Bob-Web Services / HTTP services are not built to be the primary backend of your flex applications. Because they are XML based, they have quite a bit more overhead than flex's built-in AMF (Action Message Format). AMF is smaller, faster and uses less bandwidth than XML. AMF is what FDS and ColdFusion 7.0.2 use to communicate to a Flex app.
Does Adobe have any stats on this? Was wondering as I found otherwise in a simple test
copy paste from a old thread:
old thread here...but...I just built a example app for my team here to share some Flex luv. Its a simple plain-jane datagrid populated with 500 rows from a database. I made three versions of the app:
1) Using remoteobject and typed objects CFC to AS.
2) Using a REST call to return XML via a HTTPService
3) Using a WebService to return untyped objects, Structs.
#2 whipped the pants off 1 and was a bit faster then 3. I was really expecting 1 to be faster with all the AMF talk and all. I suppose 1 has a bit of over head on bith ends though to handle the objects.
So let's say that your question is narrowed down to "FDS or CF?". Adobe's ideal answer is "yes." They are complimentary to each other, CF allows for wonderful rapid development of Flex apps, and FDS brings some amazing features to the table through it's Messaging an Data Management services.Web Services (SOAP) support is in Flex primarily to consume third-party data, allowing you to add it to your app.Hope this points you in the right direction.Shan

Subject: [Junk E-Mail - LOW] [flexcoders] Re: Choice of backend systems - which provides best functionalityFranck,
I appreciate your respons. When you say Remote Objects/Flex Data
Services provides the most advanced way of interoperating with the
backend, what specifically is possible?
What are the capabilities that I would get leveraging Remote
Objects/Flex Data Services that I would not get (or would be difficult
to implement) with Web services or HTTP services. If there are
resources on the Adobe site that spell this out, please point me to them.
Since we are looking at the different possibilities and we have
somewhat of a blank slate, the more I can go into this with open eyes
the better. I appreciate everyone who responded being willing to guide
someone new to this architecture.
Thanks,
Bob
