3-Way Replication

3-Way Replication is a system where data is duplicated across three different locations or servers. This setup ensures that if one server fails or experiences issues, the data remains available from the other two. It enhances data durability, availability, and disaster recovery by providing multiple copies in separate places. Essentially, it's like having three backups spread out so that your data stays safe even if one or two copies are compromised. This method is used by organizations that require high reliability and minimal downtime for their critical information.
