[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0026] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between two items, or an association relationship between the two items, or a relationship between indication and being indicated, configuration and being configured, and the like.

[0027] Figure 1 A cloud service system according to an embodiment of the present invention. Figure 1 As shown, the cloud service system is provided with a cloud service resource association model, which includes a hardware resource layer, a virtualized resource pool layer, a cloud service layer, and an application layer;

[0028] The hardware resource layer includes callable hardware resources; the virtualized resource pool layer includes callable virtualized resources; the virtualized resource pool layer includes several units; each unit includes at least two groups of resource nodes; at least two groups of resource nodes in each unit are in different availability zones / fault tolerance domains;

[0029] The cloud service layer is used to deploy corresponding cloud services on several units; the cloud service includes at least one between a database and a container; the application layer is used to run corresponding applications according to each cloud service and set master and slave nodes in the units of the cloud service.

[0030] The hardware resource layer is the first layer of the cloud service system, including available hardware resources, such as physical machines, switches, etc. Hardware resources are the physical basis for the operation of the cloud service system.

[0031] The virtualized resource pool layer is the second layer of the cloud service system, including callable virtualized resources, such as virtual machines, virtual networks, VPNs and other IaaS resources. The virtualized resource pool layer uses virtualization technology and other means to create and manage resources, corresponding to the physical resources of the first layer. This layer is further divided into several units, each of which contains at least two groups of resource nodes, which are resource application or resource scheduling units. These two groups of resource nodes are distributed in different availability zones or fault tolerance domains to improve the fault tolerance and availability of the system.

[0032] The cloud service layer is the third layer of the cloud service system, which is used to deploy corresponding cloud services on several units. Cloud services include PaaS cloud services such as databases (such as MySQL), containers (such as Docker), and message queues (such as Redis). It runs on the IaaS resources provided by the virtualized resource pool layer. When deploying cloud services, the unit is not the unit of individual resource nodes, but the minimum resource scheduling unit. Optionally, based on the unit setting, when the cloud service layer is expanded or an underlying failure occurs, it is necessary to add or replace resource nodes, which can ensure that high availability requirements are still met after expansion or replacement of nodes. The cloud service layer does not need to care about the specific deployment of resource nodes in the unit. It only needs to know the disaster recovery level of the unit to build cloud services of the corresponding disaster recovery level, which simplifies the design of disaster recovery for underlying resources for various services.

[0033] The application layer is the fourth layer of the cloud service system, which is used to run actual business applications based on various cloud services to generate business value. The key factors affecting system availability, such as databases and message queues, are deployed using a master-slave architecture. The system will set up master and slave nodes according to the units of the cloud service to improve the availability of the system.

[0034] The system provided by the present invention builds a high-availability system in a cloud environment through a four-level resource association model. The model improves the availability of the system through virtualization technology, unit division, and master-slave architecture.

[0035] In an optional implementation, the virtualized resource pool layer further includes a resource creation interface; the resource creation interface is used to select a unit according to a specified resource pool, fault domain, or availability zone.

[0036] In the virtualized resource pool layer, a resource creation interface is also provided to provide a mechanism that allows units to be selected based on a specified resource pool, fault domain, or availability zone.

[0037] The resource creation interface provides the ability to specify parameters such as resource pools, fault domains, and availability zones. Alternatively, it provides availability sets to ensure that the created resources are evenly distributed in different fault domains, so as to maximize the selection of units and improve creation efficiency. At the same time, it ensures the correctness of resource tags and synchronizes them to the cloud service layer in a timely manner after changes occur, so as to facilitate unit replacement or data migration.

[0038] In an optional implementation, the virtualized resource pool layer is further configured to synchronize the change information to the cloud service layer when detecting a change in the state of a resource node in a unit, so that the cloud service layer reselects the unit.

[0039] In the cloud service system, the status of resource nodes may change due to various reasons, such as hardware failure, network problems, maintenance and upgrades, etc. The virtualized resource pool layer can detect these status changes in real time through the built-in monitoring mechanism or integration with the external monitoring system. Upon detecting the status change of the resource node, the virtualized resource pool layer synchronizes the relevant change information to the cloud service layer. The change information may include the current status of the resource node, the type of failure, the estimated recovery time, etc. Synchronizing the change information to the cloud service layer enables the cloud service layer to understand the latest status of the resource node in a timely manner, adjust the service deployment strategy as needed, and reselect the unit.

