Cloud Computing in Institutions

Link: Cloud Computing in Institutions (pdf).

Summary: The term “Cloud Computing” refers to any “computing capability that is delivered as a service over the Internet. While there is no authoritatively accredited definition of the concept, one of the most frequently used definitions is the one given by Gartner, who describe cloud computing as “a style of computing where massively scalable IT-related capabilities are provided ‘as a service’ across the Internet to multiple external

This briefing paper will explain some of the key characteristics and delivery levels of current development and implementations that provide a basis for understanding cloud computing and the ongoing discussion about it.

Using ArchiMate to design learning environment architectures

Link: Using ArchiMate to design learning environment architectures.

Published in International Open Forum Proceedings. 24th ISO/IEC JTC1 SC36 Plenary and WG meetings, International Open Forum. Shanghai, China: Ministry of Education Information Technology Standards Committee China e-Learning Technology Standardization Committee (CELTSC), pp. 180-194.

Abstract: A desire to customise and personalise learning experiences, combined with the rise of a number of new tool integration technologies has led to a move away from monolithic Virtual Learning Environments (VLEs, also known as Learning Management Systems ‘LMSs’) towards more open and Distributed Learning Environments (DLEs). The various DLE architectures can have very different properties, however, and choosing between them can be difficult.

The Open Group’s ArchiMate standard may help in that regard. It was designed to facilitate communication about architectures between all stakeholders in an organisation. It is a visual language that aims to help conversations about IT systems, business processes, organisational structure and strategy. This paper will present a number of DLE patterns that illustrate the range of possible architectures. Both the potential of these patterns as well as the utility of the ArchiMate language in explicating them will be evaluated.
