Distributed computing. Generally more loosely coupled than a cluster. A grid may be heterogeneous and geographically dispersed.
Cloud computing infrastructure provides the ability to provision computing infrastructure, software, storage, security and data management as a service. Typically this is provided using distributed virtual systems preconfigured to perform these services. When greater throughput is required, more virtual machines are provisioned to support the load.
Commercial Cloud computing efforts are available as services purchased through vendors such as Amazon Web Services (EC2: Elastic Computing Cloud) or Google AppEngine.Open source cloud frameworks are also available:
- OpenStack.org - control large pools of compute, storage, and networking resources using a web dashboard
- Eucalyptus.cloud - mimics the Amazon Web Services cloud and API
- AppScale - provides compatibility with Google App Engine Applications
- CloudFoundary.com - EMC VmWare supported project
- CloudStack.org - Apache foundation sponsored. Java based. VM Hypervisors supported: VMware, Oracle VM, KVM, Xen.
- Nimbus - Amazon EC2/S3-compatible. Targeted to the scientific community.
- OpenQRM - works with Debian, Ubuntu and CentOS Linux and VMware, Xen, KVM and Citrix XenServer virtual machines. Supported "Enterprise" edition available. N to 1 HA failover.
- FOSS-cloud.org - Linux or MS/Windows - desktop support focus
- Myrinet - High speed low latency interconnection. Switch interconnect.
- Dolphin Interconnect - Ring topology. Also 2D and 3D topologies. Traffic shared on ring. If one node goes out, the ring is broken and communications stop.
