Cloud computing refers to storage and processing that occurs in a networked environment rather than relying on the limits of a personal computer. In the cloud, storage and processing resources are allocated “on the fly” among consumers based on their specific needs. The result is shared content that is less expensive to store, easier to manage and access, and often more true to the dynamic nature of knowledge that emerges from university settings. The cloud has been of tremendous interest to Australia and New Zealand for some time, but concerns over the legal jurisdiction and continued availability of data stored on offshore servers is leading to the development of private, Australian clouds that offer the same benefits.
Overview
Cloud computing is the practice of using networked computers to distribute storage, processing power, applications, and large systems among many machines. To the end user, the cloud is invisible; it is simply the back-end platform that supports everyday applications, both web-based and desktop. Resources and storage in the cloud are allocated as needed in response to the level of demand at any given time, allowing applications to scale dynamically to support user loads of different sizes. Cloud-based applications appeared in the 2008 report on the near horizon, and indeed, many of the applications highlighted in that report have been integrated into educational practice already. However, as experience with the technology has grown, it has become clear that cloud computing poses unique challenges for audiences in Australia and New Zealand. The solution to the most vexing of these challenges is increasingly seen as combining the resources of educational institutions into cloud clusters, known informally as “private clouds.”
A key factor in the mix is that, irrespective of how the cloud is configured or where it is located, there are a number of clearly positive capacities inherent in cloud computing. Cloud-based applications are always up to date and there are no demands placed on local support staff to make that happen. The same is true when project and other shared sorts of documents are stored in the cloud; a number of cloud-based applications allow workgroups to collaborate in ways that automatically track changes and present the latest versions to users.
Cloud computing is also valued for the elasticity of resources it affords. Institutions and commercial entities that use the cloud to support complex computing demands, storage, and media streaming need not worry about over- or under-provisioning for necessary services, since the available resources Cloud computing refers to storage and processing that occurs in a networked environment rather than relying on the limits of a personal computer.

These benefits are naturally very attractive, but in Australia and New Zealand, they are tempered by concerns related to the physical location of cloud resources. Nearly all of the large data farms available for cloud-based applications are currently located in North America, Asia, or Europe, which poses problems for Australians concerned with the sovereignty of their information. Questions about who has legal control of data stored on computers in another country are not easily answered, making it a challenge to use the cloud to store or work with confidential, sensitive, or private information such as student records, health histories, financial data, and so on.
To address the issues around using existing clouds, Australian companies — and international companies that do significant business in Australia — are beginning to establish private clouds located within the country to house their customers’ data. For example, Blackboard, an American company, has established an Australian data centre to serve its customers there. Local providers like Infoplex (http://www.infoplex.com.au) offer secure, private cloud services to their clients using servers that are physically located within Australia. Enterprise software solutions such as Microsoft’s web-based Office 2010 can now be set up and configured to run in private cloud environments, combining the flexibility of cloud-based productivity tools with the security of a privately-controlled cluster.
Companies like Cisco Systems are encouraging the Australian and New Zealand governments and major educational organisations to establish private clouds within and among institutions, and to experiment with notions like hybrid clouds, which would use local clouds for processes and data that have needs tied to physical location, and external clouds for processes where there is less concern around data sovereignty. Advances in the ways networks are locally configured are making such approaches easier all the time; the creation of local cloud clusters, for example, has been spurred by advances in how they are configured and administered. Support for private clouds is on the very near term horizon, via open source cloud platforms such as Eucalyptus or OpenNebula.
Relevance for Teaching, Learning, and Creative Enquiry
Cloud computing in all its forms offers wide ranging benefits for education in the form of software and hardware management, data-driven research, and flexibility of resources. Private clouds offer the promise of truly personalised computing environments, complete with all the tools and resources one needs, accessible via the Internet on a wide range of devices located anywhere.
Access to scalable computing resources on demand means institutions will have a much wider range of choices regarding how they balance the cost of provisioning their networks with the research needs of their departments. University data centres, in particular, are uniquely poised to maximise their resources by creating local clouds on their own networks. For institutions that do not have a large computing infrastructure, the cloud allows researchers to easily and relatively inexpensively scale their computing needs up or down as the demands of their work require. In the not-so-recent past, neither of these scenarios was really possible. Such benefits apply across the range of cloud configurations under discussion.
The move toward private clouds physically located in Australia and New Zealand — and particularly in educational institutions there — is seen as a critical component of a larger effort to establish a national network of research data. Also called the national data fabric, this network would be supported by a series of Australian cloud clusters. Organisations such as the Australian National Data Service (ANDS) are being established to promote and realise the vision of an Australia-wide research data network. Such a data fabric promises secure and locally administered access for Australian scholars and researchers pursuing enquiries in virtually every discipline, and is a major driver of interest in private clouds.
A sampling of applications of cloud computing and private clouds across disciplines includes the following:
- Biotechnology. The Medical College of Wisconsin Biotechnology and Bioengineering Centre in Milwaukee produced a set of free tools called ViPDAC (Virtual Proteomics Data Analysis Cluster) to be used with Amazon’s cloud computing service to determine the elemental composition as well as chemical structure of a molecule.
- Computer Science. Students at the University of California, Berkeley, use cloud computing resources to perform load testing measurements as they learn how to design datacenter-scale applications. Each pair of students is able to access 8-10 virtual servers to make their own observations — nearly 200 servers are used per class. Once the lab is over, the servers are released.
- Professional Development. A trial project at Continuing Education Bendigo in Victoria, Australia known as RSSing Organisational Capacity aims to use RSS to collate information and coursework about learners so that teachers and trainers can quickly assess prior learning and current needs. The project is supported by the Australian Flexible Learning Framework.
