Cloud computing is an advanced technology that provides access to different services via the internet. These services include applications such as servers, networking, data storage, databases, and software. Instead of storing files on local storage device, cloud-based storage makes it possible to store files in a secure database. As long as an electronic device has access to the web, it has access to data and the software programs to run it. For this reason, this technology is very popular for institutions and individuals for many reasons such as cost, production, efficiency and speed. However, with the advantages of cloud computing, some security risks also arise. At the beginning of these security risks are data breaches and data losses caused by malicious software applications. In this study, data replication is discussed in order to solve security breaches in cloud computing technologies.
