Description
Technical Field
The invention relates to the technical field of load balancing, in particular to a soft load resource processing method and device based on a container cloud.
Background
With the rapid development of internet and cloud computing technologies, web applications based on virtualization are the most important and widespread applications at present. At present, the information exchange amount based on web application is exponentially increased, an application server faces the pressure of sharply increased access amount, extremely high requirements are brought to the response capacity and the processing capacity of the application server, therefore, various resources of a data center need to be effectively integrated, and the resource control and scheduling of the data center play a decisive role in the normal operation of business.
Due to the objectively existing factors of the server memory, the CPU processing speed and other related aspects, when service expansion, hot spot activity push-out or periodic service peaks are performed, the soft load server cannot process all requests in time, which inevitably causes the situations of soft load queue blockage, slow response, request loss, even service inaccessibility, and the like. In a high concurrent high-traffic peak period, the prior art manually expands the soft load according to a certain strategy, manually expands the soft load by taking a virtual machine as a unit when performing traffic expansion, hot spot activity push-out or periodic traffic peak, and manually recovers the soft load by taking the virtual machine as a unit when the hot spot activity is finished or the traffic peak returns to normal. In the prior art, the soft load is manually expanded and recovered according to experience, and meanwhile, the requirement of soft load resources cannot be quickly responded on the basis of a virtual machine, so that unstable service access is caused.
Specifically, as shown in fig. 1, when a user performs a large concurrent access to an application system, a principle of an existing soft load resource processing method is that first, hard load balancing is performed through a hard load or an LVS, and meanwhile, a soft load is accessed to ensure normal access of a service. The data center can manually deploy the data center soft load server in advance by taking a virtual machine as a unit by operation and maintenance personnel according to the current use pressure condition of the soft load and the historical experience of operation and maintenance. Therefore, the problems that the soft load pressure is too large to cause downtime and the like due to too large access amount of the service deployed in the data center can be avoided to some extent.
Typically, service access to a data center will fail in several cases: 1) when the service access amount suddenly increases, the soft load in the prior art adopts a virtual machine mode, the deployment period is long, the flexibility is poor, and the soft load requirement cannot be responded in time; 2) in the two cases, the general traffic generally lacks an empirical value or is difficult to predict in the early stage according to the empirical value, and meanwhile, the prediction cannot be made according to the resource use condition of the current soft load; 3) generally, there are many factors affecting normal access of a service, and various resource shortages caused by various factors affect normal operation and access of the service, so that the on-line service cannot be normally provided for a user to access. In the event of a serious failure, it will result in most users not having access to the business system, which is unacceptable for large or core systems.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the prior art, although the soft load resources can be manually scheduled through operation and maintenance experience and the use conditions of a CPU, a memory and the like of the soft load server to ensure normal access to the service, in most cases, it is difficult to predict the concurrent request amount of the service and the quick response to the service demand, which causes that the soft load resources cannot be dynamically expanded and contracted in time, resulting in failure of service access of the data center and failure of normal service resources to be fully utilized.
In the prior art, the soft load balancing elastic expansion capability is weak, the deployment mode is constructed by taking a virtual machine as a unit, the expansion process is complex, and the deployment time is long. When the traffic volume suddenly increases, rapid deployment expansion and dynamic scheduling cannot be carried out, so that service faults are caused, meanwhile, the soft load balance cannot be automatically reduced, and certain reservation and waste of system resources exist.
Fig. 2 is a schematic flow chart of a container cloud-based soft load resource processing method according to an embodiment of the present invention.
It should be noted that the container cloud encapsulates the entire software runtime environment by using the container as a basic unit for resource partitioning and scheduling, and provides a platform for building, publishing, and running the distributed application.
As shown in fig. 2, the method of this embodiment includes:
s21: acquiring soft load queue lengths of a soft load resource pool at multiple moments, wherein the soft load queue lengths at the multiple moments at least comprise the soft load queue length at the current moment;
it should be noted that the soft load resource pool according to the embodiment of the present invention includes a plurality of soft load containers, and each soft load container (as shown in fig. 3) runs a soft load service. The soft load queue stores the concurrent requests to be processed, and the number of the concurrent requests to be processed is the length of the soft load queue.
In practical application, the host Master node obtains the soft load queue length at multiple moments through the performance of the data center soft load resource pool and the log data.
S22: acquiring queue mutation information according to the soft load queue lengths at the multiple moments;
it can be understood that if there is a large difference between the current time and the previous time period in the length of the soft load queue, which indicates that the traffic request amount changes greatly, the capacity of the soft load needs to be expanded or reduced. Therefore, the embodiment of the invention obtains the queue mutation information through the soft load queue length at multiple moments, and can dynamically expand or reduce the capacity of the soft load resource through the queue mutation information.
S23: processing the soft load resources by taking the soft load container as a unit according to the queue mutation information;
understandably, the processing procedure of the soft load resource comprises the capacity expansion and the capacity reduction of the soft load resource; the expansion of the soft load resource refers to increasing the soft load container, and the contraction of the soft load resource refers to decreasing the soft load container.
In practical application, if elastic expansion and contraction are needed, the host Master node sends an elastic expansion and contraction instruction to the data center soft load resource pool to perform soft load expansion and contraction and records the elastic expansion and contraction event. And if the soft load resource pool of the data center cannot meet the resource requirement required by elastic expansion, informing a super administrator to perform expansion processing on the resource pool, and performing elastic scheduling again.
