iCE is a tool that aims to interactively run experiments on a dynamic list of cloud instances (VMs or containers). iCE takes no assumptions on how many are the available instances are, where are these instances located and what is going to run on them.
iCE is composed of three main parts. The first is the iCE registry, an HTTP server that is hosting the database of instances. This database is changing rapidly as instances terminate (leave the pool) or boot (join the pool).
The second component the iCE agent is a small program that runs on a cloud instance and takes care of registering it to the iCE registry. For instances created through iCE's integration with EC2, the iCE agent runs automatically on instance boot.
The third component is the iCE client. The client is a set of services that enable experimentation on the registered instances. These services can be used interactively with the iCE shell, or programmatically through the iCE client Python API.
An experiment is a standard Python file that defines two types of actions. These are the iCE runners and the iCE tasks. When these actions are invoked from an iCE client (shell or Python API) they run against every instance that has joined the instances pool.
This repository defines the iCE API and includes the core functionality, as well as, the iCE registry. The other components can be found in:
