Description

A resource allocation method, device and equipment

technical field

The present invention relates to the technical field of resource allocation, in particular to a resource allocation method, device and equipment.

Background technique

With the promotion of the cloud concept, the layered architecture of business application layer and management layer is widely used in solutions that require dynamic allocation of resources.

Business applications send business resource requests to the infrastructure management system to apply for the infrastructure resources needed to process specific businesses to run their instances. The resource specifications requested in the service resource requests sent by the infrastructure management system for business applications (resource specifications can be physical specifications such as CPU, memory, and network connections, or other quality attribute requirements), and the distribution of resources available in the system situation, conduct a comprehensive analysis and allocate resources.

At present, when the infrastructure management system allocates resources, under the premise of meeting the resource specifications, it first selects the enabled infrastructure resource entities for resource allocation, and tries not to use unenabled infrastructure resource entities. Among the entities, the infrastructure resource entity with the least remaining resources is preferentially selected for resource allocation, and the resources are released after the resource occupation time of the business application reaches.

The above process of resource allocation can improve resource utilization to a certain extent. However, different business applications occupy resources at different times. For example, the resource (1/2) on infrastructure resource entity 1 in Figure 1 is is released, but the resource (1/4) on the infrastructure resource entity 1 and the resource (1/2) on the infrastructure resource entity 2 need to be occupied for a long time, although the resource (1/4) occupies the resources of the infrastructure resource entity Less, but still needs to run the infrastructure resource entity 1, so the infrastructure resource entity 1 and the infrastructure resource entity 2 need to be run at the same time, the resource utilization rate in the infrastructure management system is difficult to maintain an optimized state for a long time.

A: Make sure that the infrastructure resource entity is enabled in the set resource collection.

The set resource set in the embodiment of the present invention may be all resources in the infrastructure management system, or may be some resources in the infrastructure management system.

In the embodiment of the present invention, it is preferable to set some resources in the infrastructure management system, and perform resource allocation based on life cycle attribute information, so that the infrastructure management system can simultaneously support the original allocation mechanism externally (that is, the life cycle of resource occupation is not considered). ), and a mechanism for resource allocation based on lifecycle information. Moreover, in the embodiment of the present invention, some resources are set to perform resource allocation based on life cycle information, which can avoid the influence of uncertainty of the original resource allocation mechanism on resource allocation based on life cycle attribute information.

In the embodiment of the present invention, the implementation method of the resource allocation method will be described in detail below.

The execution subject of the method shown in Figure 4 may be, for example, an infrastructure management system, or a component of the infrastructure management system, and the embodiment of the present invention does not limited. As shown in Figure 4, the method includes:

S101: Obtain lifecycle attribute information of a service application.

In the embodiment of the present invention, the life cycle attribute information reflects the time information that the service application is expected to occupy resources.

In the embodiment of the present invention, the scalable resource request interface has the function of carrying the service application life cycle attribute information, and obtains the service application life cycle attribute information by calling the service resource request interface to carry the service application life cycle attribute information function.

The life cycle attribute information in the embodiment of the present invention can be represented by the structure shown in Table 1 below, for example,

Table 1

It should be noted that the lifecycle attribute information in the embodiment of the present invention is not limited to the examples listed in Table 1, but should also include any manner that can be used to describe the time when the resource is expected to be occupied. For example, a time list may also be used to list expected irregular (non-repetitive cycle) usage times.

S102: Based on the life cycle attribute information, determine a reserved resource that can optimize resource utilization within a predictable subsequent time, and reserve the determined reserved resource for the business application.

In the embodiment of the present invention, the reserved resources are reserved for business applications. The reserved reserved resources are not actually allocated and occupied, but the reserved resources can no longer be reserved or allocated to other than the currently reserved resources within the reserved time. Business applications other than business applications.

In the embodiment of the present invention, based on the life cycle attribute information to determine the resource reservation process that can optimize the resource utilization rate within the expected period of time, it can be used to reduce resource fragmentation, enable the minimum number of infrastructure resource entities, and stay in the optimized state for a long time At least one of the optimization objectives is used to determine reserved resources.

For example, in the embodiment of the present invention, based on the life cycle attribute information, the process of determining the reservation resource that can optimize the resource utilization rate within the expected subsequent time may be as follows:

Determine the enabled infrastructure resource entities in the set resource collection, and determine the expected resource occupancy time of the allocated resources and reserved resources on the enabled infrastructure resource entities.

