When your business launches a major advertising campaign, the last thing you want is a website crash under heavy visitor traffic. ‘502 Bad Gateway’ or ‘504 Gateway Timeout’ errors mean direct financial losses and angry customers. Professional server maintenance prevents these problems.
Server management (DevOps/SysAdmin) includes configuring operating systems, usually Linux Ubuntu/Debian, optimizing Nginx or Apache web servers and tuning PostgreSQL, MySQL or MongoDB databases. A properly configured server can handle tens of thousands of simultaneous requests even with affordable resources.
Security is the second important aspect. Unprotected ports, outdated packages and weak passwords make servers easy targets for bots. Configure a UFW firewall, SSH key access with password login disabled, and Fail2ban to automatically block suspicious IP addresses.
Monitoring systems such as Zabbix, Grafana or UptimeRobot watch availability 24/7. If server load approaches a critical threshold for any reason, engineers receive an instant alert and fix the problem before users notice anything.
