1.2.1 Background introduction
As a new economic growth model, cloud computing is attracting more and more people's attention. The seismic changes it brings bring new opportunities and challenges, not just in the cloud but also in the environment surrounding the cloud. Therefore, understanding the basic knowledge is crucial to mastering various knowledge and skills of cloud computing. Cloud computing includes three aspects, namely infrastructure, platform services and software services. Among them, infrastructure refers to the services provided by resource providers such as cloud servers, networks, and storage; platform services refer to services provided by manufacturers such as AWS (Amazon Web Services), Google Cloud Platform, and Microsoft Azure; and software services are provided by cloud software providers. provided by the company.
Generally speaking, the most widely used cloud computing is software as a service (SaaS) based on virtualization technology, such as Microsoft Office 365, Google G Suite, Amazon Web Services, etc. These services can help users easily perform functions such as file storage, social media communication, and work collaboration. However, due to factors such as hardware resource limitations and network connection instability, the performance and availability of these services are unstable. How to create value for customers by effectively utilizing cloud resources and improving service quality is also the key to cloud computing.
