    Cloud Computing Demystified Cloud Computing Demystified Presentation Transcript

    • Demystified
      Prepared by: SamerMeqdad
      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.
