Process Management - is the practice of managing multiple concurrent processes that run on a server to optimize resource usage, enhance performance, and scalability for applications (for example, based on Ruby on Rails). When we talk about processes, we may refer to various components such as servers, background processes, or database connections. Managing these processes involves ensuring their efficient operation, distributing resources among them, monitoring server load, and responding to changes in application requirements. For example, sending requests to the database can be organized in such a way as to avoid blocking and optimize response speed, while background processes can be started and managed in a way that does not interfere with the core functions of the application. Process management plays a crucial role in ensuring the efficiency and reliability of application operation. Don't forget about optimizing costs (money) for processes. Continuous monitoring, control, and optimization of processes can significantly reduce infrastructure costs (servers, etc.).
