Google wants businesses to have faith in the cloud
Published: 14 Jul 2008 17:43 BST
A large number of Google Docs users couldn't use their online word processor or presentations for about an hour last Tuesday. The glitch illustrated not just the trouble with cloud computing, but also the gradual progress so far in making the concept palatable.
Cloud computing, in which software runs not on PCs or company servers but on computers on the internet, requires something of a leap of faith, both technologically and culturally. Those making the move must get accustomed to a reliance on somebody else's computing infrastructure, and that can be scary.
However, guarantees and practical tools are gradually emerging that will probably help ease the transition.
Google, for example, offers a service-level agreement (SLA) promising that Gmail, the online email component of the Google Apps service, will be available 99.9 percent of the time, with service credits extended to paying customers if Gmail dips below that level.
SLAs are coming to the rest of Google Apps.
"We don't have an SLA yet for Google Calendar or Google Docs, but it's something we're moving quickly towards," said Rishi Chandra, product manager for Google Apps. Google wants "to get the same level of reliability for all of Apps", he said.
Google is a major proponent of cloud computing and Yahoo has just formed a cloud computing group of its own. The trend has the potential to seriously redistribute wealth within the computing industry.
There are two broad categories of cloud computing.
The first category involves online applications such as Google Apps, Yahoo's Zimbra for email, Zoho for office and business software, Adobe Buzzword for word processing and Salesforce.com for managing customer relations.
The second category involves general-purpose foundations such as Amazon Web Services, Saleforce.com's Force.com and Google App Engine, on which customers can run their own applications.
Taking the plunge into the cloud
SLAs are the kind of contractual guarantees that appeal to chief information officers making cost-benefit analyses. But there's a gut-feeling factor at play too.
Psychologically, it's well-known in risk-analysis circles that people feel more comfortable with risk if they feel in control. Thus people are often more comfortable driving a car on a congested freeway than being flown somewhere in a commercial jet, regardless of the relative safety of the two forms of transport.
So, naturally, there's some fear with cloud computing: it means you can't reboot your laptop or check for blinking red lights on the datacentre servers.
Companies are working to address this side of the equation, too. A prime example is the Trust.salesforce.com site, which shows the response time for a Salesforce.com server transaction. It also details when problems happened, what they affected and what caused them.

"We've found, working with our customers, they want transparency. They want to know exactly what's going on all the time," said Bruce Francis, Salesforce.com's vice president of corporate strategy. "If there's an issue, they're not furious; they just want to know exactly what's going on."
Amazon.com, too, offers a basic status report dashboard for Amazon Web Services. "A service dashboard is something our developers asked us for, and we made the service available to them as soon as possible," said spokeswoman Kay Kinton.
'Own your own risk'
Some companies are even trying to make a business out of reducing the uncertainties of cloud computing. One is open-source monitoring-and-management-software company Hyperic, which launched a CloudStatus service in June that monitors Amazon Web Services in greater detail. The company is working hard to extend its monitoring service to other sites, too, including Google App Engine, said Stacey Schneider, senior director of marketing.
"You can't get away from owning your own risk. This is slowing the adoption of the cloud," she said.
Google is trying to communicate better with users and customers, Chandra said, although he stopped short of revealing what the uptime is for Google Docs or detailing exactly why it suffered problems earlier this week.
"With the Docs outage, we posted immediately in the administrative console that there was an issue. We posted to the help centre and the phone-line system that we were working quickly to resolve it," Chandra said.
Asked whether Google plans its own status dashboard, Chandra wouldn't share details but promised better help for users. "We're trying to find even more ways to be more transparent about reliability," he said.
Risks with non-cloud computing
Much ado can and should be made about the risks of cloud computing, but it should also be noted that even the much more mature business of computing outside of the cloud has its risks. Downtime, either through ailing or stolen PCs, or overtaxed or faulty servers, is a serious problem in that field, too.
Those with high-end services boast of 'five nines' of reliability, where services are available 99.999 percent of the year and, therefore, down no more than five minutes and 15 seconds per year. Google's Gmail SLA, at 99.9 percent uptime, promises downtime of less than nine hours per year.
That might not be five nines, and it's for Gmail only at the moment, but Google chooses to see the glass as half full.
"We talk to customers, and 99.9 percent is mostly much higher than most organisations with their internal service today," Chandra said.
