Embodiments of the present application will be described below with reference to the accompanying drawings.
The resource allocation method provided by the application can be applied to the application environment shown in fig. 1. Specifically, the number of the clients may be multiple, and the embodiment of the present application is illustrated by 2 examples, and includes a client 101a and a client 101b, where the client 101a and the client 101b lease resources of a server. The server 102 includes a first resource pool, where the first resource pool includes fixed resources and mobile resources, and the fixed resources and the mobile resources are allocated according to a preset proportion. When the client applies for the resource of the leased server 102, the client can apply for a fixed resource and a mobile resource at the same time, the fixed resource is fixed for the corresponding client to use, and when the fixed resource corresponding to the client is not enough for the client to use, the mobile resource is allocated to the client to use. Specifically, for example, when the client 101a needs to expand the capacity of the resource during the peak period of the service of the client 101a, the client 101a sends a resource capacity expansion instruction to the server 102, and the server 102 receives the resource capacity expansion instruction sent by the client 101a, where the resource capacity expansion instruction includes the capacity expansion resource amount; when the capacity expansion resource amount is larger than the sum of the fixed resource remaining amount corresponding to the client 101a and the flow resource remaining amount corresponding to the client 101a, sending a capacity expansion failure instruction to the client; and when the capacity expansion resource amount is larger than the fixed resource residual amount corresponding to the client 101a and is smaller than the sum of the fixed resource residual amount corresponding to the client 101a and the mobile resource residual amount corresponding to the client 101a, allocating the mobile resource of the first resource pool to the client 101 a.
Those skilled in the art will appreciate that the client 101a, the client 101b and the server 102 may be terminals to execute corresponding programs. In other embodiments, the client 101a, the client 101b and the server 102 may be replaced by servers.
Those skilled in the art will understand that the "terminal" used herein may be a Mobile phone, a tablet computer, a PDA (Personal Digital Assistant), an MID (Mobile Internet Device), etc.; a "server" may be implemented as a stand-alone server or as a server cluster comprised of multiple servers.
Referring to fig. 2, an embodiment of the present application provides a resource allocation method, which can be applied to the server side, where the server side includes a first resource pool, and the first resource pool includes fixed resources and mobile resources, and the method includes:
s201: and receiving a resource capacity expansion instruction sent by the client, wherein the resource capacity expansion instruction comprises capacity expansion resource quantity.
The client side is in communication connection with the server side. The client leases the resources in the first resource library of the server to meet the business needs of the client. The first resource pool may be a resource of a Platform As A Service (PAAS).
The fixed resources are fixedly allocated to the client and cannot increase or decrease along with the change of time; the mobile resource is the resource which is allocated to the client to use when the client needs. In the first resource library, the fixed resources and the mobile resources are allocated according to a preset proportion, the preset proportion is not limited, for example, the proportion of the fixed resources to the mobile resources is 8:2 or 7:3, and the preset proportion can be set or changed according to requirements. The client applies for renting the resources in the first resource library of the server in advance, and the client can apply for the fixed resources or apply for the fixed resources and the mobile resources simultaneously. For example, if the resources required by the client at ordinary times are 7G or less, and the client at a peak of service period requires 9G, the client may apply for the fixed resources 7G and the mobile resources 2G, or the client applies for the fixed resources 8G and the mobile resources 2G.
During the service peak period of the client, the service demand is increased, and when the resource expansion is needed, the client sends a resource expansion instruction to the server, wherein the resource expansion instruction includes an expansion resource amount, and the expansion resource amount is the resource amount needed to be increased when the client expands the capacity. The server can receive a resource capacity expansion instruction sent by the client.
S202: and when the capacity expansion resource amount is larger than the sum of the fixed resource surplus corresponding to the client and the flowing resource surplus corresponding to the client, sending a capacity expansion failure instruction to the client.
When the client has expanded capacity, the client may have used some of the resources. For example, the fixed resource applied by the client includes 8G, the mobile resource includes 2G, and when the client sends a resource expansion instruction to the server, the client has already used the fixed resource 6G.
The remaining amount of the fixed resource corresponding to the client is the difference between the amount of the fixed resource applied by the client and the amount of the fixed resource already used. If the fixed resource requested by the client includes 8G and the client has used 6G, the remaining amount of the fixed resource corresponding to the client is 2G. It is understood that the fixed resource remaining amount may be 0.
The remaining amount of the streaming resource corresponding to the client is a difference between the amount of the streaming resource requested by the client and the streaming resource already used, and if the streaming resource requested by the client includes 2G and the client already uses 0G of the streaming resource, the remaining amount of the streaming resource corresponding to the client is 2G, and the sum of the remaining amount of the fixed resource corresponding to the client and the remaining amount of the streaming resource corresponding to the client is 2G + 2G-4G.
