A method for connecting a physical machine to a cloud platform

Abstract

The present invention provides a method for connecting a physical machine to a cloud platform, including S1, connecting the physical machine to the cloud platform through a bare-metal switch and a layer-2 switch; S2, creating a VXLAN and / or GRE virtual network in the cloud platform, and After the virtual network distributes the VLAN ID, the VLAN ID is stored in the database; S3, the physical network card information is searched in the database of the cloud platform, and a virtual network card corresponding to the physical network card information is created; S4, the cloud platform dynamically configures the VLAN ID Go to the port corresponding to the network card of the physical machine in the bare metal switch; S5, convert the VLAN ID into a network ID suitable for the virtual network in the layer 2 switch. In the present invention, by dynamically configuring the VLAN ID into the bare-metal switch, and converting the VLAN ID and the virtual network in the cloud platform on the layer-2 switch, the smoothness of physical machine access to the cloud platform is realized, and the physical Data access efficiency and security between machines and virtual machines, saving public network IP resources.

Description

technical field [0001] The invention relates to the field of cloud technology, in particular to a method for a physical machine to access a cloud platform. Background technique [0002] With the rapid development of cloud computing and the continuous increase of business volume, on the one hand, more professional users and cutting-edge industries start to use the cloud, so the stability and performance requirements of the cloud host are more stringent. Compared with virtual machines, physical machines have better stability and performance. It is an urgent need for users to directly connect physical machines to the cloud platform and deliver them to users as ordinary virtual machines. On the other hand, traditional manufacturers continue to try to access the cloud platform in order to reduce costs and optimize technical architecture. However, most traditional cloud service providers use physical machines to meet business needs. How to smoothly connect physical servers to the...

AI Technical Summary

Problems solved by technology

When the number of physical machines is very large, it is obvious that a large number of external network IPs will need to be allocated, resulting in a waste of external network IP resources

In addition, there is a bottleneck of the upper limit of VLAN ID, the maximum number is only 4096, so when more physical machines are connected, it is impossible to assign a VLAN ID to each physical machine

In addition, there are many types of virtual networks in the cloud platform, so Layer 2 communication between multiple network types cannot be realized
