It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The embodiments will now be described in detail with reference to the accompanying drawings.

[0035] Kubernetes is a leading distributed architecture solution based on container technology. Building upon Docker, it provides containerized applications with a range of functionalities including deployment, operation, resource scheduling, service discovery, and dynamic scaling, improving the convenience and high availability of large-scale container cluster management. Kubernetes relies on a robust network, so its cluster deployment is typically confined to a single data center. For Kubernetes clusters spanning multiple data centers, a multi-cluster management model is commonly used. This involves building independent Kubernetes clusters within their respective data centers and then using multi-cluster management tools to manage cluster services. Examples of such multi-cluster solutions include KubeFed (cluster federation) and Karmada.

[0036] However, the applicant discovered that existing multi-cluster management solutions have the following problems: 1. Each data center needs to build a complete Kubernetes cluster, resulting in a management plane resource consumption of 5 nodes (servers) (3 master nodes + 2 load balancer nodes) while ensuring high availability. 2. There is a lack of flexible resource management; each data center is an independent cluster, and they do not interfere with each other, making cross-center service scheduling and management impossible. 3. Each cluster is maintained independently. To achieve inter-cluster collaboration, a multi-cluster management platform, such as KubeFed (cluster federation) or Karmada, needs to be built on top of the Kubernetes cluster, introducing more cluster management burden.

[0037] Therefore, for star-shaped data centers, where the core data center has a large number of servers and other data centers have a small number of servers, this application provides a data processing method that enables data centers with a small number of servers to directly access the cluster within the core data center as nodes. This solves the Kubernetes single cluster's dependence on a good network, enables unified management of servers in the core data center and servers in other data centers, and realizes three cloud-edge collaboration capabilities: management collaboration, data collaboration, and operation and maintenance collaboration between the core data center and other data centers. While ensuring that the cluster can stably provide services, it expands the scope of Kubernetes single cluster management.

[0038] To address the problems of the prior art, embodiments of this application provide a data processing method, apparatus, device, storage medium, and program product. The data processing method provided in this application embodiment will be described first below.

[0039] Figure 1 A flowchart illustrating a data processing method according to an embodiment of this application is shown. The method is applied to an edge server (first edge server) and includes the following steps S101 to S103:

[0040] S101, receive the first service request sent by the user terminal.

[0041] S102, when the connection between the first edge node device and the cloud server is broken, the first response data corresponding to the first service request is searched in the cache database of the first edge node device, and the first response data is sent to the user terminal.

[0042] The first service request is a service request initiated by the user terminal for data in the cloud server.

[0043] Specifically, after receiving a service request from a user terminal, it is necessary to first determine the current communication connection status between the first edge node and the cloud server. If the connection between the first edge node device and the cloud server is broken, it means that the first service request cannot be forwarded to the cloud server for processing. In order to ensure the timely processing of the first service request, the response data corresponding to the first service can be found in the cache database of the first edge node device. Then, the first service request is processed according to the response data corresponding to the first service, and the first response data is sent to the user terminal.

[0044] S103, when the first edge node device is connected to the cloud server, sends a first service request to the cloud server, and sends the response data received from the cloud server to the user terminal and stores it in the cache database.

[0045] The response data is the data determined by the cloud server that corresponds to the first business request.

[0046] Specifically, when the first edge node device and the cloud server are connected, the first edge node device can forward the first business request to the cloud server. After the cloud server processes the request, it returns the second response data corresponding to the first business request. The first edge node device receives the second response data returned by the cloud server and caches it in its local database. This allows it to process business requests normally by using the data in the cached database even if the connection between the first edge node device and the cloud server is lost, thus achieving edge autonomy.

[0047] In some embodiments, steps S101 to S103 can be performed using a CNI (Container Network Interface) plugin.

[0048] In some embodiments, steps S101 to S103 can also be based on HTTP reverse proxy technology for caching critical data, using the cache to provide offline autonomous capabilities for critical Kubernetes services. However, it can also be implemented in other ways, and this application embodiment does not limit this.

