Cloud computing provides on-demand, scalable access to shared computing resources via the internet. It has three main service models - Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). Major cloud providers include Amazon (IaaS), Microsoft Azure (PaaS), and Salesforce (SaaS). The document discusses key characteristics, deployment models, security aspects, and the promise of cloud computing for enabling flexible, efficient, and scalable IT services.

100. Cloud Computing The Promise…The Future… A Simple Idea Clear Tenets..the principles behind User Builds a Web based business application, Using a standard platform Using a standard database Upload this application to a cloud provider Only pays for what s/he uses when s/he needs it. Everything else is an implementation detail. Cloud provider automatically Provisions the services Scales the application and the database together Application Flexibility: Standardized Increasing “click to run” services Live in remote Internet data centers Scalable to millions System Replication Procurement: Efficient Rapid Commoditized “Pay by the sip” Security: Simplified Streamlined Cloud Multi-faceted Enablement Infrastructure: Consolidation Global Information Grid Capacity Services Virtualization Rapid Provisioning Facility Analysis Software: Network-centric Services System Monitoring Services Help Desk/Support Services SaaS Processes: SAS 70, ITIL , ISO 1779/9000 Customer: SOX, HIPAA, FISMA Security (C&A) Computing Service Provider (CSP) 8/26/2010 17 Version 1.0
