Detailed Description
The invention will be described in further detail with reference to the drawings and the detailed description.
A method for efficiently utilizing computing resources based on cloud computing, comprising:
1: and (5) computing the resource super-proportion setting.
Before using the physical server and the computing resources, the user can set the overestimate proportion of the computing resources of the physical server, i.e. the computing resources of the physical server are overestimated according to a certain proportion. The super-divided computing resources can be distributed to more virtual machines for use, so that the elasticity and fault tolerance of the system are improved. The visual interface is designed by utilizing the front-end development framework of the Vue, the proportion can be set on the visual interface, proportion data is submitted to the back end through the interaction capability of the front end and the back end of the Vue, and the back end stores the data in a local database or a relational database so as to realize the visual computing resource planning use.
The relationship between the physical CPU and the virtual machine vCPU, a 2U (thickness) physical server is generally configured with 2 physical CPUs, each CPU has a plurality of cores, and after the Hyper-Threading technology is started, each core has 2 threads (threads); one vCPU corresponds to one Thread in the virtualized environment.
The physical server computing resources refer to various hardware resources owned by the physical server, and the various hardware resources together form the overall computing power of the physical server, including:
processor (CPU): a core component responsible for performing computing tasks;
memory (RAM): temporary space for storing programs and data;
a storage device: the system comprises a hard disk, a solid state disk and the like, and is used for permanently storing data;
network interface: connected to other devices and services through a network;
display card (GPU): can be used for high-performance computing, machine learning and other tasks.
The physical server superdivision is realized on the basis of KVM (virtual machine), each VM is a QEMU process of a user space in the open source virtualization KVM, the vCPU allocated to the virtual machine is a Thread derived from the QEMU process, the virtual machine is dynamically scheduled to the physical CPU based on time division multiplexing by the Linux kernel to run, and the KVM can support vCPU superdivision (over-limit) per se, so that the number of vCPUs allocated to the virtual machine can exceed the total number of physical CPU threads. Therefore, in cloud computing, a user can superdivide a CPU according to different superproportions of 1:1, 1:2, 1:4 and the like according to the load of a service, for example, a previous physical CPU core is 20 cores, and a hyper-thread is started to be 40 cores; if the super division is performed according to the ratio of 1:2, the allocatable resource becomes 80 cores, so that more virtual machine resources can be created.
Memory superdivision, in open source virtualized KVM, memory is also an over-use (over-commit) allowed, and KVM enables the total amount of memory allocated to a virtual machine to be greater than the total amount of physical memory actually available. Because the operating system of the virtual machine and the application programs running by the operating system of the virtual machine do not always use 100% of the memory allocated by the operating system of the virtual machine, and the utilization rate of the memory of a plurality of virtual machines on a host machine generally cannot reach 100% at the same time, the memory can be oversubscribed. The super allocation ratio of the memory is similar to that of the CPU, and the super allocation ratio can be different according to different proportions of 1:1, 1:2 and the like, for example, the physical memory is 8G, and the super allocation ratio of 1:2 can allocate 16G to the virtual machine. In practical application, in order to ensure service performance, the memory super-proportion is lower.
The computing resources after the physical server is super-configured comprise a CPU, a memory and the like.
The present embodiment follows the following formula:
11: the calculation formula of the total CPU core number after each physical server is super-configured,
wherein, C is the number of CPU cores used in the example specification, and the unit is VCPUs; n is the number of example specification seeds, and the unit is the seeds; s is an example specification; x is the number of the example specifications; i is a certain example specification; j is the server number.
12: the total memory calculation formula after each physical server is overduned,
wherein M is the memory space used by the example specification, and the unit is GB; n is the number of example specification seeds, and the unit seeds; s is an example specification; x is the number of the example specifications; i is a certain example specification; j is the server number.
2: the computing resource plan is visualized.
Before using the physical servers and the computing resources, the user needs to perform a usage plan of the computing resources, i.e. plan out the specification of the running examples and the number of the running examples after the servers are over-matched. Through a visual interface, a user can check and adjust the configuration and allocation conditions of the computing resources after the server is over-allocated, so that the computing resources after the server is over-allocated are abstracted into grids on the interface for facilitating the user resource planning, and the user can fill up the small grids representing the computing resources after the server is over-allocated by using the instance specification, thereby indicating that the computing resources after the server is over-allocated by the server are planned. The planning data stores the specification and quantity information of each server executable instance in a structured form into a database for subsequent management and instance creation for use by the optimal selection server algorithm.
3: instance creation automatically selects the optimal server algorithm.
When the computing resource is used for instance creation, the server with the largest data volume for creating the specification instance is found from the computing resource planning data, namely the optimal server is used for deploying and operating the instance, and meanwhile, the corresponding instance specification data in the computing resource planning data of the instance deployment server is automatically subtracted by one. For example, there are 3 nodes in the current cluster, the specification of the c4m8 instance in each Node is shown in the following table, if an instance of c4m8 is to be created, it is determined that the number of the allowable creation specifications of the c4m8 instance in the Node1 is the largest, so the algorithm will create the instance on the Node 1; after being distributed to the Node1, the Node can create a specification number of which is obtained by subtracting 1 from 8 and then obtaining 7.