[0049] In this embodiment, a data processing method is proposed, which receives a first service request sent by a user terminal; when the connection between the first edge node device and the cloud server is broken, the service request that is to be processed by the cloud server is processed by the first edge node device through cached data; when the connection between the first edge node device and the cloud server is restored, the service request is forwarded to the cloud server for processing, and the response data returned by the cloud server is received and cached in the database. This enables edge autonomy when the first edge node device and the cloud server are broken, and maintains the stability of the service provided by the edge node device.

[0050] In some embodiments, after S101, that is, after receiving the first service request sent by the user terminal, the method may further include:

[0051] When the first edge node device and the cloud server are in a connected state, the first edge node device forwards the first business request to the cloud server through the reverse proxy component;

[0052] The reverse proxy component receives the second response data of the first business request returned by the cloud server.

[0053] The second response data is cached in the business processing component of the first edge node device.

[0054] Specifically, the first edge node device can use a reverse proxy component to receive the first service request sent by the user terminal. When the first edge node device is connected to the cloud server, the first service request is proxied to the edge server for processing. When the reverse proxy component receives the second response data corresponding to the first service, it sends the second response data to the user terminal and caches the second response data in the local cache database. In this way, even when the first edge node device is disconnected from the cloud server, the first service request can be proxied to the service processing component of the first edge node device for processing. This ensures that the services in the first edge node device can be processed normally even when the connection between the first edge node device and the cloud server is lost, thus achieving edge autonomy.

[0055] In one example, the cloud server and edge node devices experience a network outage. To achieve autonomy for edge services and ensure that service instances are not affected by network fluctuations, especially to ensure that service instances can still be successfully restarted even if an edge node crashes and restarts after a network outage with the cloud server, this can be achieved through a remote service (API Server) on the cloud server, and a proxy service (EdgeProxy) and client on the edge node devices. The specific steps are as follows:

[0056] 1) Client requests to the Kubernetes API Server pass through the EdgeProxy edge node.

[0057] 2) EdgeProxy determines whether the remote API Server is reachable from the network. If it is reachable, proceed to step 3; otherwise, proceed to step 6.

[0058] 3) EdgeProxy forwards the request to the real API Server (i.e., forwards the first business request to the cloud server through the reverse proxy component).

[0059] 4) The real API Server responds to the client's request and returns the response data to EdgeProxy. EdgeProxy intercepts the data in the request response body (i.e., the second response data of the first business request returned by the cloud server through the reverse proxy component), copies the data stream twice, encodes and decodes one data stream and stores it on the local disk, and sends the other response to the client, thus ending the process.

[0060] 5) When the network is unreachable, EdgeProxy will forward the request to local processing.

[0061] 6) EdgeProxy reads local cached data, constructs the response body, and responds to the client.

[0062] In some embodiments, the first edge node device may cache response data to the first edge node device when it receives the second response data of the first business request returned by the cloud server through a reverse proxy component.

[0063] In one example, the network snapshot feature can be used to achieve edge node autonomy when the first edge node device loses connection with the cloud server. This primarily involves non-intrusively adding snapshot functionality to the IPAM CNI plugin. After a specified check fails, snapshot data can be used to assign IPs to containers; upon successful check, the actual IPAM is invoked for processing. This adds network snapshot functionality to cloud-edge scenarios, providing offline autonomous network IP allocation capabilities.

[0064] The specific steps are as follows:

[0065] 1) By configuring the system, the IPAM call is intercepted and delegated to snapshot-ipam, which has snapshot logic, to make the IPAM call.

[0066] 2) When snapshot-ipam intercepts the ADD method call, it performs a check. If the check passes, it calls the actual IPAM to allocate an IP address and records the result in the snapshotPath directory with the filename: {pod namespace}_{pod name}, containing the actual IPAM return value. If the actual IPAM encounters an error, it directly returns an exception. If there is no record locally and the check fails, it directly returns an exception.

