What is the process of scaling up resources such as CPU and RAM referred to as?

• A. Horizontal scaling
• B. Vertical scaling
• C. Pooling
• D. Elasticity

Answer: (B)

The process of scaling up resources such as CPU and RAM is referred to as vertical scaling. This approach involves adding more power to an existing machine by increasing its resources, allowing it to handle larger workloads or more demanding applications. Vertical scaling is particularly useful for applications that require high performance and low latency, as it enables the system to operate more efficiently. In contrast, horizontal scaling refers to adding more machines or nodes to distribute the workload, effectively increasing the capacity without necessarily enhancing the existing machines' capabilities. Pooling generally refers to the aggregation of resources, like storage or compute, for more efficient allocation but does not specifically describe the action of increasing resources within a single instance. Elasticity describes the ability of a system to automatically adjust resources based on current demand, which can involve both scaling up and down, but does not directly specify the action of adding resources to a single instance. Thus, vertical scaling is the most accurate terminology for the scenario presented in the question.