When the capacity expansion resource amount is greater than the sum of the remaining amount of the fixed resource corresponding to the client and the remaining amount of the mobile resource corresponding to the client, for example, the capacity expansion resource amount is 5G and is greater than the sum of the remaining amount of the fixed resource corresponding to the client and the remaining amount of the mobile resource corresponding to the client, it is indicated that the capacity expansion resource amount applied by the client exceeds the remaining amount of the resource applied by the client, capacity expansion cannot be successful, and the client needs to apply for more resources if the client wants to apply for more resources. At this time, the server side sends a capacity expansion failure instruction to the client side. And the capacity expansion failure instruction is used for notifying the client of capacity expansion failure.
S203: and when the capacity expansion resource amount is larger than the fixed resource residual amount corresponding to the client and is smaller than the sum of the fixed resource residual amount corresponding to the client and the mobile resource residual amount corresponding to the client, allocating the mobile resource of the first resource library to the client.
If the remaining quantity of the fixed resources corresponding to the client is 2G, the remaining quantity of the mobile resources corresponding to the client is 2G, and when the capacity expansion resource quantity is 3G, the capacity expansion resource quantity 3G is larger than the remaining quantity of the fixed resources corresponding to the client 2G, and the capacity expansion resource quantity 3G is smaller than the sum of the remaining quantity of the fixed resources corresponding to the client 2G and the remaining quantity of the mobile resources corresponding to the client 4G, it is stated that the remaining quantity of the resources applied by the client is enough for the client to use, the mobile resources of the first resource pool are allocated to the client.
It can be understood that when the capacity expansion resource amount is smaller than the fixed resource remaining amount corresponding to the client, it indicates that the fixed resource is sufficient for the client to use in an expansion mode, and no mobile resource needs to be allocated to the client.
The resource allocation method provided by the embodiment of the application divides the resource library into fixed resources and flow resources, receives a resource capacity expansion instruction sent by the client during capacity expansion of the client, allocates the flow resources of the first resource library to the client when the capacity expansion resource amount is larger than the remaining amount of the fixed resources corresponding to the client and is smaller than the sum of the remaining amount of the fixed resources corresponding to the client and the remaining amount of the flow resources corresponding to the client, and does not allocate the flow resources of the first resource library to the client when the client does not need the flow resources, so that the resource allocation has real-time performance, resources are saved, and when one client does not need the flow resources, the flow resources can be allocated to other clients for use, the resource allocation is more reasonable, and the resources are fully utilized.
The embodiment of the present application further provides a possible implementation manner, where allocating a streaming resource of a first resource pool to a client includes:
and when the flow resources in the first resource library comprise the flow resources reserved for the client, allocating the flow resources reserved for the client to the client.
If the client has a requirement and the mobile resource is preset to meet the capacity expansion requirement, the mobile resource in the first resource library comprises the mobile resource reserved for the client, and when the capacity expansion resource amount is larger than the fixed resource residual amount corresponding to the client and is smaller than the sum of the fixed resource residual amount corresponding to the client and the mobile resource residual amount corresponding to the client, the mobile resource reserved for the client is distributed to the client.
The embodiment of the present application further provides a possible implementation manner, where before allocating the mobile resource reserved by the client to the client, the resource allocation further includes:
receiving a resource reservation instruction sent by a client, wherein the resource reservation instruction comprises preset time;
and according to the resource reservation instruction, taking part of the flowing resources in the first resource library as the flowing resources reserved for the client within a preset time.
When the client has a service demand and the client estimates a service peak period, the client can send a resource reservation instruction to the server, and the server can receive the resource reservation instruction sent by the client when the resource reservation instruction comprises a preset time. Wherein the predetermined time is the time when the client end reserves the streaming resource. For example, if the client estimates that the time between 18 hours and 23 hours is a traffic peak time, the predetermined time may be 18 hours to 23 hours, so as to reserve the flow resources from 18 hours to 23 hours to meet the traffic demand.
The size of the part of the streaming resources, the size of the streaming resources required by the client, or the size of the streaming resources applied by the client. And in the preset time, no matter whether the client expands the capacity or not, the server side prepares the mobile resource preset by the client for the client to expand the capacity for use.
Referring to fig. 3, a possible implementation manner is further provided in the embodiment of the present application, where allocating a streaming resource of a first resource pool to a client includes:
s301: and when the flow resources in the first resource library comprise the flow resources reserved for the client, allocating the flow resources reserved for the client to the client.
S302: and when the flow resources in the first resource library do not comprise the flow resources reserved for the client and the capacity expansion resource amount is less than the sum of the flow resource residual amount of the first resource library and the fixed resource residual amount corresponding to the client, preempting the flow resources of the first resource library to allocate to the client.
