Explanation :Are gadgets important?
As wireless technology gets better and cheaper, more and more different kinds of objects will connect directly to the cloud.

Four Cloud Deployment Models
Private cloud Enterprise owned or leased
Community cloud Shared infrastructure for specific community
Public cloud Sold to the public, mega-scale infrastructure
Hybrid cloud Composition of two or more clouds
Hybrid Cloud

On-demand self-service
Broad network access
Resource pooling
Rapid elasticity
Measured service
Five Essential Cloud Characteristics
Allows business units to get the computing resources they need without having to go through IT for equipment.
Enables applications to be built in ways that align with how businesses operate today - mobile, multi-device, etc.
Allows for pooling of computing resources to serve multiple consumers.
Allows for quick scalability or downsizing of resources depending on demand.
Business units only pay for the computational resources they use.

GENERAL CHALANGES
Trusting vendor’s security model Customer inability to respond to audit findings Obtaining support for investigations Indirect administrator accountability Loss of physical control

Conclusion Companies have to pick and choose and be careful with
what data they allow to be out there in a cloud. Cloud computing can be a useful resource to help
companies save money but can also have downfalls. As companies perfect their cloud computing services, I
think that more companies will be open to using these services.
This service will provide new inventive ways to use computers and provide services.
