In one, IT managers said that the most important project their teams are working on for 2015 is cloud computing. And that by 2018, the worldwide market for public cloud services will be worth more than $127 billion, accounting for 'more than half of worldwide software, server and storage spending growth.' The open source community is heavily involved in this cloud trend. Open source technologies provide the foundation for many public cloud services, and many enterprises are using these same technologies to build and hybrid clouds.

In addition, many open source projects offer cloud-based software as a service (SaaS) versions of their applications. This month, we're updating Datamation's list of open source cloud computing applications, which includes infrastructure as a service (IaaS), platform as a service (PaaS), SaaS and other cloud-related offerings. This year, we've added quite a few new projects, including many related to cloud infrastructure, cloud storage and containerization, which isn't surprising given all the growth and interest in cloud technologies. However, it was somewhat more surprising to see that some of the projects with SaaS offerings on last year's version of the list have stopped offering the cloud-based versions of their software.

We'll be watching to see if this trend continues. As always, if you know of additional projects that you think should be on our list, feel free to note them in the comments section below.
