SaaS (software as a service)
this type of cloud computing transmits programs to thousands of users through a browser. In the eyes of users, this will save the cost of server and software authorization; from the supplier's point of view, it is enough to maintain only one program, which can reduce costs. Salesforce.com is the most famous company for such services so far. SAAS is commonly used in human resource management programs and ERP. Google Apps and zoho office are similar services.
utility computing
this idea has been launched for a long time, but I know that I was new to Amazon.com, sun, IBM, and other companies that provide storage services and virtual servers recently. This cloud computing creates a virtual data center for the IT industry so that it can combine memory, I/O devices, storage and computing capabilities into a virtual resource pool to provide services for the entire network.
network services
close relationships with SaaS allow network service providers to provide APIs for developers to develop more Internet-based applications, rather than single-host applications.
platform as a service
another type of SAAS, in which cloud computing provides the development environment as a service. You can use middlemen devices to develop your own programs and transmit them to users through the Internet and their servers.
MSP (Management Service Provider)
one of the oldest cloud computing applications. This type of application is intended for the IT industry rather than end users. It is often used for mail virus scanning and program monitoring.
commercial service platform
this type of cloud computing provides a platform for interaction between users and providers. For example, the user's personal expenditure management system can manage the expenses of users and coordinate the various services they subscribe to based on their settings.
Internet Integration
enterprises that provide similar services on the Internet are integrated so that users can conveniently compare and select their own service providers.
