Open-source cloud platforms go to war

Tools

The conflict between backers of rival open-source cloud development platforms is heating up.

Last week, OpenStack supporter Citrix announced it was reviving its own CloudStack cloud under the Apache Foundation. OpenStack retaliated by naming its group of heavyweight supporters, including AT&T, Canonical, HP, IBM, Nebula, Rackspace, Red Hat and SUSE.

Despite their supposed "openness," what these groups are fighting over is ownership of the small and mid-sized business (SMB) market--in everything from converged public/private cloud offerings to vertical software hardware/cloud stacks for big corporate enterprises.

Cloud platform provider VMware, meanwhile, lashed out at the open-source providers in a blog post, calling them the "ugly sisters" and touting its own sprawling customer base and availability.
