As Google Reader prepares to enter the great platform beyond on July 1, would-be RSS successor Feedly is making its move to transition "from a product to a platform" by migrating user data (including those hopping over from Google Reader) into its new live cloud service.

In a blog post today, the company said that its previously announced cloud-based infrastructure--the aptly dubbed Feedly Cloud--has officially gone live. Feedly's API can then be tapped into directly by third-party applications such as mobile apps gReader for Android or Newsify for iOS.

In a June 17 blog post, the company announced the beginning of this migration process, which will be a "random rolling update" that should be completed by Friday June 21.

In addition to the new cloud backend, the company also unveiled a completely new stand-alone Web version of Feedly that will play nicely with all browsers, including Opera and Explorer (which had proven to be a bit of a mess).

Gearing up for the end

Feedly has positioned itself as a leading successor for Google's moribund RSS service, attracting millions of former Google Readeratti.

We test drove a number of potential Reader replacements, and--as for now--have found Feedly to be a fitting successor (if not a superior alternative) to Reader. A couple of big names are still waiting in the RSS wings--namely Digg and possibly Facebook.

As Feedly gears up its infrastructure on the back end, it will give the company a noticeable leg-up on some of the RSS also-rans in addition to looming competition from established brand names.
