Load balancing between any number of Joomla sites with fail-over if one of the identical sites goes down can be achieved without database replication. This solution is infinitely scalable, just by replicating a site, creating a grouping of sites and adding at existing and newly replicated sites to the group The sites are then configuring behind a load balancer.

Content updates to the sites, either by the Jentla content management workflow or via user generated content are sent to the Jentla Manager then distributed to the sites, making it possible to keep a group of sites identical.

For even a higher level of redundancy, the Jentla Manager can also be replicated at the application layer to form date replication group.

This entirely removes the need for complex database replication and all the associated costs and instability.

Although the sites are grouped, they can be hosted in multiple data centres, making low cost multi-location a reality. Because the data traffic between the locations is limited to content updates, which is very low in volume compared to a database sharing/replication solution, the cost of data traffic is very significantly reduced.

A Jentla High Availability solution can be set up in less than an hour compared to days for a database replication system.
