Each cloud-native evolution is about using the hardware more efficiently. The global cloud computing industry was valued at $371 billion in 2020. Network effects are not the same as monopoly control. Cloud providers incur huge fixed costs for creating and maintaining a network of datacenters spread throughout the word.

In addition to the default Docker namespaces (mount, network, UTS, IPC, and PID), we employ user namespaces for added layers of isolation. For example, the PID namespace makes it so that a process can only see PIDs in its own namespace, and therefore cannot send kill signals to random processes on the host.

Thanks to progress in networks and browsers (but not devices), a more generous global budget cap has emerged for sites constructed the "modern" way: ~100KiB of HTML/CSS/fonts and ~300-350KiB of JS (compressed) is the new rule-of-thumb limit for at least the next year or two.

It's time once again to update our priors regarding the global device and network situation.

When even a bit of React can be a problem on devices slow and fast alike, using it is an intentional choice that effectively excludes people with low-end hardware.

Also, the amount of data that is required for the page, and the complexity of the route it must travel through, will determine the amount of carbon released by the network itself.
