In public cloud or private cloud scenarios, a general deployment architecture is that the PaaS platform is located in a management public area, a component management console service is located in a preset resource area, and a resource host of an actual deployment instance node is located in a tenant VPC area.

[0040] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0041] Figure 1 A flow schematic diagram of the cloud cache database construction processing method based on the finite state machine provided in an embodiment of the present application is shown in the figure. Figure 1 The present application provides a cloud cache database construction processing method based on a finite state machine, which comprises the following steps:

[0042] In step S101, the component console receives the work order information issued by a tenant through a PaaS platform, and determines the corresponding construction operation according to the work order information, and calls the underlying Agent proxy service to implement the construction operation.

[0043] Specifically, the cloud cache database construction processing method based on the finite state machine in the present embodiment can be adapted to Redis database and related derivative cloud cache database products supporting its protocol, and is generally delivered in a cloud platform as a service (PaaS) mode, that is, the tenant issues a work order through a PaaS platform portal, the component console accepts and processes the work order, and then calls the underlying Agent proxy service to implement construction operations such as creation or deregistration of specific instance nodes.

[0044] In addition, in the construction operation, the construction processing logic based on the finite state machine is mainly implemented by the component console backend service, and MySQL and Zookeeper are used to respectively implement the storage of state sets and state context information and the triggering and scheduling of construction flow. The specific whole architecture interaction diagram is shown in the figure. Figure 2as shown.

[0045] The construction operation includes:

[0046] In step S102, the component console completes work order information processing based on the work order information to obtain a processing result. The work order information processing includes: analyzing work order format, checking work order parameters, determining construction type, and saving data information.

[0047] Specifically, after the component console receives the construction order issued by the PaaS, the component console completes work order information processing based on the work order information. The work order information processing includes: analyzing work order format, checking work order parameters, determining construction type, and saving data information, to obtain a processing result. In addition, the component console can also synchronously respond to the PaaS platform with the work order information processing, so that the PaaS platform displays the construction order state as “under construction”.

[0048] In step S103, the component console deploys the underlying Agent agent service to the underlying tenant VPC area, and performs asynchronous construction in the tenant VPC area based on the processing result. The asynchronous construction is triggered by registering a node on the Zookeeper, and includes: determining the construction type according to the processing result, and then determining the corresponding state set and state transition as the action set of the asynchronous construction.

[0049] Specifically, the component console deploys the Agent agent service to the underlying VPC area resource host, for the operation and deployment of the underlying instance resources. The component console sequentially executes subsequent asynchronous construction operations in the tenant VPC area based on the state machine. The component console registers a node on the Zookeeper to trigger the asynchronous construction process based on the state machine. The asynchronous construction operation is based on the finite state machine mode. From the original state, the asynchronous construction operation is converted to the initialization ready state through the environment initialization action. Then, the asynchronous construction operation executes node creation or cluster shard creation according to different instance types. In addition, the asynchronous construction operation corresponds to the code implementation level, which is each operation class or operation function interface. The state transitions that overlap with each other in the creation process can be reused, which reduces the coupling of code implementation, and enhances the extensibility and maintainability.

[0050] In addition, the asynchronous construction operation can include the steps of host environment initialization, instance node creation according to a processing result, node relationship establishment, configuration of a unified access layer, and in the instance node creation according to the processing result, specifically including: for single machine, primary and backup and read-only version instances, single, twice and multiple node creation actions are respectively required to be performed to realize the conversion from the environment initialization ready state to the instance node ready state, and then the configuration of the primary and backup relationship action is performed; for the cluster version instance, multiple creation shard actions are required to be performed to realize the conversion from the environment initialization ready state to the shard ready state, and each shard is equivalent to a primary and backup instance, so the creation of each shard is equivalent to the execution of the process of creating a primary and backup node and establishing a primary and backup relationship, and multiple shards execute multiple creation processes, and then the creation of a cluster agent node action is performed.

[0051] In addition, the component console of the resource pre-provisioning area and the Agent agent service initialized and deployed on the resource host of the tenant VPC area communicate and interact through the grpc protocol, avoiding the coding complexity of ssh protocol interaction, and enhancing the communication security.

[0052] Step S104, after the asynchronous construction is completed, the construction result is fed back to the component console, and the construction state is updated to the PaaS platform through the construction result.

[0053] Specifically, after the asynchronous construction is completed, the construction result is fed back to the component console, and the construction state is updated to the PaaS platform through the construction result, so that the display of the construction state is updated to “construction success”, and thus the instance opening construction is successfully completed and the tenant can be provided with services. In addition, if any link before the asynchronous construction such as ticket analysis and parameter verification is wrong, the synchronous response result is directly returned as failure, and the asynchronous construction process will not be triggered; if any state conversion action in the asynchronous construction process is wrong, the construction response result is asynchronously returned as failure in the current state, because the context of each state is stored in the MySQL, so after the problem is repaired, the corresponding construction flow of the ticket is triggered to continue to be executed by re-registering the Zookeeper node.

[0054] In addition, in the asynchronous construction process, the history state of the construction flow of the ticket information is recorded through the MySQL storage system (if it is a new ticket, the history state is EMPTY, i.e. the original state), which can realize the triggering and execution from the initial or intermediate state machine action, so that the finite state set corresponding to each construction type, the current construction state and the context information are maintained through the MySQL, which can realize the idempotent and continuation operation of the construction interruption, retry and other process processing, avoid the rollback or repeated operation of the executed operation, improve the construction efficiency and enhance the robustness of the ticket processing.

[0055] The example timing diagram of the construction operation in the embodiment can be as followsFigure 3 As shown, the component console initiates an asynchronous construction process after receiving the work order analysis and verification, first deploying the Agent agent service to the underlying VPC zone resource host during environment initialization for the operation and deployment of the underlying instance resources, then sequentially executing subsequent construction operations by the component console based on the state machine, and communicating between the resource pre-provisioning zone and the tenant VPC zone through grpc; finally, the asynchronous single response is executed to the PaaS platform after the construction is completed, the construction state is updated, and the product instance is delivered to the tenant.

[0056] The embodiment of the application provides a cloud cache database construction processing method based on a finite state machine, a component console receives work order information issued by a tenant through a PaaS platform, and determines corresponding construction operations according to the work order information, and calls an underlying Agent agent service to implement the construction operations; the construction operations include that the component console completes work order information processing based on the work order information to obtain a processing result, and the work order information processing includes analyzing a work order format, verifying work order parameters, judging a construction type, and saving data information; the component console deploys the underlying Agent agent service to a tenant VPC zone in the underlying layer, and performs asynchronous construction in the tenant VPC zone based on the processing result, and the asynchronous construction is triggered by registering a node on Zookeeper, including determining a construction type according to the processing result, and then determining a corresponding state set and a state transition action set for asynchronous construction; after the asynchronous construction is completed, the construction result is fed back to the component console, and the construction state is updated to the PaaS platform through the construction result. Advantages and improvements include: 1, different types of construction operations of different versions of instances are step-split and mapped with the state machine, the granularity of each construction step is refined, corresponding coding is implemented for the conversion actions between different states, the construction operation is accurate and controllable, the same construction actions in different construction processes can realize code reuse, which is convenient for development and implementation and also convenient for later maintenance, greatly enhancing the simplicity and expansibility of coding; 2, the node registration on Zookeeper is used to trigger and start the construction state flow task, greatly improving the autonomy and convenience of construction process scheduling.
