Cloud computing is a technical model with on-demand network access, delivering various types of services, providing resources such as memory storage, applications, networking, databases, servers, etc. All these resources always keep with us but with one condition: “the internet.” The major purpose of this chapter is to know the security and services requirements and their solutions in a cloud computing environment. This rigorous research extensively explores the complex relationship between service delivery and security. It also looks at the issues and potential fixes for providing services that are trustworthy, efficient, and safe. Because of the accelerated pace of technological advancement, the networked nature of systems, and the rising reliance on internet services, the potential of threats and vulnerabilities has increased significantly. After that, the authors focus on what types of services are given in the cloud where each type of service provides different options like efficiency, accessibility, savings, flexibility, opportunity, innovation, and many more.
