Application Scenarios

The user already has large scale applications. His/Her focus has been shifted from the balance between infrastructure deployment and business growth to the stability and reliability of the infrastructure for multi-center development. He/She hopes to eliminate business risks caused by single IDC failure through eliminating single IDCs.

User's core pain point

  • How to realize multi-location disaster recovery and improve infrastructure reliability.
  • How to realize fast deployment while reducing infrastructure construction period.
  • How to re-use stock IDC to reduce operating costs (use existing servers first).

Solutions:

Hybrid cloud disaster recovery deployment

  • Multi-location IDC deployment: Build master/slave clusters in local IDC and public cloud IDC.
  • Data synchronization: Synchronize data via Direct Connect or VPN to avoid single IDC failure.
  • Traffic forwarding: Provide lossy but uninterrupted services by forwarding the traffic to normal IDCs.

2-region-3-DC disaster recovery deployment in cloud

  • Cross-availability zone deployment: You can create subnets and deploy services in different availability zones within one VPC. Data can be synchronized between subnets of different availability zones. The goal of using different availability zones is to ensure that the failures are isolated from each other.
  • Cross-region deployment: You can deploy the same service in the VPC of another region to achieve multi-location disaster recovery and avoid failures in one region from spreading to other regions.
  • Cross-region high-speed interconnection: VPCs of two different regions achieve interconnection via cross-region peering connection.
    Traffic forwarding: it provides lossy but uninterrupted services by forwarding the traffic to other normal IDCs when an IDC breaks down.

Procedure

Steps of hybrid cloud disaster recovery deployment

  1. Create a VPC on Tencent Cloud and deploy IDCs. For more information, please see VPC Instructions.
  2. Synchronize the local IDC and the VPC IDC on the cloud via Direct Connect. For more information, please see Direct Connect Instructions.
  3. Forward the traffic to other normal IDCs when an IDC breaks down.

Steps of cloud 2-region-3-DC disaster recovery deployment

  1. Cross-availability zone deployment. You can create subnets and deploy master and slave synchronization service in different availability zones within one VPC. Data can be synchronized between subnets of different availability zones. The goal of using different availability zones is to ensure that the failures are isolated from each other. For more information, please see Subnet Instructions.
  2. Cross-region deployment. You can deploy the same service in the VPC of another region to achieve multi-location disaster recovery and avoid failures in one region from spreading to other regions. For more information, please see VPC Instructions.
  3. Cross-region high-speed interconnection. Create a cross-region peering connection to achieve high-speed data synchronization between two VPCs. For more information, please see Peering Connection Instructions.
