Clobi is a job scheduling system supporting Virtual Machines (VMs) in multiple Infrastructure-as-a-Service computing clouds. Currently, the system is using and supporting Nimbus (and it’s prepared for Cumulus, Nimbus’ storage service) and Amazon Web Services (more precisely EC2, SQS, SimpleDB, S3).
Here you can find a visualization of the system.
It’s an “elastic” and “scalable” job system that can set up a huge computing resource pool almost instantly. VMs are added to or removed from the pool dynamically; based on need and demand. Jobs are submitted and processed using an asynchronous queueing system. An arbitrary number of clients is allowed to submit jobs to an existing resource pool. The basic reliability is inherited from the reliability of the core messaging components Amazon SQS (for queueing) and Amazon SimpleDB (for bookkeeping): to prevent data from being lost or becoming unavailable, it