Preferentially select the resources on the enabled infrastructure resource entity whose resource occupation time is close to the expected resource occupation time in the life cycle attribute information in the subsequent predictable time, and whose unallocated resources meet the resource conditions required by the business application, as the reservation resource.

S103: Allocate reserved resources to the service application when the start time of resource occupation expected by the service application is reached.

The resource allocation method provided by the embodiment of the present invention obtains the life cycle attribute information of the business application, and the life cycle attribute information can reflect the time information that the business application is expected to occupy the resources, so the resource occupation time in the subsequent predictable time can be known in advance . Then, based on the acquired life cycle attribute information, determine the reserved resources that can optimize the utilization rate of resources within the expected period of time, reserve the reserved resources for the business application, and when the start time of the expected occupation of resources by the business application is reached, the reserved resources Assigned to business applications, the resource utilization in the infrastructure management system can be optimized within a predictable time and maintain an optimized state.

In the embodiment of the present invention, based on the life cycle attribute information of the business application, the reserved resources for resource reservation for the business application are not actually allocated and occupied. Therefore, in the embodiment of the present invention, by changing the reservation information, another basic The resources of the facility resource entity are reserved for business applications without involving any resource migration technology, and the technical implementation is simple and easy.

Optionally, in the embodiment of the present invention, in order to further ensure that the resources in the infrastructure management system are in an optimized state for a long time, that is, on the premise that the resource utilization rate meets further optimization conditions, the reserved resources can be re-reserved, wherein the further optimization The condition may be, for example, that resource fragmentation can be reduced, the number of enabled infrastructure resource entities can be minimized, or the infrastructure resource entities in the infrastructure management system can be in an optimized state for a long time.

For example, in the embodiment of the present invention, the resource occupancy time of the resources reserved on the current infrastructure resource entity can be expected to be close to the time when the current business application is expected to occupy resources, and the unallocated resources of the current infrastructure resource entity do not meet the current requirements. In the case of resources required by business applications, re-reserve the reserved resources on the current infrastructure resource entity, and allocate the reserved resources and the resources required by the current application to the same infrastructure resource entity to optimize resource utilization.

The embodiments of the present invention will hereinafter describe the above resource allocation process in detail in combination with practical applications.

In the embodiment of the present invention, it is assumed that the resource specifications of the infrastructure resource entities in the infrastructure management system are the same, the total amount of resources is denoted as 1S, and the resources corresponding to the three infrastructure resource entities are respectively Sn, where n=1, 2 and 3. The resource specifications for business application applications are 0.25S, 0.5S or 0.75S (resource specifications are multi-dimensional in reality). Assuming that the infrastructure management system needs to process 5 resource requests rX in sequence (X=A, B, C, D, E), the requested resource specifications and timing relationships are shown in Figure 5A and Figure 5B, where two adjacent time points The interval between is time T, and the resources corresponding to rA and rD are released after a period of use, while rB, rC and rE continue to be occupied for a long time.

FIG. 5A is a schematic diagram of resource allocation according to the original allocation mechanism that does not consider life cycle attribute information, and FIG. 5B is a schematic diagram of resource allocation based on life cycle attribute information according to an embodiment of the present invention.

In Fig. 5A, when it is impossible to predict the resource occupation time in the subsequent predictable time, resources are allocated from the infrastructure resource entities that have been allocated some resources according to the priority, that is, new infrastructure resource entities are used as much as possible, And when the above conditions are met, the infrastructure resource entities with the least remaining resources and the least allocated business resources are preferentially selected for resource allocation. The function of this point is to avoid "fragmentation" of resources and improve resource utilization. According to the determination method of resource utilization ratio=actually allocated total resources/the total resources of enabled infrastructure resource entities, a simple calculation can obtain that the overall resource utilization ratio during t1-t6 is only about 56%. After t6 if the distribution situation does not change, the utilization rate will remain at a low level of about 33% for a long time.

In FIG. 5B, the process of resource allocation based on life cycle attribute information provided by the embodiment of the present invention is as follows:

A: Before t1, rA and rC made resource reservations in advance. Although the expected resource occupation time of the two was very different, there were no other resource distributions for optimal allocation at that time, so they were all reserved to s1 (resources were not allocated). The real allocation is occupied, and it is still in the power-off state).

