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. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. 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.
The present invention will be further described with reference to the following examples.
Fig. 1 illustrates a flow of a method for migrating a container application across a CPU architecture, which may be performed by an apparatus for migrating a container application across a CPU architecture.
As shown in fig. 1, the specific steps of the process include:
step S101: after the container application is migrated across the CPU architecture, acquiring a query rate per second QPS after the container application of the migrated CPU architecture server runs for a preset time period;
step S102: determining whether the QPS of the container application of the CPU architecture server after the migration is consistent with the QPS of the container application of the CPU architecture server before the migration;
step S10: if not, determining a copy expansion coefficient to be adjusted according to the QPS of the container application of the CPU architecture server after the migration and the QPS of the container application of the CPU architecture server before the migration;
step S104: and adjusting the container application copy number of the container application of the migrated CPU architecture server according to the copy expansion coefficient to be adjusted.
In the embodiment of the present invention, in order to make a QPS run on a CPU architecture server after migration of a container application and a QPS run on a CPU architecture server before migration as consistent as possible before and after the container application is migrated across CPU architectures, an empirical value needs to be first set to set a container application copy of the container application of the CPU architecture server after migration. Specifically, before the container application is migrated across the CPU architecture, configuration parameters may be obtained, where the configuration parameters may include a preset application copy number ratio. And then determining the number of the container application copies of the CPU architecture server after the migration according to the preset application copy number proportion and the number of the container application copies of the CPU architecture server before the migration. And finally, when the container application is migrated from the CPU architecture server before migration to the CPU architecture server, setting the container application copy of the CPU architecture server after migration by using the container application copy number of the CPU architecture server after migration.
For example, if the number of container application copies of the CPU architecture server before migration is a, and the ratio of the number of preset application copies included in the configuration parameters is 2.5, a × 2.5 container application copies need to be set for the container application on the CPU architecture server after migration.
By the method, before migration, it can be ensured that the QPS which can be run on the server of the CPU architecture after migration of the container application is completed is consistent with the QPS which can be run on the server of the CPU architecture before migration according to experience.
Specifically, the configuration parameters may further include: the CPU architecture chip manufacturer before the migration, the CPU chip manufacturer after the migration, the primary key ID used for avoiding data duplication, and the description used for remark information.
The configuration parameters may be set through a UI interface, for example, the specific setting of the preset application copy number ratio of the partially-homed CPU architecture server may be as follows:
migrating from the X86 architecture to the arm (first brand) architecture, the preset application copy ratio is set to 2.
Migrating from the X86 architecture to the arm (second brand) architecture, the preset application copy number ratio is set to 1.5.
Migrating from the X86 architecture to the mips (third brand) architecture, the preset application copy number ratio is set to 3.
After the migration of the container application across the CPU architecture is completed, in order to prevent a QPS run on the CPU architecture server after the migration of the container application from being different from a QPS run on the CPU architecture server before the migration, it is necessary to acquire a QPS after a preset period of time of the container application running on the CPU architecture server after the migration. The preset time period may be set empirically.
And then, inquiring the QPS of the container application when the container application runs on the CPU architecture server before migration in the database table, comparing the QPS with the database table, and comparing whether the QPS is consistent with the CPU architecture server before migration, wherein if so, the QPS does not need to be processed. If the difference is not consistent, the copy expansion coefficient to be adjusted needs to be determined according to the QPS of the container application of the CPU architecture server after the migration and the QPS of the container application of the CPU architecture server before the migration.
That is, after the migration is completed, there is a possibility that the QPS generated after the running of the container application copy number of the container application of the CPU architecture server after the migration set according to the empirical value may be inconsistent with the QPS of the container application of the CPU architecture server before the migration, and therefore, here, it is necessary to compare the QPS of the container application of the CPU architecture server after the migration and the QPS of the container application of the CPU architecture server before the migration with each other, and when it is determined that the QPS of the container application of the CPU architecture server after the migration and the QPS of the container application of the CPU architecture server before the migration are inconsistent, the copy expansion coefficient to be adjusted is calculated.
Specifically, the replica expansion coefficient to be adjusted may be determined according to formula (1):
the formula (1) may be:
Wherein α represents a copy expansion coefficient to be adjusted, QPSsrc represents a QPS of the container application of the CPU architecture server before migration, and QPSdst represents a QPS of the container application of the CPU architecture server after migration.
It should be noted that, the QPS of the container application of the CPU architecture server before migration here is an average value of QPS of the container application of the CPU architecture server before migration counted by the system before migration within a preset time period, and is stored in the database for invocation. The preset time period may be set empirically, and may be, for example, 3 months.
After the copy expansion coefficient to be adjusted is obtained, a kubernets standard interface can be called according to the adjusted copy expansion coefficient, and the number of the container application copies can be automatically adjusted.
It should be noted that the CPU architecture server before migration and the CPU architecture server after migration are two different CPU architectures, for example, the CPU architecture before migration may be an X86 architecture, and the CPU architecture after migration may be a localization architecture.
In order to better optimize the above scheme, after the number of container application copies of the container application of the migrated CPU architecture server is adjusted, the number of container application copies may be further finely adjusted, which may specifically be as follows:
firstly, a QPS of the container application of the migrated CPU architecture server may be collected at a preset time period, and then when it is determined that the collected QPS of the container application of the migrated CPU architecture server is inconsistent with the QPS of the container application of the CPU architecture server before migration, the copy expansion coefficient to be adjusted is re-determined, and the number of container application copies of the container application of the migrated CPU architecture server is adjusted according to the re-determined copy expansion coefficient to be adjusted.
The preset time may be set empirically, for example, may be set to 3 months, 6 months, 12 months, etc.
The embodiment of the invention shows that after the container application is migrated across the CPU architecture, the QPS of the migrated CPU architecture server after the container application runs for the preset time period is collected, whether the QPS of the container application of the migrated CPU architecture server is consistent with the QPS of the container application of the CPU architecture server before the migration is determined, if not, the copy expansion coefficient to be adjusted is determined according to the QPS of the container application of the migrated CPU architecture server and the QPS of the container application of the CPU architecture server before the migration, and the number of the container application copies of the container application of the migrated CPU architecture server is adjusted according to the copy expansion coefficient to be adjusted. Therefore, before and after the container application is migrated, the copy coefficient does not need to be set manually, the copy adjustment is finished in a self-adaptive mode, the consistency of the QPS of the container application of the CPU architecture server after the migration and the QPS of the container application of the CPU architecture server before the migration is ensured, and therefore the usability of a service system and the use experience of a terminal user are ensured.
