If there is only disaster recovery, the production side has wrong operations, or the system upgrade fails, etc., it will be Synchronizing to the disaster recovery side will also cause data or business interruption.

The backup is generally performed periodically. Once the data is damaged, the data will be restored from the recovery time to the last backup time. data in between will be lost.

If there is only backup, the business cannot be recovered quickly, and data recovery takes time. During this time, the business cannot be used. For a certain industry, such business interruption cannot be tolerated.

If there is only disaster recovery, business can be quickly recovered and data can be protected.

Upload the image file to the OBS bucket before registering the image, and the system will upload the image directly when registering the image.

Upload to Glance

When registering the image type of FusionCompute, use OBS as the image server and require OBS to serve

The IP address of the service communicates with the management plane of the CNA

If you want to delete the image and use the image file in the OBS bucket at the same time, you can configure OBS as Glance

Configuring the cluster HA strategy is to automatically adjust the resource load balancing on different hosts

Dedicated failover hosts refer to: setting a specified number of hosts in the cluster to fail, the system

Periodically check that there are enough resources left in the cluster to fail over the virtual machines on these hosts

To allow host failure in the cluster refers to: Reserving a designated host as a dedicated failover host, when the host is used as a failover host, ordinary virtual machines are prohibited from starting, migrating, waking up, and snapshot recovery on the host

HA resource reservation is to reserve CPU and memory resources according to the configured values ​​in the entire cluster

RTO is infinitely close to 0. Even if synchronous replication is used, the business still needs some time,

The smaller the RTO value, the less data is lost

The smaller the RPO value, the smaller the service interruption time.

In theory, RPO can be equal to 0. When disaster recovery or backup uses synchronous replication, the same

Step data, RPO can be achieved equal to 0.
