Grid Architecture and Relationship to other distributed Technologies

Grid Architecture and Relationship to other distributed TechnologiesPresented by: Waqar AhmadMCS 2nd Presented to: Sir Zeeshan Bangash

GRID ComputingA financial Organization processing wealth management application collaborates with different departments for more computational power and software modeling applications.A Group of Scientists studying the atmospheric O-zone layer will collect huge amounts of experiemental data, each and everyday.Massive online multiplayer game scenarios for a wide community of international gaming participants are occurring that require a large number of gaming computers instead of dedicated game server.A Government organization studying a natural disaster such as a Earthquake may need to immediately collaborate with different departments in order to plan for and best manage the disaster. Load balancing feature integrated into any system in order to avoid processing delays and over commitment of resources.

GRID ARCHITECTURE

World Wide WebWeb is defined as a browser-server, messaging exchange model, and lacks the more complex interaction models required for a realistic virtual organization.A number of open and latest technology is www (TCP, HTTP, XML) that in turn makes the web a suitable candidate for the construction of the virtual organization.

Distributed Computing SystemsDistributed technologies including CORBA, J2EE, and DCOM are well suited for distributed computing applications, However, these do not provide a suitable platform for sharing of resources among the members of the virtual organizations. Some of the notable drawbacks include resource discovery, across virtual participants, collaborative and declarative security, dynamic construction of a virtual organization.

virtual organization (VO) refers to a dynamic set of individuals or institutions defined around a set of resource-sharing rules and conditions virtual organizations share some commonality among them, including common concerns and requirements, but may vary in size, scope, duration, sociology, and structure.7

Application and storage Service ProvidersApplication and Storage service providers (SSP) normally outsource their business and scientific applications and services, as well as very high speed storage solutions, to customers outside their organizations. Customers negotiate with these highly effective service providers on QOS requirements (i.e, Hardware, software, and network combinations.)VPN or dedicated lines by narrowing the domain of security and event interactions.

Peer-to-Peer Computing SystemsSimilar to Grid Computing, P2P computing is a relatively new computing discipline in the realm of distributed computing. Both are focused on resource sharing.

Cluster ComputingClusters are Local to the domain and constructed to source inadequate computing power it is related to the pooling of computational resources to provide more computing power by parelled execution of the workload. Clusters are limited in scope with dedicated functionality and local to the domain and are no suitable for resource sharing among the participants from different domains.The Nodes in a cluster are centeralized controlled and cluster manager is aware of the state of the node.

Resilience can broadly be defined as "the ability [of a system] to cope with change16

Virtualization

Virtualization OverviewWHAT?It is "a technique for hiding the physical characteristics of computing resources from the way in which other systems, applications, or end users interact with those resources. This includes making a single physical resource (such as a server, an operating system, an application, or storage device) appear to function as multiple logical resources; or it can include making multiple physical resources (such as storage devices or servers) appear as a single logical resource."WHY?To save;PowerHardware CostConsolidation (Many into 1)Optimization (Less Physical server is using)
