You can achieve load balancing by deploying a dedicated load balancer software as a cloud server. Here’s a tutorial on how to set this up:

1. Choose Your Load Balancer Software

Popular options include:

• HAProxy: Open-source and lightweight, known for its efficiency.
• NGINX: Open-source web server that can also function as a load balancer.
• Load Balancer.org: Free and commercially supported option with a web interface for easier configuration.

2. Create a New Cloud Servers with the Load Balancer Operating System

3. Install and Configure the Load Balancer Software

• Once the VM is created, start it. The boot process will guide you through installing the chosen load balancing software on the VM.
• After installation, access the web interface or command line of the load balancer VM (depending on the software) to configure it.
• This configuration typically involves defining:
  • Listeners: Ports on which the load balancer will listen for incoming traffic (e.g., port 80 for HTTP).
  • Backend Servers: Specify the IP addresses and ports of your virtual servers that will handle the requests.
  • Health Checks: Configure health checks to monitor the health of your backend servers.
  • Load Balancing Algorithm: Choose an algorithm (e.g., round robin, least connections) for distributing traffic across servers.

4. Additional Considerations

• Security Groups: Configure firewall rules on your cloud server or within the load balancer software to control access to the load balancer and backend servers.
• High Availability (Optional): Consider setting up redundant load balancer VMs for increased fault tolerance.

5. Resources

For detailed configuration steps, refer to the documentation of your chosen load balancer software:

• HAProxy: https://www.haproxy.com/documentation/haproxy-configuration-manual/latest/
• NGINX: https://docs.nginx.com/nginx/admin-guide/load-balancer/http-load-balancer/
• Load Balancer.org: https://pdfs.loadbalancer.org/loadbalanceradministrationv8.pdf

Important Note: Installing and configuring software within a VM on Proxmox requires familiarity with Linux administration and the specific load balancing software. Consider your technical expertise when choosing this approach.
