  3. IT resources and services that are abstracted from the underlying infrastructure and provided “on-demand” and “at scale” in a multi-tenant environment Today, clouds are associated with an off-premise, hosted model 3 © 2009 Cisco Systems, Inc. All rights reserved. Cisco Confidential

  4. How Big is the Cloud Opportunity? Total Spending on Cloud-Based Services $42B 27% CAGR $16B Cloud Services projected to grow at 5x the rate of current Enterprise IT spending Source: IDC, 10/2008 4 © 2009 Cisco Systems, Inc. All rights reserved. Cisco Confidential

  7. Architectural Service Layers of Cloud Computing • Each layer encapsulates on-demand resources • Each layer comes with its own application development model • Three service layers: • Software as a Service (SaaS) • Platform as a Service (PaaS) • Infrastructure as a Service (IaaS) 7 © 2009 Cisco Systems, Inc.

  8. Software as a Service (SaaS) Cloud provider offers software services that are of potential interest to a wide variety of users Users (optionally) buy subscription to software products Software implemented by cloud provider on their own infrastructure Instances of the software run on cloud provider infrastructure and serve multiple client organizations Some or all of the data resides remotely Examples: SalesForce.com, Google Mail, Google Docs 8 © 2009 Cisco Systems, Inc.

  9. Platform as a Service (PaaS) Cloud provider offers a platform upon which developers provide services that are of potential interest to a wide variety of users Users (optionally) buy subscription to software products Software implemented by developers to run on the cloud provider infrastructure Instances of the software run on cloud provider infrastructure and serve multiple client organizations Some or all of the data resides remotely Examples: Google Apps Engine, Amazon Web Services (w/ basic web stack) 9 © 2009 Cisco Systems, Inc.

  10. Infrastructure as a Service (IaaS) Cloud provider offers IT infrastructure (compute, storage, network, etc.) to customers Virtualization is leveraged to dynamically combine resources in order to build and deliver ad hoc systems to the customer Customers deploy their own software environment (i.e. virtual machine images) to run on these systems Resources used by customers can grow and shrink on demand Some or all of the data resides remotely Examples: Amazon Web Services (EC2 and S3) 10 © 2009 Cisco Systems, Inc.

  11. Who Are the Major Cloud Players? APPLICATION (SaaS) PLATFORM AS A SERVICE (PaaS) INFRASTRUCTURE AS A SERVICE (IaaS) IT FOUNDATION 11 © 2009 Cisco Systems, Inc. All rights reserved. Cisco Confidential
