Synchronous Replication is a data management technique where data is copied in real-time from one location to another. This means that when a change is made to the primary data source, it is immediately replicated to a secondary location. This ensures that both copies of the data are always up-to-date and consistent, which is crucial for applications that require high availability and reliability. In synchronous replication, the process typically involves a network connection between the primary and secondary sites. If the primary site fails, the secondary site can take over without any data loss. However, this method can introduce latency, as the system waits for confirmation that the data has been successfully replicated before proceeding.