An example is a basic computing resource unit in cloud computing, which generally refers to an independent computing unit where virtual machines run on a cloud computing platform. Each instance has its own independent operating system, computing resources, network configuration, etc., and can perform operations such as creation, start, stop, release, etc. according to the needs of the user.
An instance specification is a parameter used in cloud computing services to describe the configuration of virtual machine resources, and generally includes vCPU core number, memory size, and network performance. Different cloud computing providers may provide a variety of different instance specifications to meet different business needs and budget constraints for users.
The present embodiment follows the following formula:
31: the optimal server algorithm formula is automatically preferred,
I i =max(X ij );
wherein I is an example; x is the number of the example specifications; i is a certain example specification; j is the server number.
4: and (3) releasing the computing resources.
After the computing resources are used, when a user does not need some examples, the computing resources can be destroyed through a visual interface, and occupied computing resources can be automatically released when the computing resources are destroyed. The method comprises the steps of deleting the instance on the node where the idle instance is located, and adding the number of the created specifications by the node. This reduces unnecessary waste of resources and fragmentation while enabling the computing resources to be reused.
Fig. 1 is a schematic diagram of a method for efficiently utilizing computing resources based on cloud computing according to a first embodiment of the present invention, and as shown in fig. 1, a visual computing resource planning form of the present invention includes:
examples specification list includes c1m1, c1m2, c2m2, c2m4, c2m8, c4m4, c4m8, c4m16, c8m8, c8m16, and c16m32; the example specifications listed in the list may be used, and the example specifications are interpreted as configurations of the CPU and the memory, for example, c2m4 corresponds to a 2-core CPU and a 4G memory. Each instance specification in the list can be added to the right CPU-available resources, the memory-available resources and the node resource allocation list by a double-click or drag operation, for example, the c4m4 specification in the double-click or drag list is to the right, 4 squares in the CPU-available resources are occupied (light gray is changed to dark gray), and 4 squares in the memory-available resources are occupied (light gray is changed to dark gray).
Each grid in the legend of the CPU available resource framework represents CPU resources for 1 core:
the grey grid with triangles represents server computing resources that have been used, here CPU resources that have been used, cannot be used by other instances;
the light grey grid represents the CPU resources of the server to be allocated, i.e. the CPU resources which can be used;
the dark grey grid represents the allocated server CPU resources, i.e. the CPU resources that have been occupied.
Each cell in the legend of the memory-available resource framework represents 1GB of memory resources:
the grey grid with triangles represents server computing resources that have been used, here referring to memory resources that have been used, and cannot be used by other instances;
the light grey grid represents memory resources that can be used by the server memory resources to be allocated;
the dark grey grid represents allocated server memory resources, i.e. memory resources that have been occupied.
In the super-configuration framework, the super-configuration proportion of the CPU and the memory of the current server can be checked and modified; as shown in fig. 1, the physical resources available to the server are a 16-core CPU, a 16GB memory, and the number of cores of the CPU is super-configured to be 125% according to the legend, and the number of cores of the CPU after super-configuration is 20 cores (16 cores x 125% = 20 cores); the memory is over-matched by 150%, and the memory after over-matching is 20GB (16 GB. Times.150% =24 GB).
The node resource allocation resource list is displayed with specification names, CPU core number (unit is vCPU), memory (unit is GB), allocation quantity and operation; the specification name corresponds to an instance specification in the instance specification list by adjusting the specification allocation number in the allocation number column. The number increase is a grid which automatically occupies CPU and memory available resources (changing from light gray to dark gray), and the number increase is determined by a specification attribute, such as the example specification of c1m2 in the figure, which is interpreted as a grid which occupies 1 CPU available resource and a grid which occupies 2 memory available resources. The amount of reduction is to automatically release CPU memory available resource grids (from dark grey to light grey), the amount of reduction is determined by specification attributes, e.g. specification c1m2, 1 CPU available resource grid will be released, and 2 memory available resource grids will be released. The deleting operation in the operation will automatically release the CPU and the available resource grid of the memory. If the specification number of c1m2 in the deletion diagram is 4, the number of lattices of the released CPU available resources is 4 (1*4 =4), and the number of lattices of the released memory available resources is 8 (2×4=8); if the specification number of the deleted examples is c4m4 and is 1, the number of grids of the released CPU available resources is 4, and the number of grids of the released memory available resources is 4; if the specification number of the deleted instance is c1m1, the number of grids of the released CPU available resources is 2, and the number of grids of the released memory available resources is 2; if the specification number of the deleted example is c2m2, the specification number is 4, the number of lattices of the available resources of the released CPU is 8, and the number of lattices of the available resources of the released memory is 8. And submitting the specification names and the corresponding numbers in the resource allocation list to the back end during storage, and storing the specification names and the corresponding numbers in a database.

step S3: automatically selecting a best server algorithm to select a best server based on the instance creation; when an instance is created, a server with the largest number of the instances with the specifications can be created from the computer resource planning data, namely an optimal server is found to deploy and run the instance, and meanwhile, the operation of subtracting one from the corresponding instance specification data in the resource planning data is calculated for the instance deployment server;
step S4: the system creates and runs an instance on the selected server, ending the automatic selection.
