Application Scenarios

  • Cross-AZ DR

  • Non-disruptive DR Drills

Cross-AZ DR

Cross-AZ DR

The synchronous replication technology used at the storage layer provides DR protection between AZs to ensure data consistency. If the source AZ becomes faulty, services can be quickly restored in the target AZ.

Advantages

Substantial Capital Savings
Zero in-house infrastructure build requirement also removes the associated operational costs like power, air conditioning, and the need for self-administered O&M. You simply pay for what you use and can adjust at any time.
Robust Security
With the advanced synchronous replication tech yielding an RPO of 0, data is always secure and never lost.

Related Services

Non-disruptive DR Drills

Non-disruptive DR Drills

Drills are performed in the sandbox, leaving services in the source AZ remain completely unaffected.

Advantages

Zero Service Interruption
Applications running on the servers do not need to be stopped, and the servers do not need to be shut down during the drills.
Ease of Use
Just a few simple clicks allow your personnel to run DR drills over the console with fail-safe assurance so you can validate your DR strategy without data loss or downtime.
