processes and avoid data competition, that is, how to enable a good cooperative operation of multiple processes. Example: (from Baidu Encyclopedia) Take the operation of a parking lot as an example. For simplicity, assume that there are only three parking spaces in the parking lot, and the three parking spaces are empty at the beginning. At this time, if there are five vehicles at the same time, the gatekeeper will allow three of them to enter direct

And this is the core of zone allocator.Before formally introducing zone allocator, we will introduce some surrounding affairs.1.

Varnish is an HTTP accelerator that can act as a load balancer and cache the contents, which can then be delivered at lightning speed. Facebook uses Arnish to process photos and profile pictures and handle billions of of daily requests. Like everything else, varnish is open source. Other things that keep Facebook running smoothly We have mentioned the software that makes up the Facebook system and helps to run on a large scale. However, dealing with such a large system is a complex task, so
