The Cloud Research Simulation Toolkit (CReST) is a discrete-event
cloud computing simulation platform written in Java. CReST was developed
to address the need for a robust simulation
modelling tool for research and teaching of data centre management and
cloud provision. CReST is a stand-alone application, written in Java,
and is freely available open source (GNU GPLv3). CReST has a unique
feature set that enables simulation at multiple abstraction levels:
from physical hardware, energy usage and thermal flows within a DC, to
networked infrastructure and the virtualisation layer of application
services supporting dynamic user demand.
Design:
CReST is designed as a set of coupled modules that can be
independently switched on or off depending on the level of
abstraction required. Modules include:
- Thermal: Heat generation, propagation and
extraction within the DC.
- Energy: Energy used by DC hardware.
- Failures: Permanent & temporary hardware failures.
- Replacements: New hardware specifications.
- Subscriptions: Middleware subscription network.
- Services: Scheduling and allocation of VMs.
- Pricing: Operational costs and pricing of services.
- Demand: User demand and cloud brokerage.
- UserEvents: User-defined events input via a text file.
- GUI: Real-time display.
The flexible and extensible architecture of CReST enables new modules
to be added, and current modules to be extended, as necessary.
