Utility computing

Utility computing , or the Computer Utility , is a service provisioning model in which a service provider makes computing resources and infrastructure management available to the customer as needed, and charges them for specific usage rather than a flat rate. Like other types of on-demand computing (such as grid computing), the utility model seeks to maximize the efficient use of resources and / or minimize associated costs. Utility is the packaging of system resources , such as computing, storage and services, as a metered service. This model has the advantage of a low cost instead, resources are essentially rented.

Ultra-large-scale systems

Ultra-large-scale system (ULSS) is a computer science , software engineering, and systems engineering software. The scale of these systems gives rise to many problems: they will be developed and used by many stakeholders across multiple organizations, often with conflicting purposes and needs; they will be constructed from heterogeneous parts with complex dependencies and emergent properties; they will be continuously evolving; and software, hardware and human failures will be the norm, not the exception. The term ‘ultra-large-scale system’ was introduced by Northrop and others[1] to describe challenges facing the United States Department of Defense . The term has subsequently been used to discuss challenges in many areas, including the computerization of financial markets. [2] The term ‘ultra-wide-scale system’ (ULSS) is sometimes used interchangeably with the term ‘large-scale complex IT system’ (LSCITS). These two terms were described in the US and the latter in the UK.
