  1. CLOUD COMPUTING Presented By: KALYANASISH SHEE (Roll- 10IT61K02) Department of Infotmation Technology Indian Institute of Technology Kharagpur INDIA -721302

  2. What is Cloud Computing • Cloud computing is a model for enabling convenient ,on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. (Source: NIST 2009) • A pool of abstracted, highly scalable, and managed compute infrastructure capable of hosting end-customer applications and billed by consumption. • The Fifth Generation of Computing (after Mainframe, Personal Computer, Client-Server Computing, and the web) • In Simple Terms, Cloud offers… • Virtually infinite computation resources • Pay-per-use for computation power • Automatic on-demand services KLYANASHISH SHEE Cloud Computing

  3. Where does the term “Cloud” come from ? Internet • “Cloud” is widely used as a metaphor for the Internet • Internet is the foundation of Cloud computing • based on the cloud drawing used in the past to represent the telephone network • later to depict the Internet in computer network diagrams as an abstraction of the underlying infrastructure it represents An Analogy – Electricity Grid • End-users consume power without needing to understand the component devices or infrastructure required to provide the service. • “Computation Power” is now available like Electricity • You rely on a trusted third-party providers • You pay for what you use. KLYANASHISH SHEE Cloud Computing

  4. What is a Cloud? SLAs Web Services Virtualization KLYANASHISH SHEE Cloud Computing

  5. Cloud computing characteristics • Provides computation, software, data access, and storage services. • End-user do not require knowledge of the physical location and configuration of the system that delivers the services. • Encompasses any pay-per-use or subscription-based service that, in real time over the Internet. • Users can access to remote computing sites using web-based tools or applications through the Internet. • Though softwares reside at remote servers but it looks like to users as if the softwares were installed locally on their own computers. • Services are delivered through shared data-centers and appearing as a single point of access for consumers' computing needs. • Service-level agreements (SLAs) may require for commercial offerings. KLYANASHISH SHEE Cloud Computing

  6. Cloud computing characteristics (Contd.) • Application programming interface (API) enables machines to interact with cloud software in the same way the user interface facilitates interaction between humans and computers. • Reduced cost in a public cloud delivery model. • No need to develop infrastructure as is provided by a third-party. • Pricing on a utility computing basis, pay and use when required. • Fewer IT skills are required for implementation. • Device and location independence • Users can get service from anywhere through internet. • End users access systems using a web browser regardless of what device they are using (e.g., PC, mobile phone). KLYANASHISH SHEE Cloud Computing

  7. Cloud computing characteristics (Contd.) • Reliability is improved if multiple redundant sites are used, suitable for disaster recovery. • Performance is monitored, and consistent and loosely coupled architectures are constructed using web services. • Security of could is improved due to centralization of data, increased security-focused resources, etc • Maintenance is easier, as nothing to maintain on each user's computer.

  8. Cloud Computing Models *Source: http://itechthoughts.wordpress.com/2010/02/23/cloud-computing-the-new-it-paradigm/ KLYANASHISH SHEE Cloud Computing

  9. Cloud Computing Models (Contd.) IaaS – Infrastructure as a Service • Provides infrastructure capabilities like processing, networking, storage, security, and other resources which allow consumers to deploy their applications and data. • Lowest level provided by the Cloud Computing paradigm. • Examples: Amazon/EC2, VMWare vCloud. PaaS – Platform as a Service • Provides application infrastructure such as programming languages, database management systems, applications servers, web servers, etc. that allow applications to run. • Users need not manage the underlying platform including, networking, operating system, storage, etc. • Supports web development interfaces as Service Oriented Architecture (SOAP). • Examples: Google App Engine, ORACLE/AWS. KLYANASHISH SHEE Cloud Computing

  10. Cloud Computing Models (Contd.) SaaS – Software as a Service • Provides the end-user software applications through a web browser (could also be though a rich client). • Hides all the underlying details of networking, storage, database management systems, application servers, operating system, etc. from the consumer. • Examples: Salesforce CRM, Oracle CRM On Demand, Microsoft Online Services, and Google Apps. KLYANASHISH SHEE Cloud Computing

