Solaris free/open source clustering/load balance
|
|
| Subhodini Fernandes 2004-04-04, 4:36 am |
| I am looking for some free/open source clustering software which I can
use on Solaris to load balance/fail over web server Tomcat. I have
done a google search but problem is that there are so many its often
confusing.
The requests will come to one single ip address which in turn will go
to any Tomcat web server that is free and the request will be routed
to a back end application (which is on another server).
Any suggestions will be highly appreciated.
Thanks,
Subho.

This is exactly how heartbeat operate. When a node goes down or is
unreachable
all the resources are switching to the other node. When the master server
come back up
the resources switch back to the master server.
You can use a single IP per services so it's easy to watch the IP takeover.
I have some services that switch in less then 5 seconds.

They why call it Linux-HA? I guess lot of people were put off by its name
and classified it under YALP (yet another Linux-only product).

But the original request was for load balancing and you are talking about
fail-over. These are two different issues.

Probably because it was originally develop on linux.

AFAIK the original poster was looking for load balance/fail over :
" I am looking for some free/open source clustering software which I can
use on Solaris to load balance/fail over web server Tomcat."

Fair enough.

Possible. But the above "The requests will come to one single ip address
which in turn will go to any Tomcat web server that is free" sounds like
load balancing to me.
Is there any other general purpose "load balancing" cluster software except
for Sun Cluster? That runs on Solaris, of course?
