lovely systems is running business critical software and it’s important for us and our customers that the entire system is fully redundant and high available.

in consequent of this we have a 3 steps plan:

• load balancing with automatic failover
• hot standby where load balancing isn’t possible
• quick and easy recovery if data loss occurs

load balancing is alread implemented. i’ve written a german howto about it.

hot standby is finishing the last stability tests. again i’ve written two howto’s about drbd and heartbeat.

the backup setup is going productive in the near future. i’m going to write a howto about that in the next few days.

after this steps there shouldn’t be a bottleneck any more.
