AMF is a format for serializing ActionScript objects in 
a compact binary form - it is used in a number of places in the Flash Player. It 
is not, in itself, an API that makes connections but rather something 
that can be used over connections to represent 
data.
 
For example, flash.net.NetConnection can make either 
HTTP or RTMP based connections and ActionScript data sent via either one of 
these protocols uses AMF for the encoding. For HTTP based communications AMF 
formatted requests and responses are made but the connection is not 
persistent. For RTMP based communication a connection is maintained to allow for 
real-time communications so that data can be "pushed" from the server to the 
client.
 
flash.net.Socket is a simpler or, rather, more raw API 
that allows you to create your own persistent connection but leaves the protocol 
and communication format up entirely up to you. With the ability of 
flash.utils.ByteArray to serialize ActionScript objects using AMF you could also 
use AMF if you wanted to on your Socket so long as the endpoint understands this 
format.
 
If you don't have any requirements to push data to the 
client, it is unlikely that you'll need to use an API like 
Socket.
 
Note that for "webservices" in the WSDL/SOAP sense, AMF 
is not really relevant. In the broader definition of a web service, AMF is used, 
for example, by Flex's RemoteObject feature to send and receive ActionScript 
data from a remote endpoint, such as ColdFusion or Flex Data 
Services.

AMF vs Socket?


What is the difference between AMF and Socket connections?Is AMF 
itself a socket connection that does the serialization ofwebservices on a 
'standard' port?Is there constant chatter over the line when using AMF 
or socket? Bychatter I mean, does the server and client continually check 
that theother exists after the connection is established?I doubt 
I'll ever run into making my own socket but I see it broughtup from time to 
time and just wanted to know I'll still use AMF in theend when I can, but 
I'd like to know how it works vs the other 
options:)Thanks
