RunJRun is a very simple system for doing parallel processing in Java, using Amazon Elastic Compute Cloud (EC2) instances as compute nodes. The basic compute unit is a Runnable, Serializable Java object, a "task" for short. A user submits a list of such tasks to RunJRun. Each task then has its run() method invoked on an EC2 instance. To use it, you'll need an Amazon Machine Image (AMI) that has the RunJRun server-side software installed; several such AMIs are available.
LASIC is a language that facilitates creating and managing systems in a cloud environment. It allows you to create scripts that describe a system, its components, and the relationship between those components using a declarative syntax. Various verbs can then be applied to the script such as deploy (create a new system), shutdown, or runAction(run some action on components of the system). LASIC currently supports Amazon's cloud environment (AWS). LASIC stands for Language for Automating Systems in the Cloud.
