BESSEMER CLOUD COMPUTING LAW #1:
Less is more!
Leverage the cloud everywhere you practically can, both for your internal systems as well as for your own product offering(s) and "just say no" to on-premises deployments! This will not only give you a direct understanding of the customer experience and best-of-breed strategies of Cloud Businesses, but it will free up your technical resources and balance sheet to focus on your core product and customers.
Although your technical team may be great at setting up Exchange servers and PBX systems, they are far too valuable to your organization to waste their time on such rote tasks. Your cost of capital is also likely very high, making upfront hardware and license costs extremely painful (dilutive) for a young company. By pushing as much as possible into the cloud, you avoid management headaches and make these expenses variable. You should be able to pick many initial products quickly, including hosted email (Gmail, hosted MSFT Exchange, USA.net), CRM (Salesforce.com, Oracle CRM On Demand, Microsoft Dynamics CRM), Marketing Automation or email management (Eloqua, ConstantContact, Vertical Response), Financials (Intacct, NetSuite), Talent Management (SuccessFactors, Cornerstone OnDemand, Taleo, LinkedIn), web analytics (Omniture/Adobe, Google Analytics, Coremetrics), telecom (Verizon, AT&T, Paetec, Smoothstone, Nuvox)Skype, Google Voice, Fonality, etc..), security (Google/Postini, McAfee, Symantec, Perimeter eSecurity), webcasting/remote access (Webex, GoToMyPC, LogMeIn, TeamViewer), and the like.
Similarly, try to leverage PaaS and IaaS whenever possible for your own core product development. There has been a massive change in the consumer internet world over the last two years, with the vast majority of new internet websites and applications using Cloud environments such as Amazon Web Services as the foundation of their development from the first day. We believe that quality of service and portability issues are rapidly resolving themselves at a level that will be suitable for enterprise deployments, and a similar migration will occur within the software and Software-as-a-Service worlds over the coming years. Although trends in Cloud businesses tend to be more predictable than those in consumer internet traffic
