Description

Method and device for sharing multi-tenant resources

This application claims the priority of the Chinese Patent Application, filed on Feb. 5, 2016, the Chinese Patent Application No. 201610082020.7, the entire disclosure of which is incorporated herein In this application.

Technical field

The present invention relates to the field of computer technologies, and in particular, to a method and apparatus for multi-tenant resource sharing.

Background technique

In the era of cloud computing, a large number of computing resources are brought together to provide services for users. Users can rent computing resources from the cloud, which can enjoy the benefits of low cost, and can be secured by security and reliability. Known as a tenant, a tenant usually corresponds to an organization, such as a company, a school, and so on.

In the prior art, computing resources are divided by a CPU (Central Processing Unit) core, and all tenants obtain a CPU core through a competition mechanism, which easily leads to a large difference in CPU cores that different tenants compete for. It is possible for a tenant who competes more CPU cores to meet the needs of the tenant with fewer CPU cores, and tenants competing for fewer CPU cores need more CPU cores to meet the needs of the tenant, resulting in a CPU core. The resource allocation is unreasonable. In addition, the ability of the tenant to compete for the CPU core may change with time. For example, the tenant's network environment is better at this moment, competing for more CPU cores, and the next time the network environment changes. Poor, the CPU core used to serve the tenant may serve other tenants, resulting in an increase in the number of CPU core switches and inefficient handling of tenant demand.

Summary of the invention

The present invention provides a method and an apparatus for multi-tenant sharing resources, which are used to solve the problem that the CPU core allocation in the prior art is unreasonable and the number of CPU core switching times is increased due to the tenant acquiring the CPU core through the competition mechanism, and the tenant demand is processed. Inefficient problem.

In a first aspect, a method for multi-tenant sharing resources is provided, including:

The central processor CPU management distributor estimates the average usage rate of the tenant's CPU core; if it is determined that the average usage rate of the tenant's CPU core is less than the expected usage rate of the CPU core preset for the tenant, the tenant is The CPU core information corresponding to at least one CPU core of each of the leased CPU cores is added to a preset CPU core linked list in the storage space, and the CPU core corresponding to the CPU core information stored in the CPU core linked list is used for re Assigning; if it is determined that the average usage rate of the CPU core of the tenant is greater than the expected usage rate of the preset CPU core, assigning, to the tenant, a CPU core corresponding to at least one CPU core information in the CPU core linked list respectively The average usage rate of the CPU core is an average value of usage rates of the CPU cores rented by the tenant within a set time period, and the tenant is stored in a storage space managed by the CPU management distributor. Any tenant.

Since the CPU management allocator can estimate the average usage rate of the CPU core of the tenant within the set duration, and when the average usage rate of the tenant's CPU core is less than the expected usage rate of the CPU core preset for the tenant, The CPU core information corresponding to at least one CPU core of the CPU core leased by the tenant is added to the CPU core list for redistribution. When it is determined that the tenant needs to rent the CPU core, at least one stored CPU is selected from the CPU core list. The CPU core corresponding to the core information is assigned to the tenant, thereby passing the average use of the CPU core to the tenant within the set duration. The estimation of the rate enables the CPU management allocator management to dynamically allocate the CPU cores rented by the tenants stored in the storage space according to the estimated average usage rate of the tenants, thereby avoiding the CPU caused by the competition in the prior art. The unreasonable problem of nuclear distribution, while reducing the number of CPU core switching, thus improving the efficiency of processing tenant needs.

On the basis of the first aspect, the method further includes: when the CPU manages a new tenant added to the storage space, the new tenant is allocated in the CPU core list. At least one CPU core information corresponding to the CPU core.

When a new tenant is added to the storage space, the CPU core corresponding to at least one CPU core information in the CPU core linked list can be allocated to the new group, thereby avoiding new users competing for the CPU core through the competition mechanism, thereby avoiding In the prior art, the unreasonable problem of CPU core allocation due to competition, while reducing the number of CPU core switching, thereby improving the efficiency of processing tenant requirements.

