Vertical Scaling

Vertical scaling, also known as scaling up, refers to the process of increasing the capacity of a single server or machine to handle greater loads by adding more resources, such as CPU, RAM, or storage. This approach enhances performance by allowing a single system to manage increased demand without the need for additional machines, making it simpler to maintain and manage. However, it is limited by the maximum capacity of the hardware and can lead to a single point of failure.
