    Cloud Computing
  • Distributed Computing Challenges
    1) Scalability
    2) Availability
    End Users
    3) Maintenance
    4) Cost
    5) Security
  • A solution is needed!
  • The Little Story of Cloud Computing
    Once upon a time…
    • I’m Distributed Computing
    • I allow computations to run on several networked computers
    • I’m cool!
    • I’m Utility Computing
    • I package computing resources as a metered service
    • I’m economic
    They fell in love, and had a child…
    Cloud Computing
  • Cloud Computing is
    • A distributed computation model which offers managed, scalable, secured, highly-available computation resources and software as a service
    • The Cloud abstracts the complexity of software.
    • The Cloud is the INTERNET!
  • Cloud Components
    Clients

  • Cloud Infrastructure
    • Infrastructure as a service (IaaS)
    • Dynamic Scalability
    • Primary enabler is Virtualization technology
    • You pay for processing time you ACTUALLY use
    Commercial Examples
    • Amazon Elastic Computing Cloud (EC2)
    • Microsoft Azure Services Platform
  • Cloud Storage
    • Storage as a service
    • Scalable, Reliable and Highly Available
    • You pay for space and bandwidth you ACTUALLY use
    Commercial Examples
    • Amazon Simple Storage Service (S3)
    • Amazon SimpleDB
    • Microsoft Azure SQL Services
    • Microsoft Azure Simple Data Storage (SDS)
  • Cloud Platform
    • Solution stack to develop & deliver apps/services
    • Computing Platform as a service (PaaS)
    • Cloud Types: Instance & Fabric
    Commercial Examples
    • Amazon Simple Queue Service
    • Microsoft Azure .NET Services
    • Microsoft Windows Azure (IIS7, .NET 3.5,
    FastCGI)
  • Cloud Applications and Services
    • Cloud applications and services
    • Leverages the cloud infrastructure and platform
    • Live on the cloud, not on the user machine.
    • Services are consumed by
    • Other software components or,
    • End Users
    Commercial Examples
    • Web Apps (Facebook, YouTube)
    • SaaS (Google Apps)
    • PayPal, Google Maps
  • Cloud Clients
    • Hardware & Software which
    • Delivers cloud applications,
    • Consumes cloud services
    Commercial Examples
    • Web Browsers (IE, Firefox, Google Chrome)
    • Mobiles (iPhone, Android, Windows Mobile)
  • Other Cloud Providers
    GoogleApp Engine
    GoGrid Cloud Hosting
    Mosso Cloud Hosting
    Joyent Accelerators
  • The End.
