  1. 1. Cloud Computing:An Economic Solution for LibrariesSeries Of Student Seminar - 2012Amit Kumar ShawMS in Library & Information Science,StudentDocumentation Research and Training CentreIndian Statistical Institute, Bangalore
  2. 2. AgendaCloud Computing Introduction of Cloud Computing Characteristics of Cloud Computing Models and Types of services of Cloud Computing Architecture of Cloud Computing Why Cloud Computing ? Pros and Cons of Cloud Computing Real World Examples
  3. 3. PollDo you use the cloud? Yes, all the time Yes, but I still don’t trust it formy sensitive info No, I don’t trust it No, I don’t have a goodenough connection to rely on it Not Sure
  4. 4. Six Computing Paradigmssource:
  5. 5. What is Cloud Computing?
  6. 6. Definition - NIST Cloud computing is a model for enabling everywhere,convenient, on-demand network. Configurable computing resources (e.g., networks, servers,storage, services, and applications) Rapidly provisioned and released with minimal managementeffort.
  7. 7. Characteristics On-demand self-service: The ability for an end user to sign upand receive services without the long delays that havecharacterized traditional IT. Broad network access: Ability to access the service viastandard platforms (desktop, laptop, mobile etc). Resource : Resources are access across multiple customers. Rapid elasticity: Capability can scale to cope with demandpeaks Measured service: Billing is metered and delivered as a utilityservice.
  8. 8. On the basis of UsagePublic Cloud: Service providers offer their resources as services to generalpublic. No initial capital investment on infrastructure and shifting risk Lacks in control over data, network and security settings.
  9. 9. Private Cloud: Deployed inside the firewall and managed by the userorganization User organization owns the software and hardware running inthe cloud Resources typically not shared outside the organizationand full control is retained by the organization
  10. 10. Hybrid Cloud: It consists of both internal and externalproviders which means both privateand public clouds. It may be organizations or universities,but they share common concerns suchas their mission, policies, onlineresources, security, regulatorycompliance needs, and so on.
  11. 11. Types of Service Infrastructure as a Service (IaaS) Platform as a Service (PaaS) Software as a Service (SaaS)
  12. 12. Iaas-PaaS-SaaSIaaSPaaSSaaS
  13. 13. Infrastructure as a Service (IaaS) The IaaS layer gives the user an brief view on thehardware, which is computers, mass storagesystems, server, networks, etc. This is achieved by providing a user interface for the managementof a number of resources in the resource set sub-layer (RS). Physical resources using virtualization technologies such asXen, KVM, VMare.
  14. 14. Infrastructure as a Service (IaaS)OrganizationCloud Service DescriptionAmazonAmazon ElasticCompute Cloud (EC2)Provides users a special virtualmachine (AMI) that can bedeployed and run on the EC2infrastructureAmazonAmazon SimpleStorage Solution (S3)Provides users access todynamically scalable storageresourcesDropbox Dropbox Cloud storage Mass storage
  15. 15. Platform as a Service (PaaS) Its not targeted to the end users, but rather to developers. These are the programming environments (PE) and executiveenvironments (EE) where the programmer written in a specificprogramming language can be executed. Typical examples of programming environment are JavaFramework, Python, .NET, Ruby on Rails etc.
  16. 16. Platform as a Service (PaaS)Organization Cloud Service DescriptionGoogle Google App EnginePlatform to develop and run applicationson Google’s infrastructureMicrosoft Microsoft AzureOnline Operating System applicationFacebook Facebook PlatformEnvironment for the applications in theFacebook social network
  17. 17. Software as a Service (SaaS) It is directly address the end user. This model frees the customers from the need to install thesoftware locally as up – date done automatically. The SaaS offering can be developed and operated by theprovider on the basis of PaaS or IaaS offering
  18. 18. Software as a Service (SaaS)Organization Cloud Service DescriptionGoogle Google AppsWeb-based office tools such as e-mail,calendar and doc, spreadsheet, excelmanagement toolsSalesforce Salesforce.comFull customer relationship management(CRM) applicationMicrosoft Microsoft LiveMicrosoft office application

