When Google launched its web-based e-mail service (Gmail) on April 1, 2004, many people thought it was an April Fool's Day joke, and perhaps with good reason. That same day, the company had posted plans to open a research facility on the moon. \nRELATED LINKS\nAnalysis: Salesforce's Addition of Google Apps Shows Google's Intent to Enter Business Software Market\n\nCan Google Apps Crack the Fortune 500 and Large Enterprises?\n\nCapgemini Will Watch Your Back on Google Apps\n\nThe moon project was a joke. But people quickly realized that Gmail was for real, and the service would serve as the foundation for the company's launching of Google Apps, a free set of messaging and collaboration applications, including e-mail (Gmail), calendar, documents & spreadsheets, presentations, instant messaging (Google Talk), a wiki (Google Sites) and a start page (iGoogle). \n\nSince launching an enterprise version of Google Apps in February 2007 for $50 per user per year, Google entered a competitive landscape inhabited for decades by the likes of Microsoft and IBM, both of whom offer office productivity software and corporate e-mail systems.\n\nBut it hasn't been an easy road for Google Enterprise (the name given to the division of the company that oversees Google Apps). According to Jonathan Edwards, an analyst with the Yankee Group, Google has faced reluctant IT departments (and their CIOs) who see Google Apps as a consumer product, out of touch with the realities of providing the proper security, support and reliability businesses require in enterprise software.\nGoogle Fights Reputation as a Consumer Juggernaut as Corporate IT Resists Adoption\nThis perception about Google's consumer orientation among corporate IT departments runs deep when it comes to e-mail. A recent survey by CIO of more than 300 IT decision-makers found that only 18 percent of respondents would consider a hosted e-mail service like enterprise Gmail. More than 50 percent said they wouldn't consider it at all, and cited "security reasons" as the main barrier.\n\nFor these prospective customers, the decision of whether to adopt Google Apps in the enterprise is as much philosophical as technical. According to Edwards, many companies balk at the idea of letting their data (especially e-mail messages) be stored outside their company's walls and in Google's data center. They worry it will put them at odds with compliance laws such as Sarbanes-Oxley, which requires companies be ready to have their data audited and know the exact location of it.\n\nAnalysts say it's a challenge Google has sought to address through the acquisition of a security vendor (Postini), which provides such services as archiving and message encryption. Google also offers its customers service level agreements (SLAs) and IT roadmaps (a projection of how the technology will progress over time), characteristics inherent in a typical contract between a software vendor and a company buying their product.\nGoogle Apps Makers Believe Time (and IT Value) Is on Their Side\nGoogle officials acknowledge this challenge of convincing corporate IT departments that they can be a business software provider. But leaders at Google Enterprise and Google Apps believe they will win the good graces of large business over time for the same reasons other SaaS (software as a service) vendors, such as Salesforce.com, did years ago. \n\nAccording to Dave Girouard, President of Google Enterprise, software delivered over the Web (or "the cloud") like Google Apps allows IT departments to realize substantial cost savings by having fewer servers to maintain and seamless upgrades to the applications which don't require IT or end-users to ever hit a button. \n\n"IT resources are scarce at any company, and with the people you have, they shouldn't be managing e-mail servers," Girouard says. "Those people ought to be working on things that are special and proprietary, things that help you win over competitors."\n\n\tIn addition, Gmail's popularity among consumers could cause users to rise up and call for its adoption in large organizations, what the authors Charlene Li and Josh Bernoff of Forrester Research call a "Groundswell".\n\n\nRebecca Wettemann, vice president with the consultancy Nucleus Research, sees the potential uprising, too. "Users begin to ask, 'Why is this easier at home than at work?' " says Wettemann. "Many software firms are trying to leverage what's going on in the consumer space and bring it to users at businesses. Google is very well-positioned to do that."\nGoogle Apps to Microsoft Office: We Come as a Friend, Not a Foe\n\nThe spread of Gmail and Google's overall popularity as the web's top search engine made the launch of Google Apps an interesting alternative for businesses to consider: what if you could pay little or nothing for online software and get document and spreadsheet capabilities similar to what you used to pay Microsoft many dollars for with Office?\n\n\nMicrosoft CEO Steve Ballmer and chairman Bill Gates have downplayed Google Apps' importance, dismissing it as not being a true competitor. Both have noted that Microsoft Office applications such as Word and Excel offer more features than Google Apps.\n\n\tGirouard and other Google Apps leaders have two responses to such statements: First, in the context of large enterprises, Google views its productivity software as a supplement, not a replacement, to Microsoft Office. Only in the case of Gmail and calendaring, he concedes, does Google Apps present enterprises and their users with a choice.\n\n\t"It's around e-mail (and calendars) where you have co-existence issues with Google users and non Google users," he says. "With docs, it tends to no really be an issue because people are just using both [Google Apps and Office] and they use what makes sense for a particular task."\n\nSecondly, Google isn't focused on the quantity of features it can embed into the product. Instead, it's focused on letting users collaborate online in real time. In other words, it doesn't matter to Google whether a person composes content in the Google Apps interface or Microsoft Word. \n\n\t"Google Apps is used alongside other applications, and we believe that will increasingly be the case," says Girouard. "In the cloud-based model, there will be more vendor choice and mixing and matching rather than standardizing on a single vendor."