The text discusses a method of delegating resource-intensive tasks to more powerful machines only when necessary in web applications. It provides an example using Next.js, where the application is split into two process groups: one for accepting HTTP traffic and handling most requests (web), and another for performing heavy lifting (worker). The solution involves creating a route that performs the resource-intensive task, a wrapper function to delegate tasks between web and worker machines, and defining the process groups and Machines in the fly.toml configuration file. This method can improve application performance by offloading demanding tasks to more capable resources when needed.
