The correct answer is D. all of the mentioned.
Cloud computing is the on-demand delivery of IT resources over the Internet with pay-as-you-go pricing. Instead of buying, owning, and maintaining physical data centers and servers, you can access technology services, such as computing power, storage, and databases, on an as-needed basis from a cloud provider like Amazon Web Services (AWS).
Cloud computing offers a number of advantages over traditional IT infrastructure, including:
- Cost savings: Cloud computing can help you save money on IT costs by eliminating the need to purchase and maintain your own hardware and software. You only pay for the resources you use, and you can scale your usage up or down as needed.
- Agility: Cloud computing can help you be more agile by giving you the ability to quickly deploy new applications and services. You can also easily scale your resources up or down to meet changing demand.
- Reliability: Cloud computing providers offer a high level of reliability by using redundant systems and data centers. This means that your applications and data are always available, even in the event of a disaster.
- Security: Cloud computing providers offer a high level of security by using industry-leading security measures. Your data is protected from unauthorized access and malicious attacks.
The three unique attributes of cloud computing are:
- Utility type of delivery: Cloud computing provides IT resources as a service, which can be accessed on demand and paid for only when used. This is similar to how utilities such as electricity and water are delivered.
- Elasticity: Cloud computing resources can be easily scaled up or down to meet changing demand. This means that you only pay for the resources you use, and you can add or remove resources as needed.
- Low barrier to entry: Cloud computing makes it easy for businesses of all sizes to access IT resources. There is no need to purchase or maintain your own hardware and software, and you can start using cloud services quickly and easily.
In conclusion, the correct answer to the question “Which of the following is one of the unique attributes of Cloud Computing?” is D. all of the mentioned.
