In the first post of this series, I discussed how Avi Controller & Service Engines are deployed in an SDDC running in VMC on AWS. 

In this post, I will walk through the steps of configuring a load balancer for web servers.

Lab Setup

The diagram is a pictorial representation of my lab setup.

Let’s jump into the lab and start configuring the load balancer. 

I have deployed a couple of web servers running on CentOS 7.

These are plain HTTP servers with a sample web page. 

Load Balancer Configuration

Create Session Persistence Profile

A persistence profile controls the settings that dictate how long a client will stay connected to one of the servers from a pool of load-balanced servers. Enabling a persistence profile ensures the client will reconnect to the same server every time, or at least for a desired duration of time. 

Cookie-based persistence is the most commonly used mechanism when dealing with web applications.… Read the rest

Load balancers are an integral part of any data center, and most of the enterprise applications are clustered for high availability and load distribution. The choice of the load balancer becomes very critical when applications are distributed across data centers/clouds. 

This blog series is focused on demonstrating how we can leverage Avi Load Balancer for local/global load-balancing applications in VMC on AWS. 

If you are new to Avi Load Balancer, then I encourage you to learn about this product first. Here is the link to the official documentation for the Avi Load Balancer

Also, I have written a few articles around this topic, and you can read them from the links below:

2: Avi Controller Deployment & Configuration

3: Load Balancing Sample Application

The first two parts of this blog series are focused on the deployment & configuration of Avi LB in a single SDDC for local load balancing.… Read the rest
