NodeWeaver is a new kind of hyperconverged appliance-bringing together storage, networking and virtualization, completely self-managing and designed to be simple to operate and exceptionally reliable. We have chosen from the start to take advantage of the OpenNebula orchestrator as our main component, a choice driven by its simplicity, reliability and its open design and development process. Our choice has been demonstrated, over and over, an excellent one: OpenNebula simplicity has been extremely appreciated by our customers, and the modularity of its architecture substantially reduced the complexity of adapting and extending it. In three years of experimentation, and several mission critical deployments, OpenNebula has exceeded all our expectations.
