4. Starting with Grid
• Allow consumers to obtain computing power on demand.
• Ian Foster and others standardized the protocols.
• Not just computing power
•
•
Data
Software
• Standard organizations to define standards.
( e.g., OGF, OASIS )

•
•
•
• No
•
•
•
•
Vision - Allow consumers to obtain computing power on demand.
Reliability.
Flexibility .
Manage.
Implementations.

6. Cloud Computing
• Definition
A large-scale distributed computing paradigm that is driven by economies of scale, in which a
pool of abstracted, virtualized, dynamically – scalable, managed computing power, storage,
platforms, and services are delivered on demand to external customers over the internet.
• Specialized
•
•
•
Massive Scale
Encapsulated as an abstract entity
Dynamically configured. (driven by economies of scale)

7. Cloud Computing ..
• Main factors to contributing cloud computing
•
•
•
•
Rapid decrease in HW cost and increase in computer power and storage.
Multi – core architecture of modern supercomputers.
Exponentially growing data size in scientific data, internet publishing and archiving.
Adoption of services computing and Web 2.0 applications.

8. Cloud is different
• Evolved and relies on Grid Computing as backbone and infrastructure.
• Utility Computing
•
Business model in which computing resources are packed as metered services.
• Cloud can be utilized internally by a company to the public as utility
computing
• Distributed Computing – enables resource sharing dynamic
•
Infrastructure that spans across multiple virtual organizations where each VO can
consist of either physically distributed institutions or logically related groups.

10. Business Model
• In Cloud
•
Customer will pay on a consumption basis.
•
E.g. : In Windows Azure (2013)
Figure 2: Customized Plan
• Storage Capacity

11. Business Model…
• In Grid
•
Project Oriented
•
E.g. : CPU Hours
XSEDE( Extreme Science and Engineering Discovery Environment ) Former Tera Grid Operates in
CPU Hours.
• There is an industrial Undertaking to build grid economy for Global Grid
infrastructure
•
•
•
•
Support trading
Negotiation
Provisioning
Allocation of resources

14. Resource Management
• Compute Model
•
•
Grid is mostly batch scheduled
Cloud is bit different
•
Allow all users to share resources same time.
Job
Processor : 100
Minutes : 60
Submit Via
GRAM
• Cloud has trouble..?
•
•
Grow in scale
Number of users
From : Cloud Computing and Grid Computing 360-Degree Compared
Local Resource
Manager

15. Resource Management ..
• Data Model
•
In cloud users will have many hardware driven end functionalities that typically run
locally.
•
•
•
Virtualization
Multimedia play back
Grids design to tackle data intensive applications in Grid environment. (Virtual data)
• Data Locality
•
•
Map Reducing systems
Grid uses NFS, GPFS, PVFS and Luster file systems
From : Cloud Computing and Grid Computing 360-Degree Compared

16. Resource Management ..
•
•
•
Virtualization
•
•
Provides necessary abstractions from the fabric
Enables each application encapsulated
Why Cloud tend to adopt Virtualization
•
•
•
Server and Application consolidation
Configurability
Application Availability
