What is the main purpose of the Metro Availability technology?

Metro Availability technology is primarily designed to enable synchronous replication between clusters. This means that it allows data to be replicated in real-time across different geographic locations, ensuring that multiple clusters maintain identical copies of data simultaneously. This capability is crucial for high availability and disaster recovery scenarios, as it helps organizations maintain operational continuity even in the event of a site failure.

With synchronous replication, any changes made to the data in one cluster are immediately mirrored in the other cluster, resulting in minimal downtime and data loss. This is particularly important for applications that require high levels of data consistency and availability.

While other options may touch on aspects related to data management or efficiency, they do not encapsulate the primary function of Metro Availability, which is specifically focused on maintaining synchronized data across multiple locations to provide robust fault tolerance and high availability.
