Evolution of ComputingMainframe ComputerPersonal 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 well 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. Source: http://www.csa.com/discoveryguides/grid/reviewf.php
Grid vs CloudMain Benefit Grids are on premise and Clouds are normally provided owned by an organisation by vendors on as needs by organisationsResource Negotiate and manage Simple user-provider model ,Distribution/allocation resource sharing ; schedulers pay per useDomains Multiple Domains Single DomainCharacter/History Non-Commercial , publicly Commercial fundedMethod for Computing Single Task is split into multiple Enable users to use differenceTask task and distributed to service without the need for multiple computing machine investment in architecture , and then again reassemble also apart from computing after completion of task other services can also done like-web hosting etc.
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 Source: Sun Introduction to Cloud Computing Architecture (White paper)
6 Attributes of Cloud Services Source: http://www.gartner.com
Standardization-• Open Grid Forum• Cloud Computing Interoperability Forum• Distributed Management Task Force• Open Cloud Consortium• Cloud Security Alliance• European Telecommunication Standard Group• Organization for the Advancement of Structured Information Standards• Object Management Group
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.

Service providers of Cloud computing for librariesPolaris Library Systems• Library Automation System• It also provides standard acquisition and processing system.• The systems uses number of well know standards like MARC 21 for bibliographic data, XML, Z39.50 for information retrieval, Unicode etc.
Dura Cloud• Digital library services• Its concern of the Duraspace which is a collaboration of the Dspace digital library software and Fedora Commons• It is available for all type of libraries and also for consortia• It offers complete solution for digital library with standard software and hardware solution• It also provides open source code and the code needs to be installed on your machine
• 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 cloudThe 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 3Ms 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 Convenience Software as a Subscription Reduced Software Maintenance Increased Reliability Security and backup Increased Scalability
Cloud Computing is the Wave of the Future Cost Reduction Storage Environmentally Friendly/ Green Credentials Matches Current Computing Trends Portability/Accessibility Efficient Use of Computer Resources Version less Software and/or Universal access
Conclusion• So Cloud computing is the one point solution to get all updated software, Apps with low cost and less maintain and without about data, document scattering.• Now is the time to look to the cloud for mobile solution in libraries
