I have multiple virtual hosts configured in apache using vhosts file listing all virtual hosts. Say if I now use load balancer dashboard.xyz.com, callback.xyz.com both pointing to different document root

do I have to use different load balancer instances to achieve this? I am trying to configure it using the same loadbalencer…

say if i point dashboard.xyz.com and callback.xyz.com both pointing to a single loadbalancer can apache find out which request corresponds to which document root dynamically? How do you achieve that…

with out using load balancer we can easily achieve that using apache dynamic virtual hosts listing different document roots in the mapped file…but with load balancer this logic is failing as if we hardcode load balancer document root it goes to a single document root instead of two or more domains….since loadbalancer terminates all incoming domain requests to single domain name and tries to go to the single document root….

kindly please let me know if community has any solution…

Hi,

I have launched a ELB but not able to login to the application. Application on both these instances are fine when accessed with IP address\path\

I removed one instance from load balancer and tried. Now application is accessible by using ELB (http://appli-153124424.us-east-1.elb.amazonaws.com/).
after adding another instance it goes to login page but cannot login.

Is there anything am i missing here.

Please someone suggest .

ELB has SSL Termination support now.

For MySQL load balancing, you only need to open 10.0.0.0/8 on 3306. The ELB connects to EC2 instances using an internal IP.

Is it possible for ELB to configured to talk to a server outside AWS? something like direct server return?

For example, I have a server located in some colo facility and I would like to use the ELB and make this server part of the farms?

But on which server do you do the mod rewrite redirection? If you’re putting it on the load balanced servers, they won’t be reached in the first place. So you need to use one of them through an elastic ip address just for this redirection basically, right?

The Elastic Load Balancing detects unhealthy instances within a pool and automatically reroutes traffic to healthy instances until the unhealthy instances have been restored.
