Instead of scaling up, where you buy more powerful and expensive hardware, you scale out by having more servers processing messages. Every server basically competes for messages, doing their best to process as many as they can. Although the servers can scale out, they have no knowledge of each other.

Latency can be roughly defined as the time it takes to send a packet from point A (say, the client) to point B (the server). This is one of the main reasons why content delivery networks (CDNs) exist: They place servers physically closer to the end user in order to reduce latency, and thus delay, as much as possible. and prior (a)).
