Prevention strategies include: 1. Robust monitoring: Implement real-time monitoring of server resources (CPU, RAM, disk I/O, network) and application performance. 2. Optimize application code: Ensure database queries are efficient, and long-running processes are handled asynchronously. 3. Proper timeout configuration: Set appropriate timeouts for web servers, application servers, and databases. 4. Sufficient resources: Provision servers with enough capacity to handle peak loads, or use auto-scaling solutions. 5. Load balancing: Distribute traffic across multiple application instances. 6. Regular maintenance: Keep software updated and review logs for early warning signs.
