Load Distrix

Load Distrix is a simple HTTP load balancer written in Go. It distributes incoming HTTP requests across multiple backend servers, ensuring high availability and fault tolerance. The load balancer uses a round-robin algorithm to cycle through the available backend servers, automatically retrying requests on failure and marking unresponsive servers as down.

Features :crystal_ball:

Round-Robin Load Balancing: Distributes requests evenly across backend servers.
Health Checks: Continuously monitors the status of backend servers.
Automatic Retry: Retries requests up to three times in case of failure.
Dynamic Server Pool: Automatically adjusts to backend server availability.

Requirements

Go 1.16 or higher
A configured JSON file named LoadDistrix.config.json with backend server details.

Usage

Clone the repository:

git clone https://github.com/muruga21/LoadDistrix.git
cd loaddistrix

Prepare the configuration file:

write loadbalancer config file in the root directory with the following structure:

{
 "backend": [
   {
     "host": "server1",
     "url": "http://127.0.0.1:8081"
   },
   {
     "host": "server2",
     "url": "http://127.0.0.1:8082"
   }
 ]
 ...continue with your backend configuration
}

[backend]
host="server1"
url="http://127.0.0.1:8081"
[backend]
host="server2"
url="http://127.0.0.1:8082"

... continue with your backend configuration


backend:
- host: "server1"
url: "http://127.0.0.1:8081"
- host: "server2"
url: "http://127.0.0.1:8082"

...continue with your backend configuration


3. Build and run the load balancer:

```sh
go build -o loaddistrix main.go
./loaddistrix <config-file>

The load balancer will start on port 8000. You can now send HTTP requests to http://localhost:8000, and they will be distributed across your configured backend servers.

Configuration :mailbox_with_mail:

To configure loadbalancer, write a configuration file with your choice of file extension. Each backend server should be specified with its `host` and `url`. Example: ```json { "backend": [ { "host": "server1", "url": "http://127.0.0.1:8081" }, { "host": "server2", "url": "http://127.0.0.1:8082" } ] ...continue with your backend configuration } ``` ```toml [backend] host="server1" url="http://127.0.0.1:8081" [backend] host="server2" url="http://127.0.0.1:8082" ... continue with your backend configuration ``` ```yaml backend: - host: "server1" url: "http://127.0.0.1:8081" - host: "server2" url: "http://127.0.0.1:8082" ...continue with your backend configuration ```
