Description

Method for synchronizing resource states among cloud service heterogeneous subsystems
Technical Field
The invention belongs to the field of cloud computing, and particularly relates to a method for synchronizing resource states among cloud service heterogeneous subsystems.
Background
Cloud computing is to server resources such as computation, network, storage and the like, and provides a distributed computing mode of different resources according to requirements of different tenants and users. With the development of technology, more and more enterprises and individuals nowadays start to purchase and use cloud computing services due to the excessive cost of purchasing hardware resources, and the public cloud market is growing rapidly.
In order to provide more resources and computing power for more tenants and users and improve stability of resources and security of user data, most common cloud manufacturers at home and abroad mostly adopt to deploy a plurality of data centers in different regions to provide resource services for the tenants and users respectively. However, for tenants and users, the resources purchased in all regions need to be seen for convenient management, and a service needs to be provided to collect the resource information of all region services, which brings a problem about how to synchronize the states of the resources in the subsystems of the cloud service architecture.
The existing synchronization scheme between heterogeneous systems is roughly divided into two types, one is a message middleware MQ, and when data of a data changing party changes, a data receiving party is informed to update the changed data through a queue; and the other is to provide an API interface between heterogeneous systems, and directly call the API interface to update data when the data changes. Both of these solutions suffer from drawbacks: the MQ is used for data synchronization, and depending on network states among heterogeneous systems, the MQ has high requirements on network stability and also has the risk of losing messages, and if the messages are lost, the risk that the data can not be automatically synchronized forever can exist; synchronization through the API interface may have cyclic dependencies between two heterogeneous systems and increase the coupling between heterogeneous systems with poor performance and concurrency support.

b1, a user inquires the resource state through a UI interface or an openapi, and a resource-server in an operation management layer service cluster receives a request;
b2, after receiving the request, the resource-server in the operation management layer service cluster directly acquires the state information from the local library instance table and returns the state information;
b3, after receiving the request, judging whether the redis cache has synchronous records or not, and if the synchronous records do not have the state of asynchronously calling the resource-server synchronous resources in the resource management layer service cluster; the life cycle of synchronous record in the redis cache is 15s;
b4, scheduling service in the operation management layer service cluster regularly calls resource-server in the resource management layer service cluster to synchronize the states of all resources;
in step A1, the transaction-server service in the operation management layer service cluster is mainly responsible for operations related to user transactions, such as order placing, order returning, and the like.
In step A2, resource-server service in the operation management layer service cluster is mainly responsible for resource management, including operations such as resource list, resource details and the like; the operation management layer service cluster manages a plurality of resource management layer service clusters, and integrates resource information of users distributed on a plurality of resource modules.
In step A2, a database instance table in the service cluster of the operation management layer mainly stores the basic information of resources of all users distributed in all resource modules; the id column in the Instance table is the table primary key; the instance_id column is the resource id; order_id is the id of the user's order, allowing multiple resources to be created in one order, i.e., order_id and instance_id are one-to-many relationships; status represents the status of the resource; opt_status represents the operational status of a resource, and because the same order may create multiple resources, theoretically resources in one order are uniformly delivered, the opt_status of all resources in the same order are uniform.
In step A3, resource-server service in the resource management layer service cluster is mainly responsible for resource management, including operations such as resource list, resource details and the like; each resource module corresponds to a resource management layer service cluster.

In step A5, the schedule scheduling service in the service cluster of the operation management layer is mainly responsible for the scheduling task of the operation management layer, and the schedule scheduling service sends a request to each service cluster of the resource management layer every 30 seconds, and obtains the states of all the resources in the creation and updates the local library according to the states in the instance table; the schedule dispatch service judges whether the opt_status is all resources of the same order_id in the creation process or not according to the opt_status and order_id in the instance table every 30 seconds, updates the opt_status state if the creation is successful or not, notifies the transaction-server service to pay back if the creation is failed, and updates the opt_status to the creation failure if the creation is failed.
In step B2, after receiving the request, the resource-server service in the operation management layer service cluster directly acquires the state information from the local library and returns the state information; the returned state is determined according to status and opt_status, if opt_status is in creation, the returned state is in creation; if opt_status is running, returning to status state; if opt_status is a creation failure, then a creation failure is returned.
In step B3, the redis-server service in the operation management layer service cluster is used for caching distributed data; the record of the synchronous state in the redis cache has a life cycle of 15s, namely if the user frequently acquires the request of the resource state in 15s, the resource management layer is only needed to acquire once and update the local library, so that the response speed is improved and the concurrence is improved.
In step B4, the schedule scheduling service in the service clusters of the management layer is operated, and each resource management layer service cluster is sent to obtain the specified resource state every hour, so as to avoid the situation that the long-time resource state is inconsistent due to the fact that the user does not manually operate to obtain the instance state for a long time.
