What types of server mirroring zones are available?

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:

  1. 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.

  2. 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.

  3. 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.

  4. 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.
