Nuxis is an integrated solution for virtualization management. Some of its features are centralized management of nodes/physical machines and virtual machines, management of virtual networks, storage management, ISO management, monitoring and statistics charts, backup/restore of appliance configurations, import from and export to other virtualization systems using the OVF format, access control, support for multiple operating systems on 32-bit and 64-bit architectures, including Linux and Windows, paravirtualized hardware acceleration drivers, live migrate, PXE boot, Web management, storage management with LVM, and more.
Makeflow is a workflow engine for executing large complex applications on clusters, clouds, and grids. It can be used to drive several different distributed computing systems, including Condor, SGE, and the included Work Queue system. It does not require a distributed filesystem, so you can use it to harness whatever collection of machines you have available. It is typically used for scaling up data-intensive scientific applications to hundreds or thousands of cores.
OpenSVC is a 'service' manager, as in clustered service manager. Services are described as collections of resources (IP, disk groups, filesystems, file synchronizations, and application launchers). Services can be started, stopped and queried for status, providing a consistent command set for wildly different service integrations. Services can be administered using a stand-alone free software stack deployed on the nodes (nodeware). Service configurations, status, and logs are pushed to a central database coupled to a Web front-end (collector).
wsrep-enabled MySQL (previously MySQL/Galera cluster) can use wsrep replication providers, such as Galera, to form a cluster. wsrep API is an abstract replication interface that supports global transaction ID, true multi-master capability, conflict detection and resolution, and parallel applying and is transparent to triggers, stored procedures, and functions by replicating only final transaction results. Only the InnoDB storage engine and DDL commands are supported by this patch.