If the mobile resources in the first resource pool do not include the mobile resources reserved for the client, it indicates that the client does not reserve the mobile resources.
Although the mobile resources of the first resource pool may be large, the server may correspond to a plurality of clients, and when the plurality of clients all expand the mobile resources, the remaining amount of the mobile resources of the first resource pool may slowly decrease, the expanded resource amount may be smaller than the sum of the remaining amount of the mobile resources of the first resource pool and the remaining amount of the fixed resources corresponding to the clients, and the expanded resource amount may also be larger than the sum of the remaining amount of the mobile resources of the first resource pool and the remaining amount of the fixed resources corresponding to the clients.
When the capacity expansion resource amount is less than the sum of the flowing resource surplus of the first resource library and the fixed resource surplus corresponding to the client, it is indicated that the resource surplus of the first resource library can also meet the capacity expansion use of the client, but at the same time, other clients may also request capacity expansion, and the flowing resource is limited, and the flowing resource of the first resource library is preempted to be allocated to the client. The probability that the client sending the resource expansion instruction is early can obtain the flowing resources of the first resource library is high.
S303: and when the mobile resources in the first resource library do not comprise the mobile resources reserved for the client and the capacity expansion resource amount is larger than the sum of the mobile resource residual amount of the first resource library and the fixed resource residual amount corresponding to the client, acquiring the mobile resources of the second resource library and allocating the mobile resources to the client.
When the capacity expansion resource amount is larger than the sum of the mobile resource surplus of the first resource library and the fixed resource surplus corresponding to the client, the resource surplus of the first resource library cannot meet the capacity expansion use of the client, and then the mobile resource of the second resource library is obtained to be allocated to the client for use.
The second resource pool may be a resource of an IAAS (Infrastructure as a Service). It can be understood that the first resource library and the second resource library may be located in the same server, or the first resource library and the second resource library may be located in different servers; if the first resource library is located in the first service end and the second resource library is located in the second service end, the first service end is the service end of the client, the second service end is the service end of the first service end, and the second resource library of the second service end expands the capacity of the first resource library of the first service end.
And only when the mobile resources of the first resource library cannot meet the mobile resources of all the clients, the normal operation of all the clients can be guaranteed.
The embodiment of the present application further provides a possible implementation manner, and the resource allocation method further includes:
and when the flowing resource of the first resource library is unsuccessfully occupied, the flowing resource of the second resource library is obtained and distributed to the client.
When the flow resources in the first resource library do not include the flow resources reserved for the client and the capacity expansion resource amount is smaller than the sum of the flow resource residual amount of the first resource library and the fixed resource residual amount corresponding to the client, and when the flow resources in the first resource library are preempted to be allocated to the client, the flow resources in the first resource library fail to be preempted, which indicates that the flow resources in the first resource library are too few to meet the use of the client, the flow resources in the second resource library are obtained and allocated to the client.
The embodiment of the present application further provides a possible implementation manner, and the resource allocation method further includes:
when the usage amount of the mobile resources in the first resource library reaches a first preset proportion, the mobile resources in the second resource library are obtained as standby mobile resources;
and when the usage amount of the flowing resources of the first resource library is smaller than a second preset proportion, releasing part of or all of the flowing resources of the second resource library.
The magnitude of the first predetermined ratio is not limited, for example, the first predetermined ratio may be 85%, 90%, etc. The standby mobile resource, namely the standby resource of the first resource library, can be used by the client in time when the mobile resource of the first resource library is not enough to satisfy the use of a plurality of clients.
The second predetermined ratio is not limited, for example, the second predetermined ratio may be 80%, 85%, etc. The magnitude of the second predetermined proportion may be equal to the magnitude of the first predetermined proportion. Optionally, the size of the second preset proportion is smaller than or equal to the size of the first preset proportion. And releasing part of or all of the mobile resources of the second resource library can reduce the use of the mobile resources of the second resource library, and the resource allocation is more reasonable.
The embodiment of the present application further provides a possible implementation manner, and the resource allocation method further includes:
acquiring the resource amount used by a client;
and when the resource amount used by the client is smaller than the preset release proportion of the fixed resource corresponding to the client, releasing part or all of the flowing resource corresponding to the client.
When the resource amount used by the client is obtained, the resource amount can be obtained in real time.
The magnitude of the preset release ratio is not limited, and the preset release ratio may be 100%, 95%, 80%, and the like. If the amount of resources used by the client is less than 100% of the fixed resources corresponding to the client, 50% or 80% of the mobile resources corresponding to the client can be released, and if the amount of resources used by the client is less than 70% of the fixed resources corresponding to the client, all the mobile resources corresponding to the client can be released.
