Anso Labs is helmed by Jesse Andrews, the former lead architect at Flock, the Web-browser company that was recently acquired by Zynga, and Soo Choi, a former exec at Booz Allen Hamilton. Anso Labs is best known for its work on the cloud computing front with NASA, the U.S. space agency.

The move takes place against the backdrop of a surge in consolidation in the cloud computing and data center business. Last week, Time Warner Cable dropped $230 million for NaviSite. And on Jan. 28, Verizon acquired Terremark for $1.4 billion. That one-two punch in data center deal-making has led to persistent speculation that other data center companies, Rackspace among them, will be rolled up by larger companies–like Hewlett-Packard, Dell or Cisco Systems–that are eager to add cloud services to their portfolio.

Ask Rackspace executives about this–and I have–and they’ll tell you they’re not thinking about that. Rather than being rolled up by someone else, they’re focused on rolling up the assets they want to grow, and to remain independent. Late last year Rackspace acquired Cloudkick, a start-up focused on building cloud monitoring tools.

Rackspace did $629 million in revenue in 2009, and is expected to show annual sales of about $775 million when it reports fourth-quarter earnings tomorrow. It has 100,000 customers, and while many of them are small- and medium-size businesses, larger enterprise customers like Coca-Cola, Target and Vodaphone are tapping Rackspace for Web hosting and to run their cloud applications.

Rackspace wants Anso Labs for its expertise and devotion to OpenStack, an open-source cloud computing software project backed by Rackspace, Dell, Citrix, Cisco and Canonical, the company behind the Ubuntu flavor of Linux.

Rackspace wants to create a bunch of inter-operable cloud services so that customers can move workload from one cloud service provider to another at will, giving them increased flexibility. It’s comparable in some ways to vCloud from VMware and Eucalyptus.

His latest effort is SnapLogic, which last week landed a $10 million round of funding led by Andreessen Horowitz, with Floodgate Ventures participating.

SnapLogic’s approach to making applications work together is simple. The company has created a common interchange format that gets two or more applications–say, for example, Salesforce.com and ExactTarget–to work together. In both cases, a company can buy “snaps” that get those applications running in the SnapLogic server. Snaps are SnapLogic-ready applications that are available in the company’s own SnapStore.

Before SnapLogic, you could certainly integrate these applications yourself, but not without a lot of heavy programming work. “It can be hard but not impossible,” Dhillon told me. “People often inadvertently paint themselves into a corner. They say, let’s connect these two, and then six months later they want to add NetSuite, and then later they buy another company that runs its own set of applications.”

Dhillon compares the SnapLogic server to a common shipping container. “The shipping industry uses the same container on ships, trains and trucks, and it makes transportation very efficient.” (Investor Ben Horowitz has called Dhillon “the Metaphor King.”) Using the SnapLogic approach allows different applications to fit together inside the same container and share information. So far there are 63 supported apps and some 2,000 supported combinations.

And if that’s not enough, there’s also has an API, so if you have custom applications for which a “snap” isn’t already built, you can roll your own. “Most companies are going to have some element of homegrown software,” he said.

Customers so far include Pandora, Canonical–the company behind Ubuntu Linux–and OSI Restaurant Partners, which owns Outback Steakhouse. ING, the Dutch financial services company, is also running a small installation, Dhillon said.

He thinks of integration as his life’s work, which was only partially started at Informatica. “I have a feeling like there’s this unfinished business I want to tend to.”

Linux on netbooks isn’t going away though. In fact, software and hardware companies have been making big investments to improve Linux netbooks. For the past week, I’ve been using several flavors of Linux running on netbooks — Ubuntu, Hewlett-Packard’s Mi (which is based on Ubuntu) and Moblin, created largely by Intel and not yet available commercially. In all cases, the Linux netbooks failed at some basic functions that any laptop, no matter how tiny and inexpensive, should be able to handle, like working with printers. At the same time, Mi and Moblin have impressive graphical user interfaces well-suited to the habits of typical netbook users, like checking email and accessing social-networking sites, as well as the small screens and low horsepower of tiny laptops. In addition to Linux, all of the computers shared the standard features, or lack thereof, common among netbooks, including compact keyboards and no DVD drives.

H-P’s Mini 110 Mi Edition

The most polished of the products was H-P’s Mini 110 Mi Edition, a new model with a 10.1-inch screen that H-P will begin selling on its Web site for $279.99 on June 10. That’s nearly $50 less than what H-P will charge for the Mini 110 running Windows XP, which will come with a 160-gigabyte hard drive instead of the 8-gigabyte solid-state drive that will come with the Mi edition.

The striking thing about this netbook is the slick graphical user interface created by H-P that runs on top of Ubuntu and first began appearing on H-P netbooks early this year. Instead of a traditional desktop like that found in Windows and the Mac, Mi (pronounced “me”) arranges commonly used applications and content on a screen called the “dashboard,” which looks like a personalized Web page and lists recently received emails, fresh thumbnail images of favorite Web sites, and a Web-search toolbar.

The Mi home screen is a clever way to make the computer seem alive with on- and off-line content, which is fitting since netbooks are designed for on-the-go Internet activities. It’s also tailor-made for the small screen size of netbooks.

A more eye-catching iteration of Linux is Moblin, which I tried out in test form on an Acer netbook; it is expected to ship on netbooks by the end of the year. Moblin has a menu of icons at the top of the screen, the most interesting of which leads to the M-Zone, a home screen that displays calendar appointments and favorite applications alongside snapshots of recently visited sites and a continuous feed from the user’s Twitter network.

An icon called “People” leads to a list of instant-messaging buddies, while another, called “Zones,” let me organize all the applications I had launched into different virtual workspaces, which is useful for hopping between various tasks on a small-screen device like a netbook.

The look and feel of the standard Ubuntu system, without the Mi interface, is more commonplace. I tried out a Dell Mini 10 with a 10.1-inch display and 160-gigabyte hard drive that sells for $349 on Dell’s Web site. The Mini 10 ships with version 8.04 of Ubuntu, which resembles Windows XP, with its desktop, taskbar and pop-up menu system. Ubuntu, in some cases, seemed to overestimate the size of the Dell Mini’s display: A window for configuring wireless-networking capabilities was so large it bled off the screen, and I couldn’t access all the buttons on it. I also installed on the Dell a new version of Ubuntu Netbook Remix, which works better on small screens. Since a Windows XP version of the Dell Mini 10 sells for the same price as the Ubuntu, I can’t see a compelling reason to choose the Ubuntu option.

All the netbooks I tried had compatibility problems with other external devices. The netbooks couldn’t load the software drivers to let me print to my Canon and Dell printers. I couldn’t load pictures over a USB cable from my Canon PowerShot SD750 digital camera. I was able to get my pictures on the machines by plugging a storage card from my camera directly into the netbooks.

Canonical, the London company that oversees development work on Ubuntu, says it is improving the system’s compatibility with various devices. Intel says it is unfair to judge Moblin until it is commercially available.

Some key applications currently don’t run on Linux, like Apple’s iTunes, which makes it difficult to load music files onto iPods from the netbooks. While the Linux laptops didn’t run Microsoft Office, they came with OpenOffice, a free package of word-processing, spreadsheet and presentation applications that allowed me to open and modify basic Word and Excel files.

The companies behind Linux netbooks have made great strides in improving user interfaces, but until they can achieve similar breakthroughs in how the machines work with other devices, Windows netbooks are still a better deal.
