Google posted a great article on cloud computing on their Enterprise Blog, including discussion of the advantages of using cloud computing and some information on the design of their data centers.

Key Quotes:

There’s quite a bit of talk these days about corporations building a “private cloud” with concepts like virtualization, and there can be significant benefits to this approach. But those advantages are amplified greatly when customers use applications in the scalable datacenters provided by companies like Google, Amazon, Salesforce.com and soon, Microsoft. 

How much do you spend on maintenance?

According to Gartner, a typical IT department spends 80% of their budget keeping the lights on, and this hampers their ability to drive change and growth in their business. The reality is that most businesses don’t gain a competitive advantage from maintaining their own data centers. We take on that burden and make it our core business so that our customers don’t have to.

The opposite of virtualization:

In the virtualization approach of private data centers, a company takes a server and subdivides it into many servers to increase efficiency. We do the opposite by taking a large set of low cost commodity systems and tying them together into one large supercomputer. We strip down our servers to the bare essentials, so that we’re not paying for components that we don’t need. For example, we produce servers without video graphics chips that aren’t needed in this environment.

Still running an Exchange server?

There is limited value to running an Exchange Server in a virtual machine in the cloud. That server was never designed for the cloud, so you don’t get additional scale. You’d also need to continue to maintain and monitor the mail server yourself, so the labor savings are marginal. But with cloud-based applications like Gmail, we take care of all of the hassle for you. We keep the application up and running, and have designed it to scale easily. All of this provides an application that is roughly less than 1/3 the cost of a privately hosted mail system, has 100x the typical storage, and innovates much faster.
