Cloud service
Software as a Service (SaaS) Software on demand & subscription based licensing. E.g.: Microsoft Office 365, Google Apps etc.Advantages: No need to purchase software & their frequent updates. Eliminates the data center cost. High scalability. Disadvantages: Dependency on the service provider.

Cloud service
Platform as a Service (PaaS) Platform to develop, maintain and run applications without maintaining the infrastructure, middleware frameworks, database etc. E.g.: Windows Azure, AWS etc.Advantages: Various benefits in application testing & deployment. Backup & recovery as a part of service. Highly scalable and dynamic allocation based on geo-locations. Disadvantages: Data security Integrating PaaS with in-house systems.`

Cloud service
Infrastructure as a Service (IaaS) Infrastructure, dedicated or virtual servers. E.g.: Windows Azure, Amazon EC2 etc.Advantages: Various resources like firewalls, load balancer, VM disk image etc. Highly scalable infrastructure. Disadvantages: Off-premise data storage.

Application features required for Cloud
Architecture should not be specific to any topology Designed to take advantage of parallel architecture of cloud Design should consider the quantity of data transferred to the various clients (i.e. mobile, web etc.) as client may have limited bandwidth Data security is a major concern, so proper measures should be taken Service-Oriented architecture should be adopted

Application migration planning
Analyzed technically for performance, design, data security etc. Enterprise should consider the compliance issues, security concerns etc.
