Server mirroring zones typically refer to different configurations or locations where server mirroring (replication) can be implemented to ensure high availability, disaster recovery, or performance optimization. The main types include:
Local Mirroring Zone: Mirroring within the same data center or physical location. This provides fast failover but doesn’t protect against site-wide failures.
Example: A database server mirrored to another server in the same rack for low-latency replication.
Regional Mirroring Zone: Mirroring across multiple data centers within the same geographic region. This balances performance and redundancy.
Example: A web application’s backend servers mirrored across two data centers in the same city.
Cross-Regional Mirroring Zone: Mirroring between geographically distant regions. This ensures disaster recovery and compliance with data residency requirements.
Example: Using Tencent Cloud’s Cross-Region Replication feature to mirror a storage bucket from Beijing to Shanghai.
Hybrid Mirroring Zone: Combining on-premises servers with cloud-based mirroring for flexibility and scalability.
Example: A company’s on-premises database mirrored to Tencent Cloud’s Cloud Database MySQL for backup and failover.
For cloud-based solutions, Tencent Cloud offers services like Cloud Block Storage (CBS) Replication and Tencent Cloud Database (TencentDB) Cross-Region Replication to support these mirroring zones.
