Hello,
I'm familiar with load balancing to some degree but have some questions regarding some specifics of our current sitation.
First, we have our systems -
2 Portal production servers - EPP1 (Central DB instance) and EPP2 (dialog instance)
3 R/3 Application servers - call them: AP1, AP2, and AP3.
Currenlty we have web applications that pull data from these R/3 systems, and we are looking to, very soon, have a handful of those applications converted over to Portal applications. Put simply, it will be the same job (getting the same data) but instead of going to a webpage to get it, people will be going through our portal via SSO (logon tickets). Eventually we want all our online applications to go through the portal, etc.
We are planning to implement a hardware loadbalancer from the Web to the 2 portal production servers. However, my question is how is the load balancing is handled between the 2 portal servers and the 3 backend R/3 application servers?
Currently, load balancing on the R/3 application servers are handled via logon groups and we are satisfied with that. Would I need to change any load balancing between the Portal and backend application servers? Seems like if it's already working well, and users are logging in with their same userids (and in the same groups) then it should be handled the same way. Maybe this is just a naive way of looking at it however.
Any ideas, comments? I'll award points for anything helpful.
Thanks!!
