Method for accessing physical machine to cloud platform

Abstract

The invention provides a method for accessing a physical machine to a cloud platform. The method comprises S1, accessing the physical machine to the cloud platform through a bare switch and a layer-2 switch; S2, building a VXLAN and / or RGE virtual network in the cloud platform, allocating VLAN ID for the virtual network and then storing the VLAN ID in a database; S3, finding physical network card information in the database of the cloud platform and building a virtual network card corresponding to the physical network card information; S4, dynamically configuring the VLAN ID to a port corresponding to a physical machine network card in the bare switch by the cloud platform; and S5, converting the VLAN ID into a network ID adaptive to the virtual network in the layer-2 switch, and realizing conversion of the VLAN ID and the virtual network in the cloud platform at the layer-2 switch. Therefore, the smoothness of accessing the physical machine to the cloud platform is realized, the access efficiency and security of data between the physical machine and the virtual machine are improved, and the public network IP resources are saved.

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
