Infrastructure as a Service (IaaS)
The capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, and deployed applications; and possibly limited control of select networking components (e.g., host firewalls).
Benefits
Systems managed by SLA should equate to fewer breaches
Higher return on assets through higher utilization
Reduced cost driven by Less hardware Less floor space from smaller hardware footprint Higher level of automation from fewer administrators Lower power consumption
Able to match consumption to demand
Challenges
Portability of applications
Maturity of systems management tools
Integration across the Cloud boundary
Extension of internal security models
