The correct answer is C. Cloud computing.
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 benefits over traditional IT infrastructure, including:
- Cost savings: You only pay for the resources you use, and you can scale your usage up or down as needed.
- Increased agility: You can quickly deploy new applications and services without having to invest in new hardware or software.
- Improved reliability: Cloud providers offer a high level of uptime and redundancy, so you can be confident that your applications will be available when you need them.
- Enhanced security: Cloud providers offer a range of security features and services that can help you protect your data and applications.
Cloud computing is a rapidly growing market, and it is expected to continue to grow in the coming years. According to a report by Gartner, the global cloud services market is expected to reach $482 billion by 2022.
Here is a brief explanation of each option:
- Remote sensing is the acquisition of information about an object or phenomenon, without making physical contact with the object. It is used in a wide range of applications, including weather forecasting, environmental monitoring, and military reconnaissance.
- Remote invocation is a technique used in distributed computing to allow a client program to call a method on a server program without having to know the location of the server. This is done by using a proxy object that acts as an intermediary between the client and server.
- Private computing is a type of computing that is used by a single organization or individual. It is typically used to protect sensitive data or to run applications that require a high level of security.
