Technical Field
The invention relates to the technical field of mobile communication, in particular to a cloud platform based on two places and three centers and a communication method thereof.
Background
The two-place three-center disaster recovery solution realizes multiple protection of data and services of a production center by establishing a disaster recovery center in the same city and a disaster recovery center in a different place. When a disaster occurs in the production center, the business can be quickly switched to the disaster recovery center in the same city. When the disaster occurs to the production center and the disaster recovery center in the same city, the production service can be recovered by using the data copy in the different disaster recovery center, so that the continuity of the service is ensured to the maximum extent.
The disaster recovery method is characterized in that a disaster recovery center in two places and three centers is combined with a disaster recovery center in another place, so that when a production center encounters natural disasters or artificial damages, service data can be quickly recovered through the disaster recovery center in another place, and service continuity is guaranteed.

The IT equipment is respectively deployed in the three data centers, but business requirements are to realize double activities of the same city data center and disaster recovery of a different place disaster recovery center. This puts higher demands on the independent cloud platform management nodes respectively deployed in the three data centers.

In one embodiment of the present invention,
the cloud platform comprises a secondary management node; or,
the system comprises three secondary management nodes, and each data center is correspondingly provided with one secondary management node.
In the embodiment of the invention, the three secondary management nodes form a cluster.
In the embodiment of the present invention, one of the three secondary management nodes is a primary secondary management node, and the other two are standby secondary management nodes, that is, the cluster adopts an Active-stand by mode.
The invention is described below in conjunction with the scenario embodiments.
In the related art, when a service fails, cloud platforms and IT equipment of three data centers are required to perform unified linkage operation aiming at applications. This puts higher demands on independent cloud management nodes deployed in three data centers respectively. On one hand, the multiple data centers need to be subjected to integrated linkage management, and on the other hand, the three data centers need to be correspondingly isolated to prevent mutual interference. Aiming at the use scene, the embodiment of the invention provides a novel cloud platform architecture based on two places and three centers.
In this embodiment, an architecture supporting two-level management may be set on the basis of a conventional one-level cloud platform architecture. And the primary management node performs scheduling management and resource allocation on the cloud resources based in the cloud platform. As shown in fig. 3, the IECS is a primary management node, and the IROS is a secondary management node.
Here, a layer of management nodes, i.e., a secondary management node, may be developed above the primary management node. The second-level management node does not directly manage basic cloud resources, but performs corresponding cloud resource operation management on the first-level management nodes of the three data centers so as to support the double-active function of service application across the data centers deployed in the data centers.
The secondary management node can only perform resource scheduling and allocation through the primary management node. The secondary management node can communicate with any one of the primary management nodes of the three data centers, and corresponding scheduling of the basic cloud resources of the data centers is carried out according to the requirements of service disaster tolerance.
In the 'two places and three centers' overall environment, only one secondary management node can be deployed, or three data centers can be deployed, only one secondary management node can provide services to the outside, and the other two secondary management nodes are in a 'stand by' state.
And data are synchronized among the three secondary management nodes in real time so as to prevent single point of failure.
Here, the data may be management information data, control information data, or the like.
For the primary management node:
a set of virtualization management software is deployed at each of the three data centers;
and each data center realizes the calculation, storage and management operation of network resources on the internal resources of the respective data center through the management node.
For the secondary management node:
three data centers can be respectively provided with a secondary management node, and the three secondary management nodes can form a cluster;
the cluster adopts an Active-stand by mode, only one of the clusters is a primary secondary management node all the time, and the rest of the clusters are standby secondary management nodes;
and the secondary management node manages and schedules the basic cloud resources by calling the primary management node interface, so that the resource management of the cross-data center is realized.
As shown in fig. 4, the service flow for the cloud platform mainly includes the following steps:
the method comprises the following steps: an administrator needs to perform basic cloud resource management, such as configuration, allocation, recovery, change and other operations of computing resources, storage resources and network resources, and directly accesses a primary management node to perform operation (a cloud resource basic operation and maintenance request I);
step two: if a service fails and a double-activity switching operation of the service needs to be performed, a corresponding linkage operation request needs to be performed on cloud basic resources across the data center, an administrator performs service switching operation on a second-level management node (disaster recovery management request II), and the second-level management node automatically calls a corresponding first-level management node of the data center to perform cloud resource management according to the service switching request of the administrator (cloud resource basic operation and maintenance request III);
step three: and the cloud resource based on the data center makes a corresponding response according to the request of the primary management node.
The cloud platform of the embodiment of the invention adopts a deployment scheme of two layers of management nodes, each data center of the first layer is provided with an independent cloud management node (primary management node), so that the mutual interference influence among the data centers can be prevented; the second layer realizes integrated management on the three data centers through the secondary management node, can realize multi-activity disaster recovery management among the three centers, and supports a business disaster recovery double-activity scheme among the multiple data centers.
