SPECI, a simulation tool exploring cloud-scale data centres

TL;DR

SPECI is a simulation tool designed to explore and predict the performance and scaling behavior of future large-scale cloud data centers, addressing the lack of existing predictive tools in this domain.

Contribution

The paper introduces SPECI, a novel simulation tool for analyzing the scaling and performance of future cloud data centers, accounting for non-linear properties and failures.

Findings

SPECI enables detailed exploration of data center scaling behaviors.

The tool helps predict performance issues in future large-scale data centers.

It addresses the gap in existing tools for performance prediction of cloud infrastructure.

Abstract

There is a rapid increase in the size of data centres (DCs) used to provide cloud computing services. It is commonly agreed that not all properties in the middleware that manages DCs will scale linearly with the number of components. Further, "normal failure" complicates the assessment of the per-formance of a DC. However, unlike in other engineering domains, there are no well established tools that allow the prediction of the performance and behav-iour of future generations of DCs. SPECI, Simulation Program for Elastic Cloud Infrastructures, is a simulation tool which allows exploration of aspects of scaling as well as performance properties of future DCs.