[0067] 3) When snapshot-ipam intercepts the DEL method call, it performs a check. If the check passes, it calls the actual IPam to reclaim the IP, and then deletes the corresponding file under snapshotPath.

[0068] To avoid a surge in traffic to the cloud server during the restoration of connectivity to multiple edge node devices in various regions from a disconnected state, some embodiments may further include, after S101 (i.e., after receiving the first service request from the user terminal):

[0069] When the first edge node device and the cloud server are restored from a disconnected state to a connected state and a second service request is received, a service restoration request is sent to the cloud server.

[0070] The system receives communication permission information returned by the cloud server. This communication permission information is used to indicate the business permission status between multiple edge node devices in the target area and the cloud server. The multiple edge node devices include the first edge node device. The business permission status is used to indicate whether the cloud server allows receiving business requests sent by multiple edge node devices.

[0071] If the business license status indicates that the cloud server is allowed to receive business requests from multiple edge node devices, a second business request is sent to the cloud server.

[0072] Specifically, when the first edge node device recovers from a disconnected state to a connected state and receives a second service request, it indicates that the first edge node device has restored its network connection with the cloud server and can resume services interrupted due to network issues. First, it needs to initiate a service recovery request to the cloud server to obtain communication permission information from the cloud device for the first edge node device, determining whether the first edge node device can resume service communication with the cloud device. If the service permission status indicates that the cloud server allows receiving service requests from multiple edge node devices, it means that no other edge node devices in other regions are currently restoring service connections with the cloud server, and thus the second service request can be sent to the cloud server. If the service permission status indicates that the cloud server does not allow receiving service requests from multiple edge node devices, it means that edge node devices in other regions are currently restoring service connections with the cloud server. Therefore, to avoid traffic congestion on the cloud server, sending the second service request to the cloud server is prohibited, and the second service request is proxied to the first edge node device for processing through a reverse proxy.

[0073] Figure 2 A flowchart illustrating a data processing method according to another embodiment of this application is shown. The method is applied to a cloud server and includes the following steps S201 to S203:

[0074] S201, when the first edge node device is connected to the cloud server, receive the first service request sent by the edge node device;

[0075] S202, in response to the first service request, determine the second response data corresponding to the first service request;

[0076] S203, send the second response data to the first edge node device.

[0077] The first edge node device is used to send the received second response data to the user terminal and store it in the cache database. The cache database is used to provide response data corresponding to the third service request when the first edge node device is in a disconnected state with the cloud server and receives a third service request. The third service request includes the first service request.

[0078] Specifically, the cloud server receives a first service request from a first edge node, retrieves the response data (second response data) related to the first service request based on its content, and then sends the second response data to the first edge node device. This enables the first edge node device to send the received second response data to the user terminal and store it in a cache database. The cache database is used to provide response data corresponding to a third service request, which includes the first service request, when the first edge node device is disconnected from the cloud server and receives a third service request. This allows the edge node device to be directly incorporated into the cluster of the cloud server for unified management, enabling the first edge node device to maintain stable edge service operations and expanding the application scenarios of Kubernetes.

[0079] In some embodiments, before step S201 above, that is, before receiving the first service request sent by the edge node device when the first edge node device and the cloud server are in a connected state, the following may also be included:

[0080] When the connection between the first edge node device and the cloud server is restored from a disconnected state to a connected state, the service restoration request sent by the first edge node device is received.

[0081] According to the service recovery request, the communication license information of the first region to which the first edge node device belongs is sent to the first edge node device. The communication license information is used to indicate the service license status of multiple edge node devices in the first region with the cloud server. The multiple edge node devices include the first edge node device. The service license status is used to indicate whether the cloud server allows receiving service requests sent by multiple edge node devices.

