Answer:
Cloud computing's characteristics and benefits include on-demand self-service, broad network access, and being very elastic and scalable. As cloud computing services mature both commercially and technologically, it will be easier for companies to maximize the potential benefits.
Explanation:
Cloud is a model of computing where servers, networks, storage, development tools, and even applications (apps) are enabled through the internet. Instead of organizations having to make major investments to buy equipment, train staff, and provide ongoing maintenance, some or all of these needs are handled by a cloud service provider.
There are five key characteristics of a cloud computing environment, as defined by the National Institute of Standards and Technology (NIST):
Internet Access
- With a public cloud environment, users "plug into" the data and applications via an internet connection giving anytime, anywhere access.
Measured Service
- Cloud is often pay-as-you-go, where you only pay for what you use. Think about how a utility company meters how much water, electricity, or gas is used and charges based on consumption. The cloud is the same.
On-Demand Self-Service
- Services can be requested and provisioned quickly, without the need for manual setup and configuration.
Shared Resource Pooling
- Cloud often uses the multi-tenancy model. This means a single application is shared among several users. So, rather than creating a copy of the application for each user, several users, or "tenants" can configure the application to their specific needs.
Rapid Elasticity
- Cloud platforms are elastic. An organization can scale its resource usage levels up or down quickly and easily as needs change.
