What does vertical scaling imply in cloud infrastructure management?

Vertical scaling refers to the process of adding more resources to an existing server to enhance its capabilities. This often includes upgrading the hardware, such as increasing the CPU, RAM, or storage capacity, to improve the performance of applications running on that server. By adding these resources, a single server can handle more workloads or support more demanding applications, leading to improved performance without the need to manage multiple servers.

This approach contrasts with horizontal scaling, where additional servers are added to distribute the workload. In the context of cloud infrastructure management, vertical scaling can be particularly useful when applications are designed to run on single instances or when the overhead of managing multiple servers is undesirable. This type of scaling allows for quick adjustments in resource allocation based on current demand, making it a viable option in cloud environments where flexibility and rapid response to changes in workload are essential.
