Detailed Description

In order to make the technical solutions of the present disclosure better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.

It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in sequences other than those illustrated or otherwise described herein. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

At present, for a large data cluster, for example, a large data cluster of 10 ten thousand levels, a service deployment method mainly includes manually generating cluster configuration information for a small cluster, where the cluster configuration information includes services to be deployed to the small cluster; after deployment and normal operation verification, storing the cluster configuration information in a configuration center, acquiring the cluster configuration information from the configuration center in an expansion mode, and manually adjusting and deploying the cluster configuration information to a big data cluster.

However, in the above method, the actual configuration on the large data cluster is inconsistent with the deployment configuration stored in the configuration center, and is difficult to unify, so that the cluster management cost is high, and the cluster management efficiency is poor.

The service deployment method is mainly used for solving the problems that the actual configuration on a big data cluster in the related technology is inconsistent with the deployment configuration stored in a configuration center, the unification is difficult, the cluster management cost is high, and the cluster management efficiency is poor. According to the service deployment method, the number of the roles obtained after the combination is far smaller than the number of the services through the combination of the services, the workload during service deployment can be reduced, the services are deployed at one time, the actual deployment configuration on the big data cluster is consistent with the deployment configuration obtained from the configuration center, the management is easy, the cluster management cost is reduced, and the cluster management efficiency is improved.

FIG. 1 is a flow chart of an illustrative method of service deployment in accordance with an exemplary embodiment.

The execution subject of the embodiment of the present disclosure may be a service deployment apparatus, and the service deployment apparatus may be, for example, a configuration center of a cluster. The configuration center of the cluster may be, for example, one or more servers in the cluster, which are responsible for cluster management.

As shown in fig. 1, the service deployment method may include the steps of:

in step S101, configuration information of each service in the project to be deployed is acquired.

In the embodiment of the present disclosure, the cluster may be a cluster in which a service is not deployed, or may be a cluster in which a service is deployed but a redeployment condition is satisfied, where the redeployment condition includes at least one of the following conditions: there is a change in servers in the cluster, a change in projects deployed on the cluster, and a change in services in projects deployed on the cluster. In one embodiment, a project specifies a task to be implemented, and the task may be divided into a plurality of subtasks, and each subtask may be implemented by a plurality of services. That is, the task specified by the project is implemented by the service in the project. For example, a project may be a storage task that may be split into multiple sub-storage tasks. In another embodiment, the items include services that need to be provided, such as storage services, search services, and the like.

In the embodiment of the present disclosure, a cluster that has not deployed services may be a cluster that has not deployed services at a time; or a cluster in which services have been deployed but the deployed services are deleted. In the embodiment of the present disclosure, the change of the server in the cluster means that a new server is added to the cluster, or a part of servers is reduced in the cluster, and the like. When a cluster is expanded or a failed server is replaced, a new server is generally added to the cluster. When a server in the cluster fails, the failed server is deleted, which results in a reduction in the number of servers in the cluster.

In the embodiment of the present disclosure, a determination manner of a change in a project deployed on a cluster is as follows: and comparing the identification of the project on the cluster at the current time point with the identification of the project on the cluster at the previous time point to determine whether the project deployed on the cluster has changes. For example, if each service of the project B is deployed on a cluster of each service of the project a, the service deployed on the cluster at this time is partially owned by the project a, and if the service deployed on the cluster is owned by the project B, the project is changed; and if all the services after the new service is deployed on the cluster belong to the project A, the project is not changed.

In the embodiment of the present disclosure, a service in a project deployed on a cluster has a change, which may be determined by an identifier of the service in the project, and the identifier of the service in the project at a current time point is compared with an identifier of the service in the project at a previous time point to determine whether the service in the project has a change. For example, new services belonging to the project a are deployed on a cluster of each service where the project a has been deployed, and when the number, name, and the like of the services marked with the project a change, it is determined that the services in the project a have changed; if the number, name, etc. of the services marked with item a in the cluster have not changed, it is determined that there is no change in the services in item a.

In step S102, the services in the project to be deployed are combined to obtain one or more service combinations and a role corresponding to each service combination.

