Background

With the deep concept of cloud primordia, micro services are increasingly applied to actual work in large fist stretching of various large enterprises, such as decoupling of computation and storage, stateless and stateful separation, and the like.

Under the condition that cloud primary storm is rolled up, besides focusing on the application itself, configuration management is becoming more and more important, in applications such as electronic commerce, games and social contact, the method of decoupling the application and the configuration is basically adopted after micro-service, the binding of the configuration and the application is reduced, the configuration is processed more statically, and developers are more in development of the application. However, the configuration is the basis of the running of the application, and once the failure occurs, the stability of the running of the application is directly caused, and the service is interrupted for users, so that the user loss, economic loss, reputation damage and the like are caused. Configuration management is therefore particularly important in a cloud-native environment.

However, since the application and configuration are decoupled after micro-servings, the configuration files may be dispersed among different services, which may lead to consistency problems of the configuration. If different service uses different configuration files or the configuration files are updated untimely, inconsistency among the services can be caused, and the stability and performance of the application can be affected.

Referring to fig. 1, an embodiment of the present invention provides a method for cloud synchronization based on Nacos configuration management, where the method specifically includes:

S101, acquiring a plurality of cloud servers, and respectively arranging Nacos clusters on each cloud server;

S102, enabling each cloud server to be connected with at least one client respectively;

And S103, enabling each Nacos cluster to be connected with the same Nacos database at the same time, setting the local cache time interval of each Nacos cluster to be a preset time, wherein the preset time is the shortest time interval of the local cache of each Nacos cluster, or enabling each Nacos cluster to be connected through a special line, and enabling any Nacos cluster to be connected with the Nacos database, wherein the special line is a special network channel among cloud servers.

In this embodiment, one Nacos cluster is deployed and configured on each cloud server, so that they can operate independently, and have their own nodes and configurations, and each Nacos cluster contains multiple nodes to improve high availability and load balancing. Client applications, which may be various services, applications or devices, are deployed on each cloud server and ensure that they can connect to the corresponding Nacos clusters, obtain configuration information, service discovery, etc. through the Nacos clusters.

In this embodiment, there are two network architecture modes: first, as shown in fig. 2, the architecture diagram includes a plurality of cloud servers (cloud server 1, cloud server 2.....cloud server n), each cloud server is provided with a Nacos cluster, each Nacos cluster comprises an entrance LB, a leader node, a follower node and a local cache layer, the client and the entrance LB are connected, corresponding service configuration information of Naocs clusters is obtained through the entrance LB, each Nacos cluster stores data to the same Nacos database, in this case, although all Nacos clusters read the same Naocs database, when any cloud server Nacos cluster has a write operation, the leader node will only read data from the Nacos database to the local cache at intervals due to the existence of the local cache layer, and there is a time difference in implementing synchronization of service configuration information of Nacos clusters on multiple cloud servers, so that the local cache time interval needs to be shortened as much as possible to achieve the effect of data synchronization; second, as shown in fig. 3, the architecture diagram includes a plurality of cloud servers (cloud server 1, cloud server 2.....cloud server n), each cloud server is provided with a Nacos cluster, each Nacos cluster includes an ingress LB, a leader node, a follower node, and a local cache layer, clients and ingress LB implement a connection, corresponding service configuration information of Naocs clusters is obtained through an inlet LB, each Nacos cluster is connected through a dedicated line, in this case, any Nacos cluster is only required to be connected with a Nacos database, and at this time, the function of the Nacos database is mainly data persistence, because a real synchronization effect can be achieved through a plurality of Nacos clusters connected through the dedicated line.

In the first network architecture mode, the local buffer time interval needs to be short to achieve the synchronization effect, so that the pressure of the database is increased, but the cost of opening up each Nacos cluster through a dedicated line is saved at the same time, and in the second network architecture mode, although a dedicated network channel needs to be established for Nacos clusters on each cloud server, the resources of the database can be saved, and the Nacos database is mainly used for persistently storing data and is not used as a data interaction point between a plurality of Nacos clusters.

In this embodiment, by deploying one Nacos cluster on each cloud server, high availability of multiple regions and multiple machine rooms can be achieved, stability and reliability of the system are improved, network delay is reduced, and data transmission rate is improved.

In some embodiments, the method further comprises:

In this embodiment, when the leader node fails, the distributed coordination service tool, such as etcd, zooKeeper, consul, monitors the change of the state of the leader node through the monitoring mechanism of the distributed coordination service tool, so that the process can be performed in time when the leader fails, thereby reducing the fault recovery time, and simultaneously avoiding selecting the leader node through the temporary node sequence number under the condition that the election timeout times of a plurality of foullowers are shortest and the same, and improving the stability of the system.

Taking a ZooKeeper as an example, each of the ZooKeeper nodes participating in the Leader election creates a temporary ordered node under a designated ZooKeeper path, generates a node list after all temporary ordered nodes are created, creates a persistence node under the designated ZooKeeper path for storing global configuration information by the successfully selected Leader node, acquires the global configuration information of the persistence node through a getData method of the ZooKeeper, monitors the change of the persistence node through a Watcher method of the ZooKeeper, updates the data of the persistence node when the Leader node needs to update the global configuration information, and when the data of the persistence node changes, watcher of Follower nodes receives a notification to trigger the operation of processing configuration change, so that the mechanism can ensure the consistency of the configuration information in the distributed system among the nodes. Meanwhile, when the leader node fails (namely, a fault and other conditions occur), the follower node can also be informed of the conditions in time, and a new leader node can be reelected.

