OCI load balancer redirection using Routing Policies

In Layman terms, load balancers helps in distributing the requests to the backend servers based upon certain algorithms. OCI Load Balancers helps in achieving high availability and scalability. Based upon our requirement we can induce multiple policies and application level health checks in OCI Load Balancer. In this post, i am going to demonstrate how we can leverage routing policies to redirect requests to backend servers using certain conditions. If you want to know how to create a Load balancer, you can refer to my earlier post https://samappsdba.blogspot.com/2020/05/configuring-oci-load-balancer-for-ebs.html

 I have a webserver1 with Public IP:-X.X.X.65. This is registered under DNS as dumka.tk 

I have an another webserver2 with Public IP:-X.X.X.61. This is registered under DNS as dumka.ml

Now i will create the Load balancer

I will add the backend later

Load balancer will now be created.

Add the backends now

Create listener for two backends

Now create the hostnames

Edit the listener and add the respective hostnames

Now Define the Routing Policies

At last, add the Public IP of the Load balancer to the DNS Zones.

Perform the testing

There are many other advanced configurations which we can use with our OCI Load Balancer for which we can go through the Advanced OCI LB Concepts. You can also refer my earlier post OCI LB Redirection on how i had used Path Route set for Load balance Redirection. This post is all about how using one Network load balancer, we can serve multiple websites using hostname and Routing policies. Hope this post helps someone. Keep learning cloud.
