What is the difference between horizontal and vertical scaling in cloud computing?

Horizontal and vertical scaling are two different methods for increasing the capacity of a cloud computing system. Horizontal scaling involves adding more instances of the same resource, while vertical scaling involves increasing the capacity of a single resource. Horizontal scaling, also known as scaling out, involves adding more instances of the same resource, such as adding more servers to a cluster. With horizontal scaling, the workload is distributed across the additional resources, which helps to increase the overall capacity of the system. This approach is often used to handle large workloads and to improve the availability and resilience of the system. Horizontal scaling is typically achieved through load balancing, where incoming requests are distributed across multiple instances of the resource. Vertical scaling, also known as scaling up, involves ....
