As a web entrepreneur, data storage has always been my nightmare problem. Dreams of critical data wiped out, or just not being able to manage all those servers that store the data, or not being able to serve data fast enough, or...or...
Then along comes Amazon S3, Simple Storage Engine, completely managed storage at $0.15/GB/month storage, with a simple interface that takes literally minutes of programming and wallah you have headache free unlimited storage for your web app.
Already this service is being used by large and famous internet sites, such as SmugMug and WebMail.
Amazon has solved one of the biggest problems on the web today. And they have kept a very low profile about it. I predict that Amazon S3 will go onto to becoming the world's largest data warehousing business, taking away business and revenue from traditional hosts like ThePlanet and Rackspace.
