What is a key feature of cloud infrastructure?

Static server allocation
Dynamic resource allocation
Manual scaling of resources
Single tenant environments

The correct answer is: Dynamic resource allocation

Dynamic resource allocation is a key feature of cloud infrastructure because it allows for the automatic adjustment of resources based on demand. In a cloud environment, resources such as computing power, storage, and network bandwidth can be scaled up or down in real-time without the need for human intervention. This flexibility ensures that applications can efficiently handle varying workloads, optimize performance, and reduce costs. In contrast, static server allocation does not provide the necessary adaptability for fluctuating demands and would not be appropriate in a cloud context where efficiency and responsiveness are paramount. Manual scaling of resources reduces the efficiency and speed at which resources can be adapted to meet current needs, leading to potential delays and increased operational costs. Single tenant environments are typically associated with dedicated resources for a single client, which limits the scalability and cost-effectiveness that multi-tenant cloud infrastructures offer. Therefore, dynamic resource allocation is essential for maximizing the benefits of cloud computing.
