I've not posted for a while, happy with CF/S3 performance - a happy camper as they say.....

However, something has always "bugged me" about CF/S3, and that is the need to create an origin-server side sync method to update S3/CF when dynamic content on an origin server is added (or existing content expires in the CDN - pull only from S3, etc).

For example, if you have a site where users upload their avatars, you need to sync with S3, either in near-time (best) or batch to keep S3 current. The same is true for any site with dynamic content. It is a lot of unnecessary extra work to initiate this on the origin service side, when it can be initiate from the client-user side.

In fact, I just noticed that SimpleCDN offers this service.... during a discussion at the link below, titled /clientscripts over to Amazon S3/Cloudfront?

/clientscripts over to Amazon S3/Cloudfront? - vBulletin.org Forum

And in particular, this reply to someone who introduced the SimpleCDN feature in the discussion thread:

vBulletin.org Forum - View Single Post - /clientscripts over to Amazon S3/Cloudfront?

I have been informed that SimpleCDN does have a feature where, if a file is
required from the CDN and it is not yet uploaded, SimpleCDN will pull it from the origin server. This is a very good feature and we are considering to try it now because of this. (!!)

Also, I note that S3/CF do not have this functionality (presently) and is not currently on the AWS roadmap.

I think this feature is critical now, especially them more I think about it. In fact, it is a "game changer".... as folks can move to the CDN and then (effortlessly)"on demand" populate the CDN by having the CDN (or S3 in the AWS case) pull from the origin server. Also dynamic changes to any site means almost "zero configuration" and no requires sync / upload to the CDN... and yea this is goodness for all!

As a fan of Amazon CF/S3, I would like to see this feature soon. More than likely, we will move some user-dynamic content over to SimpleCDN because of this feature that, if effect, works like "cache-miss, pull from origin server"). Very user friendly.... and also aligns with "the spirit of the Internet".... (like DNS, etc. where content is cached and pulled from the origin server when not available, cache timeouts, etc.) Having S3 as "the final frontier" is sub-optimal.

Right now, it is (1) Try CF, if CF does not have a file, (2) pull from S3, if S3 has no file, return "file not found" (404 I guess...) .... Better would be:

(1) Try CF, if CF does not have a file (2) pull from S3, if S3 has no file, (3) try origin server, if origin server has not file, then return "file not found".

Or, if you really want to serve AWS customers, offer this option..... :-)

(1) Try CF, if CF does not have a file (2) pull from origin server, if origin server has not file, then return "file not found" (or try S3 .... :-)

I assume that AWS wants to require people to store in S3 and will not permit CF to pull from the origin server..... OK... business is business, but please permit, at least, S3 to pull from origin server.

I will update some stats from our SimpleCDN tests soon.

NAME

       rdf2bin, rdf2com - convert an RDOFF object file to flat binary

SYNOPSIS

       rdf2bin [-o relocation-origin] [-p segment-alignment] [-f format] input-file output-file
       rdf2com [-p segment-alignment] input-file output-file
       rdf2ith [-o relocation-origin] [-p segment-alignment] input-file output-file
       rdf2srec [-o relocation-origin] [-p segment-alignment] input-file output-file

OPTIONS

       -o relocation-origin
	      Relocate	at origin relocation-origin.  If invoked as rdf2com, the default relocation origin will be 0x100. Else, the default origin
	      is 0.

       -p segment-alignment
	      Pad segments until their size is a multiple of segment-alignment.  By default, 16 is used.
