Which of the following is a key characteristic of cloud computing?

Scalability is a fundamental characteristic of cloud computing that refers to the system's ability to automatically scale resources up or down based on demand. In a cloud environment, resources such as computing power, storage, and network bandwidth can be dynamically allocated to match user or application needs. This allows businesses to handle varying workloads without manual intervention, ensuring efficient and cost-effective resource management. Option A (High latency) is incorrect because cloud computing aims to reduce latency by using distributed data centers and edge computing technologies. Option C (Fixed infrastructure) is incorrect because cloud computing infrastructure is dynamic and flexible, not fixed. Option D (Manual resource management) is incorrect because cloud computing focuses on automated resource provisioning and management. Option E (Limited accessibility) is incorrect because cloud computing promotes broad accessibility, allowing users to access resources from anywhere with an internet connection.
