cloud computing

  1. 1. COUD COMPUTING SHRUTI GUPTA Department of Computer Science
  2. 2. What is Cloud Computing ?  Cloud ????????????
  3. 3. Cloud + Computing  Cloud : Mass of infrasstructure.  Computing: computing part * platform as a service * infrastruce as a service
  4. 4. GRID COMPUTING Emerging enables tchnology  Natural evaluation of distributed system and Internet.  Middleware supporting network of system to facilitate sharing standandardization and openness.  Infrastructure and application model dealing with sharing of compute cycles,data,storage and other resources. 
  5. 5. Limitaions of grid computing Explosive growth in application biomedical informatics, space exploration, business analytics  Expenotial growth in compute capabilities: multi core,storage,bandwidth virtual machine  Very short cycle of obscenest in technology: windows 7-window8, java versions; c-C#; python 
  6. 6. Answer is cloud computing Cloud computing environment can provide one or more of software these requirements for a cost.  Pay as you go model of business.  When using a public cloud the model is similar to renting the property than owning one.  An organization may also maintain a private cloud and use both 
  7. 7. What is cloud computing Provide a variety of computing resources, from servers and storage to enterprise applications such as email, security, backups all deliver over the internet. It deliver a hosting environment that is immediate,flexiable, scalable,secure,and available while saving corporation money, time, resources
  8. 8. Cloud computing is combination of Grid, virtulization, utility, automatic computing.
  9. 9. Cloud Computing    Shared pool of configurable computing resources On-demand network access Provisioned by the Service Provider Adopted from: Effectively and Securely Using the Cloud Computing Paradigm by peter Mell, 10 Tim Grance
  10. 10. eg Hotmail – first in application software Amazon- first in infrastructure as a storage devices ,data storage area Google-gdrive,microsoft- office 365
  11. 11. Characteristics of cloud computing
  12. 12. Types of cloud Location based 1.public 2. private 4.hybrid  Types of Services 1. Software as a Service(SaaS) 2.Platform as a Services(PaaS) 3.Infrastructure as a Service(IaaS) 
  13. 13. Cloud Software as a Service (SaaS) Service Models Platform as a Service (PaaS) SalesForce CRM LotusLive Google App Engine Adopted from: Effectively and Securely Using the Cloud Computing Paradigm by peter Mell, 14 Tim Grance Infrastructure as a Service (IaaS)
  14. 14. Cloud component Client  Data center(collection of servers where the application to which you subscribe is hosted )  Internet 
  15. 15. Virtual Machines VM technology allows multiple virtual machines to run on a single physical machine App App Guest OS (Linux) VM App Guest OS (NetBSD) VM App App Guest OS (Windows) VM Virtual Machine Monitor (VMM) / Hypervisor Hardware . Xen VMWare UML Denali etc. Performance: Para-virtualization (e.g. Xen) is very close to raw physical performance! 16
  16. 16. Advantages of cloud computing Lower computer cost  Improved performance  Reduce software cost  Instance software update  Improved document compatibility  Unlimited data storage  Data reliability  Device independence 
  17. 17. Disadvantages of cloud computing Constant internet connection  Does not work well with low-speed connections  Features might be limited   Each cloud systems uses different protocols and different APIs
  18. 18. Future of cloud computing
