These days it's hard to talk about enterprise IT without talking about cloud computing. A recent survey found that 33 percent of businesses surveyed were already using cloud computing services and an additional 40 percent were in the planning and evaluation stages of a cloud computing project.
As the corporate world has embraced the cloud, so have many parts of the open source community. Several groups have built open source infrastructure and management tools that allow organizations to set up and maintain a cloud computing environment. In addition, the growing acceptance of software as a service (SaaS) has provided many project owners with a viable way to make money while still adhering to their open source principles.
This month, we're updating our list of open source cloud computing apps that we last published about a year and a half ago. Not surprisingly, our list has grown quite a bit longer as more and more open source projects move to the cloud. Please note that in some cases the "cloud" versions of these applications contain additional features and/or proprietary code that isn't included in the open source version. We included such projects in our list as long as they were largely based on projects with the source available under an open source license.
Feel free to use the comments section below to note additional open source apps that are available on an SaaS basis or that help administrators manage cloud environments.
