Hello!
I want to try configure Linux cluster using few servers (only testing purposes). Can you advice me same clustering software (quite easy 
) and say why it is good in your opinion?
Thanks!
It depends on what clustering You’ve got in mind. For java telecommunication applications this is a nice choice :
Rhino Real-time Telecommunications Solutions | Telecom Application Server | JAIN SLEE 1.1 Compliant | Open Cloud Service Broker
It’s good because it supports IP and SS7 and more so is used by some telecom operators whose applications are almost always mission critical and even seconds of downtime can generate huge financial loss.
Best regards,
Greg
I rather think about testing some apache strong server which can support many clients and testing some virtualization environment - install few virtual systems in grid.
In most solutions I see that there is on master server. It looks for me like one failure point, so there must be used always some linux-ha?
