Information Explosion
– Due to the popularity of Internet digital content is growing
exponentially and needs to be accessed quickly by all
– Today’s science is based on worldwide collaborations by
sharing computations, data, expensive equipments,
information/knowledge/wisdom across the Internet
– Researchers need more accurate & precise solutions to
their problems (from 1D to 3D) in shortest possible time

Mega Science Projects
•The LHC and Astro-
particle physics
experiments offer new
glimpses beyond the
current frontiers.
� LHC experiments will produce 10-15 million Gigabytes of data each year (about 20 million CDs!)
� LHC data analysis requires a computing power equivalent to ~ 100,000 of today's fastest PC processors.
� Requires many cooperating computer centres, CERN providing only ~20% of the CPU power
And the computing infrastructure to support such physics
research needs to look beyond the cutting edge.

Trend: Network Infrastructure
� Grid has demanded deployment of an advanced network infrastructure for
Research & Education to be effective
� Light (lambda network facility) is the response to the need for high-quality
research and education. It will
� help create a viable economy-of-scale model for the region to
reduce networking costs per country,
� serve as a testbed for development of new services, and allow the
R&E community to participate in international networking
activities
� support the growth of National Research & Education Networks
(NRENs), accelerate research, fuel national and regional economic
growth, and aid their integration with the rest of world.
� Many countries today have Lambda Network Facility – an e-infrastructure

New Challenges in ICT
� Today’s ICT infrastructure is much more complex
� Distributed Computing (Clusters & Grids: PetaFlop Computing)
� Internet & Connectivity (OFC: e-infrastructures: Terabit Networking)
� Virtualisation (Distributed File System: Exabyte Storage)
� Heterogeneity and multidisciplinary information
� Software (Open Source Software and Open Standards)
� ICT isn’t glamorous any more – it just needs to keep working – reliability is everything
� Reliability and robustness are expensive and typically mean less flexibility
� Cost effectiveness and flexibility usually mean less reliability
� Need for Improved Efficiency, Business Continuity & Increased Agility
� Users no longer want to manage ICT infrastructures on 24X7 basis but would like to out source

Green Computing Initiative
– Almost half of recurring expenses on data centres come from
power bills (24/7 operation; example EKA)
– Measures like consolidation and virtualization are used to achieve
optimal utilization of IT infrastructure (Grids)
– Green Computing Initiatives and energy efficient technologies
(reduce emissions& increase cooling efficiency)
– Data centres are being redesigned to go green business processes
(Use of energy efficient technology like blade servers, thin client, LCD’s
etc; Global warming culprits)
– Only 20% computing resources come from Tier o centre at CERN
and rest come from collaborators (methods to improve operational
efficiencies)

Cloud Computing: Computing as a Service
Provision of virtualized resources on a commercial Cloud for example by
Amazon, IBM, Google, Yahoo, Microsoft, so that user need not own the
resources or invest on it but can use it transparently & dynamically as per
his demand paying only for the usage
What is Cloud Computing?
A style of computing where
massively scalable IT-enabled
capabilities are provided "as a
service" over the Internet to
multiple users
Grid is a enabling technology for
Cloud computing

What is Cloud Computing?
4+ billion phones by 2010 [Source: Nokia]
Web 2.0-enabled PCs, TVs, etc.
Businesses, from startups to enterprises
An emerging computing paradigm where data and services reside in massively
scalable data centers that can be ubiquitously accessed from any connected
devices over the Internet. The cloud – a service oriented business/
software/hardware platform on the Internet -- rather than from a specific
identifiable device -- aims to deliver supercomputing power over the Internet --
any subscription-based or pay-per-use service that in real time, extends IT's
existing capabilities over the Internet

Benefits of Cloud Computing
• Cloud computing providing unlimited infrastructure to store and
execute customer data and program. As customers you do not
need to own the infrastructure, they are merely accessing or
renting, they can forego capital expenditure and consume
resources as a service, paying instead for what they use.
Benefits of Cloud Computing :
• Minimized Capital expenditure
• Location and Device independence
• Utilization and efficiency improvement
• Very high Scalability (expand on-the-fly as needed)
• High Computing power

National Knowledge Network: Objective
� The objective of the National Knowledge Network is to
bring together all the stakeholders in Science, Technology,
Higher Education, Research and Development, GRID
Computing, e-governance with speeds scalable eventually
up to the order of 10s of gigabits per second coupled with
extremely low latencies.
� NKN will interconnect all the research, higher education

Concerns about Cloud Computing
– Performance, reliability, and SLAs,
– Control of data, and service parameters,
– Application features and choices,
– Interaction between Cloud providers,
– No standard APIs – mix of SOAP and REST!
– Privacy, security, compliance, trust…

Summary
• NREN have become major platform for e_science users
• Cloud Computing is seen as the next generation
architecture of IT Enterprise – a flexible & affordable IT
infrastructure
There is no need for the user to own the IT infrastructure, it
can be merely accessed or rented, by paying for the actual use
thus saving huge cost & headaches of IT management
• We are learning creation, operation and negotiations of
Virtual organizations (VO) in NKN
• Issues in security or security problems, quality and
reliability in NKN have to be handled with care

Benefits of NKN
• National Research & Education Network(NREN): e-
infrastructure
- Ultra High speed (OFC), low latency network with scalability in
terms of reach & capacity
• Cost advantage due to consolidation and sharing - virtualization
• Central depository of software services & data bases for
multidisciplinary applications - effective usage
• Foundation for seamless & secure collaboration over network – uniform interfaces
