Have you ever deployed your own web application or service in a production environment?

Yes, I have deployed my own web applications in a production environment. The process typically involves preparing the server (e.g., configuring a Linux server), installing necessary components (Java, web server, database), configuring the environment, and deploying the application (via WAR file or Docker container). After that, it is important to set up monitoring, logging, and backup systems to ensure the service's stability.
