Editor's Note: This post is the first in a three-part series on the benefits of Google Apps’ cloud-computing architecture.

“Cloud computing” has become a trendy buzzword, and some traditional technology vendors are even using the term though their solutions are still rooted in legacy architectures. In this three-part series, I’ll share how Google’s multi-tenant, Internet-scale architecture and browser-based applications produce three key advantages: the fastest innovation, improved reliability and security, and maximum economies of scale. Today I’ll focus on how Google’s innovation exceeds what’s possible with on-premises technology, single-tenant hosted applications, and “software plus services”.

Faster access to innovation for higher productivity
The web is the epicenter of innovation, and Google’s multi-tenant infrastructure is designed so we can push improvements to our entire customer base on short iteration cycles. We can deliver new functionality on a weekly basis, or faster, because our systems are able to distribute updates so efficiently. In 2009 alone, we launched over 100 improvements, and customers didn’t need to manage any upgrades or patches. In contrast, businesses tend to update traditional server software every five to seven years due to long release cycles from vendors and the cost and complexity businesses face implementing upgrades, especially when more powerful servers are required, like 64-bit hardware.

Browser-based applications are another key ingredient in our recipe for rapid innovation. When we launch new features to our web applications, users automatically get these improvements just by refreshing their browsers. Our mobile browser applications also get new features without software updates. With traditional technology and “software plus services”, client software is an innovation bottleneck. Even after back-end systems can support new features, users don’t get new functionality in those environments until the software on their computers and mobile phones have been upgraded, which can be an expensive and labor-intensive project.

Feedback and anonymous usage statistics from hundreds of millions of users in the real world also help us bring stress-tested innovation to business customers at an unprecedented pace. From our consumer user base, we quickly learn which new features would be useful in the business context, refine those features, and make them available to Google Apps customers with minimal delay.

Continuous innovation powered by the cloud has another advantage over traditional technology cycles: employees adapt to a continuous stream of manageable improvements better than they tolerate large, disruptive batches of change. Gradual iterations in bite-sized chunks substantially reduce change-management challenges. Conversely, employees are subjected to a painful re-learning cycle each time companies upgrade traditional software.

Dramatically faster innovation helps employees be more productive, but that’s not all Google’s cloud has to offer. In part two of this series, next week I’ll focus on how Google Apps can offer better security and higher reliability than on-premises technology, single-tenant hosted applications and “software plus services”.

If you’re interested in going a level deeper, we invite you to geek out with us on Thursday, April 22nd, when we’ll be holding a webcast to explore the advantages of Google’s cloud. Hope you can join us!
