Abstract
Cloud computing is the on-demand availability of PC framework resources. Especially information storage and handling power, without direct unique administration by the customer. It has provided customers with public and private computing and data storage on a single platform across the Internet. Aside from that, it faces several security threats and issues, which may slow down the adoption of cloud computing models. Cloud computing security threats, difficulties, strategies, and solutions are discussed in this paper. Numerous people raised security concerns in a previous survey. Another survey looks at the cloud computing architectural model, and a few of them detail security challenges and techniques. This article brings together all the security concerns, difficulties, techniques, and solutions in one place.
