The cost to deliver an application to an end-user has dropped dramatically for these companies and the cost to operate their data centers therefore has much less of an impact on their costs of operations and capex budget than it used to, which means their gross margins for delivering their product have improved significantly since 1995. For companies like Yahoo, Google and more recently, Technorati, this means the cost to deliver a page view or search results page has gone down dramatically, while the average size of a search-results page is perhaps only marginally larger since 1995. Even considering the size of a search index (Google’s 8B pages today vs. Excite’s 10M in 1995) has grown nearly one thousand-fold, the costs of computing power and storage have accommodated this expansion while bandwidth costs and rack space have fallen nearly tenfold.
For enterprise-focused companies like Salesforce.com, Postini, Quova and Rally, the story is similar. Add in a subscription-based recurring revenue stream and you have a business model that has all the benefits of a dependable revenue stream and profit margins that can approach those of a traditional software company. Thanks to the low cost and high performance of today’s hardware coupled with an elegant service architecture, Postini is able to process several hundred million email messages per day for its customers with an extraordinarily light hardware footprint and does so quite profitably as a result.
