The exact technical name for Hyper-V in Windows 8 is Client Hyper-V. [ Also on InfoWorld: Review: VMware Workstation 9 vs. People may disagree about Windows 8's new surface, pun intended, but there's little arguing that many great things have happened under the hood.

Cloud computingCloud computing metaphor: For a user, the network elements representing the provider-rendered services are invisible, as if obscured by a cloud. Cloud computing is a computing term or metaphor that evolved in the late 1990s, based on utility and consumption of computer resources. Cloud computing involves application systems which are executed within the cloud and operated through internet enabled devices. Purely cloud computing does not rely on the use of cloud storage as it will be removed upon users download action. Overview Cloud computing relies on sharing of resources to achieve coherence and economies of scale, similar to a utility (like the electricity grid) over a network. At the foundation of cloud computing is the broader concept of converged infrastructure and shared services. Cloud computing, or in simpler shorthand just "the cloud", also focuses on maximizing the effectiveness of the shared resources. History of cloud computing Origin of the term
Amazon Web ServicesAmazon Web Services (AWS) is a collection of remote computing services, also called web services, that make up a cloud computing platform offered by Amazon.com. These services are based out of 11 geographical regions across the world. The most central and well-known of these services are Amazon EC2 and Amazon S3. These products are marketed as a service to provide large computing capacity more quickly and cheaper than a client company building an actual physical server farm. Architecture Map showing the approximate geographical regions used by Amazon Web Services. AWS is located in 11 geographical "regions": US East (Northern Virginia), where the majority of AWS servers are based, US West (northern California), US West (Oregon), Brazil (São Paulo), Europe (Ireland and Germany), Southeast Asia (Singapore), East Asia (Tokyo and Beijing) and Australia (Sydney). Each Region has multiple "Availability Zones", which are distinct data centers providing AWS services. History
OpenStackOpenStack is a free and open-source cloud computing software platform. Users primarily deploy it as an infrastructure as a service (IaaS) solution. The technology consists of a series of interrelated projects that control pools of processing, storage, and networking resources throughout a data center—which users manage through a web-based dashboard, command-line tools, or a RESTful API. OpenStack.org released it under the terms of the Apache License. OpenStack began in 2010 as a joint project of Rackspace Hosting and NASA. The OpenStack community collaborates around a six-month, time-based release cycle with frequent development milestones. During the planning phase of each release, the community gathers for the OpenStack Design Summit to facilitate developer working-sessions and to assemble plans. History In 2012, Red Hat announced a preview of their OpenStack distribution, beginning with the "Essex" release. Components Compute (Nova) Database (Trove)
Enterprise integrationConcept of Enterprise Integration. Enterprise integration is a technical field of Enterprise Architecture, which focused on the study of topics such as system interconnection, electronic data interchange, product data exchange and distributed computing environments. It is a concept in Enterprise engineering to provide the right information at the right place and at the right time and thereby enable communication between people, machines and computers and their efficient co-operation and co-ordination. Overview Requirements and principles deal with determining the business drivers and guiding principles that help in the development of the enterprise architecture. Each functional and non-functional requirement should be traceable to one or more business drivers. Enterprise Integration is focused on optimizing operations in a world which could be considered full of continuous and largely unpredictable change. History Enterprise integration topics See also
