5. Introduction

6. Introduction

7. What is Grid Computing?
“Allows sharing and coordinated use of diverse
resources in dynamic, distributed “virtual
organizations”

8. What is Grid?
• Distributed: Grid computing is distributed
form of networking that focus on
communications among devices.

9. What is Grid?
• Dynamic: Efficiently utilize wasted cycles,
forming working cycles.

10. The World Grid areas
• Business Areas
• Government Organization
• Financial Organization
• Teachers and educators (E learning)
• Social scientists

12. Why Grid Computing?
• Resource sharing: Global sharing is the essence of grid
computing.
• Secure access:
To ensure secure access, grid developers and users need to
manage three important things:
Access policy - What is shared? Who is allowed to share?
When can sharing occur?
Authentication - How do you identify a user or resource?
Authorization - How do you determine whether a certain
operation is consistent with the rules?

13. Why Grid Computing(cont..)
• Resource use: Efficient, balanced use of computing
resources
• The death of distance: Distance should make no
difference
• Open standards: Standardization also encourages industry
to invest in developing commercial grid services and
infrastructure.

15. Grid Architecture
Fundamental components of a grid's Architecture:
• The Hardware:
A grid depends on underlying hardware like computers and
networks.
• The Middleware:
Middleware is the "glue" that makes grid computing
possible. Middleware is conceptually "in the middle" of
operating systems software (like Windows or Linux) and
applications software (like a weather forecasting
programme).

16. Working of Layers
• Network Layer: The lowest layer is the network, which connects
grid resources.
• Resource Layer: Above the network layer lies the resource layer:
actual grid resources, such as computers, storage systems, electronic
data catalogues, sensors and telescopes that are connected to the
network.
• The middleware layer connect front end with back end.
• Application: The highest layer of the structure is the application
layer, which includes applications in science, engineering, business,
finance and more, as well as portals and development toolkits to
support the applications. This is the layer that grid users "see" and
interact with.

17. Layers..

19. Grid User Roles
(An Administrator’s Perspective)
• Planning
• Installation
• Managing enrolment of donors and users
• Certificate authority
• Resource sharing

20. Grid User Roles
(A User’s Perspective)
• Enrolling and installing grid software
• Logging onto the grid
• Queries and submitting jobs
• Data configuration
• Monitoring progress and recovery

21. Some Grid Applications
Distributed supercomputing
High-throughput computing
On-demand computing
Collaborative computing

23. Advantages
• Can solve larger, more complex problems in a
shorter time
• Easier to collaborate with other organizations
• Resource Balancing.
• Flexible, Secure, Coordinated resource sharing.
• Give worldwide access to a network of distributed
resources.

24. Disadvantages
• Need for interoperability when different
groups want to share resources.
• But how do I develop robust, secure, long
lived, well performing applications for
dynamic, heterogeneous Grids?
