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