Distributed Load Testing Tool - Backend

Introduction

This repository houses the backend components of the distributed load testing tool designed to simplify advanced performance testing. The backend is developed using the Go programming language, following a master-slave architecture to efficiently manage load testing operations.

Technology Stack

• Go: Primary programming language.
• RabbitMQ: For communication between backend nodes.
• REST API: For interfacing with the front end.
• Socket.IO: For real-time communication with the front end.
• Docker: For containerizing the backend services.
• Kubernetes: For orchestrating the containers, hosted on Digital Ocean.

Architecture

The backend adopts a master-slave architecture where:

• The Master hosts a REST API and a Socket.IO server, facilitating communication with the front end and managing the slave nodes.
• Slave nodes perform the load tests as directed by the master, with coordination handled via RabbitMQ.

Installation and Setup

To set up the backend using Docker:

1. Ensure Docker and Docker Compose are installed on your machine.
2. Clone the repository:

git clone https://github.com/Jake4-CX/CT6039-Dissertation-Backend.git

3. Navigate to the project directory:

cd load-test-backend

4. Use Docker Compose to start the services:

docker-compose up -d

This will pull the latest images for the master and worker nodes from jake4/loadtest-master:latest and jake4/loadtest-worker:latest and start the necessary services as defined in the docker-compose.yml.

Usage

Once the services are running, the master node will be available at http://localhost:8080, providing access to the REST API and the Socket.IO server. The backend is also set up to communicate with slave nodes through RabbitMQ for distributing tasks.

Deployment

For deploying the backend to a production environment:

• Configure the Kubernetes files under /deployments/k8s to suit your deployment needs.
• Use the provided manifests to deploy the backend services on a Kubernetes cluster, such as Digital Ocean's Kubernetes service.
