Utility computing encapsulates the following characteristic(s)
a) Mobility amalgamation
b) No impact on resource utilization
c) Pay-per-use pricing business model
d) None of above
The correct answer and explanation is:
The correct answer is c) Pay-per-use pricing business model.
Utility computing refers to the delivery of computing services, such as processing power, storage, or software, through a “pay-per-use” model. This model allows users to pay for computing resources based on their consumption, much like how utilities like water or electricity are billed. This model contrasts with traditional computing setups, where companies have to buy and maintain their own hardware and software infrastructure upfront.
In utility computing, resources are typically provided by a third-party service provider, such as cloud services (e.g., Amazon Web Services, Microsoft Azure, or Google Cloud). These services scale to meet the user’s demand, allowing users to increase or decrease their computing needs without making large capital investments. Instead of paying a flat rate or maintaining a fixed infrastructure, customers pay for only the amount of resources they use, which can significantly reduce costs.
The key benefits of utility computing are scalability, flexibility, and cost efficiency. With the pay-per-use model, users can scale up or down based on their immediate needs, and they do not have to worry about idle resources, which can reduce waste and unnecessary expenses. This dynamic model is also attractive to businesses, as it eliminates the need for upfront capital investment in infrastructure, making it easier for smaller companies to access computing power and services that they would not typically be able to afford.
In summary, utility computing is built on the pay-per-use pricing model, allowing businesses and individuals to pay only for the computing resources they consume, which is one of its primary advantages.