On the basis of the first aspect, optionally, the CPU core linked list includes an idle linked list and a candidate linked list; when the average usage rate of the tenant's CPU core is less than the minimum usage rate of the CPU core preset for the tenant The CPU management allocator adds CPU core information corresponding to at least one CPU core of each CPU core rented by the tenant to the free list; when the average usage rate of the CPU core of the tenant is greater than When the minimum usage rate of the CPU core preset by the tenant is less than the expected usage rate of the CPU core preset for the tenant, the CPU management distributor allocates at least one CPU of each CPU core rented by the tenant The CPU core information corresponding to the core and the lease priority information mapping of the tenant lease CPU core are added to the candidate linked list; wherein, the expected usage rate of the tenant's CPU core is greater than the minimum usage of the tenant's CPU core rate.

Since the average usage rate of the estimated tenant's CPU core is less than the minimum usage rate of the CPU core preset for the tenant, the tenant can reduce the number of CPU cores to be rented, thus reducing the nuclear information of the leased CPU core. In the free list, when the average usage rate of the CPU core of the estimated tenant is greater than the minimum usage rate of the CPU core preset for the tenant, and less than the expected usage rate of the CPU core preset for the tenant, the tenant is explained There is a demand for the leased CPU core. When other tenants have CPU core requirements and no idle CPU core can be rented, the tenant's CPU core can be used as a candidate solution to further refine the CPU core list. The allocation of CPU cores rented by tenants is more reasonable.

On the basis of the first aspect, optionally, the CPU management allocator determines that an average usage rate of the CPU core of the tenant is greater than a maximum usage rate of a CPU core preset for the tenant, and the free list is If it is empty, the CPU core information corresponding to the at least one lease priority information selected in descending order of the lease priority information stored in the candidate linked list is selected, and the CPU core corresponding to the selected CPU core information is allocated. Giving the tenant; if it is determined that the average usage rate of the CPU core of the tenant is greater than the expected usage rate of the CPU core preset for the tenant, and the free linked list is not empty, storing the stored in the free list A CPU core corresponding to at least one CPU core information is allocated to the tenant; wherein a desired usage rate of the tenant's CPU core is less than a maximum usage rate of the tenant's CPU core.

Since the CPU management allocator further refines the scheme for allocating the CPU core by using the expected usage rate of the CPU core of the tenant and the maximum usage rate for the tenant, the allocation of the CPU core leased by the tenant is more reasonable. And the CPU core with low priority of the tenant is preferentially provided to the CPU core tenant, thereby ensuring the use of the high priority group.

On the basis of the first aspect, optionally, the CPU management allocator determines that an average usage rate of the CPU core of the tenant is greater than a expected usage rate of a CPU core preset for the tenant, and is smaller than If the maximum usage rate of the CPU core preset by the tenant is empty and the free list is empty, the CPU core is no longer allocated to the tenant.

Because the scheme further refines the scheme for allocating CPU cores, the allocation of CPU cores rented by tenants is more reasonable.

On the basis of the first aspect, optionally, if the CPU management allocator determines that the CPU core needs to be allocated for at least two tenants, the lease priority information of the CPU core is rented according to each of the at least two tenants. In the low order, each of the tenants is assigned a CPU core.

Since the CPU management allocator allocates a CPU core to a tenant with a high priority priority when it is determined that at least two CPUs are allocated to the tenant, the demand of the high priority tenant for the CPU core is ensured.

The second aspect provides an apparatus for sharing resources by a multi-tenant, including: a calculation module and a judgment module; wherein the calculation module is configured to estimate an average usage rate of the tenant's CPU core, and the average usage rate of the CPU core is An average value of usage rates of the CPU cores rented by the tenant in the set time period, the tenant is any tenant stored in the storage space managed by the CPU management splitter; the determining module is configured to determine the tenant When the average usage rate of the CPU core is less than the expected usage rate of the CPU core preset for the tenant, the CPU core information corresponding to at least one CPU core of each CPU core rented by the tenant is added to the storage. In the CPU core linked list preset in the space, the CPU core corresponding to the CPU core information stored in the CPU core linked list is used for reallocation; determining that the average usage rate of the tenant's CPU core is greater than the preset CPU core When the expected usage rate is reached, the tenant is allocated a CPU core corresponding to at least one CPU core information in the CPU core linked list.

