Abstract

Today, business organizations seem to be involved in the processes of sustainable development. Therefore, not only economic indicators of performance are considered but also the environmental responsibility is equally important. The environmental responsibility covers social responsibility and natural environment responsibility. The latter demands taking into account promotion of sustainable use of renewable natural resources, reducing the emissions and wastages, decrease of energy consumption. The first part of the paper includes presentation of benefits resulting from IT (Information Technology) resources virtualization, grid computing and cloud computing development. The second part contains a model of IT governance for sustainability.

Background - Information Technology Infrastructure Virtualization

Virtualization is a broad term encompassing a set of several deployment and management features and could be defined as a technique used to abstract the physical characteristics of the resources of a system from other systems, applications or users interacting with those resources (IBM, 2008). The virtualization can make a single physical resource appear to be multiple logical resources, or multiple physical resources appear to be a single logical resource.

Virtualization is viewed as:

  • File virtualization: multiple files aggregated into a large file, presents integrated file interface,

  • Software virtualization: enabling users to use more-efficient, high-performance hardware to support hundreds of applications and several operating systems in a single system. Applications are used in data path, or in “plug-and-play” way from host view,

  • Desktop virtualization: providing the access from anywhere for convenience and to ensure business continuity and disaster recovery,

  • Workstation virtualization: enabling the centralized control of data and the efficient administration of them among multiple users in different locations,

  • Storage virtualization: enabling users to centralize data storage to protect data, improve security and disaster recovery, and accelerate data backups, while desktop virtualization enables moving of data, applications, and processing away from desktop PCs onto secure, cost-efficient virtualized network resources, replacing PCs with virtualized thin-client computers (Moore, 2006).
