Well in fact we are using a solution ELB => (Apache + WO) instances
Every instance is running its own Apache and WO, so the AWS ELB can address
the Apache as a classical webserver, then mod_WebObjects does its magic.
The Apache's footprint on the instance is extremely small compared to the
JVM WO machinery...

Hi Steve,
Actually we're using m4.xlarge instances with AWS loadbalancer and it works
quite well, with something like 12 WO instances on each ec2 instance.
Cool !!
Quick question, are you using AWS loadbalancer to talk directly to the
instances (similar to how mod_proxy on apache works),
or is the ELB accessing (1 or more) Apache instances?
so it it:
1) ELB ==>> WO Instances?
or
2) ELB ==>> Apache(s) ==>> WO Instances
Please say (1), please say (1), please say (1), please say (1).

Can handle around 1500 requests/sec (we have heavy load on RDS Postgresql
DB, would need optimization ;-) ).
Hope this helps.

Hi List,
I am moving to AWS and wonder if any of you have suggestions concerning
what EC2 instance types to use. I have many clients which multiple
instances and my WOApps use significant memory. I am currently running
aging servers which are packed full of memory so memory use has not been
limitation. AWS seems great, but it starts looking expensive when I set up
instances with the amounts of memory I am used to.
Any suggestions?
Thank you,
Steve
