The models of Platform as a Service (PaaS), Infrastructure as a Service (IaaS), and Software as a Service (SaaS) are also covered in detail. There is a thorough discussion of the security risks related to cloud computing, including compromised passwords, data breaches, compromised interfaces and APIs, exploited system vulnerabilities, and account hijacking. The document highlights how crucial it is to comprehend and reduce these security threats in order to guarantee the stability and integrity of cloud computing platforms. In the IT sector, cloud computing has emerged as one of the most popular subjects. The computing environment has altered due to the cloud model's utilization of computing as a resource. Businesses and individuals have been drawn in by the promises of vast scalability, reduced costs, and enhanced reliability. It increases information technology's capabilities. Cloud computing has experienced significant growth in the field of information technology during the past several years. Concern over information security is growing as more and more data on people and businesses is being stored on cloud servers. Numerous software companies, such as Microsoft, are collaborating to create cloud services. Customers are hesitant to move their business to the cloud, despite the buzz around it.
