The definition of "cloud" in cloud computing can be described as the set of hardware, storage, services, networks, and interfaces that join together to supply aspects of computing as a service. Cloud services incorporate data storage over the Internet, infrastructure, and delivery of software based on end user demand.
There are four vital aspects of cloud computing:
1. Flexibility and the capacity for scaling up and down.
2. Application Programming Interfaces (APIs)
3. Self-support provisioning and mechanized deprovisioning.
4. A pay-as-you-go model for billing and metering of service usage.
Cloud computing is available in multiple forms such as; private clouds, public clouds, and a combination of the two - called a hybrid.
People that use cloud computing services are:
- Cloud service providers who manage IT assets and maintenance.
- Business executives who must be accountable for the management of their services and data being stored on the cloud. Cloud providers must make sure their networks are stable and secure.
- Personal users that are not aware of the behind the scenes technology in place.
Businesses that use cloud computing have found that it can eradicate a large amount of complicated obstacles that traditional computing comes with, including time, space, cost and power - completely changing the way they are using technology to service their clients. But, there is a down side if the company you choose does not have proper security or their servers go down. It may be best to use cloud only as a back-up for redundancy.
