InfoWorld's top picks of the year in open source platforms, infrastructure, and management software The best open source data center and cloud softwareSlowly but surely, the shape of the data center is changing — and maybe not so slowly. The push is on to close the distance between development and production, and to bridge the gap between private data centers and the cloud. These open source projects are leading the way.AppScaleOne of the most striking developments in the cloud world has been the re-creation of proprietary cloud architectures — the AWS APIs, for instance — via open source. One of the latest projects, AppScale, reproduces Google App Engine using nothing but open source components. What’s more, it runs on a wide variety of existing cloud hosts, ranging from Amazon EC2 to Microsoft Azure to, yes, Google Compute Engine. Apps written in Python, Go, PHP, and Java are all supported. AppScale (the company) has promoted AppScale (the project) as a way to back up apps from Google App Engine or to provide an easy exit strategy from Google’s cloud.
