Cloud computing

  1. 1. CLOUD COMPUTING BY:-Chhavi narayan Chiranjit Mallik C.Kavya D Sunil kumar Chandran S R Chandra sekhar reddy
  2. 2. CONTENT CLOUD COMPUTING SERVICES Cloud Architecture ADVANTAGES DISADVANTAGES CLOUD COMPUTING AT IBM CONCLUTION
  3. 3. WHAT IS CLOUD COMPUTING Cloud computing is a type of computing that relies on sharing computing resources rather than having local servers or personal devices to handle applications.
  4. 4. CLOUD COMPUTING SERVICES  Software as a Service (SaaS)-End Users  Infrastructure as a Service (IaaS)-Application Developers  Platform as a Service (PaaS)- Network Architects
  5. 5. SOFTWARE AS A SERVICE-END USERS  Is an application that can be accessed from anywhere on the world as long as you can have an computer with an Internet Connection.  We can access this cloud hosted application without any additional hardware or software.  E.g. : G-mail, Yahoo mail, Hotmail etc..,  Also they can provide security features such as SSL encryption, a cryptographic protocol.
  6. 6. PLATFORM AS A SERVICE PAAS)  Application developers can develop and run their software solutions on a cloud platform without the cost.  With some PaaS offers, the underlying computer and storage resources scale automatically to match application demand so that the cloud user does not have to allocate resources manually.  The latter has also been proposed by an architecture aiming to facilitate real- time in cloud environments.  E.g.: Salesforce.com, Windows Azure etc.
  7. 7. INFRASTRUCTURE AS A SERVICE (IAAS)  Also known as hardware as a service.  Is a computing power that you can rent for a limited period of time.  Allows existing applications to be run on a cloud suppliers hardware.  Cloud providers offer computers – as physical or more often as virtual machines –, raw (block) storage, firewalls, load balancers, and networks
  8. 8. CLOUD ARCHITECTURE
  9. 9. MODES OF CLOUDS Public Cloud • Computing infrastructure is hosted by cloud vendor at the vendors premises. • and can be shared by various organizations. • E.g. : Amazon, Google, Microsoft, Sales force  Private Cloud • The computing infrastructure is dedicated to a particular organization and not shared with other organizations. • more expensive and more secure when compare to public cloud. • E.g. : HP data center, IBM, Sun, Oracle, 3tera  Hybrid Cloud • Organizations may host critical applications on private clouds. • where as relatively less security concerns on public cloud. • usage of both public and private together is called hybrid cloud.
  10. 10. ADVANTAGES Cost Efficiency Convenience and continuous availability Increased Storage Capacity Backup and Recovery
  11. 11. DISADVANTAGES:-  Security and privacy in the cloud  Technical Difficulties and Downtime  Limited control and flexibility
