In the context of cloud computing, which statement is true regarding its relationship with distributed computing?

Cloud computing can be understood as an extension of distributed computing because it builds upon the principles and technologies that underlie distributed systems. Distributed computing refers to a model where computing resources are distributed across multiple machines or locations, often working together to complete tasks that could be performed on a single system. This approach aims to improve performance, reliability, and resource utilization.

Cloud computing utilizes the framework of distributed computing, providing users with scalable resources that can be accessed via the internet. It leverages distributed architectures to offer services such as storage, computing power, and applications, which can be dynamically allocated based on demand. This flexibility and the ability to scale resources rapidly are key attributes of both distributed and cloud computing.

The other options present a misunderstanding of the relationship between the two concepts. Claiming that cloud computing completely replaces distributed computing ignores the foundational role that distributed computing plays in enabling cloud services. Suggesting that they are unrelated fails to recognize the critical dependency of cloud computing on distributed systems. Lastly, stating that cloud computing is a less efficient form of distributed computing mischaracterizes cloud computing, as it actually aims to optimize efficiency and resource allocation through its design and operational approaches.
