Evolution of Computing
Mainframe Computer
Personal Computers
• Client-Server
• Web Era
• And the biggest thing since the web….
Cloud computing is a buzzword..."The concept, quite simply, is that vast computing resources will
reside somewhere out there in the ether (rather than in your computer room) and we'll connect to them and use them as
needed.“- Jonathan Weber (The Times Online)
How much data?
• Wayback Machine has 2 PB + 20 TB/month • Google processes 20 PB a day • “all words ever spoken by human beings” ~ 5 EB• NOAA has ~1.3 PB climate data • CERN’s LHC will generate 15 PB a year
640K ought to be enough for anybody.
Grid Computing• Grids are collections of computer resources, owned by multiple
organizations, that are coordinated to solve a common problem.
• Its distinctive feature is that it can link machines owned by different organizations.

Main Benefit Grids are on premise and owned by an organisation
Clouds are normally provided by vendors on as needs by organisations
Resource Distribution/allocation
Negotiate and manage resource sharing ; schedulers
Simple user-provider model , pay per use
Domains Multiple Domains Single Domain
Character/History Non-Commercial , publicly funded
Commercial
Method for Computing Task
Single Task is split into multiple task and distributed to multiple computing machine and then again reassemble after completion of task
Enable users to use difference service without the need for investment in architecture , also apart from computing other services can also done like-web hosting etc.
Grid vs Cloud
Properties of Cloud Computing
• Transparency• Scalability• Intelligent Monitoring• Security

Cloud Computing
-Sonali Kalani
Why Cloud Computing?
• Lower IT Costs• “Pay for What You Use” Structure• Multi-tenancy• Mobility Incarnate• Simplified Updating• Fast, Easy Implementation• Accessible Support Staff• Decreased Down-Time
Architecture

Deployment Models
• Private• Public• Community• Hybrid
Private Cloud
• On-demand infrastructure owned by a single customer (organisation) who controls the running of applications
• Organization owns physical resources and provides access to users• Good option for companies dealing with data protection and
service-level issues• Examples of Private Cloud:
– Eucalyptus– Ubuntu Enterprise Cloud - UEC (powered by Eucalyptus)– Amazon VPC (Virtual Private Cloud)– VMware Cloud Infrastructure Suite – Microsoft ECI data center
NIST Definition of Cloud Computing
Community Cloud
• Cloud infrastructure is shared by several organizations
• May be managed by the organizations or a third party
• Cost is spread over more users compared to private cloud
• Examples of Community Cloud:– Google Apps for Government– Microsoft Government Community Cloud
NIST Definition of Cloud Computing
Public Cloud
• Infrastructure made available to general public• Owned by organization selling cloud services• Services are free or “pay per use”• Almost a synonym for ‘Cloud Computing’• Examples of Public Cloud:
– Google App Engine– Microsoft Windows Azure– IBM Smart Cloud– Amazon EC2
NIST Definition of Cloud Computing
Hybrid Cloud
• Composition of two or more clouds (private, community, or public)
• Bound together by standardized or proprietary technology that enables data and application portability
• Examples of Hybrid Cloud:– Windows Azure (capable of Hybrid Cloud)– VMware vCloud (Hybrid Cloud Services)
NIST Definition of Cloud Computing
Service Models
• Infrastructure as a service (IaaS)• Platform as a service (PaaS)• Software as a service (SaaS)
Infrastructure as a Service (IaaS)
• Most basic cloud service model• Providers offers computers, as physical or virtual
machines, block storage, firewalls, load balancers, like switches and routers, and networks
• Users install OS and application software• User responsible for patching and maintaining the
operating systems and application software• Example:
– Amazon Web Services– Joyent
Source: Sun Introduction to Cloud Computing Architecture (White paper)
Platform as a Service (PaaS)
• Offers operating system, programming language execution environment, database and web server
• Provides for every phase of software development and testing• No need to buy and manage the underlying hardware and
software layers by the customer• Can be specialized around a particular area like content
management• Example:
– Google App Engine
Source: Sun Introduction to Cloud Computing Architecture (White paper)
Software as a Service (SaaS)
• Delivery model in which software and associated data are centrally hosted on the cloud
• Cloud infrastructure and platform on which the application is running is managed by a service provider
• Based on multi-tenancy architecture• Cloud providers install and operate application software in
the cloud and cloud users access the software from cloud clients
• Example:– Google mail– SalesForce.com

Eucalyptus
• Opensource developed by University of California, Santa Barbara.
• Implements IaaS• Compatible with AWS-EC2
Features
Eucalyptus will provide compatibility to the most popular Amazon Web Services including:• Amazon Elastic Compute Cloud (EC2)• Amazon Elastic Block Storage (EBS)• Amazon Machine Image (AMI)• Amazon Simple Storage Service (S3)• Amazon Identity and Access Management (IAM)
http://www.eucalyptus.com/
Benefits to Customers
• Access the ecosystem of tools designed for AWS, including monitoring, cloud service management, and image management
• Move deploy and manage AWS-compatible your applications between on-premise Eucalyptus environments and the AWS Cloud
• Take advantage of a common web services platform between AWS and Eucalyptus Web Services supporting EC2, EBS, S3, and IAM
• Standardize application and usage policies using IAM for both Amazon and Eucalyptus
• Satisfy regulatory and compliance requirements by using AWS and on-premise Eucalyptus to keep private data in your own data center.

Recent Trends and Conclusion
-Subhashis Das
Recent Trends
• Microsoft private cloud is a cloud service which dedicated to your organization whether they exit on-premises or off-premises.
• Benefits ---Self-service, scalability and elasticity with additional control and customization available from dedicated resource.
• It is a cloud storage and cloud computing service from apple Inc. • It allows user to store data such as music, document, pic on remote computer
sever for download to multiple device such as mobile, pc, laptop, ipad etc. http://www.apple.com/icloud/features/documents.html
Research Trends
• A number of universities, vendors and government organizations are investing in research around the topic of cloud computing.
• In July 2008,HP,Intel Corporation and Yahoo! announced the creation of a global, multi-data center, open source test bed, called Open Cirrus designed to encourage research into all aspects of cloud computing, service and data center management.
Open Cirrus is an open cloud-computing research testbed designed to support research into the design, provisioning, and management of services at a global, multi-datacenter scale.
• The open nature of the testbed is designed to encourage research into all aspects of service and datacenter management.
Some library products in the cloud
The cloud enables more than just applications… • Ebooks as cloud-based products
– Overdrive• Allows patron downloads onto mobile devices
– 3M• Also allows patron downloads onto mobile devices
-Google Books
• Allows user downloads onto Android-powered devices, • -My Library Application – HathiTrust
• Allows user downloads of public domain ebooks.
New vendor-based library services• StackMap
– Allows patrons to view locations in the library on their mobile devices
• Third Iron– Browzine’s iPad app allows users to browse current journal articles and download, save, and share them
St. Paul Library debuts 3M's Cloud Library for e-book lending
Cloud Computing In India
• NASSCOM research report entitled “Deconstructing the Cloud: The New Growth Frontier for Indian IT-BPO Sector”.
• The study reveals that, cloud computing is expected to have a significant impact on the services industry, in terms of services offered, delivery mechanisms and business models. The Indian market for cloud computing is expected to grow by $16 billion in 2020
• In INDIAN Libraries, implementation of cloud computing is still not done .But it can be proven beneficial due to its cost effectiveness and effective service and thus can help to give new outlook to Indian Libraries
Cloud Computing is the Wave of the Future
