Is it a good idea to have single loadbalancer to have multiple groups ?

[arun2arunraj]

Hi,

We are having 5 Server-Groups each groups contains 2 nodes each in two different hosts. More over, we are using Apache as our front end.

Right now, I have configured a single loadbalancer in the apache level. My Configuration is following.

Listen 127.0.0.1:7777

Maxhost 1000

Maxnode 1000

<IfModule manager_module>

  <VirtualHost 127.0.0.1:7777>

    ManagerBalancerName myservicelb

    ServerName 127.0.0.1

      <Location />

            Order deny,allow

            Allow from all

      </Location>

      KeepAliveTimeout 300

      MaxKeepAliveRequests 0

      EnableMCPMReceive

      AllowDisplay On

      <Location /mod_cluster_manager>

            SetHandler mod_cluster-manager

            Order deny,allow

            Deny from all

            Allow from *.domain.com

     </Location>

     <Location /server_status>

            SetHandler server-status

            Order deny,allow

            Deny from all

            Allow from *.domain.com

     </Location>

  </VirtualHost>

</IfModule>

I have just changed my ip address into loopback address.

Applications are working. But Having no idea whether I have done a good configuration. Is it a good idea to have a single LoadBalancer for a multiple groups. I have deployed 2 or 4 applications in each groups.

Dear Arun,

what do you mean by "a group"? If you are suggesting that you have more load balancing groups, it's perfectly fine to have a setup with one load balancer.

Dear Michal,

Thank you so much for the quick reply. Really sorry for posting a question in confusing manner. According to me , a group is this link.

We are doing the following things. That is why I have raised the discussion.

( i ) We are having two or more context deployed in a single JBoss EAP Group.
( ii ) In Each JBoss EAP Group, We are having different Context or applications.

( iii ) We are using Prefork as a MPM.

I dont know whether having a single load balancer ( ManagerBalancerName cluster ) is good or not. Please guide me

If you are suggesting that you have more load balancing groups, it's perfectly fine to have a setup with one load balancer. Can you please explain me , I am very new to load balancing with Apache
