This section details how to configure a High Availability Load Balancer in Azure for Kyvos using Azure Application Gateway to distribute web traffic and ensure reliable access to Kyvos services.

Azure Application Gateway is a web traffic load balancer that enables you to manage traffic to your web applications. Traditional load balancers operate at the transport layer (OSI layer 4 - TCP and UDP) and route traffic based on a source IP address and port to a destination IP address and port.

Application Gateway can make routing decisions based on an HTTP request's additional attributes, for example, URL path or host headers. You can route traffic based on the incoming URL.

This document explains the steps to be followed to configure the Application Gateway in Kyvos version 2020.4

High Availability Configuration

Azure allows you to configure the load balancer using the following options. You can choose the type of configuration depending on your business requirements.

• HTTP Connectivity

  • Public load balancer: In this case, create a load balancer with a public IP.

  • Private load balancer: In this case, Azure recommends creating one private (internal) and one public load balancer (with outbound rules defined) to create outbound connectivity for VMs behind an internal load balancer.

• HTTPS Connectivity

•  

  1. Application Gateway with Public IP: In this case, you need to create a load balancer with a public IP.

  2. Application Gateway with Private IP: Kyvos is not yet certified for this.
