Cloud computing[ 1 ] is the on-demand availability of computer system resources, especially data storage (cloud storage) and computing power, without direct active management by the user. [ 2 ] Large clouds often have functions distributed over multiple locations, each of which is a data center.
Reference model. A reference model —in systems, enterprise, and software engineering —is an abstract framework or domain-specific ontology consisting of an interlinked set of clearly defined concepts produced by an expert or body of experts to encourage clear communication. A reference model can represent the component parts of any ...
PERA Reference model: Decision-making and control hierarchy, 1992. Purdue Enterprise Reference Architecture (PERA), or the Purdue model, is a 1990s reference model for enterprise architecture, developed by Theodore J. Williams and members of the Industry-Purdue University Consortium for Computer Integrated Manufacturing.
Cloud computing architectures consist of front-end platforms called clients or cloud clients. These clients are servers, fat (or thick) clients, thin clients, zero clients, tablets and mobile devices that users directly interact with. These client platforms interact with the cloud data storage via an application (middle ware), via a web browser ...
A software reference architecture is a software architecture [ 1 ] where the structures and respective elements and relations provide templates for concrete architectures in a particular domain or in a family of software systems. An implementation of a reference architecture is called a framework or an application platform.
Software as a service. Software as a service (SaaS / sæs / [1]) is a cloud computing service model where the provider offers use of application software to a client and manages all needed physical and software resources. [2] Unlike other software delivery models, it separates "the possession and ownership of software from its use". [3]
e. The Open Systems Interconnection (OSI) model is a reference model from the International Organization for Standardization (ISO) that "provides a common basis for the coordination of standards development for the purpose of systems interconnection." [ 2 ] In the OSI reference model, the communications between systems are split into seven ...
Platform as a service (PaaS) or application platform as a service (aPaaS) or platform-based service is a cloud computing service model where users provision, instantiate, run and manage a modular bundle of a computing platform and applications, without the complexity of building and maintaining the infrastructure associated with developing and launching application(s), and to allow developers ...
