Grid Computing Model

Grid : Run a program X, using resources at site Y,using VO communication policy P, providingaccess to data at Z, according to policy Q.

Problem 1: X has to be able to work inheterogeneous and geographically dispersedenvironment.

Problem 2 (Systems problem): How to coordinate

the use of resources at sites Y and Z under thevarious restrictions on their usage as defined bypolicies P and Q.

Grid

Grid Computing enables VOs to share

geographically distributed resources as they

purchase common goals, assuming the

absence of central location/control,

omniscience, and existing trust relationship

Grid

To achieve these Goals, Grid Environmentmust be:

Large Scale

Dynamic Scalable

Inter-operable

Extensible Secure

Heterogeneous

NGN

Latest evolution of global telecommunicationsnetworks (ETSI and ITU-T), the Nextgeneration Networks (NGNs), is designed to

support converged fixed and wirelessnetworks carrying both voice and data traffic.

Further, it incorporates a richer set of featuresto provide more services to customers, andhence increased revenue opportunities for then/w providers.


11/26

Why Telcos are interested in IT?

Attributes provided:

Enterprise sales capability

Lifecycle service and support

Reliable operations at scale

SLAs

Full enterprise solutions portfolio

Integrated hosting and network services

Vendor independence

Global Footprint

Financial stability and market commitment


12/26

Convergence of NGN, Grid and Cloud

Telco operators are more and more driving SOA

implementations in order to:

Decouple applications via middleware from IT

server/storage/network resources Flexibly compose new services using standards-based

technologies and protocols

Reuse architectural components to lower costs, time-

to-revenue

Rapidly manage configuration, change management

and services assurance with automation.

Implications of combining

Using NGN to deliver Grid/Cloud Services

Grid Services requirements are (OGSA):

Discovery, Metering and accounting, Monitoring,

Brokering, Authentication and authorization,

Advance reservation, Scheduling, Transport

management, Data sharing and management,

Policy

Using Grid/Cloud services to support NGN

Grid/Cloud SOA, NGN functional architecture


19/26

Standards for Grid and NGN

OGF: SOA based Web services Resource Framework (WSRF)

Distributed Management Task Force: Common InformationModel and enterprise system modeling, monitoring andcontrol

European Telecommunications Standards Institute: ThrTISPAN (Telecommunications & Internet converged Services& Protocols for Advanced Networking) NGN architectureand IMS (IP Multimedia Subsystem)

Internet Engg. Task Force: X.509, PKI, TLS/SSL

Organization for Advancement of Structured Information(OASIS): XML and Web services,

W3C: Original XML/web based RPC, SOAP etc

Storage Network Industry Association


20/26

Interoperability

Gateway/adapter approach: short term

solution, specific

Standardization: OGF group GIN (Grid

Interoperability Now)


21/26

Standardization Gaps

Gaps and overlaps are likely to be

encountered in several different situations:

Applications composing of services making use of

various networks (NGN?) Relationship between grid and underlying n/w

Diversity allowed in individual standards

Use of dynamic working Transition to new version of specs

Lack of implementations


22/26

Classification of Gaps

Architecture

Security

SLA and QoS

ChargingService Discovery

High-level issues contributing to gaps- come from

human processes, composition of services orarchitectural layers and the life-cycle ofcomposite systems

Grid-Cloud: IT Platform for Service

Science

Service Science is proposed as an integrative

discipline of engineering, technological, and

social sciences (including business and law)

with the purpose of creating new technologyand market for providing high value service.