\n\n\tWith respect to features, the people designing and managing Google Apps say they focus on getting each feature right for the user rather than packing in new, or half-baked, functions into the software for the sake of it. \n\n\t"It's not about the application with 503 features beating the app with 502 features," says Rajen Sheth, product lead for Google Apps. "I think it's more about the app with 15 really solid, really useful features."\n\t\nThe Flavors of Google Apps\nConsumer: Any person who has a Gmail account has access to the consumer version of Google Apps. This includes the key functions (Gmail, Calendar, Docs & Spreadsheets, Talk and Google Sites). Ads run along side many of the applications to subsidize the user's free experience. Each user gets 6.7 GB of storage.\nStandard: This is utilized by many small and medium sized businesses and is also free (with ads). It has everything found in the consumer version, but it enables companies to use their own e-mail address (instead of @gmail) and has mobile access, an administrator control panel, e-mail migration tools, and online support. \nPremier: For $50 per user per year, it includes 25 GB of storage per user and no ads. Aside from all the features of the standard version, it has e-mail security provided by Postini, and it comes with APIs that allow organizations to integrate Google Apps with enterprise single-sign on systems and e-mail. It also includes 24-hour phone support. \n\n\nThe Security and Compliance Question: Getting Comfortable with Google\n\tGoogle's philosophy around information security is fairly simple: your data is safer with Google than it is with you. \n\n"That's sort of bold and right in the face of what people object to with SaaS, but to be honest, that's the truth," Girouard says. "We've had intelligence agencies of the United States government tell us that: 'we think our data would be safer with Google than it is on our own servers.'"\n\nAs Google offers prospective customers a deeper look at its security under non-disclosure agreement, it's impossible to know what those agencies found so appealing. On a more practical level, however, analysts say Google's acquisition of Postini, a security vendor, has helped in their efforts to show that they are serious about keeping enterprise data safe. The Google Apps premier edition has a Postini console to manage messaging security.\n\n"Postini has helped Google Apps a bit," says Edwards. "Postini has a proven security product that many businesses have trusted."\n\n\nGoogle also received a \nStatement of Auditing (SAS 70) certification, which requires a close examination of the company's internal security controls. Such certification has been seen as an important step for SaaS companies showing customers they're in line with compliance standards, especially Sarbanes-Oxley, Edwards says.\n\n\nWhile Google officials like Girouard are bullish on the business value of their online applications, analysts say the company's high profile among consumers makes it more difficult to win over IT departments than other SaaS companies have faced in the past. \n\nNuclues Research's Wettemann says that people wonder if their enterprise data could somehow come up on a search by a regular consumer using the Google search bar. \t"A lot of it is perception," Wettemann says. "You look at what they do with Google Health, and people wonder, 'will people be able to Google me and find my health records?' The answer is of course no, but it takes people [and businesses] some time to get over that idea."Google's Partnership with SaaS Vendor Salesforce.com\n\tTo help win the enterprise hearts and minds, Google has tapped into the expertise of one company who has shown that SaaS is just as safe as on premise software: Salesforce.com, which sells customer relationship management (CRM) software and delivers it to business users over the Web. \n\nBack in April, Google and Salesforce.com entered into a partnershipthat made a basic version of Google Apps available for free to any Salesforce.com customer who wanted it. The deal has opened up new sales channel for Google Apps to be sold to businesses.\n\n\t"It's been great because Salesforce.com has been at this for a lot longer than we have," Girouard says. "The joint selling is great, and it'll be a nice symbiotic relationship."\nThe Upside to Google Apps' Open Design\nGoogle Apps has largely been designed based on Google's overall philosophy that the Web should be open to consumers and businesses to use as a platform for creating new applications. As a result, Google Apps utilizes a lot of open Application Programming Interfaces (APIs) that allow third-party developers to build on top of it. \n\nThe advantage to this strategy is that it helps Google add features to Google Apps that its developer and engineering teams, which focus on core functions of the software, might not otherwise have time to create. An example of this occurred recently with Google Spreadsheets. \n\n\tSheth and his Google Apps project team focus primarily on what he calls the 80 percent use case \u2014 meaning, he wants to build the application so that for 80 percent of users at a company, it has all the features they would need. So when people complained the Spreadsheets didn't have a pivot table capability, he let the openness of the Google Apps platform do its work.\n\n\t "Pivot tables is kind of a power-user functionality, so it's not something we'd go to as the first thing we'd build," Sheth says. "But now we have a pivot table that was actually built by a third party that extends the functionality of spreadsheets."\n\n\tThe third-party was a vendor called Panorama, which focuses on Business Intelligence (BI) software. It used \nGoogle Gadgets, which allows people to build or place applications on top of Google Spreadsheets. By tapping the abilities of third-party developers, analysts say Google can keep the product innovative and less static.