Since the calculation module can estimate the average usage rate of the CPU core of the tenant within the set duration, and the judging module is when the average usage rate of the tenant's CPU core is less than the expected usage rate of the CPU core preset for the tenant, The CPU core information corresponding to at least one CPU core of the CPU core leased by the tenant is added to the CPU core list for redistribution. When it is determined that the tenant needs to rent the CPU core, at least one stored CPU is selected from the CPU core list. The CPU core corresponding to the core information is allocated to the tenant, so that the device can dynamically allocate the storage space according to the estimated average occupancy rate of the tenant by estimating the average usage rate of the CPU core within the set time period. The CPU cores rented by the tenants stored in the system avoid the unreasonable problem of the CPU core allocation caused by the competition in the prior art, and reduce the number of switching of the CPU cores, thereby improving the efficiency of processing the tenant requirements.

On the basis of the second aspect, optionally, the apparatus further includes: a processing module; when the processing module is configured to add a new tenant in the storage space, assign the CPU core linked list to the new tenant At least one of the CPU core information corresponds to the CPU core.

On the basis of the second aspect, optionally, the CPU core linked list includes a free linked list and a candidate linked list; and the determining module is specifically configured to: when an average usage rate of the tenant's CPU core is less than preset for the tenant When the minimum usage rate of the CPU core is used, CPU core information corresponding to at least one CPU core of each CPU core rented by the tenant is added to the free list; when the average usage rate of the CPU core of the tenant is greater than a CPU corresponding to at least one of the CPU cores rented by the tenant when the minimum usage rate of the CPU core set in advance by the tenant is smaller than the expected usage rate of the CPU core preset for the tenant The core information, and the lease priority information map of the tenant lease CPU core are added to the candidate list; wherein the expected usage rate of the tenant's CPU core is greater than the minimum usage rate of the tenant's CPU core.

Because the average usage of the CPU core of the estimated tenant is less than the minimum of the CPU core preset for the tenant. When the usage rate is used, the tenant can reduce the number of CPU cores leased, so the core information of the leased CPU core is added to the free list, and the average usage of the CPU core of the estimated tenant is greater than the preset for the tenant. When the minimum usage rate of the CPU core is less than the expected usage rate of the CPU core preset for the tenant, the tenant has a demand for the rented CPU core, and the other CPU has a CPU core requirement and no free CPU core. When the lease is available, the tenant's CPU core can be used as a candidate solution. By refining the CPU core linked list, the allocation of the CPU cores rented by the tenants is further rationalized.

On the basis of the second aspect, the determining module is specifically configured to: if it is determined that an average usage rate of the CPU core of the tenant is greater than a maximum usage rate of a CPU core preset for the tenant, and If the free list is empty, the CPU core information corresponding to the at least one lease priority information selected in descending order of the lease priority information stored in the candidate linked list is selected, and the CPU corresponding to the selected CPU core information is selected. The core is allocated to the tenant; if it is determined that the average usage rate of the CPU core of the tenant is greater than the expected usage rate of the CPU core preset for the tenant, and the free linked list is not empty, then the idle linked list is A CPU core corresponding to the stored at least one CPU core information is allocated to the tenant; wherein a desired usage rate of the tenant's CPU core is less than a maximum usage rate of the tenant's CPU core.

Since the scheme for allocating the CPU core is further refined by the expected usage rate of the CPU core for the tenant and the maximum usage rate for the tenant, the allocation of the CPU core leased by the tenant is more reasonable, and the tenant is preferentially prioritized. A CPU with a lower priority is provided to the CPU core tenant, thus ensuring the use of high priority groups.

On the basis of the second aspect, optionally, the determining module is further configured to: if it is determined that an average usage rate of the CPU core of the tenant is greater than a expected usage rate of a CPU core preset for the tenant, and less than If the tenant has a maximum usage rate of the CPU core set in advance, and the free linked list is empty, the CPU core is no longer allocated to the tenant.

