Better spend OPEX than CAPEX

CAPEX+OPEX=TCO (Total Cost of Ownership)

Definition of Cloud Computing

Cloud Computing Principals

On demand self service
The consumer can provision computing capabilties, without requiring human interaction on service provider side.

Broad Network Access
Capabilities are available over the network and access through standard mechanisms that promote use by heterogeneous thin or thick client platfomrs(e.g. mobile phones, tablets, laptops, etc.)

Ressource pooling (multi-tenancy)
The providers’s computing ressources are pooled to serve multiple customers using a multi-tenant model, with different physical and virtual ressources dynamically assigned and reassigned according to consumer demand.
Location independance and customer usually has no controll over the exact location where his services are running.
Broader areas like continent, country or DC maybe be chosen by the customer.

Rapid elasticity
Capabilities can be elastically provisioned and released, in some cases automatically, to scale rapidly outward and inward commensurate with demand. to the consumer, the capabilities available for provisioning often appear to be unlimited and can be approproprieted in any quantity at any time.

Measured service (pay-as-you-go)
Cloud systems automatically control and optimize resource use by leveraging a metering capabiltity at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Ressource usage can be monitored, controlled and reported, providing transparency for both the provider and consumer of the utilized service.

Cloud Computing Service Models

Software as a Service (SaaS)
Platform as a Service (PaaS)
Infrastructure as a Service (Iaas)
