Yes, the SAAS enterprise applications vendor loves everyone, but none more than Google (GOOG). This morning, Salesforce (CRM) expanded its alliance with the search behemoth, linking its Force.com online development platform to Google’s App Engine. The move essentially allows consumer applications built on Google App Engine to call on data stored in Force.com. And that heralds more robust cloud computing applications, more–and better–alternatives to Microsoft’s (MSFT) core business applications, which are only just now adapted for the cloud.

“The layout is the same, the tabs at the top of the screen are the same, the right-side sidebar listing participants and file uploads is the same,” writes Daring Fireball’s John Gruber. “It even copies Campfire’s trick of formatting a message as ‘code’ if it contains literal newline characters.”

UPDATE: Google has taken Huddle Chat offline. Google Product Manager Pete Koomen offered the following explanation for the move:

As one of the App Engine product managers, I wanted to give an update — we’ve now taken HuddleChat down from the App Engine app gallery. The App Engine team was looking for some sample apps to help kick the tires on their new system, so we invited Googlers to build some as side projects. A couple of our colleagues here built HuddleChat in their spare time because they wanted to share work within their team more easily and thought persistent Web chat would do the trick. We’ve heard some complaints from the developer community, though, so rather than divert attention from Google App Engine itself, we thought it better to just take HuddleChat down.

That seems to be what Google (GOOG) has done with App Engine, a new service for developers who’d like to write and run their Web applications on the company’s infrastructure. With App Engine developers can establish their own little Google Labs outposts, building Google-friendly applications using Google’s own building blocks on the Google File System and Google will handle the scaling and fail-over issues.

That’s a compelling proposition–assuming you want Google to control your entire end-to-end development environment. And who wouldn’t these days? What better way to pique the search giant’s acquisitive interests than building a great big Web 2.0 sandcastle in its very own Web 2.0 sandbox? Who knows, you may be the next YouTube or, at the very least, the next Zingku or Jaiku. And if it turns out that you are, how convenient would it be for Google to acquire you, as Dave Winer noted a while back at Scripting News:

How much would it be worth to buy companies without having to transition their technology to their platform? There would be no retraining either, all the programmers in the companies they acquire would know how to work in the environment. Further, can you imagine that they’d charge universities to teach comp sci using their cloud?

“Given the cost of acquisitons, recruiting and training they can afford to blow a lot of money on free bandwidth, storage and CPU to make the buying and hiring process more efficient and increase the hit rate (the percentage of programmers who work out).”
