Finally, let's talk about queuing.
0:03
We are not going to cover queuing in this class,
0:06
but if we are taking the survey of the range of possible ways
0:10
of communicating with services, queuing probably shouldn't be left out.
0:13
So queuing is typically done sort of behind the firewall, right,
0:16
so I've got a set of apps they are running behind the firewall,
0:20
one of them is going to get some sort of operation,
0:23
it's going to add some kind of work or message to the queue
0:27
later on asynchronously another app that might pick that up and do something,
0:32
so for example, hey I am a web server, will you send an email to this person,
0:35
and I am going to carry on serving at my web pages.
0:38
Some other sort of email work or process might grab that go yeah sure,
0:42
I will start the outbound email campaign to this person.
0:45
That is queuing, we are not going to cover queuing in this class,
0:48
but just to round down the spectrum there you have it.
