Multi-Region
Replication

Multi-region replication is a deployment topology that enables system continuity, by replicating states between various geographical locations. It is commonly used for:

plane-icon

Disaster recovery planning: locating each deployment site far apart (even on different continents) to enable normal operations should one site fail

plane-icon

Failover: when one site acts as a failover over target for another site

plane-icon

Maintaining data locality: per site, to enhance performance and lower latency

plane-icon

Add or remove remote sites: without system shutdown

The GigaSpaces WAN Gateway offers:

Optimized bandwidth and WAN connection usage: single connection to interact with remote sites, enables efficiency and lower costs

Indirect replication:
allows replication of a packet from point A to point B via point C, to avoid connectivity problems between points A and B

Total data consistency: since the WAN Gateway is totally stateless, transactions at the local site are replicated in the correct order to the remote sites, minimizing data loss

Multi-Master / Master-Slave support: supports all popular replication topologies

Conflict resolution support: GigaSpaces identifies data conflicts so that local copies can be replicated with the remote copy, or the remote copy can replicate the local copy, or both the local and remote copies can be merged

Site bootstrapping: after site startup, it can reload its entire data set, or specific data from a remote site without introducing data consistency problems

Monitoring and Management: comprehensive statistics on all replication activities

Data filtering: uses a custom plug-in that allows filtration/modification of data at each source/target node, before and after it has been replicated

Encryption on the wire: addresses security challenges
