Why each option
Configuring synchronous datacenter replication over an MPLS WAN creates a real-time data mirror between sites, which provides datacenter redundancy for the company.
MPLS circuits are premium, dedicated WAN services that are more expensive than standard internet links, so deploying them increases rather than reduces infrastructure costs.
MPLS provides predictable, quality-of-service-guaranteed bandwidth but does not increase the total amount of network bandwidth available to the organization.
Off-site backups are point-in-time copies stored at a remote location for recovery purposes, whereas synchronous replication is a live continuous mirror and is not classified as a backup solution.
Synchronous replication continuously copies data to a secondary datacenter in real time over the MPLS WAN, meaning if the primary site fails the secondary site has an identical, up-to-date copy ready for immediate failover. This architecture provides datacenter redundancy, ensuring high availability and zero data loss for cloud-connected workloads even during a full site outage.
