Embodiment 1

[0172] Such as Figure 12 As shown, this embodiment shows a schematic diagram of a final Openstack design of multiple network areas. Contains three control nodes, two network areas, each network area contains several network nodes, and several AZs, each AZ contains several computing nodes.

[0173] As a further improvement of an embodiment of the present invention, for the External network address, if the customer does not distinguish between the External network and the Public network, considering that the operator may only assign a public network IP address of a network segment to the customer, the address network can be A segment divides multiple subnets, and different regions allocate IP addresses in different ranges within the segment. When the number of regions is too large, considering subnet division, the IP addresses of all 0s and all 1s of the subnet will be wasted. A feasible solution is to use a hardware firewall to set the External network in different areas to ...

Embodiment 2

[0180] Such as Figure 13 As shown, select several hosts from all Openstack hosts as control nodes. Divide the remaining machines into various areas according to the previous planning of the network area. Select some nodes from each area as network nodes, and some nodes as computing nodes. After the selection is complete.

[0181] Deployment of data network and external network such as Figure 14 As shown, the external network is connected to the external network router, the rest are data networks, and the management network is as follows Figure 15 shown.

[0182] Such as Figure 16 As shown, various services required are installed on the selected control nodes. Including database, keystone, horizon, Neutron controller, nova service, etc. Then configure the designed network area information table areas, and add the hosts in the divided areas to the area_host table.

[0183] According to the previous logical topology planning, build the underlying physical network conn...

Abstract

The invention provides an openstack platform multi-network-area supporting system and method, and relates to the technical field of cloud computing management platforms. The method includes deployinga plurality of network areas according to the physical topology or the logic topology of the Openstack platform, realizing the data network communication in the plurality of network areas, and settingthe corresponding area attributes for each network area; and determining the network node and the computing node corresponding to each network area according to the set area attributes, wherein the control node divides the network nodes and the computing nodes in the Openstack platform into corresponding network areas according to the area attributes corresponding to each network area. Accordingto the invention, the requirement for physical isolation of the customer on the plurality of areas is met, the capability of distinguishing the network nodes and the capability of providing differentreliability services can be achieved, the matching with the AZ and the HA of the computing nodes is better realized, and a whole set of differentiation service is provided for the user.

Description

technical field [0001] The invention relates to the technical field of cloud computing management platforms, in particular to a system and method for an Openstack platform supporting multiple network areas. Background technique [0002] Such as figure 1 As shown, the existing Openstack can be divided into different areas from top to bottom: Regions (region), Availability Zones (available domain) and Host Aggregates (host collection). [0003] 1. Region is a geographical concept. Regions are completely isolated. Each Region has a complete Openstack deployment. Each Region has its own independent Service Endpoint (Service Endpoint), network and computing resources. Different Regions share a set of Keystone (authentication) and Horizon (user interface) to provide access control and Web (network) operations, so in addition to providing isolation functions, the design of Region focuses more on the concept of geographical location, and users can choose to leave their own The clo...
