 [Load Balancers](/load-balancer/how-to/create-load-balancer/) are highly available and fully managed instances that allow you to distribute workload across multiple servers. They ensure the scaling of all your applications while securing their continuous availability, even in the event of heavy traffic. They are commonly used to improve the performance and reliability of websites, applications, databases and other services.
 
+## Maximum connections
+
+`Maximum connections` is a parameter that defines the maximum number of simultaneous requests (for HTTP) or simultaneous connections (for TCP) permitted for a single Load Balancer. The value depends on the Load Balancer type:
+
+- **LB-S**: 20,000
+- **LB-M**: 50,000
+- **LB-L**: 160,000
+- **LB-XL**: 3 million

 ## Private Load Balancer
 
 A Load Balancer is defined as private when you choose the "private" [accessibility](#accessibility) option during Load Balancer creation. A Private Load Balancer has no public IP address, and only listens to requests or connections sent through the Private Network(s) to which it is attached. Read more about private Load Balancers and their characteristics and limitations in our [dedicated documentation](/load-balancer/reference-content/public-private-accessibility/#private-load-balancers).

 You can view your Load Balancer's metrics and logs by using [Scaleway Cockpit](/cockpit/quickstart/). Load Balancer is fully integrated into Cockpit, and allows you to monitor your Load Balancers frontends, backends, and backend servers at a glance, and visualize your metrics, traffic and logs. This page explains how to get started with Scaleway Cockpit for viewing your Load Balancers metrics and logs.

A value of 20 means that each backend server will have a limit of 20 connections (even if, for example, there are only three servers in the backend). This setting is particularly relevant when using the [First available](#balancing-method) balancing method.

       - Pass the request/connection to a different backend server that still has slots available, unless no backend server has available slots in which case the Load Balancer indicates to the client that the request cannot be handled (e.g. `503 service unavailable` for HTTP or connection closed for TCP), or
