The Little Story of Cloud Computing
 I’m Utility Computing
 I package computing resources as a metered service
 I’m economic
 I’m Distributed Computing
 I allow computations to run on several networked computers
 I’m cool
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 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)
