Dataset on Resource Allocation and Usage for a Private Cloud

Introduction

The dataset consists of records collected from a private OpenStack-based cloud operated by the Distributed Systems Laboratory at the Federal University of Campina Grande, Brazil, over approximately one year of operation.

This repository contains sample data collection scripts and R Markdown notebooks for reproducing plots based on the dataset.
