> You can use geo-replication to create secondary replicas in the same region as the primary. You can use these secondaries to satisfy read scale-out scenarios in the same region. However, a secondary replica in the same region does not provide additional resilience to catastrophic failures or large scale outages, and therefore is not a suitable failover target for disaster recovery purposes. It also does not guarantee availability zone isolation. Use Business Critical or Premium service tiers [zone redundant configuration](high-availability-sla-local-zone-redundancy.md#zone-redundant-availability) or General Purpose service tier [zone redundant configuration](high-availability-sla-local-zone-redundancy.md#zone-redundant-availability) to achieve availability zone isolation.

- **Failover (no data loss)**: When a Failover (no data loss) is initiated, a full data synchronization step is completed before switching the roles of the primary and geo-secondary databases. This ensures there is no data loss Duration of the failover depends on the size of the transaction log on the primary that needs to be synchronized to the geo-secondary.
