Hong Kong Cloud Server's fault tolerant system can ensure high service availability and business continuity, the fault tolerant system is designed to automatically switch to the backup system in the event of a system or hardware failure to minimize service interruption and data loss. What are the fault tolerant systems for Cloud servers in Hong Kong?

Hardware redundancy means that a data center is equipped with multiple hardware devices with the same function, so that the primary device can be quickly switched to the standby device when the primary device fails. For example, multiple data centers are used to share load and back up data. When one data center fails, another data center can take over services. Install multiple power supply systems in the data center to ensure that the backup power supply can seamlessly take over if the main power supply fails. Use multiple cooling systems to avoid a single point of failure resulting in excessive temperature in the data center, which affects equipment operation.

Load balancing is also one of the fault tolerant systems of Hong Kong Cloud Server. Load balancing can distribute the needs of users to multiple servers to ensure that no single server will bear too much load, thereby improving the reliability and performance of the system. For example, a dedicated hardware load balancer is used to distribute network traffic to multiple servers. A software load balancer distributes traffic to different servers according to configuration rules. DNS records allocate user requests to different IP addresses to achieve load balancing.

Data backup and recovery, to ensure that data loss or damage, can be quickly restored to ensure business continuity. Regular backup, such as full backup and incremental backup, is used in the Hong Kong data center to ensure data integrity and recoverability; Snapshot technology is used to create a point-in-time copy of data for quick recovery when data is damaged. Remote backup: Backup data is stored in data centers in different geographical locations to prevent data loss caused by natural disasters or other disasters.

The automatic failover system can automatically switch traffic to the standby system when the primary system fails, providing continuous service. For cluster configuration, if the cluster is configured on multiple servers, the standby node takes over when the primary node fails. The virtualization technology provides real-time migration to ensure that the virtual host can be migrated to another physical host if the physical machine is faulty. Load balancing and health check: The load balancer periodically checks the health status of servers. If a server is faulty, the load balancer switches traffic to the normal server.

The design of high availability architecture can greatly reduce the system failure time and ensure the continuity of system services. For example, using database cluster and replication technology, master-slave replication and database sharding can ensure the high availability of databases. Distributed system, the load and data are distributed to multiple nodes, improve the overall reliability of the system; Splitting the application into multiple microservices, each of which operates independently, reduces the risk of system failure caused by a single service failure.

Improve network reliability and availability through multiple network links and paths. Multiple physical network links are used to connect the data center to prevent network interruption caused by a single link. BGP is used to implement dynamic network routing and improve the fault tolerance of the network. Redundancy of network devices, such as switches and routers, ensures that backup devices can automatically take over when faults occur.

Service monitoring and alarm, real-time monitoring of the health status of the system, and find out problems in time to notify the administrator; Use monitoring tools to monitor system performance and resource usage in real time, configure an automatic alarm system, and notify administrators of abnormal situations by email, SMS, and other means. Analyze system logs to detect potential problems and take preventive actions.
