Abstract
Cloud security term refers to a broad field that has to do with the protection of data and cloud systems. Cloud security has historical roots that include ciphers, subterfuge, and other practices whose goals were to protect the confidentiality of written messages. In our era, cloud security is generally understood to involve domains that are involved in the security of IT systems as well as with the non-IT processes that are in interaction with IT systems. The objective of cloud security is to protect data as well as cloud systems from unauthorized access, use, disclosure, disruption, modification, or destruction. We will create public cloud using openshift cloud then apply Advanced Encryption Standard algorithm on file, which will store on cloud storage and also calculate encryption and decryption time.
