A LAMP stack refers to a set of open-source software used for web development. It consists of Linux as the operating system, Apache as the web server, MySQL as the database management system, and PHP as the programming language. This combination forms a powerful platform for building dynamic websites and web applications.
Importance of Monitoring and Troubleshooting
Monitoring and troubleshooting are crucial aspects of maintaining LAMP applications. As these applications serve critical functions for businesses and organizations, any downtime or performance issues can result in significant losses. Monitoring helps in identifying potential issues before they escalate, while troubleshooting ensures swift resolution of problems to minimize downtime.
