The concept of cloud computing is a major shift from the company's traditional way of thinking about IT resources. Simply put, cloud computing is the delivery of computer services over the Internet. The “cloud” turns the IT infrastructure into a utility: it allows you to “connect” to the infrastructure via the Internet and use computing resources without installing and maintaining it on site. These services are divided into three main categories: infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS). Also, the concept of "cloud" offers us various benefits in business such as cost savings, increased mobility and resilience and a wide range of access to services. With all the speed, efficiency, and innovation that come with cloud computing, there are naturally risks. Security has always been a big concern in the cloud, especially when it comes to sensitive data. The development of cloud computing is best illustrated by the fact that more than a hundred million users around the world use cloud services every day.