On the basis of the second aspect, the determining module is further configured to: if it is determined that the CPU core needs to be allocated to at least two tenants, renting the CPU core's lease priority information according to each of the at least two tenants. From the highest to the lowest order, each of the tenants is assigned a CPU core.

detailed description

In order to make the objects, technical solutions, and advantages of the present invention more comprehensible, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

In order to enable each tenant to rent from the cloud to the CPU core to meet the needs of the tenant, the solution exists in the prior art. The method of the multi-tenant sharing resources is provided by the embodiment of the present invention.

FIG. 1 is a schematic diagram of a system architecture of a multi-tenant shared resource according to an embodiment of the present invention. The system architecture includes: a server, and a plurality of terminal devices, where the server includes a CPU management allocator and a plurality of CPU cores, where The tenant sends a request to the server through the APP (Application) in the terminal device. The server allocates a CPU core to the tenant through the CPU management allocator, and performs a request of the tenant. The CPU management allocator records the tenant through the storage space managed by the CPU management allocator. Relevant information, including but not limited to the tenant's own information, such as priority, name, etc., the tenant uses the CPU core usage record.

According to the technical solution provided by the embodiment of the present invention, the CPU management allocator can dynamically allocate the CPU core to the stored tenants in the storage space managed by the CPU management agent according to the estimated average usage rate of the tenant CPU core, thereby The irrational problem of the CPU core allocation caused by the competition in the prior art is avoided, and the number of switching of the CPU core is reduced, thereby improving the efficiency of processing the tenant demand.

The technical solutions provided by the embodiments of the present invention are described in detail below.

As shown in FIG. 2, a method for a multi-tenant to share resources according to an embodiment of the present invention includes:

In step 200, the CPU management allocator estimates the average usage rate of the tenant's CPU core. The average usage rate of the CPU core is the average value of the usage rate of each CPU core rented by the tenant within the set time period, and the tenant is the CPU management allocator. Any tenant that has been stored in the managed storage space;

Step 201: The CPU management distributor determines that the average usage rate of the tenant's CPU core is less than the expected usage rate of the CPU core preset for the tenant, and the CPU core information corresponding to at least one CPU core of each CPU core rented by the tenant. Add to the preset CPU core linked list in the storage space, and the CPU core corresponding to the CPU core information stored in the CPU core linked list is used for reallocation;

Step 202: The CPU management allocator determines, for the tenant, a CPU core corresponding to at least one CPU core information in the CPU core linked list, if it is determined that the average usage rate of the tenant's CPU core is greater than a preset usage rate of the CPU core.

It should be noted that, in step 200, the set duration is a period of time after the CPU management allocator estimates the average usage rate of the CPU core of the first tenant, that is, the average usage rate of the CPU core of the tenant estimated by the CPU management allocator. The average usage rate of the CPU core of the tenant for a period of time in the future.

Specifically, the CPU management allocator predicts or estimates the average usage rate of the CPU core of the tenant in the set duration by counting the tenant CPU core running data.

Optionally, the CPU management allocator periodically estimates the average usage rate of the CPU core of the first tenant. Specifically, the CPU management allocator estimates the average usage rate of the CPU core of the first tenant in the period at the beginning of each period.

In step 201, when the CPU management allocator determines that the average usage rate of the tenant's CPU core is less than the expected usage rate of the CPU core preset for the first tenant, the first tenant rents the CPU core according to a preset algorithm. The number of CPU cores that can be used for reallocation, and adds a corresponding number of CPU core information to the CPU core list.

If the CPU core linked list includes a free linked list and a candidate linked list, optionally, when the average usage rate of the tenant's CPU core is less than the minimum usage rate of the CPU core preset for the tenant, the CPU management allocator rents the tenant. The CPU core information corresponding to at least one CPU core of each CPU core is added to the idle linked list; when the average usage rate of the tenant's CPU core is greater than the minimum usage rate of the CPU core preset for the tenant, and less than for the tenant When the expected usage rate of the CPU core is set, the CPU management allocator adds the CPU core information corresponding to at least one CPU core of each CPU core rented by the tenant, and the lease priority information mapping of the tenant leased CPU core to the candidate. In the linked list; wherein the expected usage rate of the tenant's CPU core is greater than the minimum usage rate of the tenant's CPU core.

