Description: Scaling Up is the process of adding resources to a single node to increase its capacity. This approach is commonly used in cloud computing environments, where more CPU, RAM, or storage can be added to an existing server to enhance its performance. Unlike horizontal scaling, which involves adding more nodes or servers to a system, vertical scaling focuses on maximizing the capacity of a single node. This technique is particularly useful in situations where applications or services require high performance and are not designed to distribute their workload across multiple instances. Vertical scaling can be easier to implement, as it does not require significant changes to the application architecture. However, it has limitations, such as cost and the possibility of reaching a physical limit on hardware capacity. In the cloud, Infrastructure as a Service (IaaS) providers allow users to scale vertically flexibly, adjusting resources according to current needs. This translates into more efficient resource management and cost optimization, as users only pay for what they actually use.