B: At t1, rA allocates resources according to the original reservation, and s1 is powered on. When dealing with rB, the system analyzes that rB and rC are expected to occupy resources for a long time in the future, which is basically the same, and allocating them together can bring long-term resource optimization effects. Therefore, start s2 to allocate rB resources, and reschedule rC to s2.

C: rE is processed at t4, and s3 should be used for allocation according to the general strategy without considering the life cycle attribute information. However, since rE and rB, that is, rC, are expected to occupy resources in the subsequent predictable time, they are basically the same (both run for a long time), so the allocation strategy is adjusted appropriately and designated to be allocated by s2.

Through the above-mentioned resource allocation method, according to the calculation method of the aforementioned resource utilization rate, the result of adopting the method of the present invention in this example is that, within the time t1～t6, the resource utilization rate is 67.5% (originally 56%); Long-running resource utilization is 100%.

The resource allocation method provided by the embodiment of the present invention obtains the life cycle attribute information of the business application, and the life cycle attribute information can reflect the time information that the business application is expected to occupy the resources, so the resource occupation time in the subsequent predictable time can be known in advance . Then, based on the acquired life cycle attribute information, determine the reserved resources that can optimize the utilization rate of resources within the expected period of time, reserve the reserved resources for the business application, and when the start time of the expected occupation of resources by the business application is reached, the reserved resources Assigned to business applications, the resource utilization in the infrastructure management system can be optimized within a predictable time and maintain an optimized state. Furthermore, in the embodiment of the present invention, simple risk-free "rebooking" adjustments can be performed when necessary, so that the use of overall resources can be kept in an optimized state for a predictable period of time, and the technical implementation is simple.

It should be noted that the resources on the infrastructure resource entity in the infrastructure management system in the embodiment of the present invention may be the resources used by the upper-layer business applications managed by the infrastructure management system or a combination thereof, such as network resources (network connections and Communication bandwidth, etc.), storage resources, certain types of special processing capabilities (such as data encryption and decryption processing capabilities provided by special hardware), etc. Moreover, there are various forms of resource allocation. For example, computing resources are taken as an example (other types of resources are similar), and the form of allocated resources is not limited to virtual machines using virtualization technology, but can also include any part of physical resources or The form provided to applicants as a whole, such as the CGroups technology provided by the Linux kernel, can divide a resource under the management of an OS (usually a physical server) into multiple entities containing certain resources. Furthermore, infrastructure resource entities are also diverse. Taking computing resources as an example (similar to other types of resources), the scope of the physical resource entity does not necessarily refer to a physical server, but can be any server that can provide a certain amount of computing resources. A physical or logical collection of . For example, it may be several blade servers in a chassis, servers in a computer room, or servers logically divided into a cluster, and so on.

Furthermore, based on the resource allocation method provided above in the embodiment of the present invention, the method of resource allocation based on life cycle attribute information can be flexibly applied to the current infrastructure according to the actual situation

management system, such as:

A: Life cycle attribute information is a mandatory attribute

For example, in some enterprises or internal infrastructure management systems of departments, in order to maximize the effect of the method of the present invention, its users (such as personnel in the department) may be required to provide their corresponding estimated life cycle information when submitting a resource application .

For example, in some enterprises or internal infrastructure management systems of departments, in order to obtain the effect of the method of the present invention to the greatest extent, resources will be allocated strictly according to the life cycle specified by its users (such as personnel in the department) when submitting resource applications, that is, Users cannot access and use the resource at times outside the pre-specified lifetime range. Of course, this way needs to be notified to the user in advance of the constraint condition by means such as a specification.

B: Life cycle attribute information as an optional attribute

The resource allocation method based on the life cycle attribute information provided by the embodiment of the present invention can only be applied to some infrastructure resource management entities in the infrastructure management system, and the original resource allocation method can be applied to the rest. A typical example may be that the infrastructure management system can support resource requests with or without life cycle information externally, but internally distinguishes the two types of requests, and uses the method of the present invention for requests that carry life cycle information Perform resource allocation and optimization, and specify a dedicated resource set for it; the remaining requests continue to use the original allocation mechanism (that is, regardless of the life cycle of resource occupation), and specify another resource set to undertake resource allocation. The advantage of distinguishing between the two is that the resource allocation of the former is analyzed and optimized based on the resource life cycle, which avoids the influence of the uncertainty of resource allocation and use of the latter (regardless of the life cycle of resource occupation) on the effect of the former. .
