Top ten advantages of Google’s cloud
Compared to on-premises, hosted and “software plus services” technologies, Google’s multi-tenant, Internet-scale infrastructure offers faster access to innovation, superior reliability and security, and maximum economies of scale.

Google has been pushing the technological bounds of cloud computing for more than ten years. Today, feedback and usage statistics from hundreds of millions of users in the real world 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.
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 in 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.
Rapid 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.
Web-based applications powered by Google’s global infrastructure give workers full access to their information across devices, so they can be productive in more places. Their data is stored in the cloud – not on one particular computer – so employees can connect with all of their information and get work done from any Internet connection. Google’s infrastructure gives users seamless access to their information at work, at home, on the road and from their mobile devices. With traditional technology, important information can be trapped in software only available on a limited set of devices, preventing employees from being their most productive.
Because data in Google Apps is stored in the cloud instead of on employee computers, multiple users can access and contribute to projects simultaneously without worrying about using the same operating system, software, or browser. For example, instead of collaborating on a document by sending back and forth revision after revision as attachments, documents are stored in the cloud with Google Apps. Coworkers can access the web-based document simultaneously in their browsers, and even make changes that other authorized users can see in real-time. Eliminating attachment round-trips by storing data in the cloud saves time and reduces frustrations for teams who need to work together efficiently.
Google’s large investments in physical and process-based security are passed on to customers. First, Google is able to hire many of the worlds leading security experts to protect our systems and conduct cutting-edge security research. Our data centers are hardened with many of the latest measures in security precautions, including biometric access controls and multi-tiered security perimeters. Furthermore, Google has implemented a multi-layered security process protocol designed to help keep customer data safe. Our processes have been independently verified in a successful third-party SAS 70 Type II audit to verify our confidentiality, integrity and availability of customer data. Finally, Google is able to efficiently manage security updates across our nearly homogeneous global cloud computing infrastructure, so customer aren’t exposed to known vulnerabilities until they install security patches themselves.
Browser-based applications also help keep sensitive data more secure. Unlike traditional software, when a user is finished using a web-based application, minimal data is left on the machine that could be compromised. Also, when employees can securely access their data from any browser, they’re less likely to store data locally on unsecured end-points like thumb drives. In a world where one out of ten laptops go missing in the first year1 and 66% of workers report having lost a thumb drive2, making data securely available from the browser and minimizing the amount of sensitive data stored on devices is an effective security strategy.
Through synchronous replication, data and user actions in Google Apps are mirrored in nearly real-time across multiple data centers. If one data center becomes unavailable for any reason, the system is designed to instantly fall back to a secondary data center with no user-visible interruption in service. For Google Apps customers, our recovery point objective (RPO) design target is zero, and our recovery time objective (RTO) design target is instant failover. Gmail, Google Calendar, Google Talk, Google Groups, Google Docs and Google Sites have a 99.9% uptime guarantee, and our actual reliability has been significantly higher than this commitment. Attempting to replicate this level of reliability with on-premises or hosted technology is tremendously costly and complex. Even very large enterprises with state-of-the-art disaster recovery systems typically target a recovery time of one hour and accept the loss of one hour’s worth of data.
Moving to Google’s cloud doesn’t mean you lose control of your data or your technology. The Google Apps Terms of Service explicitly state that customers retain ownership of their data in Google Apps, and Google firmly believes that customers should be able to easily get their data out of Google Apps if they ever decide to stop using the service. Furthermore, Google Apps provides controls so administrators can manage which applications their users can access and how employees can use each service. Finally, Google Apps APIs allow administrators build custom functionality and integrations with other technologies.
Google buys raw computer parts in massive quantities, and assembles custom servers with few unnecessary components. Not only do we save costs on hardware, we also minimize overhead by consolidating on a very small number of server configurations that can be managed in bulk globally at an extremely efficient ratio of staff to machines. On a per-user basis, these economies of scale allow Google Apps to operate at higher levels of efficiency than can be achieved by customers themselves. Further cost savings are also made possible by applications that run in the browser. Customers save time and money because there’s no specialized software to license, patch and periodically replace.
