Question

Please explain me which of two is secure, powerful one, fast enough on sending to and receiving requested data from the server in Flex!

I prefer working with remoting object with AMFPHP rather than HTTPService

Answer 1

AMF(Remote Objects) – Why its Better

• It’s a binary protocol .
• But its still encapsulated in HTTP so there is no concern with
  firewalls or client issues and we can use our normal web debugging
  methods.
• HTTP headers with a binary body.

HTTP/1.1 200 OK
Date: Tue, 28 Jun 2011 12:55:26 GMT
Content-Type: application/x-amf
Server: stackoverflow.com

(binaryamf body here)

• Because it is binary, it can use pointers.
• -Circular References
• -Objects only transmitted one time.
• Common Strings, for example, are only sent once, then all other
  references to that string only contains a pointer, instead of being
  re-transmitted.
• Same behavior for all Objects.
• Its Transmitted binary format (spec) is the same format as how the
  Flash player stores its objects into memory.
• -No de-marshaling (expensive)
• -No de-serializing
• -Bits from HTTP stream flow ~> into Flash Player Memory
• James Ward Census Data
• -A flex application that is built to use several different transport
  mechanisms while transferring the same data. Show comparative timings
  of each stage of data transfer.
