 # Introduction
-
 No matter what type of server you have (localhost or remote), you need the following requirements.
-
 - Connectivity
-
   - SSH connectivity between Coolify and the server with SSH key authentication.
      ::: success Tip
      Your public key should be added to **root** user's `~/.ssh/authorized_keys`.
-     If you do not have an SSH Key, you can generate on through Coolify with a simple button or you can generate one manually.

      :::
-
-
 - Docker Engine (24+)
-
 ## Types
-
 - **Localhost**: the server where Coolify is installed.
 - **Remote Server**: could be any remote linux server.
-
 ## Localhost
-
 To be able to manage the server where Coolify is running on, the docker container of Coolify should reach the host server through SSH.
-
 You can use localhost as a server where all your resources are running, but it is not recommended as high server usage could prevent to use Coolify.
-
 ::: success Tip
   You can use our [Cloud](https://app.coolify.io) version, so you only need a server for your resources. 
 
   You will get a few other things included with the cloud version, like free email notifications, s3 storage, etc based on your subscription plan.
 :::
-
 ## Remote Server
-
 You can connect any type of servers to Coolify. It could be a VPS, a Raspberry PI or a laptop running Linux.
-
 ::: success Tip
 If you don't have a server or server provider yet, we prefer to use Hetzner.
-
 You can use our [referral link](https://coolify.io/hetzner). It will help us to keep the project alive.
-

-
 ### Cloudflare Tunnels
-
 You can also set to use Cloudflare Tunnels for your servers.
-
 ::: success Tip
 Coolify does not install cloudflared on your server, it needs to be done prior.
-
 All it does is to add the right ProxyCommand (`ProxyCommand <ip / hostname> access ssh --hostname %h`) to all ssh connections.

-## Features
+## Multiple Server Configuration
+When setting up multiple servers in Coolify, it's important to understand how traffic routing works:
 
-### Disk Cleanup threshold
+- **Independent Proxy Handling**: Each server runs its own proxy that handles incoming requests for applications deployed on that server.
+- **Direct Traffic Flow**: Traffic for applications deployed on secondary servers goes directly to those servers, not through the main Coolify server.
+- **DNS Configuration**: You must point your domain DNS to the IP address of the server where the application is deployed, not to the main Coolify server.
 
-You can read more about Automated Cleanup and the disk cleanup threshold in the [Automated Cleanup](/knowledge-base/server/automated-cleanup) section.
+### Role of the Main Server
+The main Coolify server:
+- Provides the management UI to control applications on all connected servers
+- Performs SSH connections to secondary servers for deployment and management
+- Conducts health checks and monitoring
+- Does NOT route or proxy traffic to applications on secondary servers
 
-### Wildcard Domain
+This architecture reduces latency and improves application performance by eliminating additional network hops.
 
+## Features
+### Disk Cleanup threshold
+You can read more about Automated Cleanup and the disk cleanup threshold in the [Automated Cleanup](/knowledge-base/server/automated-cleanup) section.
+### Wildcard Domain
 You can set a wildcard domain (`example: http://example.com`) to your server, so you can easily assign generated domains to all the resources connected to this server.
-
 Example: Your application UUID is `vgsco4o`.
-
 If you have the example set, you will get the following FQDN: `http://vgsco4o.example.com`
-
 If you do not have any wildcard domain set, Coolify will generate a [sslip.io](https://sslip.io) domain, which is free & magical domain that you can use anywhere.
-
 In this case, it will be: `http://vgsco4o.127.0.0.1.sslip.io`, where `127.0.0.1` is your server's IP.
 
-## Proxy
+::: success Tip
+When using multiple servers, remember that each application's domain must point to the specific server where that application is deployed.
+:::
 
+## Proxy
 - **Traefik**: Automatically configure Traefik(v2) based on your deployed resources.
 - **Custom/None**: You will configure a proxy manually (only for advanced users).
-
 ::: success Tip
   Soon we will support Nginx & Caddy with fully automated configuration.
 :::
-
 ### Traefik
-
 Coolify uses Traefik proxy by default to create a reverse proxy for your resources.
-
 ::: success Tip
   Traefik only starts when you did not select any proxy for your server and you
   have a domain configured for a resource or your Coolify instance itself.
 :::

 #### Dynamic Configuration
-
-You can always add your own configuration to the proxy settings from Coolify's UI (`/server/<server_uuid>/proxy`).
