Embodiment Construction

[0035] In the present invention, an edge cloud composed of corresponding server nodes is set in the cloud to form a layered distributed cloud computing architecture composed of "core cloud", "edge cloud" and user terminals, such as figure 2 shown. By setting computing nodes between the core cloud computing center and the terminal, the traffic at the exit of the core cloud is reduced, thereby reducing the delay and ensuring the QoS of cloud computing.

[0036] Core cloud: It has powerful computing and storage capabilities, and under the support of edge cloud, it cooperates with each other to provide users with transparent cloud computing services quickly and elastically. The core cloud is a cloud computing service center composed of server clusters with powerful storage and computing capabilities. Users use the services provided by the core cloud according to their own needs.

[0037] Edge cloud: It is composed of server nodes distributed in different networks and regions, pr...

Abstract

The invention discloses a layered distributed cloud computing architecture and a service delivery method. The architecture is composed of a core cloud, an edge cloud and a terminal. The core cloud is a cloud computing service center composed of servers with powerful storage and computing capacity; the edge cloud is composed of server nodes distributed in different networks and regions and is connected with the core cloud by backbone network, and the terminal is an entity which uses a cloud computing service provided by the core cloud and edge cloud. The core cloud and the edge cloud work together to provide the cloud computing service for terminal users and uses relevance of data transmitted by the core edge and the terminal to process the data so as to reduce traffic. In the invention, network flow in most of cloud computing is confined to the local network between the edge and the terminal, thus lowering traffic of the backbone network, effectively avoiding the problems of network congestion, high latency and the like in the existing centralized cloud computing mode and improving user experience.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a layered distributed cloud computing system structure and a service providing method. By introducing the concept of edge cloud, the dependence of cloud computing on network bandwidth is reduced, and the QoS of cloud computing is improved. Background technique [0002] Cloud computing (Cloud Computing) is a more reasonable and effective service provision and operation mode in a computer network. In this mode, various computing, storage and other services that are traditionally located locally are provided by large-scale, centralized cloud computing services. replace. In cloud computing, users can conveniently and transparently use various computing, storage and other resources provided by cloud computing service providers on demand. These computing resources can be quickly provided and released, which reduces the cost of purchase, management and maintenance for enterprises or in...
