1. Service Models
USER CLOUD a.k.a. SOFTWARE AS A SERVICE
Single application, multi-tenancy, network-based, one-to-many delivery of
applications, all users have same access to features.
Examples: Salesforce.com, Google Docs, Red Hat Network/RHEL
DEVELOPMENT CLOUD a.k.a. PLATFORM-AS-A-SERVICE
Application developer model, Application deployed to an elastic service that
autoscales, low administrative overhead. No concept of virtual machines or
operating system. Code it and deploy it.
Examples: Google AppEngine, Windows Azure, Rackspace Site, Red Hat
Makara, AWS RDS
SYSTEMS CLOUD a.k.a INFRASTRUCTURE-AS-A-SERVICE
Servers and storage are made available in a scalable way over a network.
Examples: EC2,Rackspace CloudFiles, OpenStack, CloudStack,
Eucalyptus, Ubuntu Enterprise Cloud, OpenNebula, Vcloud
2. What is CloudStack?
• Secure, multi-tenant cloud
orchestration platform
– Turnkey platform for delivering
IaaS clouds
Build your cloud the way the – Hypervisor agnostic
world’s most successful clouds
are built – Scalable, secure and open
– Open source, open standards
– Deploys on premise or as a hosted
solution
• Deliver cloud services faster
and cheaper

Editor's Notes
CloudStack works within multiple enterprise strategies and mandates, as well as supporting multiple cloud strategies from a provider perspective. As an initial step beyond traditional server virtualization, many organizations are looking to private cloud implementations as a means to satisfy flexibility while still retaining control over service delivery. The private cloud may be hosted by the IT organization itself, or sourced from a managed service provider, but the net goals of total control and security without compromising SLAs is achieved.For some organizations, the managed service model is stepped up one level with all resources sourced from a hosted solution. SLA guarantees and security concerns often dictate the types of providers an enterprise will look towards. At the far end of the spectrum are public cloud providers with pay as you go pricing structures and elastic scaling. Since public clouds often abstract details such as network topology, a hybrid cloud strategy allows IT to retain control over key aspects of their operations such as data, while leveraging the benefits of elastic public cloud capacity.
