Five years ago, C12G Labs initiated the OpenNebula.org open-source project aimed at developing the industry standard solution for building and managing virtualized enterprise data centers and cloud infrastructures. As an open source solution for data center virtualization, the OpenNebula is considered feature-rich open-source alternative to proprietary cloud solutions.

In an effort to provide users with the most-demanded functionalities for enterprise clouds with a single install and to provide all those functionalities comparable to VMware vCenter and vCloud Director, OpenNebula.org has released the latest version - OpenNebula 3.4 with advanced features.

According to the company, the OpenNebula 3.4 is the most stable version delivering enterprise-class functionality, stability and scalability with broader platform support and integration capabilities for KVM, Xen and VMware hypervisors.

Distributed under Apache license, the OpenNebula features an adaptable and extensible architecture, interfaces and components that help in building customized cloud service or product. Tested through an internal quality assurance process and by a large community, it provides a comprehensive solution for data center virtualization management from private to public clouds unlike other open-source solutions that focus on public cloud features.

As a widely-deployed open-source management solution for enterprise data center virtualization, the OpenNebula 3.4 focuses on extending its storage capabilities with the support for multiple datastores to offer flexible, scalable and high performance storage backends.

Incorporating all key functionalities for cloud computing, storage and networking with a single install, the OpenNebula reduces cost and complexity of the cloud, and ensures its long term stability and performance through a single integrated patching and updating process, and one-stop support.

"While being hypervisor-agnostic, this new update of OpenNebula has functionality comparable to VMware vCenter and vCloud Director", said Ruben S. Montero, chief architect of OpenNebula, in a statement.

Ignacio M. Llorente, director of OpenNebula, said in a statement, "This eleventh stable release leverages power of user-driven development by delivering a production-proven product that comprises the most-demanded functionalities for enterprise clouds with a single install."

As the most feature-rich open-source alternative to VMware datacenter and cloud suite, the OpenNebula 3.4 provides cloud consumers with a choice of interfaces, from open cloud to de-facto standards, like the Amazon API.

According to a press release, the new release brings countless valuable contributions from many industry members of its large user community, including Research in Motion (News - Alert), Logica, Terradue 2.0 and CloudWeavers, and from research and academia, especially Clemson and Vilnius Universities.

In addition, the OpenNebula 3.4 also features improvements in other systems, such as support for resource pools, elastic IPs in the Amazon API, improved web GUIs, and better support for hybrid clouds with Amazon EC2. 

In January, OpenNebula 3.2 was released reported TMCnet.