In this embodiment of the present disclosure, the process of the service deployment apparatus executing step 102 may be, for example, combining services in the item to be deployed according to a service combination principle to obtain one or more service combinations and a role corresponding to each service combination. Wherein, the service composition principle needs to satisfy at least one of the following conditions: (1) the method comprises the following steps that conflicts do not exist among a plurality of services in one service combination, and the plurality of services in the service combination can provide services; (2) when a plurality of services in one service combination are combined, the service efficiency can be improved, or the service efficiency of a single service can be ensured, and the influence of the use of one service on the use of another service is avoided; that is, the total service efficiency of the individual services in the service combination is greater than or equal to the sum of the service efficiencies of the individual services in the service combination; (3) when one service combination cannot provide services, other service combinations can provide similar functions, namely, a plurality of services with similar functions cannot be placed in the same service combination, so that the failure probability of the whole project is reduced as much as possible. (4) In order to ensure the service efficiency of each service combination and further ensure the service efficiency of the server with the service combination, the number of services in the service combination can be limited, and the situation that the service in one service combination is too much and the service in the other service combination is too little can be avoided. It should be noted that the total service efficiency of each service in the service combination is a total service efficiency determined by combining each service in advance, or a total service efficiency estimated according to whether there is a relationship among the functions, consumed resources, services, and the like of each service.

It should be noted that, taking whether there is a relationship between the consumed resources and the services as an example, the estimation manner may be, for example, if the service a is a controlled service, the service B is a controlled service, and the service B calls the service a, at this time, the total service time may be the service time of the service B, and then the total service efficiency is determined according to the total service time. For another example, if the service a and the service B have no association relationship, and if the resource types consumed by the service a and the service B are different, the services can be performed simultaneously, the total service time may be the maximum time of the service a and the service time of the service B, and the total service efficiency is determined according to the total service time; if the resource types consumed by the service a and the service B are the same and the services cannot be simultaneously serviced, the total service time may be the total service time of the service a plus the total service time of the service B, and the total service efficiency is determined according to the total service time.

Therefore, on the basis of the above conditions, the service composition principle may include at least one of the following principles: the method comprises the steps that a preset service combination list, different services in the same item cannot be combined together, a control type service and a controlled type service in a base layer service can be combined together, a control type service and a controlled type service in different items in a non-base layer service can be combined together, a controlled type service in a non-base layer service cannot be combined together, and the number of services in service combination is smaller than or equal to a preset number threshold.

In the embodiment of the present disclosure, the service combination in the preset service combination list is a combination frequently adopted among a plurality of services, for example, the service a in the item 1 and the service B in the item 2 are frequently combined together, and then the combination of the service a and the service B is added to the service combination list.

In the embodiment of the disclosure, different services in the same project cannot be combined together, so that different services in the same project can be placed in different service combinations, and then different service combinations are deployed on different servers, so that when a certain server fails, the functions of the services on the server can be realized by adopting the services on other servers. For example, a project includes a service a and a service B, where the service a and the service B provide different services, and if the service a and the service B are combined together and are deployed on the same server, when the server fails, both the service a and the service B may fail to provide the service. If the service a and the service B are deployed on different servers, the number of services that cannot be provided when the servers fail is reduced.

In the embodiment of the present disclosure, it should be noted that each service in a project is hierarchical, and includes a base layer service and a non-base layer service. The base layer service provides data computation and storage management for the base layer, such as the data layer. The non-base layer service is a service for executing logic processing or the like in a business logic layer or an application layer, and these services perform logic processing based on data provided by the base layer service. In addition, the services can be divided into two types, one is a control class service, and the other is a controlled class service, wherein the controlled class service provides services, such as a data storage service, a data deletion service, and the like, according to the invocation of the control class service. Control class services, such as data management services, invoking data storage services, data deletion services, and the like, to implement data management.

In the embodiment of the disclosure, the control class service and the controlled class service in the base layer service can be combined together. For example, if the control class service a and the controlled class service B are not combined together and are deployed on two different servers, because there is a control relationship between the control class service a and the controlled class service B, as long as one of the servers fails, neither the control class service a nor the controlled class service B can provide services. If the control type service A and the controlled type service B are combined together and are deployed on the same server, because the probability a of the failure of one server is smaller than the probability a + B of the failure of only one server in the two servers, the control type service and the controlled type service in the base layer service can be combined together, and therefore the failure time of the whole project can be reduced as much as possible.

