In the latest, and perhaps largest, entry into the world of mashup compeitions comes the Amazon Web Services Start-up Challenge. The AWS team is "searching for the next hot start-up that is leveraging AWS to build its infrastructure and business".
As the AWS team announced they will award a "first-place prize of $50,000 in cash, $50,000 in Amazon Web Services (AWS) credits, mentoring sessions from an AWS technical expert, and an investment offer from Amazon.com. Four second-place winners will receive $5,000 in AWS credits and all qualified contestants receive up to $25 in service credits". Judging will be based on "originality and creativity of the idea, likelihood of long-term success, how well it addresses a need in the marketplace, and implementation of pay-as-you-use Amazon Web Services. Finalists will be announced in November and Amazon will produce a video of each finalist to post on aws.amazon.com where the community can vote for their favorite start-up." The deadline for entries is October 28th.
Besides the new infrastructure services like the EC2 API and the S3 API, Amazon's mainstay E-Commerce API remains very popular. We have 182 shopping mashups built with it including the recently added Price Cut Review shopping service that shows only Amazon products that are half the retail price or lower.
