• Coming soon 
RPC
• remote procedure call (RPC) is an inter-process communication that allows a computer program to
cause a subroutine or procedure to execute in another address space without the programmer
explicitly coding the details for this remote interaction.
Serialization
• serialization is the process of converting a data structure or object into a sequence of bits so that it
can be stored in a file or memory buffer, or transmitted across a network connection link to be
"resurrected" later in the same or another computer environment.
RTMP
• RealTime Messaging Protocol (RTMP) is a proprietary protocol developed by Macromedia
for streaming audio, video and data over the Internet, between a Flash player and a server.
RTMPS
• which is RTMPT over a secure SSL connection using HTTPS
AMF - SomeTerms

3. “Action Message Format (AMF) is a compact
binary format that is used to serialize ActionScript
object graphs” From: AMF 3 Specification

What is AMF

4. • AMF was introduced in Flash Player 6 in 2001
• Remained unchanged until AS2 Flash Player8
•This version of AMF is referred to as AMF0
• In Flash Player 9, Action Script 3.0 – AMF3 with
new data types and optimization
•AMF3 Specification
AMF History

5. Size of AMF Object.
Fast serialization / de serialization.
AMF is parsed directly to an object.
Native Type and custom class support.
Low bandwidth and CPU
•Compared with HTML JSONYAML XML (SOAP)
Send Object By Reference (AMF 3)
Benefits (why use it?)

AMF/Remoting vs. Web Services Benchmark

7. No DisplayObject (and descended objects)
Native Types and Custom class.
Compression (zlib)
Pitfalls

8. Binary format
• Hard to read
Complex Backend
• Server errors influence client
• Server side elopers needed
Organization learning curve.
AMF is not the answer for all the problems.
Downsides

9. Client side
•Flash platform – build in support
•Other open source reversed engineered
Servers side:
•Depend on technology (PHP, Java .net, Ruby on
Rails…).
•Depend on platform (Windows Linux Unix).
•Depend on knowledge.