According to the soft load resource processing method based on the container cloud, provided by the embodiment of the invention, the bottom layer resources are integrated based on the container technology, and the soft load service and the application service share the resources, so that the resource utilization rate is improved; the containerized soft load service overcomes the defect that the soft load service cannot be rapidly deployed in the prior art, automatically performs dynamic capacity expansion or capacity reduction on soft load resources by taking a soft load container as a unit, and reduces service interruption caused by high concurrent high flow or burst flow of a system.
In an optional implementation manner of the embodiment of the present invention, similar to the method in fig. 2, obtaining the queue sudden change information according to the soft load queue lengths at the multiple time instants includes:
acquiring a first queue mutation factor and a second queue mutation factor according to the soft load queue lengths at the multiple moments, wherein the first queue mutation factor is a queue mutation factor before the current moment, and the second queue mutation factor is a queue mutation factor including the current moment;
and acquiring queue mutation information according to the difference value of the first queue mutation factor and the second queue mutation factor.
Specifically, the first queue mutation factor is obtained according to the following formula:
obtaining the second queue mutation factor according to the following formula:
wherein ε 1 represents a first cohort mutation factor and ε 2 represents a second cohort mutation factor; n represents the number of the obtained soft load queue lengths; x represents the soft load queue length at the current time, xiRepresenting the soft load queue length at a difference i from the current time.
For example, the current time is 12 points, and the lengths of the soft load queues corresponding to three times, namely 12 points, 11 points and 10 points, are obtained. And calculating to obtain the queue mutation factor excluding the current 12-point according to a calculation formula of the first queue mutation factor, and calculating to obtain the queue mutation factor including the current 12-point according to a calculation formula of the second queue mutation factor.
Further, the processing the soft load resource by taking the soft load container as a unit according to the queue sudden change information includes:
if the difference between the second queue mutation factor and the second queue mutation factor is larger than a first preset threshold value, carrying out capacity expansion on the soft load resource by taking a soft load container as a unit;
if the difference between the first queue mutation factor and the second queue mutation factor is larger than a first preset threshold value, carrying out capacity reduction on the soft load resource by taking a soft load container as a unit;
further, when the absolute value of the difference between the first queue mutation factor and the second queue mutation factor is smaller than a first preset threshold, the method further comprises:
acquiring a weight value of resource processing according to the length, the concurrency quantity and the response time of the soft load queue at the current moment;
if the weight value of the resource processing is larger than a second preset threshold value, carrying out capacity expansion on the soft load resource by taking a soft load container as a unit;
and if the weight value of the resource processing is smaller than a third preset threshold value, carrying out capacity reduction on the soft load resource by taking a soft load container as a unit.
It should be noted that the concurrency amount in the embodiment of the present invention refers to the number of concurrent requests being processed.
It can be understood that when the soft load queue is judged and known not to have sudden change according to the queue sudden change factor, the soft load resource is processed according to the length, the concurrency and the response time of the soft load queue at the current moment.
Specifically, the obtaining a weight value of resource processing according to the soft load queue length, the concurrency amount, and the response time at the current time includes:
respectively acquiring a degree coefficient of the soft load queue length, a degree coefficient of the concurrency amount and a degree coefficient of the response time at the current moment according to the concurrency amount and the response time of the soft load queue length at the current moment;
and acquiring a weight value of resource processing according to the degree coefficient of the soft load queue length at the current moment, the degree coefficient of the concurrency quantity and the degree coefficient of the response time.
In practical application, the degree coefficients of the three indexes need to be assigned according to an assignment reference table, and the operation can be dynamically distributed by an administrator according to different application scenes and time periods. The assignment reference table is shown in table 1:
table 1 assignment reference table
| Of extreme importance | Of strong importance | Of obvious importance |
| 9 | 7 | 5 |
And carrying out normalization processing according to the assignment reference table to obtain degree coefficients corresponding to the three indexes. x is the number ofi_normNamely, the degree coefficient of the index, the specific calculation method is as follows:
wherein xiIndicating the value assigned to the i-th entry in the reference table.
For example, the length of the soft load queue at the current time is 10, and the concurrency is 100; the response time is 30 (in ms), and the degree coefficients of the three indexes are obtained according to the corresponding importance degrees. (it is assumed that the importance of the queue length: 9; the importance of the concurrency amount: 7; the importance of the response time: 5).
Therefore, the degree coefficient of the soft load queue length at the present time is 9/21; the degree coefficient of concurrency was 7/21; the degree coefficient of the response time is 5/21. The three are added to obtain a value. This value is compared to upper and lower threshold values.
In practical application, the most appropriate upper and lower limit thresholds can be obtained through multiple experiments according to actual operating conditions, and the upper and lower limit thresholds can also be manually specified by an administrator according to soft load requirements.
In practical application, the soft load instance of the back end is updated by calling the hard load interface. The soft load example and the loading information are started first, and then the hard load information is updated, so that no perception is ensured when the service is accessed.
The embodiment of the invention combines a containerization technology, integrates bottom resources, shares a resource pool by soft load service and application service, maximally utilizes resources of a data center, reduces waste and redundancy of the resources and improves the resource utilization rate of the data center. The method has good popularization value for the container cloud environment of the data center. The soft load service is containerized, the dynamic expansion and elastic expansion capability of soft load resources can be realized, the response time of a data center can be effectively prolonged, and the soft load resources can be quickly expanded and contracted aiming at large flow and large concurrent services. And by means of a two-stage judgment mechanism, the soft load use condition is comprehensively considered, queue variation factors are added, the soft load state can be judged more accurately, fine-grained elastic expansion and contraction resources are realized, and the method has a high practical value in a large-scale production environment.
