For example, cloud computing environments use KVM virtualization technology. Facilities as a service, Infrastructure as a Service layer adopts traditional virtualization architecture scheme. In order to ensure the stability and high availability of the system, the current application high availability rules are as follows:

1. The original application high availability rules

1. The number of instances of core subsystems (A, B1) is not less than 3, and the number of instances of non-core subsystems is not less than 2;

2. For a subsystem, the number of instances of a single DCN is deployed on at least two different cabinets.

2. Application high-availability rules under multiple centers and multiple activities in the same city

1. The number of IDC (Internet Data Center, Internet Data Center) deployed in an instance of a subsystem is not less than 2;

2. Important subsystems (type A, B1, B2), the number of instances in a single DCN (Data Center Node, data center node) is not less than 2;

3. Important subsystems (Class A, B1, B2). The number of instances in a single DCN is deployed in at least two different cabinets.

The host resource allocation in the existing solution includes the allocation of physical hosts and virtual hosts. First, according to the needs of the resource demander, unallocated machines are screened from the CMDB according to the physical area, and a series of operations such as physical machine deployment, mother machine placement, and virtualization are performed. A resource pool is formed, and resources that meet the above two high-availability rules are manually selected from the resource pool. Finally, information such as DCN and application domains is allocated according to the subsystem and delivered to the resource demander.

With the rapid expansion of business, the scale of data centers has gradually expanded, and business application resource requirements have become more frequent. The number of scenarios that require rapid addition or replacement of nodes, such as new project launches, server migration, server out-of-guarantee, and hardware failure, has gradually increased. In resource allocation, there are more manual interventions in the whole process from resource application to resource allocation. Therefore, the delivery process of resource allocation is slow. Moreover, when manual intervention, personnel have no macro understanding of resource utilization, which may lead to resource utilization Imbalance increases the security risks of stable operation of applications. Such security risks can lead to low security of banking services (loan business, deposit business or other financial services), which does not meet the regulatory requirements of banks and other financial institutions.

If personnel are not required to participate in the process from resource application to resource allocation and fully automated, it will improve the process of resource allocation. It should be noted that the application scenarios described in the embodiments of the present invention are to illustrate the technical solutions of the embodiments of the present invention more clearly, and do not constitute a limitation on the technical solutions provided by the embodiments of the present invention. Those of ordinary skill in the art will know that With the emergence of new application scenarios, the technical solutions provided by the embodiments of the present invention are equally applicable to similar technical problems.

In view of the foregoing application scenarios, an embodiment of the present invention provides a resource allocation method. As shown in FIG. 1, the method specifically includes the following steps:

S100, determine the number of resources needed;

S101: If the number of required resources is not greater than the number of available rack groups established based on the data center wiring method TOR, select available resources with the same number of required resources from the available rack groups for allocation , Wherein the available rack group is a rack group with available resources in the rack group.

In the embodiment of the present invention, the number of required resources is first determined. If it is determined that the number of required resources is not greater than the number of available rack groups established based on TOR, then the available rack group with the same number of required resources is selected from the available rack group. Resources are allocated. The available rack group here refers to the rack group with available resources in the rack group. When it is determined that the number of resources required is not greater than the number of available rack groups, select the rack group and Resources with the same number of required resources are allocated, so that there is no need to manually select available resources in the resource pool, which improves the process of resource allocation and saves time.

When the resource demander needs resources, a resource request message will be issued. The resource request message will carry the required resources and the number of required resources, such as DCN, Appdomain, SystemId, Image, physical zone, machine model, number of instances, etc. , And then determine the required resources and the number of required resources from the resource request information.

Among them, the physical area refers to the divided physical area, such as the management area, the external area, the server group area, etc.; the machine model can be created according to the needs of the business, and the corresponding resources can be created according to the needs of the business. Corresponding requirements.

It should be noted that the resources here may be physical host resources, virtual host resources, or a combination of physical host resources and virtual host resources.

For example, the resource demander A issues a resource request message, and the resource determined in the resource request message is 5 physical host resources and 3 virtual host resources.

After determining the number of required resources, compare the number of required resources with the number of available rack groups established based on TOR. If the number of required resources is not greater than the number of available rack groups, select and Available resources with the same number of required resources are allocated, and the available rack group here is a rack group with available resources in the rack group.

The number of required resources here is the same as the number of subsequent instances, and both represent the number of resources required by the resource demander.

It should be noted that two racks form a rack group. The conventional rack is 42U and has 21 seats. The conventional physical host is 2U, so a rack can hold up to 21 physical hosts and one rack group. There can be up to 42 physical hosts.

If the physical host is occupied, the physical host can no longer be allocated. If there are 42 physical hosts in a rack group and at least one physical host is not occupied, it means that the rack group is an available rack group.

When comparing the number of required resources with the number of available rack groups, if the number of required resources is not greater than the number of available rack groups based on TOR, select the same number of resources from the available rack groups The available resources are allocated. The following describes the required resources as physical host resources and the required resources as virtual host resources.

Case 1: The required resources are physical host resources.

First, select an available rack group with a small resource usage rate from the available rack groups with the same amount of resources as needed, and then select an available rack group with a small resource usage rate from the available rack group with a small resource usage rate An available physical machine SN and IP address, and finally the selected available physical machine SN and IP address are sent to the user's terminal.

