A disadvantage of a two-tier design is the inability to represent application logic in separate components, which inhibits software reuse. The OGSI is the standard that will provide the interoperability between grids designed using OGSA. This task could be carried out by a broker function. These are typically "umbrella" projects that have a number of sub-projects underneath them, with multiple research areas. About This Quiz & Worksheet. The grid computing model is a special kind of distributed computing model. The Grid Security Infrastructure (GSI) component of the Globus Toolkit provides robust security mechanisms. A planner wishing to use grid principles and wishing to deploy a grid mechanism in his/her Fortune 500 company, will have to deploy and support a number of these components, perhaps all, depending on the application and situation. Grid computing is distinguished from conventional high-performance computing systems such as cluster computing in that grid computers have each node set to perform a different task/application. ��ࡱ� > �� ; = ���� 8 9 : ������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������ 9 �R� H bjbj���� Ȫ �� �� D �� �� �� l � � � � � � � � � � � � � � � � � $ C He has over 10 years of experience at the ITSO, where he has been writing IBM redbooks and creating and teaching workshops around the world on a variety of topics. across a distributed set of resources instead of one central resource. Rather than each house or neighborhood having to obtain and maintain its own generator of electricity, the power grid infrastructure provides a virtual generator. It … The three primary types of grids are summarized below. If you do not receive an email within 10 minutes, your email address may not be registered, bjacob@us.ibm.com)ITSO Redbooks Project Leader, IBMJune 2003 Grid computing is gaining a lot of attention within the IT industry. As mentioned, Globus Toolkit V3 will be the reference implementation for OGSA. Cloud Computing architecture comprises of many cloud components, which are loosely coupled. For instance, Globus provides a rapid development kit known as CoG (Commodity Grid) which supports technologies such as Java, Python, Web services, CORBA, and so on. Figure 5. (See HYPERLINK "http://www-106.ibm.com/developerworks/grid/library/gr-overview/" \l "resources" Resources.) For instance, you might need services such as life-cycle management, accounting, and charge back systems. The Base One Grid Computing Architecture: Introduction. High-level overview of Grid computingThe most common description of Grid computing includes an analogy to a power grid. In this article, we give you an overview of the key components that make up a Grid environment, and we present most of our information and concepts within the context of the Globus Toolkit. C However, as you consider developing applications that may run in a grid environment, remember that the type of grid environment that you will be using will affect many of your decisions. Scheduler INCLUDEPICTURE "http://www-106.ibm.com/developerworks/grid/library/gr-overview/grid4.jpg" \* MERGEFORMATINET Data managementIf any data -- including application modules -- must be moved or made accessible to the nodes where an application's jobs will execute, then there needs to be a secure and reliable method for moving files and data to various nodes within the grid. Globus Toolkit V3 (available now in beta) will be the reference implementation for OGSA. O ) � � d ) ) ) C Software- programs used to control the resources, or perform needed processing. 2. Types of gridsGrid computing can be used in a variety of ways to address various kinds of application requirements. It also provides a single sign-on mechanism, so that once a user is authenticated, a proxy certificate is created and used when performing actions within the grid. Portal/user interfaceJust as a consumer sees the power grid as a receptacle in the wall, a grid user should not see all of the complexities of the computing grid. A higher level scheduler (sometimes called a meta scheduler) might be used to schedule work to be done on a cluster, while the cluster's scheduler would handle the actual scheduling of work on the cluster's individual nodes. The Grid means the infrastructure for the Advanced Web, for computing, collaboration and communication. Figure 3. The goal is to create the illusion of a simple yet large and powerful self managing virtual computer out of a large collection of connected heterogeneous systems sharing various combinations of … Grid architecture: Protocol, service definition for interoperability & resource sharing. Both grid and P2P systems can serve as platforms for web services. Owners of the desktop machines are usually given control over when their resources are available to participate in the grid. Working off-campus? substations are used to transform voltage at several times in many locations, that providing safe and reliable delivery of energy. The facilities provided by Globus can be used to build grids and grid-enabled applications today. Smart Substations: substations are included monitoring and control non-critical and critical operational data such as power status, power factor performance, breaker, security, transformer status, etc. ) + + + + + + $ b" �$ � O � C Moreover, we will learn important components of Cloud Computing architecture and some cloud-based delivery like Saas, PaaS, IaaS. Figure 6. The Open Grid Services Interface (OGSI) specification is a companion standard that defines the interfaces and protocols that will be used between the various services in a grid environment. In this type of grid, most of the machines are high-performance servers. 4.

A data grid would allow them to share their data, manage the data, and manage security issues such as who has access to what data. Processors- the brains of the computer, the part that performs any needed calculations or processing. For instance, inter-process communication and accounting/chargeback services are two common facilities that are often required. It is also not possible to distribute application logic to a separate computer. 2. To reach this vision, there must be standards for Grid computing that will allow a secure and robust infrastructure to be built. " Many such environments have been built.