  11. Cloud Computing Models (Contd.) KLYANASHISH SHEE Cloud Computing

  12. Cloud Computing Models (Contd.) • XaaS – Everything as a Service • All functionalities of cloud computing is considered as Service • AIaaS – Application Infrastructure as a Service • Provides application middleware, including applications servers, ESB, and BPM (Business Process Management). • APaaS – Application Platform as a Service • Provides application servers with added multitenant elasticity as a service. • DaaS – Desktop as a Service • Provides desktop standardization, pay-per-use, management, and security based on application streaming and virtualization technology. KLYANASHISH SHEE Cloud Computing

  13. Cloud Computing Models (Contd.) • BPaaS – Business Process as a Service • Provides business processes such as billing, contract management, payroll, HR, advertising, etc. as a service. • CaaS – Communications as a Service • Provides anagement of hardware and software required for delivering instant messaging, video conferencing, VOIP for both fixed and mobile devices • NaaS – Network as a Service • Allows telecommunication operators to provide network communications, billing, and intelligent features as services to consumers.

  14. Types of Cloud Computing KLYANASHISH SHEE Cloud Computing

  15. Types of Cloud Computing • Public Clouds • Resources are dynamically provisioned to the general public on a self-service basis over the Internet • Based on the ubiquity of the internet. • Provides all the benefits of the economy of scale, ease of management, and ever growing elasticity • Major concern about this style of deployment is security KLYANASHISH SHEE Cloud Computing

  16. Types of Cloud Computing (Contd.) • Private Clouds • Infrastructure is operated solely for a single organization, whether managed internally or by a third-party and hosted internally.or externally. • A new form of architecture for the Datacenter, sometimes mentioned as a Datacenter-in-a-box. • VMWare is using this type of cloud through their products vCloud, vCenter, and vSphere. • Hybrid Clouds • Combination of private clouds and public clouds that remains unique entities but is bound together, offering the benefits of multiple deployment models. • Managed using the same administration and monitoring consoles (therefore, the importance of cloud standardization).

  20. Cloud computing: the latest evolution of hosting KLYANASHISH SHEE Cloud Computing

  21. Example: Google AppEngine • Development tool for Web apps on Google infrastructure • Does not operate in stand-alone mode like EC2 • Developers hand over code; Google checks request logs, monitor status of app, push new versions, integrate pieces • Access to Other Apps • Google Sites (collaboration) and Google Apps • APIs into Google Earth, Maps, Images, OpenSocial, etc • How to use • Download AppEngine SDK • Develop your program locally • A set of python programs, input = requested url, output = return message • Debug locally • Register for an application id • Submit your application to Google KLYANASHISH SHEE Cloud Computing

  22. Google AppEngine –Hello world • Creating a Simple Request Handler Create a file helloworld.py: Print‘Content-Type: text/plain‘ print'‘ print'Hello, world!‘ • Map url to handler Edit configuration file app.yaml application: helloworld version: 1 handlers: -url: /.* script: helloworld.py • Data storage: • Distributed file system • Store using AppEngine API, retrieve using GQL • •Debug: http://localhost:8080/ KLYANASHISH SHEE Cloud Computing

  23. Cloud Apps: Web 2.0, SaaS, Remote apps • Remote desktop applications • Run on top of underlying cloud infrastructure platforms • SaaS providers • Run on top of underlying cloud infrastructure platforms • CRM, ERP, VoIP, BI, supply chain • Web 2.0 • interconnectivity and interactivity of • web-delivered content • New Services exploiting underlying platforms KLYANASHISH SHEE Cloud Computing

  24. Future Trends and Prospects • Cloud Computing is the fastest growing part of IT • Hybrid cloud computing is the future direction of cloud computing and increasingly hybrid cloud products are being offered • IBM recently acquired Cast Iron Systems to provide support for hybrid clouds. • Microsoft emphasized the hybrid cloud at TechEd, OpenNebula recently released a Datacloud adaptor for Hybrid clouds • Estimated size of the cloud computing is $42B infrastructure market in 2012 KLYANASHISH SHEE Cloud Computing
