GIIS (Grid Index Information Service ) - permalink - collapse

All > Technology > Parallel Computing > Grid Computing

Grid Index Information Service is the database that contains indexes of resource information registered by the GRIS and other GIISs. It can be seen as a grid-wide information server. GIIS has a hierarchical mechanism, like DNS, and each GIIS has its own name. This means client users can specify the name of a GIIS node to search for information.

GME (Grid Management Entity) - permalink - collapse

All > Technology > Parallel Computing > Grid Computing

The grid management entity (GME) manages all of the grid components within an enterprise grid, including -
- Their relationships with one another, for example mapping operating systems and applications onto servers and networks
- Their life cycle, for example discovering, configuring, starting and stopping components.
The GME may be realized -
- Through people and process
- Through technology
- A combination of the above.
The GME provides the context for understanding the key problems associated with managing enterprise grids and grid components today. See also: Enterprise Grid, Grid Component

Grid Component - permalink - collapse

All > Technology > Parallel Computing > Grid Computing

The grid component is a super class of object that represents every managed entity, whether physical or logical, within an enterprise grid. Grid components are recursive, in that they may be aggregated to form other grid components, or decomposed into their constituent grid components.

Examples of grid components include, but are not necessarily limited to - Traditional resources such as servers, switches, disks, arrays and routers. These are considered to be elemental grid components.
- Less obvious resources such as a software distribution or perhaps data.
- Services, such as CRM, ERP etc.
- Everything in between.
Thus, for example, an ERP service may be decomposed into database, application server and web tiers. These may in turn be decomposed into instances that are bound to operating system instances and servers. Each of these is considered to be a grid component. Whether a grid component is viewed as a service or as a resource and depends on context. Each grid component has a life cycle which has to be managed and may encompass a number of phases, including:
- Add
- Configure
- Start
- Stop
- Unconfigure
- Remove

Grid Computing - permalink - collapse

All > Technology > Parallel Computing > Grid Computing

A computing architecture that provides computing resources using many computers acting as one virtual computing resource. On the client side, grid computing provides a pool of shared resources, allowing complete transparency as to where and how a task is performed. On the server side, grid computing enables enterprises to provision resources to respond to client requests. Grid computing environments are often typified by:
- Distributed, shared pools of resources to achieve greater performance, scaling, resilience, and utilization
- Flexibility, as components are regularly re-provisioned in line with business goals
- Application or service architectures, such as Service Oriented Architectures (SOAs), which are disaggregated/distributed
- Consolidation into a smaller number of larger resource pools for easier provisioning and greater utilization
- Automation of day-to-day manual maintenance - software installation, patching, upgrading, workload balancing, etc.
- Standardization of components and/or their interfaces, configurations, processes, and applications (see "Virtualization").

A type of distributed computing in which a wide-ranging network connects multiple computers whose resources can then be shared by all end-users; includes what is often called "peer-to-peer" computing.
IBM - Cite This Source - This Definition
The use of pools of resources onto which applications or services may be dynamically provisioned and re-provisioned to meet the goals of one or more enterprises, whilst improving both efficiency and agility. Grid computing environments may be typified by
- The use network distributed, shared pools of discrete resources to achieve greater performance, scaling, resilience and utilization
- Flexibility or mutability, as components are regularly repurposed or re-provisioned in line with the business goals for the services that run on them
- A focus on services, rather than on components, as grids turn networks into arbitrarily rich/complex fabrics of resources.
- Application or service architectures which are disaggregated or distributed in nature, for example Service Oriented Architectures (SOAs) and which leverage the properties of the fabric of resources.
- The consolidation of computing components into [typically] a smaller number of larger resource pools to enable easier provisioning and greater resource utilization.
- The standardization of components and/or their interfaces, configurations, processes and applications. Virtualization is an example of this.