Taking tenant 1 as an example, the expected usage rate of the CPU core preset for tenant 1 is 70%, and the minimum usage rate of the CPU core preset for tenant 1 is 50%:

Scenario 1: If the average usage rate of the CPU core of the tenant 1 estimated by the CPU management allocator is 40%, since the average usage rate of the CPU core is smaller than the minimum usage rate of the CPU core preset for the tenant 1, according to the preset The algorithm determines that the number of released CPU cores is 1, and adds the corresponding number of cores of the CPU core to the free list. Specifically, the step of determining the number of released CPU cores is as follows:

The number of CPU cores that tenant 1 needs to lease during the set duration is n=40%/50%*N. When N=4, n=3.2, rounding down, the CPU needs to be rented in the set duration. The number of cores is four, where N is the expected number of CPU cores that are preset for the tenant 1. If the number of CPU cores rented by the current tenant 1 is five, the number of CPU cores that can be released is one.

The CPU core corresponding to the CPU core information stored in the free list indicates that the tenant no longer uses the CPU core, and the CPU core is in an idle state.

It should be noted that the algorithm for determining the number of released CPU cores is not limited to the above algorithm, and other algorithms that can be used to determine the number of released CPU cores may be used.

Scenario 2: If the average usage rate of the CPU core of the tenant estimated by the CPU management allocator is 60%, since the average usage rate of the CPU core is greater than the minimum usage rate and less than the expected usage rate, it is determined according to a preset algorithm. The number of CPU cores to be reassigned, and the core information of the corresponding number of CPU cores and the priority information mapping of the tenant-learned CPU cores are added to the candidate list.

The CPU core corresponding to the CPU core information stored in the candidate linked list is the CPU core currently used by the tenant. When there is a tenant that needs to apply for the CPU core, the CPU core can be allocated to the tenant who needs to apply for the CPU core.

In step 202, when it is determined that the average usage rate of the CPU core of the tenant is greater than the expected usage rate of the CPU core preset for the tenant, further determining the number of the CPU cores that the tenant needs to apply for renting according to a preset algorithm.

Specifically, when the average usage rate of the tenant's CPU core is greater than the expected usage rate of the CPU core preset for the tenant and less than the maximum usage rate of the CPU core preset for the tenant, and the free list is not empty, then The determined number of CPU cores allocated to the tenant is a CPU core corresponding to at least one CPU core information stored in the idle linked list, wherein the maximum usage rate of the CPU core preset for the tenant is greater than the CPU core preset for the tenant. Expected usage.

When the average usage rate of the tenant's CPU core is greater than the expected usage rate of the CPU core preset for the tenant, and is less than the maximum usage rate of the CPU core preset for the tenant, and the free list is empty, it is no longer the first The second tenant allocates the CPU core.

When the average usage rate of the tenant's CPU core is greater than the maximum usage rate of the CPU core preset for the tenant, and the free list is not empty, the determined number of CPU cores allocated to the tenant is the CPU stored in the free list. The core information corresponds to the CPU core.

When the average usage rate of the tenant's CPU core is greater than the maximum usage rate of the CPU core preset for the tenant, and the free list is empty, the determined number of CPU cores allocated to the tenant is the CPU core stored in the candidate linked list. The CPU core corresponding to the information.

It should be noted that, when the CPU management allocator determines that the CPU core needs to be allocated for at least two tenants, the lease priority information of each of the at least two tenants renting the CPU core is in descending order, respectively. Each tenant allocates a CPU core.

In addition, when a new tenant is added to the storage space managed by the CPU management allocator, the CPU management allocator is The new tenant allocates a CPU core corresponding to at least one CPU core information in the CPU core linked list.

