      Cloud Computing
    • 3. Introduction
      • The term is New ,but the Concept is old
      • The term was already in use from the 90s and the Concept dates back to 1960s.
      • Actual adoption started in 21 st century in relation to online computing.
      • New class of Internet Technology
      • Allows individuals and businesses to work online rather than on a PC.
      Cloud Computing
    • 4.
      • Cloud Computing existed in various forms for
      • many years.
      • It was limited by factors such as
            • Internet speeds
            • Reliability of websites
            • Reliability of remote servers
            • Cost
      Cloud Computing
    • 5. What is Cloud Computing?
      • Cloud computing is location-independent computing, whereby shared servers provide resources, software, and data to computers and other devices on demand, as with the electricity grid.
      • Cloud computing is a natural evolution of the widespread adoption of virtualization, service-oriented architecture and utility computing .
      Cloud Computing
    • 6. History Cloud Computing
    • 7. Key Features
      • Agility: improves with users' ability to rapidly and inexpensively re-provision technological infrastructure resources.
      • Cost: is claimed to be greatly reduced and capital expenditure is converted to operational expenditure.
      • Device and location independence: As infrastructure is off-site and accessed via the Internet, users can connect from anywhere.
      • Maintenance of cloud computing applications
      • is easier, since they don't have to be installed on
      • each user's computer.
      Cloud Computing
    • 8. Key Features
      • Metering means that cloud computing resources usage should be measurable and should be metered per client and application on a daily, weekly, monthly, and yearly basis.
      • Electronic Recycling The costs of electronic recycling are shifted to the hands of the cloud provider.
      • Multi-tenancy enables sharing of resources and costs across a large pool of users thus allowing for: Centralization of infrastructure
      • Peak-load capacity increases
      • Utilization and efficiency improvements
      • for systems
      Cloud Computing
    • 9. Architecture
      • The two most significant components of cloud computing architecture :
          • Front end
          • Back end
      • The Front end is the part seen by the client, i.e. the computer user. This includes the client’s network (or computer) and the applications used to access the cloud via a user interface such as a web browser.
      • The Back end of the cloud computing architecture
      • is the ‘cloud’ itself, comprising various computers, servers and data storage devices.
      Cloud Computing
    • 10. Cloud Computing
    • 11. Service Models
      • Cloud computing can come in many forms depending on the type of service it provides.
      Cloud Computing
    • 12. SaaS – Software as a Service
      • Cloud application services or " Software as a Service ( SaaS ) " deliver software as a service over the Internet, eliminating the need to install and run the application on the customer's own computers and simplifying maintenance and support.
          • Network or Online Access – SaaS is an online application or at least, a network based application.
          • Centralized Management – control, monitoring and update could be done in a single location.
          • Powerful Communication Features – mere fact that
          • SaaS is often used online provides a strong backbone for Instant Messaging (Chat) or even voice calls (VOIP).
      Cloud Computing
    • 13. PaaS – Platform as a Service
      • Cloud platform services or " Platform as a Service ( PaaS ) " deliver a computing platform and/or solution stack as a service, often consuming cloud infrastructure and sustaining cloud applications.
      • It facilitates deployment of applications without the cost and complexity of buying and managing the underlying hardware and software layers.
      Cloud Computing
    • 14. IaaS –Infrastructure as a Service
      • Cloud infrastructure services, also known as " Infrastructure as a Service ( IaaS ) ", delivers computer infrastructure - typically a platform virtualization environment - as a service.
      • Rather than purchasing servers, software, data-center space or network equipment, clients instead buy those resources as a fully outsourced service.
      Cloud Computing
    • 15. dSaaS-Data Storage as a service
      • Cloud Data Storgae services, also known as “ data Storage as a Service ( dSaaS )", delivers robust, cloud-based suite of storage - as a service.
      • Reduced risk through secure backup, storage, information protection.
      • Reduced costs through the elimination of capital investments for archived digital storage.
      • Rapid access to information for legal discovery, r egulato ry compliance, audits, business continuity and disas ter recovery
      Cloud Computing
    • 16. Deployment Models
      • The various Cloud models includes :
      Cloud Computing
    • 17. Public Cloud
      • Public cloud or external cloud describes cloud computing in the traditional main stream sense, whereby resources are dynamically provisioned on a fine-grained, self-service basis over the Internet, via web applications/web services, from an off-site third-party provider who bills on a fine-grained utility computing basis.
      • Example:
      • Amazon EC2
      Cloud Computing
    • 18. Private Cloud
      • Private cloud ,also called internal cloud or corporate cloud provides hosted services to a limited number of systems and applications internally to an organization.
      • A form of cloud computing where the customer has some control/ownership of the service implementation.
      • Examples:
        • NASA’s NEBULA
        • VMWare
        • Citrix
        • NATO private cloud
      Cloud Computing
    • 19. Hybrid Cloud
      • A standard definition of the term has not yet emerged.
      • The most correct definition of the term "hybrid cloud" is probably the use of physical hardware and virtualized cloud server instances together to provide a single common service.
      • A hybrid storage cloud uses a combination of public and private storage clouds. Hybrid storage clouds are often useful for archiving and backup functions, allowing local data to be replicated to a public cloud
      Cloud Computing
    • 20. Community Cloud
      • A community cloud may be established where several organizations have similar requirements and seek to share infrastructure so as to realize some of the benefits of cloud computing.
      • With the costs spread over fewer users than a public cloud this option is more expensive
      • may offer a higher level of privacy, security and/or policy compliance.
      • Example: Google's "Gov Cloud"
      Cloud Computing
    • 21. Cloud Computing
    • 22. Migrating to Cloud
      • Cloud computing is greatly considered today by most businesses.
      • business will enjoy mobility without being held down to a single application.
      • Local vs. Vendor Offered Cloud Computing
      • Proper Selection of Cloud Computing Provider
      Cloud Computing
    • 23. Proper Selection of provider
      • Research – before you start shopping for a provider, understand what you need first in cloud computing and what you could get from a provider.
      • Physical Visit – as much as possible pay a visit to the company’s actual data center and/or server farm.
      • The Worst Case Scenario – always look for information or ask the vendor on how they deal with certain situations that will affect your business process.
      • Ability to Upgrade – it is an imperative for a vendor to expect upgrades from their clients.
      Cloud Computing
