The correct answer is D. all of the mentioned.
Reliability is the ability of a system to perform its required functions under stated conditions for a specified period of time. Productivity is the efficiency with which goods and services are produced. Abstraction is the process of hiding the details of implementation and exposing only the essential features.
In the context of cloud computing, reliability is important because it ensures that users can access their data and applications when they need them. Productivity is important because it allows users to get more done with less effort. Abstraction is important because it makes it easier for users to use cloud services without having to understand the underlying technology.
Here are some additional details about each of the concepts:
- Reliability: A reliable system is one that is able to perform its required functions under stated conditions for a specified period of time. This means that the system should be able to handle the expected load, and it should not crash or experience other problems that prevent it from providing the required services.
- Productivity: A productive system is one that allows users to get more done with less effort. This means that the system should be easy to use, and it should provide features that help users to be more efficient.
- Abstraction: Abstraction is the process of hiding the details of implementation and exposing only the essential features. This makes it easier for users to use a system without having to understand how it works. In the context of cloud computing, abstraction is important because it allows users to use cloud services without having to understand the underlying technology.
