Best Practices for Running Nexus Browser-Based Farming Applications
Best Practices for Running Nexus Browser-Based Farming Applications
This article details the optimal server configuration for hosting Nexus browser-based farming applications. These applications, relying heavily on JavaScript execution and persistent WebSocket connections, demand specific server resources and configurations to ensure stability, performance, and scalability. This guide is geared towards newcomers to server administration within our Nexus infrastructure.
Understanding the Requirements
Nexus browser-based farming applications are characterized by the following:
- **High Concurrency:** Many users simultaneously controlling numerous virtual farms.
- **Persistent Connections:** Each user maintains an open WebSocket connection to the server for real-time updates.
- **JavaScript Intensive:** Significant client-side processing, requiring a robust server to handle associated requests and data transfer.
- **Database Interactions:** Frequent reads and writes to the database to manage farm state, user data, and market information.
- **Real-time Data Streaming:** Delivering rapidly changing data (e.g., crop growth, market prices) to all connected clients.
Hardware Specifications
The following table outlines recommended hardware specifications based on the anticipated number of concurrent users. These are *minimum* recommendations; scaling up is highly advised for peak load and future growth. Refer to the Server Scaling Guide for detailed information on horizontal scaling.
| Concurrent Users | CPU | RAM | Storage (SSD) | Network Bandwidth |
|---|---|---|---|---|
| 1-50 | 4 Cores @ 2.5GHz | 8GB | 256GB | 100 Mbps |
| 51-200 | 8 Cores @ 3.0GHz | 16GB | 512GB | 500 Mbps |
| 201-500 | 16 Cores @ 3.5GHz | 32GB | 1TB | 1 Gbps |
| 501+ | 32+ Cores @ 3.5GHz | 64GB+ | 2TB+ | 10 Gbps+ |
It's crucial to prioritize SSD storage for the database and application code. Traditional HDDs will severely impact performance. Consider using RAID configurations (e.g., RAID 1, RAID 10) for data redundancy and improved read/write speeds. Consult the RAID Configuration Documentation for details.
Software Stack
The following software stack is recommended for optimal performance and compatibility. Ensure all software is up-to-date with the latest security patches.
- **Operating System:** Ubuntu Server 22.04 LTS (or later) - preferred for stability and package availability. See the OS Hardening Guide for security best practices.
- **Web Server:** Nginx - offers excellent performance and scalability for handling WebSocket connections and static content. Configure Nginx as a reverse proxy in front of your application server. Refer to the Nginx Configuration documentation.
- **Application Server:** Node.js (v18 or later) - ideal for JavaScript-based applications. Use a process manager like PM2 to ensure high availability and automatic restarts. See the Node.js Application Deployment guide.
- **Database:** PostgreSQL - a robust and reliable relational database. Proper indexing and query optimization are crucial for performance. Consult the PostgreSQL Optimization article.
- **Caching:** Redis - used for caching frequently accessed data, such as market prices and user session information. This significantly reduces database load. See the Redis Caching Implementation tutorial.
- **WebSocket Library:** Socket.IO or similar - facilitates real-time, bidirectional communication between the server and clients.
Configuration Details
Detailed configuration steps are essential for maximizing performance.
Nginx Configuration
The following snippet illustrates a basic Nginx configuration for handling WebSocket connections:
```nginx upstream nodejs_backend {
server 127.0.0.1:3000; # Replace with your Node.js application's port
}
server {
listen 80; # Or 443 for HTTPS server_name your_domain.com;
location / {
proxy_pass http://nodejs_backend;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
}
# Static files
location /static {
root /path/to/your/static/files;
}
} ```
Database Optimization
| Parameter | Recommended Value | Description | |---|---|---| | `shared_buffers` | 25% of RAM | Amount of memory dedicated to shared memory buffers. | | `work_mem` | 64MB | Amount of memory used by internal sort operations and hash tables before writing to disk. | | `maintenance_work_mem` | 512MB | Amount of memory used by maintenance operations like VACUUM and CREATE INDEX. | | `effective_cache_size` | 50% of RAM | An estimate of the amount of memory available for disk caching. |
Refer to the PostgreSQL Tuning Guide for advanced optimization techniques.
Node.js Process Management (PM2)
Use PM2 to manage your Node.js application. Example PM2 command:
`pm2 start app.js --name nexus-farming --instances 4`
This starts four instances of your application, providing redundancy and improved performance. Configure PM2 to automatically restart the application on failure. See the PM2 Configuration Guide for details.
Monitoring and Logging
Implement robust monitoring and logging to identify and resolve performance issues. Utilize tools like:
- **Prometheus and Grafana:** For collecting and visualizing server metrics.
- **ELK Stack (Elasticsearch, Logstash, Kibana):** For centralized logging and analysis.
- **New Relic or Datadog:** For application performance monitoring (APM).
Regularly review logs for errors and performance bottlenecks. Refer to the Server Monitoring Best Practices article.
Security Considerations
- **Firewall:** Configure a firewall (e.g., UFW) to restrict access to only necessary ports.
- **HTTPS:** Always use HTTPS to encrypt communication between the server and clients.
- **Regular Security Audits:** Conduct regular security audits to identify and address vulnerabilities. Consult the Server Security Checklist.
- **Input Validation:** Implement strict input validation to prevent injection attacks.
