A review of cloud computing system and its security problems

Cloud computing has the ability to provide consumers with cost-effective and more flexible services on demand via the network. It expands the organization's capabilities without the need to hire new employees, invest in new infrastructure, or purchase new software. Because of the scalability of resources, cloud computing has expanded significantly in recent years, and it now seems to be a fast-growing sector of the IT business. By analyzing policy failure or malicious behavior, the dynamic and scalable nature of cloud computing presents security difficulties in their administration. The comprehensive design of cloud computing architecture is examined in this article, which includes deployment models, service models, cloud components, and cloud security. Furthermore, this research highlights the security issues in cloud computing during data transmission and proposes a feasible method to mitigate the possible risks. The aim of a Trusted Third Party (TTP) is to provide security features that are adequate in cloud computing. The Public Key Infrastructure (PKI) is a cryptography-based security solution that works with Single-Sign-On (SSO) and Lightweight Directory Access Protocol (LDAP) to guarantee the integrity, confidentiality, availability, and authenticity of communications and data.
