If there are a large number of bare metal machines that need to be allocated the same type of operating system, each time a bare metal machine to be allocated with the same type of operating system is allocated, the bare metal machine must obtain the Image corresponding to the same Image ID from the network node, resulting in a gap between the bare metal machine and the second server. The network overhead is large, and the network overhead between the bare metal and the network node storing the image is large

Embodiment Construction
[0034] Embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.
[0035] In order to better understand the communication method, device, and server disclosed in the embodiments of the present invention, the network architecture applicable to the embodiments of the present invention will first be described below. See figure 1 , figure 1 It is a schematic structural diagram of a communication system disclosed in an embodiment of the present invention. Such as figure 1 As shown, the communication system includes a first server, a second server and at least one bare metal. The communication system also includes at least one rack, which is used to carry at least one bare metal. Minios runs in the memory of each bare metal, and the Minios is a small operating system that provides communication services based on the Hyper Text Transfer Protocol (Hyper Text Transfer Protocol, HTTP) protocol for the bar...

The embodiment of the present invention discloses a communication method, device, and server. The method includes: sending a first notification message including an Image identifier to the first target bare metal, and the first notification message is used to instruct the first target bare metal to send a message carrying an image to the second server. An Image acquisition request identified by Image, the Image acquisition request is used to instruct the second server to send the access address of the network node storing the Image corresponding to the Image identification to the first target bare metal; after the first target bare metal acquires the Image from the network node, Receive the first response message sent by the first target bare metal; send a second notification message including the bare metal identifier to the second target bare metal, and the second notification message is used to instruct the second target bare metal to acquire the Image from the first target bare metal corresponding to the bare metal identifier . By adopting the embodiment of the present invention, the network overhead between the bare metal and the second server and the network node storing the Image can be saved.
Description
technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method, device and server. Background technique [0002] Cloud computing (Cloud Computing) provides a computing model, mainly through the cloud service provider to provide users with cloud service resources, and the user pays the cloud service provider according to the usage of cloud service resources such as computing and storage obtained on demand. Cloud service providers manage and schedule these cloud service resources in a unified manner through the Cloud Computing Management Platform. In scenarios such as high-performance computing, cloud computing needs to provide bare metal services (BaremetalService, BMS) to users. In the cloud computing management platform, a bare metal management component (Baremetal Management Component, BMC) is usually used to manage the bare metal in the cluster. The BMC runs in the first server, and the BMC is ...