Optionally, when a new tenant is added to the storage space managed by the CPU management allocator, if the CPU management allocator determines that the free linked list is not empty, the new tenant is allocated with at least one CPU core information in the free linked list. The CPU core is configured to allocate a CPU core corresponding to at least one CPU core information in the candidate linked list to the new tenant, so as to ensure that the new tenant can be allocated to the usable CPU core.

The tenant information is stored in the storage space managed by the CPU management allocator. As shown in FIG. 3, the method for sharing resources by the multi-tenant according to the embodiment of the present invention includes:

Step 300: The CPU management allocator determines the order of priority of the tenant to rent the CPU in the storage space according to the priority information of the tenant renting the CPU core.

The CPU management allocator determines the CPU core information in the free list and the candidate list that can be used for reallocation, and performs the following steps in sequence according to the order of priority of the tenant to rent the CPU:

Step 301: The CPU management allocator estimates an average usage rate of the CPU core of the tenant stored in the storage space, and the average usage rate of the CPU core is an average of the usage rates of the CPU cores rented by the tenant within the set duration. value.

Step 302, the CPU management allocator determines whether the average usage rate of the tenant's CPU core is less than the minimum usage rate of the CPU core preset for the tenant, and if so, step 304 is performed, otherwise step 303 is performed;

Step 303, the CPU management allocator determines whether the average usage rate of the tenant's CPU core is less than the expected usage rate of the CPU core preset for the tenant, and if so, step 305 is performed, otherwise step 306 is performed;

Step 304: The CPU management allocator determines the number of CPU cores that can be released in the CPU core rented by the tenant, and adds a corresponding number of CPU core information that can be released to the idle linked list, and the CPU core information saved in the idle linked list The corresponding CPU core is used for reallocation, and step 306 is performed.

Step 305: The CPU management allocator determines the number of CPU cores that can be used for reallocation in the CPU core rented by the tenant, and uses the corresponding number of CPU core information that can be used for reallocation and the priority of the tenant to lease the CPU core. The mapping of the level information is added to the candidate linked list, and the CPU core corresponding to the CPU core information saved in the candidate linked list is used for reallocation, and step 306 is performed.

Step 306: The CPU management allocator determines whether there is still a tenant in the storage space that needs to estimate the average usage rate of the CPU core in the set time period. If yes, the current tenant is switched to the next tenant adjacent to the current tenant priority information, and then Go to step 301, otherwise go to step 307;

The CPU management allocator sequentially executes according to the priority order of the CPU cores that are greater than the expected usage rate of the pre-set CPU cores.

Step 307: The CPU management allocator determines the number of CPU cores that the tenant needs to apply for lease when determining that the average usage rate of the tenant's CPU core is greater than the expected usage rate preset for the tenant;

Step 308, the CPU management allocator determines that the average usage rate of the tenant's CPU core is greater than the maximum usage rate of the CPU core preset for the tenant, and the free linked list is not empty, then selects the CPU that needs to be applied from the free list. The core information is allocated to the tenant corresponding to the selected CPU core information.

Step 309, if the CPU management allocator determines that the average usage rate of the tenant's CPU core is greater than the maximum usage rate of the CPU core preset for the tenant, and the free linked list is empty, the CPU core priority is rented from the candidate linked list according to the tenant. In the low-to-high order, select the CPU core information that needs to be applied, and assign the CPU core corresponding to the selected CPU core information to the tenant.

Step 310: The CPU management allocator determines that the average usage rate of the tenant's CPU core is greater than the expected usage rate of the CPU core preset for the tenant, less than the maximum usage rate of the CPU core preset for the tenant, and the idle chain. If the table is empty, the tenant is no longer assigned a CPU core.

Step 311: The CPU management allocator determines that the average usage rate of the tenant's CPU core is greater than the expected usage rate of the CPU core preset for the tenant, less than the maximum usage rate of the CPU core preset for the tenant, and the free list is not If it is empty, the CPU core information that needs to be applied is selected from the free list, and the CPU core corresponding to the selected CPU core information is allocated to the tenant for use.
