Abstract UniteCloud is a cloud-computing platform developed in Unitec Institute of Technology to provide a solution to resilient infrastructure and data services. UniteCloud has been constructed using OpenStack with its peak computational capability up to 500 virtual machines and maximum storage allocation 64 tera-bytes per virtual machine. The resiliency of UniteCloud is achieved by three novel components. CloudViz-3D is a top-level interactive cloud monitoring system that monitors the running status of cloud and notifies users before any disaster occurs. rRVM is a low latency and high consistency high availability system that generates real time backup and disaster recovery. CRaaSH is an offline disaster recovery system that provides decentralized service checkpoint/restart over commodity networks. In addition, the platform supports group collaborative working, editing, big data processing and machine learning algorithmic experiments with its open source implementation of Gitlab, ShareLatex, HadoopDataCenter and TensorFlow. With all its resilient service features, UniteCloud is specializing in supplying eLearning and eResearch services for New Zealand tertiary students and staffs.