  20. 20. Why Cloud Computing Reduced Cost - Pay for What You Use Increase the Storage More Mobility Highly Automated Fast, Easy Implementation Accessible Support Staff Allows IT to Shift Focus

ExamplesAWS in Action - President Obamas successful re-election campaign• The 2012 US Presidential Election used AWS (Amazon S3 &Amazon RDS) to avoid an IT investment .They built and ran morethan 200 applications on AWS, scaled to support millions of users.One of these apps, the campaign call tool, supported 7,000concurrent users and placed over two million calls on the last fourdays of the campaign.Source:

  40. 40. SaaS vs. Hosting for Libraries: What’sthe Difference?SaaS: The software vendor or other provider owns the application(whether a discovery service, link resolver, ERM, or other) anddelivers it via the Internet.Libraries have the ability to customize the application for their ownuse via Web-based tools and an API.Hosting Model: The provider runs the application on the library’sbehalf, on the provider’s hardware, but doesn’t take on the task ofmaintaining the software. Upgrades and maintenance are up to thelibrary.
  41. 41. Multi-tenancy vs. Single-tenancy• One of the key differences between SaaS and hostingis the principle of tenancy .• With multi -tenancy, there is only one copy of thesoftware running, which accesses only one copy of thedatabase (information). Since multiple libraries shareand access this one instance of the software.• With Single- tenancy, each library maintains its owncopy of the software. Since each copy only serves onelibrary.

  50. 50. WorldCat Local It delivers one search box access to more than 969 million itemsfrom your library and the world’s library collections. Resources from 40+ national catalogs and partners like Googlebooks, HathiTrust, JSTOR and OAIster®. One search provides instant access to your library’s materials -digital objects, electronic materials, databases, e-journals, music,videos, audio, e-books, maps, journals, theses and books.Eg: INFLIBNET
  51. 51. ContentsWorldCat Local is the best way to get more than 969 million itemsfrom the world’s libraries in front of your users as per June 2012: Digital content: 29 million items E-books: 13 million Databases: 1764 Articles: 674 million Serials: 10 million IR content: 20 million items Evaluative content: 44 million items Books: 221 millionsource:
  52. 52. WorldCat Local A Powerful Library Application of Cloud Computing. It offers local searching, consortia searching, global searching,federated searching and meta searching, all bundled in ONESEARCH, NOT separate search. There is no hardware for your library to purchase, no softwarefor your library to install, nor any computer system for yourlibrary to operate.

He was speaking on the eve of the three-day 15thnational convention on Knowledge, Library and InformationNetworking. Source: In INDIAN Libraries, implementation of cloud computing isstarted. But it can be proven beneficial due to its cost effectivenessand effective service and thus can help to give new outlook toIndian Libraries
  58. 58. Cloud Computing In India NASSCOM research report entitled “Deconstructing the Cloud:The New Growth Frontier for Indian IT-BPO Sector”. Claimed by Big Commercial Companies (Amazon Web Services,Microsoft Azure Platform and Google Cloud Services). The study reveals that, cloud computing is expected to have asignificant impact on the services industry, in terms of servicesoffered, delivery mechanisms and business models. The Indianmarket for cloud computing is expected to grow in 2020.
  59. 59. Top 8 things to take away about cloudcomputing in the library context1. Understand what you are moving to the cloud2. Understand local legal requirements (national/state,institutional, etc.)3. Understand the costs of moving to the cloud4. Find a cloud provider you trust5. Articulate your requirements clearly6. Understand your SLA7. Get a lawyer involved8. Have an exit strategy

  64. 64. Cloud Quotes The correct answer is “both”. I do not think by 2020 people willwant to give up the autonomy and control they get by havingsoftware and data on their own device, but many of the servicethat we will expect...will require the power of a cloudsupercomputer.- by David D. Clark, American, Computer scientist The cloud will consist of a white part(trusted and checkedinformation), a grey part (question mark) and a black part(crapinformation: untrusted, unchecked, violent, fraudulent).by Marce Bullinga
