4. Monitoring and Performance Tuning: Keeping track of server performance is essential for maintaining optimal functionality. Tools like Nagios or Zabbix allow administrators to monitor various aspects such as CPU usage, memory utilization, disk space availability, network traffic analysis, and more.


5. High Availability & Load-Balancing: When downtime in mission-critical environments is not an alternative, high availability solutions are a must. Apache mod_proxy_balancer, or HAProxy, are technologies that enable load-balancing between multiple servers. This ensures redundancy while also distributing incoming requests equally.


6.


Database Administration: Many applications rely on databases for storing data efficiently. Understanding how to install and administer databases such as MySQL or PostgreSQL, is crucial for managing web applications.
