Cloud Computing

  1. 1. Mumbai
  2. 2. Lokesh Raghani Vaibhav Kubadia
  3. 3. The cloud, is an expression used to describe a variety of different types of computing concepts that involve a large number of computers connected through a real-time communication network (typically the Internet). What is cloud
  4. 4. Computing includes – designing, developing and building hardware and software systems – processing, structuring, and – managing various kinds of information by doing scientific research on and with computers; and creating and using communications and entertainment media. What is computing
  5. 5. Introduction • Cloud Computing means a type of Internet-based computing, where different services such as servers, storage and applications are delivered to an organization's devices through the Internet. • It’s a collection of networked hardware, software and Internet infrastructure.
  6. 6. • Shared pool of configurable computing resources • On-demand network access • Provisioned by the Service Provider
  7. 7. • Remotely hosted • Ubiquitous • Low Cost Software • On Demand Self-Service • Resilient Computing • Pay as much as you use Characteristics
  8. 8. Software as a Service (SaaS) • SaaS uses the Web to deliver applications that are managed by a third-party vendor and whose interface is accessed on the clients’ side. • Most SaaS applications can be run directly from a Web browser, without any downloads or installations required. • Gmail is one famous example of an SaaS mail provider.
  9. 9. Platform as a Service (PaaS) • Developers gain with PaaS is a framework they can build upon to develop or customize applications. • PaaS makes the development, testing, and deployment of applications quick, simple, and cost-effective. • Similar to the way that you might create macros in Excel, PaaS allows you to create applications using software components that are controlled by a third-party vendor. • PaaS is highly scalable , and users don’t have to worry about platform upgrades or having their site go down during maintenance.
  10. 10. Infrastructure as a Service• (IaaS) • Cloud infrastructure services, known as “Infrastructure as a Service”• (IaaS), deliver computer infrastructure (such as a platform virtualization environment), storage, and networking. • Instead of having to purchase software, servers, or network equipment, users can buy these as a fully outsourced service. • Compared to SaaS and PaaS, IaaS users are responsible for managing more: applications, data, runtime. • What users gain with IaaS is infrastructure on top of which they can install any required platforms. Users are responsible for updating these if new versions are released.
  11. 11. Cloud Service Models
  12. 12. Software as a Service (SaaS) Platform as a Service (PaaS) Infrastructure as a Service (IaaS) Google App Engine SalesForce CRM LotusLive Examples of Models
  13. 13. • Less Infrastructure • Data on the platform • Applications on the cloud Purpose & Benefits
  14. 14. Cloud computing works using economies of scale: • It potentially lowers the expense for start up companies • Cost would be by on-demand pricing Opportunities
  15. 15. • Dependence on others • There are also issues relating to policy and access: › What happens if the remote server goes down? › How will you then access files? › What in cases of users being locked out of accounts and losing access to data? • Performance and High Bandwidth Cost Challenges
  16. 16. • Instant software updates and that too online • Latest version availability • No obsolete software and high upgrade costs • Unlimited storage capacity • Increased data reliability • Universal document access Advantages
  17. 17. • Requires a constant Internet connection • Low Speed connections • Features might be limited • Sometimes can be slow • Stored data can be lost Disadvantages
  18. 18. • $180 billion Estimated global cloud services market by the end of 2015 • $131 billion Estimated global cloud services market by the end of 2013 • 50 million Number of physical servers in the world • 60% Server workloads that will be virtualized in 2013 • 48% Percentage of the cloud market spent on advertising in 2012 • 21% Annual savings of users who move apps to the cloud • 1/3 IT budgets to be spent on cloud computing in 2013 Statistics As on 5th September 2013