Among them, the resource usage rate of the available rack group, that is, the ratio of the number of unoccupied physical hosts under the rack group to the total number of physical hosts, and the result is the resource usage rate of the available rack group.

For example, if there are 42 physical hosts in rack group 1, 21 of which are occupied, the resource utilization rate of rack group 1 is 50%.

Select an available rack group with a small resource usage rate from the available rack groups that has the same number of resources as needed. You can calculate the resource usage rate of all available rack groups, and then select from all rack groups the same number of resources as required Available rack groups with small resource usage.

For example, there are 5 available rack groups, which are available rack group 1, available rack group 2, available rack group 3, available rack group 4, available rack group 5, and calculate each available rack separately The resource usage rate of the group, the resource usage rate of available rack group 1 is 10%, the resource usage rate of available rack group 2 is 15%, the resource usage rate of available rack group 3 is 30%, and the resource usage rate of available rack group 4 The resource utilization rate of the available rack group 5 is 35%, the resource utilization rate of the available rack group 5 is 50, and the number of resources required is 2, then select 2 available rack groups with low resource utilization from the 5 available rack groups, namely Available rack group 1 and available rack group 2.

After selecting an available rack group with a small resource usage rate that is the same as the required number of resources, for an available rack group with a small resource usage rate, select an available physical machine SN from the available rack group with a small resource usage rate And IP address.

Select an available physical machine SN and IP address from a group of available racks with a low resource utilization rate. The selection method can be random selection or selection through preset rules. This application is not limited.

For example, two available rack groups with low resource usage are selected, available rack group 1 and available rack group 2, and available rack group 1 has 2 unoccupied physical hosts, physical host 1 and physical host 2. There are 3 unoccupied physical hosts in the available rack group 2, physical host 3, physical host 4 and physical host 5. Choose an available physical host SN and IP address from each selected available rack group, The selection method can be selected randomly or according to preset rules.

After selecting the physical host SN and IP address, the selected physical host SN and IP address are returned to the terminal where the user is located.

Case 2: The required resources are virtual host resources.

Select an available rack group with the same amount of resources as the required resource from the available rack group, select an IP address with the same number of resources as the required resource from the available rack group with a small resource usage, and use the resource Select the resource name from the available rack group with low rate, determine the parent machine SN and virtual host IP address corresponding to the virtual host according to the IP address and resource name; send the parent machine SN and virtual host IP address to the user's terminal.

Select an available rack group with a smaller resource usage rate that is the same as the required number of resources from the available rack groups, which is the same as in scenario 1, and will not be repeated here.

Select an IP address with the same amount of resources from the available rack group with low resource usage. Based on the rack group, you can calculate the Openstack AZ, that is, the set of unoccupied physical hosts, and then select the IP address from the virtual network segment. The IP address pool is allocated the same number of IP addresses as the required resources, and the physical host name is incrementally allocated according to the CMDB, and the allocated IP address and physical host name are returned to the user.

It should be noted that the host name creation rule can be: CN+city+IDC+number. For example, the first host name created by the rule engine is CNSZFT05010001, the second host name is CNSZFT05010002, and so on, where CN Represents China (China), SZ represents Shenzhen, FT represents a 0501 computer room, and 0001 represents the serial number.

The above is an explanation of resource allocation when the number of required resources is not greater than the number of available rack groups. If the number of required resources is greater than the number of available rack groups, it means that the rack group cannot meet the required resources. If the required resources are If it is a physical host resource, the available resources of at least one available rack group in the available rack group can be repeatedly allocated.

The following is an example to illustrate that the required resources are physical host resources.

For example, the number of physical host resources required is 4, the available rack group is available rack group 1, available rack group 2, and available rack group 3. The number of physical resources required 4 is greater than the number of available rack groups 3. At this time, you can randomly select an available physical host from the available rack group 1, randomly select an available physical host from the rack group 2, and randomly select two available physical hosts from the available rack group 3 for resource allocation. At the time, the available rack group 3 was repeatedly allocated.

If the required resource is a virtual host resource, and the number of required resources is greater than the number of available rack groups, and is not greater than the number of available physical hosts of the business system corresponding to the required resource, then from the available physical hosts of the business system The host selects the available resources that are the same as the required number of resources for allocation.

In one embodiment, the available resources with the same amount of resources as the required resources are selected from the available physical hosts of the business system for allocation, and the AZ of Openstack can be obtained based on the rack group, that is, the set of unoccupied physical hosts. Then, from the IP address pool of the virtual network segment, an IP address equal to the required number of resources is allocated, the physical host name is incrementally allocated according to the CMDB, and the allocated IP address and physical host name are sent to the terminal where the user is located.

Here, the AZ of Openstack is obtained based on the rack group, which can be defined rules created in advance when building Openstack, that is, there is a corresponding relationship between the rack group and the AZ. After the rack group is determined, the AZ can be determined according to the corresponding relationship ；

The IP address pool of the virtual network can be a virtual network segment created in advance when Openstack is built, and the virtual network segment constitutes the IP address pool of the virtual network.

If the required resources are virtual host resources, and the number of required resources is greater than the number of available rack groups, and is greater than the number of available resources in the business system corresponding to the required resources, it means that the existing resources cannot meet the required resources. Therefore, an abnormal prompt is displayed and no resource allocation is performed.

Specific examples are described below.