\n\n\n\tAccording to the Yankee Group analyst Edwards, Google's ability to build a developer community could help them like it did for Microsoft years ago in creating an ecosystem of developers around Windows. Last week, Google held a conference in San Francisco and outlined its plans for investing in third-party developers. "If you get a developer community behind you, you can get new and innovative stuff daily," Edwards says.\n\nPart of this picture also includes, for Google, the fact that Google Apps makes no presumption that it is your only enterprise vendor, says Sheth.\n\nThey have built tight integration with existing e-mail and calendaring systems such as Outlook and Exchange and will continue to hook into more systems moving forward. Google Docs & Spreadsheets can import and export files to PDF, Office files, or openoffice.\n\n\t"One of the core philosophies we want to push is that we don't assume we're the only thing out there," Sheth says. "These applications are built to assume that they'll work with apps customers already have, both in the cloud, and on premise."\n It's Social\n\tTraditional e-mail and productivity tools for businesses have typically been anti-social. For instance, if a user composed a document on Microsoft Word, the ability to share it with colleagues in real-time has been fairly limited. At most organizations, the tendency would be to e-mail it around to coworkers, or, if the company used Microsoft SharePoint or Office Live, they could check it in and out of a central repository.\n\n\tWith Google Apps, the idea of sharing, even with basic productivity tools, takes a front and center stage. With Google Docs, for instance, users edit and modify the document online and the changes happen in real time. \n\n\tGoogle also recently added social software such as wikis to the Google Apps portfolio. Google Sites, as it's called, allows people in businesses to use the wiki technology (which Google originally acquired from a start-up vendor Jotspot) to build websites and intranets with no programming experience. \n\n\tAs all these tools get thrown into Gadgets, and moved across various applications, Sheth believes users can build their business and personal connections more efficiently. \nThe Google Way: Rapid Development and Release\n\n\tLike older, more established vendors (think of IBM and Microsoft), Google does offer service level agreements and IT roadmaps (customers and partners must sign non-disclosure agreements to see the details). But Google differs in its approach to software development cycles from older vendors who make major application software changes every year or two. In the Google model, minor changes get made incrementally but happen with greater frequency. \n\n\t"What we have the luxury to do as a cloud-based platform is to do things iteratively," Sheth says. "Many of our products have two- or four-week cycle increments."\n\n\tThat rapid development and release cycle may be good for Google, but it's not clear how IT departments will like that pace, says Tom Austin, a Gartner analyst, who notes that Microsoft and IBM will give detailed roadmaps that look a year or more into the future. "Google, on the other hand, will give a six month [roadmap] and they'll talk broadly about 'directions' after that," he says.\n\n\tAustin notes that this is due to the fast pace of online software development and the fact that Google gets so much feedback from consumers using its products. Even so, Google has been cautious about what features it adds to Google Apps.\n\n\t"I don't think they are aiming for perfection," Austin says. "They are aiming to avoid a big stinking mistake. They will iterate from release to release. They want to make sure they don't add something that's confusing and turns people off."\n\n\n\tOne other philosophical adjustment that enterprises must make: Google does just a bare minimum when it comes to offline functionality. While its Google Gears API yielded an offline mode to Google Docs & Spreadsheets back in April, an offline version of Gmail still doesn't exist for Google Apps users. \n\nSeeing as Google products work best online, the company has turned more of its attention to encouraging the ubiquity of wireless technology. It bid $4.6 billion in the FCC's 700 MhZ wireless auction, only to withdraw after making sure the rules required that the winner be open to all devices and accompanying applications (Google Apps anyone?). \nThe Consumer Consumes the Enterprise\nIt should seem appropriate that Gmail and later its accompanying Google Apps started as online tools for consumers. After all, Google philosophically has built its search business on the collective intelligence of Web users: if a website page is popular and relevant, Google recognizes it and presents it up high in its search results.\n\t\n\tWhile Google does face the challenges voiced by what analysts describe as IT departments worried about their enterprise data being stored alongside consumer data, Google views its straddling of the enterprise and consumer spaces as a competitive advantage.\n\nGirouard says he talks a lot about this subject with Google founders Larry Page and Sergey Brin, and describes it as a quest for technological relevance in modern life.\n\n\t"I spend more time with Larry and Sergey on that topic than anything else: how do you make technology that recognizes that we are consumers and workers all in one person?" Girouard says. "How can I recognize that my life has become increasingly blended? I should have one calendar because I only have one day. What's the point of having separate calendars? I should have one unified view of my life."\n\n\tGoogle has been particularly successful in this "blending" with iGoogle, a personalized portal where, using Google Gadgets, people can add widgets that blend both their consumer and enterprise diets. For instance, they might have one widget that displays documents they are editing with colleagues along side another widget displaying YouTube video or New York Times headlines.\n\n "Getting this right for the user will be incredibly valuable," Girouard says. \n"We're in a unique position to do that because it's hard for either a pure enterprise company to do that and it's hard for a company that's all in the consumer world to do it."
