As the open-source OpenStack community works toward the next major release of its cloud software, announcements such as a new OpenStack Marketplace, as well as products from HP, Internap, SUSE and others, are coming out of the OpenStack Summit in Atlanta.

The summit, running May 12-15, kicked off today with the launch of the OpenStack Marketplace. The marketplace organizes OpenStack cloud product information into five categories: Public Clouds, Distributions & Appliances, Training, Consulting & Systems Integrators, and Drivers. Users can then find and compare products to meet their needs, with the marketplace only including services running a recent version of OpenStack with exposed APIs.

The marketplace, which launched today, featured products from companies and organizations such as Canonical, Dell, HP, IBM, the Linux Foundation, Oracle, Rackspace, Red Hat and others.

Aside from the marketplace launch, several companies rolled out new products and announcements. HP announced it has become a member of the OpenDaylight project, an open-source software-defined networking project sponsored by the Linux Foundation.

HP also launched Helion, a portfolio of cloud products that incorporate OpenStack technology to build and manage workloads in hybrid IT environments. HP plans to invest more than US$1 billion over the next two years in HP Helion.

Other OpenStack Summit announcements included the general availability of Internap’s AgileCLOUD platform, available in the OpenStack Marketplace, which provides integrated virtual hybridization for applications. Cloud infrastructure and Linux provider SUSE also announced SUSE Cloud 3, the first OpenStack distribution with automated high-availability configuration and deployment for building Infrastructure-as-a-Service private clouds.

Two new startups, hybrid enterprise IT platform CloudMultiply and cloud operations automation company StackStorm, also used the 2014 OpenStack Summit to say “Hello World.”
