12.
How’d That Cloud Get There? <ul><ul><li>Data centres are idle 85% of the time! </li></ul></ul><ul><ul><ul><li>Over-provisioning? </li></ul></ul></ul><ul><ul><ul><li>Redundancy is a must… </li></ul></ul></ul><ul><ul><ul><li>What if that natural disaster never happens? </li></ul></ul></ul><ul><ul><li>This new model offers significant advantages for fast-paced startups, SMBs & enterprises alike. </li></ul></ul><ul><ul><li>Cost effective solutions to key business demands. </li></ul></ul><ul><ul><li>Move workloads to improve efficiency. </li></ul></ul>

19.
5 Essential Characteristics <ul><li>On-demand self-service </li></ul><ul><li>Broad network access </li></ul><ul><li>Resource pooling </li></ul><ul><ul><li>Location independence </li></ul></ul><ul><li>Rapid elasticity </li></ul><ul><li>Measured service </li></ul>

20.
4 Deployment Models <ul><li>Internal (Private) Cloud : The cloud infrastructure is operated within the organization. </li></ul>Main Office + Branches Data Centre

21.
4 Deployment Models <ul><li>Community Cloud : The cloud is jointly owned by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). </li></ul>Stakeholders Data Centre Internet or Extranet

22.
4 Deployment Models <ul><li>Public Cloud : The cloud infrastructure is owned by an organization selling cloud services to the general public/companies. </li></ul>Public MegaCorp Data Centre Internet

23.
4 Deployment Models <ul><li>Hybrid Cloud : Two or more clouds (internal, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability. </li></ul>Main Office + Branches Internal Data Centre Stakeholders MegaCorp Data Centre Internet or Extranet

24.
3 Service Models <ul><li>Software as a Service (SaaS) </li></ul><ul><ul><li>Use provider’s applications over a network </li></ul></ul><ul><li>Platform as a Service (PaaS) </li></ul><ul><ul><li>Deploy customer-created applications to a cloud </li></ul></ul><ul><li>Infrastructure as a Service (IaaS) </li></ul><ul><ul><li>Rent processing, storage, networking, and other basic computing resources </li></ul></ul>
