Geo-Failover for Critical Applications

For mission critical applications, implementing a geo-failover solution gives you peace of mind.

Benefits of Geo-Failover and Replication

Business Continuity
Your business can continue to operate without interruption in a natural disaster or unforeseen event.
High Availability
With Geo-Failover, keep your mission critical applications online even if something happens at the primary data center that causes an interruption.
Secure Data
Keep your data synchronized across data centers in real time with end to end encryption to keep your data safe even during transit.
Real-time DR
A Geo-failover plan takes Disaster Recovery to the ultimate level by providing real-time failover so you don't have an interruption to your business.

So what is geo-failover?

A properly configured Geo-failover cluster setup provides both a primary and a secondary application infrastructure so that in the event of an interruption (down time) at the primary location, the application automatically fails over to the secondary server cluster location providing for continuous operation of your mission critical applications.

Primary

A primary server (or load balanced server cluster) combined with a primary database server located at the primary location (generally a data center).

Secondary

A secondary server (or load balanced server cluster) combined with a secondary database server located at the secondary location (best practice is in a data center in a different state than the primary location) where the data is replicated to.

Replication

Replication involves copying and maintaining database objects or files in multiple locations for the purpose of redundancy and increased data availability.

Replication Options

Synchronous Replication

Data is written to multiple locations at the same time. This ensures that all copies are always up-to-date, but it can introduce latency due to the time it takes to confirm writes across locations.

Asynchronous Replication

Data is written to one location and then copied to other locations. This can reduce write latency but may lead to temporary inconsistencies between copies.

Geo-Replication

This is a form of asynchronous replication where the data is replicated across geographically dispersed sites. It is often used to provide data locality and to ensure data durability in case of regional failures.
