Cloud Computing Service ModelsUSER CLOUD a.k.a. SOFTWARE AS A SERVICESingle application, multi-tenancy, network-based, one-to-many delivery of SaaS applications, all users have same access to features.Examples: Salesforce.com, Google Docs, Red Hat Network/RHELDEVELOPMENT CLOUD a.k.a. PLATFORM-AS-A-SERVICEApplication developer model, Application deployed to an elastic service thatautoscales, low administrative overhead. No concept of virtual machines or PaaS operating system. Code it and deploy it.Examples: Google AppEngine, Windows Azure, Rackspace Site, Red HatMakaraSYSTEMS CLOUD a.k.a INFRASTRUCTURE-AS-A-SERVICEServers and storage are made available in a scalable way over a network. IaaS Examples: EC2,Rackspace CloudFiles, OpenStack, CloudStack,Eucalyptus, Ubuntu Enterprise Cloud, OpenNebula 5. Deployment ModelsPublic, Private & Hybrid Clouds 6. Cloud Still RequiresArchitectural Design Cloud Computing isnt a magicalsolution apps need to be able toscale out Design your architecture with theend in mind Make your infrastructure easilyreplicable 7.

Scale-Up or Scale-OutVertical Scaling (Scale-Up) Allocate additional resources toVMs, requires a reboot, no needfor distributed app logic, single-point of OS failureHorizontal Scaling (Scale-Out) Application needs logic to workin distributed fashion (e.g. HA-Proxy and Apache, Hadoop) 14.