In some embodiments, after the enabling each Nacos cluster to connect to the same Nacos database at the same time and setting the local cache time interval of each Nacos cluster to a preset time, the method further includes:

In this embodiment, in the network architecture manner as shown in fig. 2, when a certain cloud server loses response, a client connected to the cloud server needs to be timely transferred to another cloud server, but since the Nacos cluster generating a new connection relationship with the cloud server does not have corresponding service configuration information, the service configuration information stored in the original Nacos cluster needs to be acquired from the Nacos database. Meanwhile, when the load of the current cloud server is too high, in order to realize load balancing, part of the currently connected clients are also required to be transferred to other cloud servers with more residual resource spaces, so that the possibility of service interruption is reduced, the reliability of the system is improved, meanwhile, the utilization of resources can be optimized, and traffic is prevented from being sent to the crowded or unavailable servers.

In some embodiments, after each Nacos cluster is connected by a dedicated line and any one Nacos cluster is connected to the Nacos database, the method further includes:

In this embodiment, in the network architecture manner as shown in fig. 3, when a certain cloud server loses response, a client connected with the cloud server needs to be timely transferred to another cloud server, because all Nacos clusters are connected through a dedicated line, which is equivalent to that each Nacos cluster forms the same Nacos cluster, the corresponding service configuration information of the client is not required to be read from the Nacos database, and only the service configuration information is required to be directly read from the original Nacos cluster, and through cooperation with the Nacos clusters, no perception can be realized in the switching process, so that the client can continue to operate normally without being affected. Meanwhile, when the load of the current cloud server is too high, in order to realize load balancing, part of the currently connected clients are also required to be transferred to other cloud servers with more residual resource spaces, so that the possibility of service interruption is reduced, the reliability of the system is improved, meanwhile, the utilization of resources can be optimized, and traffic is prevented from being sent to the crowded or unavailable servers.

In some embodiments, the method further comprises:

and storing the authority configuration information into the name space.

In this embodiment, in Nacos clusters, namespaces are created through the management console or API, and each client is assigned a separate namespace, each namespace having a unique identification, to ensure that when the cloud server connected with the current client loses response or the residual resource space is lower than the preset space and needs to switch over a new cloud server, the new memory space for storing the service configuration information can be rapidly determined in the new Nacos cluster, meanwhile, the service configuration information between each client side is isolated in each Nacos cluster, the configuration information is prevented from being confused, and the safety is improved. And, by integrating OAuth 2.0 framework, according to OAuth 2.0 authorization mechanism, to ensure that each client has a unique identity, different rights are assigned to different clients, flexible and accurate authority control is realized, and in certain application scenes, the client can be assigned with authorities such as an administrator, a common user and the like, and different member user grades can be set.

In some embodiments, the method further comprises:

In this embodiment, CI/CD tools are deployed on each cloud server, such as Jenkins, gitLab CI/CD, etc., and configure connections to Nacos clusters and external code repositories, respectively, the CI/CD tools periodically or through Webhook monitor the external code repositories (e.g., gitHub, gitLab, etc.), trigger CI/CD processes when code updates are detected, the CI/CD tools pull the latest application code from the code repository, and perform compiling, testing, etc. operations according to the build script, integrate Docker with the CI/CD tools, generate container images of the applications according to Dockerfile, etc. configuration files, push the generated container images to container image repositories, such as Docker Hub, ali cloud container image services, etc., then pull the container images to the target cloud server, and start the container, and call Nacos configuration management APIs through the CI/CD tools to update service configuration information in the Nacos clusters. When updating the application program, the client monitors the configuration change in real time through Nacos clusters, acquires the latest service configuration information, and ensures the matching with the updated application program. By the embodiment, a full-automatic process from code updating to application deployment is realized, and development and deployment efficiency is improved.

In some embodiments, the method further comprises:

In this embodiment, tools such as Prometheus, grafana, datadog are used to monitor the performance index values of the client, including but not limited to CPU utilization, memory utilization, network traffic, response time, etc., tools such as Sentry, new Relic, ELK Stack (ELASTICSEARCH, LOGSTASH, KIBANA) are used to capture errors and anomalies in the running of the client's application, while real-time data stream processing frameworks (e.g., APACHE KAFKA, APACHE FLINK, etc.) may also be used to process the monitored data in real-time and store the monitored data in a suitable storage system. When the client is updated, the performance of the client is not the same as that of the previous version, or the number of error anomalies is higher than that of the previous version, the client can automatically roll back to the previous version to improve the stability and usability of the system, the client can quickly respond and roll back to the previous version when the problem is found through an automatic pipeline of a CI/CD tool, preventive maintenance can be carried out before the performance problem or the error anomalies have no obvious influence on users, and potential performance problems and anomalies can be timely processed.
