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
Cloud Computing
They fell in love, and had a child…

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!

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 Infrastructure

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 SimpleDBMicrosoft Azure SQL Services Microsoft Azure Simple Data Storage (SDS)
Cloud Storage

Solution stack to develop & deliver apps/services Computing Platform as a service (PaaS) Cloud Types: Instance & Fabric
Commercial Examples Amazon Simple Queue ServiceMicrosoft Azure .NET Services Microsoft Windows Azure (IIS7, .NET 3.5, FastCGI)
Cloud Platform

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 Applications and Services