In the embodiment of the disclosure, the control class service and the controlled class service of different items in the non-base layer service can be combined together. Because the control services and the controlled services of different projects are not affected with each other, no calling relation exists, and the condition that resources are occupied by the provided services is less, the control services and the controlled services of different projects are combined together and deployed on the same server, so that the service efficiency can be improved to a certain extent.

In the embodiment of the disclosure, the controlled services in the non-base layer services cannot be combined together. Because the controlled services need to occupy a large amount of resources, if the controlled services in the non-base layer services are combined together, the situation that a plurality of controlled services occupy the resources may occur, and the service efficiency is reduced to a certain extent. Therefore, the controlled services in the non-base layer services cannot be combined together, and the service efficiency can be effectively improved.

In the embodiment of the present disclosure, in order to avoid an excessive number of services deployed on the same server, the number of services in a service combination needs to be less than or equal to a preset number threshold. The number of services in the service combination is ensured to be less than or equal to the preset number threshold, so as to avoid the problems that the number of services deployed on some servers is too large, the number of services deployed on some servers is too small, and the service efficiency is unbalanced, so that the overall service efficiency is poor.

In step S103, roles are assigned to the servers in the cluster according to one or more service combinations and the role corresponding to each service combination.

In the embodiment of the present disclosure, the process of the service deployment apparatus executing step S103 may be, for example, allocating candidate roles to each server according to one or more service combinations and the role corresponding to each service combination; for each server, when the candidate roles of the server are multiple, acquiring services in a service combination corresponding to the multiple candidate roles, and generating a service set; when the service in the service set meets the service combination principle, determining the candidate role of the server as the role of the server; and when the service in the service set does not meet the service combination principle, adjusting the candidate role of the server until the service in the service set meets the service combination principle.

In the embodiment of the present disclosure, the candidate roles of the servers may be adjusted, for example, in such a manner that, for each server, a service that does not satisfy the service combination principle in the service set of the server is obtained; determining the role corresponding to the service combination to which the service belongs as a conflict role; the conflicting roles are assigned to other servers. The service combination corresponding to a single role satisfies the service combination principle, but the service set generated by the service combination corresponding to a plurality of roles does not necessarily satisfy the service combination principle. Therefore, for a server, in a case that the server is assigned with a plurality of candidate roles, the service deployment apparatus needs to generate a service set according to a service combination corresponding to the plurality of candidate roles, and determine whether the service set satisfies a service combination rule; if the service combination principle is not satisfied, determining a candidate role of the conflict, and allocating the candidate role of the conflict to other servers, the server will not be allocated with the candidate role of the conflict. In addition, if the number of the conflicting candidate roles is too large or the percentage of the conflicting candidate roles is too large, it indicates that the role assignment is not reasonable or the service combination is not reasonable, and the role assignment or the service combination can be reassigned.

In the embodiment of the disclosure, for each server, when the candidate role of the server is single, the candidate role of the server may be directly determined as the role of the server.

In step 104, deployment configuration of each server is generated based on the role of each server and configuration information of each service in the service combination corresponding to the role of the server.

In this embodiment of the present disclosure, if a role of a certain server is single, the deployment configuration of the server may be generated according to configuration information of each service in a service combination corresponding to the single role. For example, if the service combination corresponding to the single role includes service a and service B, the deployment configuration of the server is generated according to the configuration information of service a and the configuration information of service B. For example, the deployment configuration of the server includes: configuration information of service a and configuration information of service B.

In this embodiment, if there are multiple roles of a certain server, the deployment configuration of the server may be generated according to configuration information of each service in a service combination corresponding to the multiple roles. For example, if the service combinations corresponding to the plurality of roles are the first service combination and the second service combination respectively; and generating deployment configuration of the server according to the configuration information of the service A, the configuration information of the service B, the configuration information of the service C and the configuration information of the service D.

In this embodiment of the present disclosure, in order to ensure real-time update of the deployment configuration of each server, after step S104, the method may further include the following steps: monitoring a configuration information change request, wherein the configuration information change request comprises a target service and configuration change content of the target service; and updating the configuration information of the target service according to the configuration change content of the target service when the configuration information change request is monitored.

In the embodiment of the present disclosure, the request for changing the configuration information may be that the configuration information of the service is manually modified by the user and then is actively reported to the service deployment device by the server.
