A developer must plan server architecture for current and future needs.
This includes managing multiple servers and preparing for user data growth. Proper server management prevents issues like 'zombie' processes.
A developer uses multiple servers for different parts of an application. Each server has a specific job. For example, one server might run a blog, and another might handle user data. A developer must start servers correctly every time. If a server stops working, the developer must close all related programs. This prevents 'zombie' programs that can cause problems. The developer then checks to make sure the programs are gone before restarting. Over time, a developer merges smaller applications onto fewer servers. This makes the system simpler. Finally, for deployment, all applications can run on a single server using a tool like Gunicorn.
A developer builds an application with three parts: a main application, a user management system, and a blog. The developer runs each part on a separate server. When the developer needs to update the main application, the developer stops its server. The developer uses a command to kill any remaining processes. The developer checks that no old processes are running. Then, the developer restarts the updated main application server. Later, the developer combines the blog and user management system onto one server to save resources.

A developer needs to store many questions for a quiz application. Storing questions in JSON files can be slow.
A developer can follow a plan to reduce server RAM. The plan has three levels.
Before starting a server, a developer must kill all existing instances. After killing, the developer must check that no instances are running.
A developer must always restart the server after any file change. The developer should never tell a user to run the server.
