Globus Nimbus. Globus Nimbus is an open source toolkit that allows businesses to turn clusters into an Infrastructure-as-a-Service (IaaS) cloud. The Amazon EC2 interface is carried over, but is not the only interface you can choose. Globus Nimbushas just come out with a new release.
Reservoir. Reservoir is the main European research initiative on virtualized infrastructures and cloud computing, according to Ignacio Martin Llorente. He adds: "The aim of this project is to develop the open-source technology to enable deployment and management of complex IT services across different administrative domains. Its open-source approach will support the definition of open standards for cloud computing, breaking the lock-in imposed by vendors today and allowing any organization to build its own local or public cloud infrastructure."
OpenNebula. "OpenNebula is an open source virtual infrastructure engine that enables the dynamic deployment and re-placement of virtual machines on a pool of physical resources," according to project leads. The OpenNebula VM Manager is a core component of Reservoir. "This open-source alternative to commercial tools for VM management provides an efficient, dynamic and scalable management of VMs within datacenters, private clouds, involving a large amount of virtual and physical servers," writes Llorente. "OpenNebula can interface with a remote cloud site, being the only tool able to access on-demand to Amazon EC2 for dynamic scaling the local infrastructure based on actual usage."
It's good to see open source tools and resources competing in the cloud computing space. The end result should be more flexibility for organizations that want to customize their approaches. Open source cloud offerings also have the potential to keep pricing for all competitive services on a level playing field.
