I have a request to load balance multiple instances of an application on one server. This application would be run on two servers but the requirement is to load balance 3 instances of the same application (on different ports) on the same server.


How should I go about this? Is it all possible to implement this?

this is possible.

On the CSS, you can create different services using the same ip but different port


ie:


service A1

ip address x.x.x.x

port 80

service A2

ip address x.x.x.x

port 81

service A3

ip address x.x.x.x

port 82


On the CSM, you do the same inside the serverfarm.


ie:


serverfarm MYSERVERS

real x.x.x.x 80

real x.x.x.x 81

real x.x.x.x 82

does the keepalive port need to be the same as the service port for this example of 1 IP and multiple instances with different port numbers. the keepalive type is http.

thanks

the keepalive port will be the same as the port configured for the service/rserver unless specifically configured to something else.

You could reuse the same port for the keepalive but different port for the application.

But normally you would want to poll the ports that you are using.
