Disaster recovery is more important than HTTPS SNI support…

Posted by James Bolton 1st July in Disaster recovery

What would you prefer us to work on? Making sure that you get zero downtime, or reducing the amount of manual configuration required? Here at Loadbalancer.org we've been working hard (i.e. drinking lots of coffee) and we are very relieved to announce, that v8.2.1, is now available - finally.

Posted by Rob Cooper 1st July in Disaster recovery

So, you've configured two loadbalancer.org appliances as a clustered pair for high availability, the pair has been working fine but then one day you receive an email alert that one of the pair has failed for some reason, for example a disk failure. The remaining unit continues to provide load balanced services without issue, but now you want to repair the failed unit and re-create the clustered pair without any disruption to running services.

Posted by Dave Saunders 29th May in Disaster recovery

Every system administrator, infrastructure manager and experienced user knows the importance of having current backups available... just in case!

Some small changes to default settings make achieving high availability easier…..

Posted by Malcolm Turnbull 17th May in Disaster recovery

Loadbalancer.org has always been about high-availability, that is the fundamental reason for our products existence. Performance has always been a nice side effect while maintainability of your application cluster is generally a key sub-set of the primary high-availability objective. However it's time for a confession, the default settings for the Loadbalancer.org appliances in a cluster configuration up until v7.5 have been set by default  for both ease of use and certainty of a valid configuration. The default recommendation for setting up or disaster recovery on the high-availability of the cluster (Heartbeat) has been to force a full sync and therefore inflict a small amount of down time in a maintenance window. Whilst we've always had documentation showing how to handle cluster maintenance and configuration with zero downtime it was definitely time for a change.
