Let us learn more about the Hetzner load balancer with the support of our Server management support services at Bobcares.

What is Hetzner load balancer?

This is a Hetzner service that helps disperse incoming network traffic over numerous servers in order to improve the overall speed and availability of web applications or websites.

Load balancing can help us handle large traffic volumes while also improving response times and increasing fault tolerance.

Hetzner Firewall, on the other hand, is a firewall solution particularly designed for load balancer service.

The firewall guards the load balancer and underlying servers from unauthorized access and harmful traffic.

To enforce security regulations and prevent unauthorized access, it often incorporates capabilities such as IP filtering, port-based filtering, and application-layer filtering.

How do the algorithms work?

Round Robin:

This algorithm prioritizes traffic distribution. To put it simply, inbound request 1 is routed to server 1, request 2 to server 2, and so on. Finally, the algorithm returns to server 1 and repeats the process.

Least Connections:

This algorithm analyzes server traffic. Incoming requests are routed to the server with the least amount of traffic available at the time.

How to create a load balancer on a Hetzner server?

We may use the following general procedures to set up a load balancer on the server:

1. Set up the servers:

   Firstly, set up extra servers to act as members of the load balancing group. These servers should be setup to handle incoming traffic and host the application or website.
2. Choose a load balancer solution:

   We can use “Hetzner Cloud Load Balancer” load balancer service. Depending on the individual needs, we may also employ different load balancing technologies such as Nginx or HAProxy.
3. Configure the load balancer:

   If we select Hetzner Cloud Load Balancer, we must first log in to our Hetzner Cloud account, then travel to the “Load Balancers” area and click on “Create Load Balancer.”

   To setup the load balancer, follow the instructions given. This usually include defining the forwarding rules, health checks, and backend servers.
4. Set up DNS:

   Change the DNS records to refer to the load balancer’s IP address. This directs incoming traffic to the load balancer, which distributes it to the backend servers.
5. Test and monitor:

   Finally, after we’ve setup the load balancer and DNS, test the application by visiting it via the load balancer’s IP address or domain name.

   Check that the load balancer and backend servers are working properly and distributing traffic as planned.
