Indeed, grid computing is often (but not always) associated with the delivery of cloud computing systems as exemplified by the AppLogic system from 3tera. A grid computing system can be as simple as a collection of similar computers running on the same operating system or as complex as inter-networked systems comprised of every computer platform you can think of. Other systems employ measures to reduce the amount of trust “client” nodes must place in the central system such as placing applications in virtual machines. For the segmentation of the grid computing market, two perspectives need to be considered: the provider side and the user side: The overall grid market comprises several specific markets.

A grid is a type of parallel and distributed system that enables the sharing, selection, and aggregation of resources distributed across ‘multiple’ administrative domains based on their (resources) availability, capacity, performance, cost and users' quality-of-service requirements”. Grid computers also tend to be more heterogeneous and geographically dispersed (thus not physically coupled) than cluster computers. Major players in the utility computing market are Sun Microsystems, IBM, and HP. The utility computing market provides computing resources for SaaS providers. M. K. Singh The size of a grid may vary from small—confined to a network of computer workstations within a corporation, for example—to large, public collaborations across many companies and networks. According to the project fact sheet, their mission is “to establish effective routes to foster the adoption of grid computing across the EU and to stimulate research into innovative business models using Grid technologies”. The designers of the system must thus introduce measures to prevent malfunctions or malicious participants from producing false, misleading, or erroneous results, and from using the system as an attack vector. In many cases, the participating nodes must trust the central system not to abuse the access that is being granted, by interfering with the operation of other programs, mangling stored information, transmitting private data, or creating new security holes. Software as a service (SaaS) is “software that is owned, delivered and managed remotely by one or more providers.” (Gartner 2007) Additionally, SaaS applications are based on a single set of common code and data definitions. [26] The relevant software and documentation is also publicly accessible. Grid middleware is a specific software product, which enables the sharing of heterogeneous resources, and Virtual Organizations. BOINC is a common one for various academic projects seeking public volunteers; more are listed at the end of the article. The tenets of cloud computing that include distributed systems, complemented with grid computing and parallel programming strategies as well as virtualization technologies allowing for the development of multilayer environments (Armbrust et al., 2010; Liu et al., 2014) present unique opportunities to precision medicine as they permit robust and secure distributed analysis (Marx, 2013). While the Globus Toolkit remains the de facto standard for building grid solutions, a number of other tools have been built that answer some subset of services needed to create an enterprise or global grid.
