Welcome to the final lesson in our series. By the end of this article, you’ll understand key techniques to harden and speed up your Nginx-powered applications. We’ll cover:
Objectives
| Feature | Benefit |
|---|---|
| Rate limiting | Protect against DDoS, brute-force logins, and web scraping |
| Caching (Nginx) | Reduce backend load and improve response times |
| Compression (Gzip) | Decrease payload sizes without extra software |
| Keep-Alive connections | Maintain persistent client–server connections |
| Log analysis & troubleshooting | Identify errors and performance issues via access and error logs |
| System monitoring (Datadog) | Gather continuous metrics and alerts with Datadog |
Note
Effective performance tuning requires balancing resource usage and user experience. Always test changes in a staging environment before deploying to production.
In the sections that follow, you’ll learn how to:
- Configure rate limiting to throttle abusive traffic.
- Set up Nginx caching directives for static and dynamic content.
- Enable Gzip compression and fine-tune its parameters.
- Optimize keep-alive settings for long-lived connections.
- Parse Nginx logs to pinpoint and resolve errors.
- Install and configure Datadog for real-time monitoring.