[0040] The cloud service layer can determine the logic of selecting units according to its own characteristics, which has a certain degree of flexibility. After the cloud service layer completes the selection of units and deployment, the selection results should be synchronized back to the virtualized resource pool layer. This can avoid migrating resources under the same unit to the same fault-tolerance domain during daily migration and maintenance, which will destroy the highly available master-slave architecture. Some IaaS bases have the ability to automatically drift due to faults. In order to avoid the impact of drift, a daily inspection mechanism needs to be formed to check whether there are nodes that no longer meet the requirements after drift. Establish a communication and maintenance mechanism for the unit, provide migration target constraints when performing resource migration at the virtualized resource pool layer, and perceive the cloud service layer's requirements for resource distribution. The inspection mechanism ensures that the resources under the unit can be distributed as expected.

[0041] Figure 2It is a schematic diagram of the structural relationship of the PaaS service after adding units according to an embodiment of the present invention. As an infrastructure, the PaaS service layer (i.e., the cloud service layer) provides a stable and reliable operating environment for application A and application B, and supports the deployment, management, and expansion of applications. Application A and application B are deployed in unit1 and unit2, respectively, and each application contains multiple virtual machine instances to achieve load balancing and high availability. Application A and application B each have independent fault tolerance domains, and each fault tolerance domain consists of virtual machines located in different physical locations. Application A and application B are deployed in different availability zones, respectively. If multiple virtual machines in a certain availability zone fail at the same time, the virtual machines in another availability zone can still run, which improves the fault tolerance of the system. Through cross-fault-tolerance domain and cross-availability zone disaster recovery, the continuous operation of the system in various failure scenarios is ensured.

[0042] According to an embodiment of the present invention, an embodiment of a cloud service resource management method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0043] In this embodiment, a cloud service resource management method is provided. Figure 3 is a flow chart of a cloud service resource management method according to an embodiment of the present invention. Figure 3 As shown, the method is applied to a cloud service system, and the process includes the following steps:

[0044] Step S101, constructing a hardware resource layer in a cloud service resource association model, and setting a hardware resource tag; the hardware resource tag is used to indicate the availability zone and hardware information corresponding to the hardware resource.

[0045] To build a cloud service resource association model, first, you need to establish a hardware resource layer, which contains the underlying hardware resources that the cloud service system relies on, such as physical machines, switches, etc. Set corresponding tags for hardware resources to indicate the key attributes of hardware resources. Resource tags include resource pool guarantee level, availability zone, hardware information, specifications, etc. By setting tags for hardware resources, you can easily manage and schedule these resources.

[0046] Step S102, constructing a virtualized resource pool layer in a cloud service resource association model, and setting virtual resource tags; the virtual resource tags are used to indicate the actual running physical machine and fault tolerance domain of the resource node.

[0047] Similar to the hardware resource layer, tags are set for virtualized resources to indicate the key attributes of virtualized resources. Virtual resource tags include actual running physical machines, fault tolerance domains, and security levels. Build resource pools with different security levels, establish the capacity and practicality of each resource pool, provide recommendations when creating resources for the virtualized resource pool layer, promptly disable new resources in resource pools with high loads, and reserve some redundancy for emergency resource creation and resource replacement in case of failures. By setting tags for virtualized resources, you can more accurately control the deployment and migration of resources to meet different business needs.

[0048] Step S103: divide at least two groups of resource nodes distributed in different availability zones in the virtualized resource pool layer into one unit, and select at least one unit to deploy cloud services of the cloud service layer.

[0049] The resource nodes distributed in different availability zones in the virtualized resource pool layer are divided and combined into units. Each unit contains at least two groups of resource nodes distributed in different availability zones to ensure that the service can still run normally when a single availability zone fails. Select at least one of these units to deploy the cloud service of the cloud service layer. By dividing the resource nodes into units and selecting units to deploy cloud services, the availability and stability of the cloud service system can be improved.

[0050] In summary, the cloud service resource management method provided in this embodiment improves the high availability of the cloud service system by constructing a cloud service resource association model and adopting a unitized resource deployment strategy.

