Computing services, that is, cloud services. China Cloud Computing Service Network is defined as a cloud computing product that can be used as a service. Including cloud hosting, cloud hosting, cloud development, cloud testing and comprehensive products. Users can obtain the required resources and services in an on-demand and extensible way through the network.
As we all know, the service types of cloud computing can generally be divided into three levels: IaaS, PaaS and SaaS. These three levels constitute the overall architecture of cloud computing technology, which may include some virtualization technologies and applications, automated deployment, distributed computing and other technologies. The advantage of this technical architecture is that it can show excellent parallel computing ability and large-scale scalability and flexibility.
Service mode:
Cloud service providers set up all the network infrastructure, software and hardware platforms needed for the informatization of small and medium-sized enterprises, and are responsible for a series of services such as early implementation and late maintenance. Enterprises can enjoy information systems through the Internet without purchasing software and hardware, building computer rooms and recruiting IT personnel, and only need to pay one-time project implementation fees and regular software rental service fees in advance.
Service providers can ensure the security and confidentiality of each enterprise data through effective technical measures. There is basically no difference between the cloud service mode adopted by enterprises and the self-built information system, but IT saves a lot of expenses for purchasing IT products, technologies and maintenance and operation. Using the information system is as easy as turning on tap water, which greatly reduces the threshold and risk of informatization of small and medium-sized enterprises.
