Basics
To understand the functionality of Hetzner Load Balancer, it is essential to grasp some key concepts. At its core, load balancing involves distributing incoming network traffic across multiple servers to ensure efficient resource utilization and avoid server overloads. Hetzner Load Balancer acts as an intermediary between clients (users accessing the website) and back-end servers.
One of the key advantages of Hetzner Load Balancer is its ability to handle high volumes of traffic. By distributing incoming requests across multiple servers, it helps prevent any single server from becoming overwhelmed and ensures that the workload is evenly distributed. Additionally, Hetzner Load Balancer automatically detects any failed or unresponsive servers in the cluster and redirects traffic to the healthy ones, thus ensuring high availability.
Another important feature of Hetzner Load Balancer is session persistence. It allows the load balancer to remember session information for a particular client and direct their subsequent requests to the same server. This ensures that users’ session data, such as login information or shopping cart contents, remains intact throughout their browsing experience.
