What is the name of the method in which a task management system is used for their automatic execution?

The method that uses a task management system for automatic execution is called task orchestration. In programming and systems, this is often implemented through job schedulers or workflow management systems.

In Go, for example, goroutines and channels can be used to manage parallel task execution, and for more complex automation, external tools like cron, Airflow, or specialized libraries.

An example of simple automation using goroutines:

package main

import (
    "fmt"
    "time"
)

func task(id int) {
    fmt.Printf("Task %d is running\n", id)
    time.Sleep(time.Second)
    fmt.Printf("Task %d is completed\n", id)
}

func main() {
    for i := 1; i <= 5; i++ {
        go task(i) // start task in a goroutine
    }
    time.Sleep(2 * time.Second) // wait for completion
}

Thus, automatic task execution using a management system is called orchestration.
