key security challenges, including virtualization security, data storage in the cloud, and risk tolerance assessment in cloud computing. As the cloud grows, it is increasingly important to understand and implement effective security measures to protect sensitive information and maintain trust in cloud-based services.
