History
How we got here provides valuable lessons for building your product and scaling it globally. The retail business is peaky. Amazon needed capacity to meet its highest demand period during Thanksgiving and Black Friday. Come January, it had a whole lot of hardware sitting around, underutilized. Having worked for years providing e-commerce services to partners, they were able to take their internal offerings and make them available to the public. Utility computing was born.
This pattern has been repeated many times. Amazon is constantly adding services to tackle new and unique problems that they have encountered within their own business. Those internal services then get previewed and customer feedback is collected. When they meet a certain service level, they're released for use by anyone with a credit card. You need to use this same strategy for your products.
