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