Note that approach (a) changes the sending a chat message / loading a Facebook page from a one-to-one communication into a multicast to all online friends, while approach (b) ensures that users who are neither chatting nor browsing Facebook are nonetheless generating server load.Another challenge is ensuring the timely delivery of the messages themselves.The naive implementation of sending a notification to all friends whenever a user comes online or goes offline has a worst case cost of O(average friendlist size * peak users * churn rate) messages/second, where churn rate is the frequency with which users come online and go offline, in events/second.This is wildly inefficient to the point of being untenable, given that the average number of friends per user is measured in the hundreds, and the number of concurrent users during peak site usage is on the order of several millions.If you still need some more stunningly unique facts...In almost two decades we have never resorted to inserting advertisements into our HTML enabled chat application. It has always been free to use and has never required any registration to join and if you do decide to register, it is and will always be free.We chose to simulate the impact of many real users hitting many machines by means of a "dark launch" period in which Facebook pages would make connections to the chat servers, query for presence information and simulate message sends without a single UI element drawn on the page.With the "dark launch" bugs fixed, we hope that you enjoy Facebook Chat now that the UI lights have been turned on.
The result of running out of Apache processes over the entire Facebook web tier is not pretty, nor is the dynamic configuration of the Apache process limits enjoyable.
The way this is typically accomplished in a web application is by separating the model and the view: data is persisted in a database (perhaps with a separate in-memory cache), with each short-lived request retrieving only the parts relevant to that request.
Because the data is persisted, a failed read request can be re-attempted.
Our chat application has been active since the year 2000, long before the creation of today's social media sites and even before myspace came on to the web-world scene.
It has been used on some of the most desirable domains the internet has to offer (See the Poo. In addition to those rare factors, our chat also supports the use of the Hypertext Markup Language being posted and parsed directly into the chat!