[0082] Specifically, in this embodiment, edge node devices within a preset area are grouped together for management. When the first edge node device is connected to the cloud server, it communicates directly with the cloud server. When the connection is lost, the first edge node device performs edge autonomy. When the connection is restored, the system obtains communication permission from the cloud server for the preset area (i.e., the first area) to which the first edge node device belongs to determine whether business communication with the cloud server can be resumed. Thus, in the case of multiple preset areas, communication permission prevents edge node devices in multiple areas from simultaneously resuming business connections with the cloud server, avoiding traffic congestion and achieving traffic control.

[0083] In some embodiments, after sending the communication license information of the first region to which the first edge node device belongs to the first edge node device according to the service recovery request, the method may further include:

[0084] If the business license status in the communication license information is that it allows receiving business requests sent by multiple edge node devices in the first area, the recovery time of the first edge node device is obtained. The recovery time is the time required for the first edge node device to resume business data communication with the cloud server.

[0085] Based on the recovery time, the communication license information for the second region is updated to prohibit receiving service requests sent by multiple edge node devices within the second region. The coverage area of ​​the second region is different from that of the first region.

[0086] In one example, traffic management can be used to prevent cloud servers from experiencing traffic surges. Traffic management primarily addresses the issue of edge nodes re-establishing network connections with the cloud server after edge network instability. This requires retrieving all data, which can significantly impact the cloud server's API server management component. Therefore, to reduce the traffic impact on the cloud server's API server, traffic management is implemented through the following steps: Access to the Kubernetes API Server via the EdgeProxy can be controlled using a permission-based system. Access to the API Server by the edge nodes is restored in batches by controlling permission expiration.

[0087] The specific steps are as follows:

[0088] 1) When the fault isolation controller detects a network fault within the area, it updates the access attribute of the area's permissions to false.

[0089] 2) Continuously check the region until a node recovers to normal. At this point, set the access attribute of the region to true and set time to max(current time, maximum value of all permitted time fields + recovery time interval).

[0090] 3) Before each access to the API Server, EdgeProxy obtains permission and confirms whether the access is true and the current time is greater than the time allowed in the region. If the conditions are met, the request is forwarded to the remote API Server; otherwise, the request is handled locally.

[0091] In some embodiments, before receiving the reconnection request from the first edge node device when the first edge node device and the cloud server are in a connected state, the method further includes:

[0092] Obtain the heartbeat data of the first edge node device;

[0093] If the heartbeat data does not meet the preset conditions, obtain the heartbeat data of the second edge node device in the first region. The second edge node device is any other edge node device in the first region other than the first edge node device.

[0094] If the heartbeat data of the second edge node device meets the preset conditions, it is determined that the first edge node device has failed.

[0095] The services in the first edge node device are migrated to the second edge node device, which is closest to the first edge node device, for processing.

[0096] In one example, within a distributed data center scenario, the network within a single data center is stable and reliable, while the network quality across data centers is unstable. Area probing technology can be used to accurately identify whether a node failure is a genuine malfunction or a communication error caused by an unstable, weak network environment. In this application, this can be achieved by setting up a fault isolation system on a cloud server. This fault isolation system is a self-developed container cloud fault detection and service eviction system, primarily used to quickly handle node failures.

[0097] The specific steps are as follows:

[0098] 1) The fault isolation controller detected that the fault isolation agent did not report a heartbeat.

[0099] 2) The fault isolation controller performs a ping test on the node. If the node can be pinged, the node is considered to be normal and the process ends; otherwise, continue to the next step.

[0100] 3) Check if the node has a region identifier. If not, determine that the node is abnormal within the data center and directly evict it.

[0101] 4) The controller obtains nodes in the same region within the cluster, and then performs ping tests on the nodes in the region. If other nodes in the region can be pinged, it is determined that the edge node is faulty, and node isolation operation is performed (that is, the services in the first edge node device are migrated to the second edge node device closest to the first edge node device for processing). Otherwise, it is determined that the edge network is faulty (that is, the edge node device is disconnected from the cloud server), and the process ends.
