The document provides an overview of cloud computing, defining it as a model for delivering IT services over the internet with various service types including SaaS, PaaS, and IaaS. It discusses key characteristics, comparisons with other computing models, current user demographics, and examples of companies utilizing cloud solutions, particularly highlighting Eli Lilly's efficiencies gained through cloud adoption. The presentation also mentions legal issues surrounding the branding of cloud computing and concludes with a Q&A session.

1. Cloud Computing Presented by Nhan Nguyen

2. Outline Cloud Terms Comparisons Many Flavors of Cloud Computing Key Characteristics Architecture Type Who’s using Clouds today? Example: Eli Lilly Legal Issues 1

3. What is “Cloud”? There is no clear definition of the term “Cloud” or “Cloud Computing” No Official Definition Term takes on the definition of the user Overuse the term “cloud” by eager marketer 2

4. What is “Cloud”? There are two popular uses of the term “cloud” in today’s I.T. conversation Cloud Services - consumer and business products, services and solutions that are delivered and consumed in real-time over the internet Cloud Computing - an emerging IT development, deployment, and delivery model that enables real-time delivery of a broad range of IT products, services and solutions over the internet 3

5. Cloud Computing is an Evolution in IT 4

6. Comparisons Grid Computing – a form of distributed computing, acting in concert to perform very large tasks Utility Computing – a metered service similar to a traditional public utility such as electricity Autonomic Computing – capable of self-management Cloud Computing – deployments as of 2009 depend on grids, have autonomic characteristics and bill like utilities 5

7. Cloud Formation 6 Cloud Computing is an emerging IT development, deployment and delivery model, enabling real-time delivery of products, services and solutions (i.e., enabling cloud services) over the Internet (IDC) Cloud computing is Internet based development and use of computer technology. It is a style of computing in which typically real-time scalable resources are provided as a service over the internet (Wikipedia) Cloud: the new home and business network

8. Many Flavors of Cloud Computing SaaS – Software as a Service Network-hosted application PaaS– Platform as a Service Network-hosted software development platform IaaS – Infrastructure as a Service Provider hosts customer VMs or provides network storage 7

9. Many Flavors of Cloud Computing (cont’d) DaaS – Data as a Service Customer queries against provider’s database IPMaaS – Identity and Policy Management as a Service Provider manages identity and/or access control policy for customer NaaS – Network as a Service Provider offers virtualized networks (e.g. VPNs) 8

10. Cloud Computing Providers 9

11. The Cloud’s “Snowball Effect” Maturation of Virtualization Technology Virtualization enables Compute Clouds Compute Clouds create demand for Storage Clouds Storage + Compute Clouds create Cloud Infrastructure Cloud Infrastructure enables Cloud Platforms & Applications 10

12. Cloud “Applications” SaaS resides here Most common Cloud / Many providers of different services Examples: SalesForce, Gmail, Yahoo! Mail, Quicken Online Advantages: Free, Easy, Consumer Adoption Disadvantages: Limited functionality, no control or access to underlying technology 11

13. Cloud “Platforms” “ Containers”, “Closed” environments Examples : Google App Engine, Heroku, Mosso, Engine Yard, Joyent or Force.com (SalesForce Dev Platform) Advantages: Good for developers, more control than “Application” Clouds, tightly configured Disadvantages: Restricted to what is available, other dependencies 12

14. Cloud “Infrastructure” Provide “ Compute ” and “ Storage ” clouds Virtualization layers (hardware/software) Examples : Amazon EC2, GoGrid, Amazon S3, Nirvanix, Linode Advantages: Full control of environments and infrastructure Disadvantages: premium price point, limited competition 13

15. Key Characteristics 14

16. Colo vs. Managed vs. Cloud Hosting 15

17. Architecture Types 16

18. Single-Tenant vs. Multi-Tenant Architecture 17 Single tenancy gives each customer a dedicated software stack – and each layer in each stack still requires configuration, monitoring, upgrades, security updates, patches, tuning and disaster recovery. On a multi-tenant platform, all applications run in a single logical environment: faster, more secure, more available, automatically upgraded and maintained. Any improvement appears to all customers at once.

19. Who’s using Clouds today? Startups & Small businesses Can use clouds for everything Mid-Size Enterprises Can use clouds for many things Large Enterprises More likely to have hybrid models where they keep some things in house 18

20. Example: Eli Lilly Reduced costs Global access to R&D applications Rapid transition due to VM hosting Time to deliver new services greatly reduced: New server: 7.5 weeks down to 3 minutes New collaboration: 8 weeks down to 5 minutes 64 node linux cluster: 12 weeks down to 5 minutes 19

21. Legal Issues March 2007, Dell applied trademark “cloud computing”. September 2008, Cgactive LLC received trademard “CloudOS” November 2007, Affero GPL open source code April 2009, FBI raided a data center 20
