(Sorry I don't know what its technology is termed exactly. High Availability OR load balancing)
What I'm going to explore is as follows:-
For example, on Physical Servers;
Server-1 - LAMP, a working server
Server-2 - LAMP, for redundancy
While Server-1 is working all working data will be synchronized/duplicated on Server-2 simultaneously. When Server-1 is down for whatever cause the network will be switched automatically to Server-2. No interruption will be caused. Server-2 will continue to work. Then Server-1 can be repaired/upgraded/reconfigured etc.
Now I want to do it on VMs of Oracle VirtualBox.
Can any folk point me some links. Google brought me some links but I'm not sure which of them will be my guide. TIA
Check this out: google.com -> "switch fault tolerance"
Intel got adapters and drivers which you can use and have necessary features.
I cannot post full link, because of number of my posts is smaller than 5.
i run a sun cluster (oracle now) in virtualbox on my notebook. all you need is vbox, solaris and the cluster software. and all can be downloaded at oracle.
