Cloud Computing - Abhijeet

  1. 1. CLOUD Made by : Abhijeet Singh
  2. 2. Made by : Abhijeet Singh
  3. 3.  A way of computing, via the Internet.  Shares computer resources instead of using software or storage on a local PC.  No need to install documents, software, Operating system.  A physical storage center is no longer needed.  A way to access Applications hosted on the web through your web browser.  Consist of Virtual Platform (OS) , Software and infrastructures.  Only need is High-Speed Internet. Made by : Abhijeet Singh
  4. 4. Made by : Abhijeet Singh
  5. 5.  SaaS  Software-as-a-Service  PaaS  Platform-as-a-Service  IaaS Infrastructure-as-a-Service Made by : Abhijeet Singh
  6. 6.  It's all On Demand  Rich Internet application web sites  Application as Web Sites  Collaboration and email  Office Productivity  Client apps that connect to services in the cloud • Eg: Flikr,, Cisco WebEx office, Gmail, IBM
  7. 7.  Virtual Development-platform-as-a-service  Database  Message Queue  App Servicer  Reduce cost of buying & managing S/w & H/w Example : Google App Engine, Microsoft SQL Server Data Services, Engine Yard,’s
  8. 8.  Backbone of Entire system  Virtual servers  Physical storage space  Processing capabilities  Logical disks  VLAN networks  Systems Management Eg: Akamai, Amazon EC2, CohesiveFT, Mosso, Joyent Accelerators
  9. 9. 1) Cost  Greatly reduced Cost on purchasing diff kinds of Software , operating system etc.  No need to be purchased for one-time or infrequent computing tasks.  Pricing of any services is compute on usage-based options  Fewer IT skills are required for implementation (in-house) 2) Device  Location independence enable to access systems using web browser  Regardless of their location or device they are using (e.g PC, mobile).  Accessed via the Internet, users can connect from anywhere. Made by : Abhijeet Singh
  10. 10. 3) Security  Improve due to centralization of data  More Focus on resources, etc.  Security is greatly increased when data is distributed over a no. of devices & Area. 4) Reliability  Utilization and efficiency improvements for systems that are often only 10–20% utilized.  Suitable for Business continuity and disaster recovery.  IT and business managers can at times do little when they are affected. 5) Maintenance Applications are easier to maintain, since they don't have to be installed on each user's computer. Easier to support and to improve since the changes reach the clients instantly.

  16. 16. 1) Grid Computing Collection of servers that are clustered together to attack a single problem.  Form of distributed/ parallel computing is composed of a cluster of networked loosely coupled computers acting in concert to perform very large tasks.  If one piece of software on a node Fails, other pieces of s/w on other nodes may fail. Example : Scientific Research 2) Cloud computing A narrower form of client-server, between service providers (servers) and service requesters (clients) where the details of the server are abstracted . For example:- one may not connect to a specific server. However, due to the popularity of the cloud metaphor, "cloud computing" may be used to refer to any form of client-server computing.

  18. 18. 1) Public cloud  Public / External cloud describes cloud computing in the traditional mainstream sense.  Resources are dynamically provide on a self-service basis over the Internet, via web applications/web services  an off-site third-party provider who shares resources and bills. 2) Private cloud  Private / Internal cloud are being used by some organization or group of people on private networks.  Deliver some benefits of cloud computing without the pitfalls  Data security, corporate governance, and reliability concerns.  Users have to buy, build, and manage them. Example : PNB, HDFC, SBI Bank Cloud. Made by : Abhijeet Singh
  19. 19. 3) Community cloud  Established by several organizations to have Similar Requirements  To share Infrastructure of the cloud computing.  Collaborate together to perform bigger tasks/ operations.  More expensive  Higher level of privacy, security or policy compliance. Examples: Google's "Gov Cloud". 4) Hybrid cloud  Environment consisting of multiple internal or external providers.  Users may be able to ease the transition to Public services.

  20. 20.  Your data is not directly in your hands, but in the hands of a third party.  Total Dependence on the Internet Connection. If your cloud Host disappears, where does your information go? Made by : Abhijeet Singh
  21. 21. Mobile Cloud Computing  Network-as-a-Service  Platform-as-a-Service Made by : Abhijeet Singh
