Now, there is a lot of chatter around the imminent open sourcing of all its APIs and services and the impact that will have on the other 'clouds' out there — public or private. From the article, "Amazon faces significant threats from open source cloud computing efforts if it pursues a purely proprietary path...Amazon can't ignore the cost advantages and diversity of product offerings that open source players are already offering in the cloud computing space. The company's best move is to open source its tools, which will end up diversifying them, play on a level field in terms of cost with the open source alternatives, and charge for services. Absent these moves, the company will lose potential customers to free, open source alternatives...Word is Amazon's legal team is currently 'investigating' open sourcing their various web services API's including EC2, S3, etc.", although these have not been confirmed by Amazon.