[0051] In an optional embodiment, the method further includes:

[0052] When the cloud service is expanded or an underlying failure occurs, at least one available unit is selected in the virtualized resource pool layer to perform node expansion or node replacement.

[0053] As the business develops, the cloud service system may need to bear more loads and expand its nodes to increase the system's processing capacity. At the same time, due to underlying failures, some nodes in the cloud service system may fail and need to be replaced to restore the normal operation of the system.

[0054] In the virtualized resource pool layer, resource nodes distributed in different availability zones are divided into multiple units. When you need to expand or replace a node, select an available unit in the virtualized resource pool layer. When selecting a unit, consider the unit's disaster tolerance level. When expanding or replacing a node, give priority to units with higher disaster tolerance levels.

[0055] This implementation ensures the continuous and stable operation of the cloud service system in the event of expansion or failure by expanding or replacing nodes.

[0056] In an optional implementation, the above step S103 includes the following steps:

[0057] Step a11, obtaining the disaster recovery level of the cloud service of the cloud service layer.

[0058] First, determine the disaster tolerance level of each cloud service in the cloud service layer. The disaster tolerance level is determined based on the distribution of resource nodes in the unit and the fault tolerance capability. By querying the configuration information or metadata of the cloud service layer, the disaster tolerance level of each cloud service can be obtained.

[0059] Step a12: selecting at least one unit from each unit to deploy cloud services of the cloud service layer according to the disaster recovery level.

[0060] After obtaining the disaster recovery level of the cloud service, a suitable unit is selected from each unit in the virtualized resource pool layer to deploy the cloud service. The selection process is based on the disaster recovery level of the cloud service and the disaster recovery capability of each unit.

[0061] The disaster recovery capability of each unit is evaluated based on factors such as the distribution of resource nodes in the unit, the number of fault tolerance domains, the number of availability zones, and the interconnectivity between units. The more disaster-tolerant a unit is, the more extensive its internal resource nodes are, and the more fault-tolerant it is, which can better meet the deployment requirements of cloud services with high disaster recovery levels.

[0062] Based on the disaster recovery level of the cloud service and the disaster recovery capabilities of each unit, the system selects at least one suitable unit to deploy the cloud service. Units whose disaster recovery capabilities meet or exceed the disaster recovery level of the cloud service are given priority to ensure that the cloud service can obtain sufficient disaster recovery protection after deployment.

[0063] This implementation manner deploys cloud services by selecting units based on the disaster recovery level, thereby ensuring that the cloud services can obtain disaster recovery guarantees that match their disaster recovery levels after deployment.

[0064] The following is an optional embodiment of the present invention:

[0065] Taking the construction of a cross-availability zone application system as an example, we build the architecture model of resources at each level. The following steps are followed when building services at the cloud service layer:

[0066] Two groups of resource nodes distributed in different availability zones are pre-defined as the same unit. Each group of units is labeled with the number of availability zones. When the PaaS service is actually deployed, several groups of units are selected for deployment to provide services.

[0067] When the PaaS service is expanded or an underlying failure occurs, it is necessary to add or replace nodes. At this time, the unit is still used as the minimum resource scheduling unit, and the unit group with the number of available zones in the label greater than 1 is selected to ensure that the high availability requirements are still met after expansion or replacement of nodes.

[0068] The virtualized resource pool layer provides availability set capabilities when creating resources, ensuring that the created resources are evenly distributed in different fault tolerance domains, so as to maximize the selection of units and improve creation efficiency. At the same time, the correctness of resource tags is guaranteed, and they are synchronized to the cloud service layer in a timely manner after changes occur, so as to facilitate unit replacement or data migration.

[0069] PaaS services can determine the logic of selecting units based on their own characteristics, which has a certain degree of flexibility. After the cloud service layer completes the selection of units and deployment, the selection results should be synchronized back to the virtualized resource pool layer. This can avoid migrating resources under the same unit to the same fault-tolerant domain during daily migration and maintenance, thereby destroying the highly available master-slave architecture. Some IaaS bases have the ability to automatically drift faults. In order to avoid the impact of drift, a daily inspection mechanism needs to be formed to check whether there are nodes that no longer meet the requirements after drift.
