Cloud computing has become increasingly popular due to its scalability and cost-effectiveness, but its adaptability and flexibility can lead to security challenges when examining failed policies or malicious activities. Using the network, cloud computing has the ability to offer users more adaptable and cheaper services. Cloud computing has expanded dramatically over the past several years thanks to the resources' scalability, giving the impression that this area of the IT industry is growing quickly. Cloud computing has increased the number of security challenges, leading to users losing faith in it due to a lack of security. There are many security concerns with cloud computing, including multi-tenancy, elasticity, security performance, and optimization. This paper provides a thorough analysis of the cloud computing architecture, including deployment tactics, service level agreements, cloud components, and security. It also covers the security issues associated with transferring data to the cloud and provides a practical solution to mitigate any potential risks. It dynamically increases the organization's capacity without spending money on new hardware, personnel, or software licenses. We shall talk about a few clouds computing issues in this paper. It also examines some of the security measures now in use for cloud computing security, educating researchers and professionals about various security risks. This paper seeks to advance our understanding of cloud computing techniques. This paper's main goal is to act as a reference and manual for ongoing research initiatives. In-depth applications that have already benefited from cloud apps are investigated in the paper
