Explanation:
Detailed explanation-1: -There are two basic types of scalability in cloud computing: vertical and horizontal scaling. With vertical scaling, also known as “scaling up” or “scaling down, ‘’ you add or subtract power to an existing cloud server upgrading memory (RAM), storage or processing power (CPU).
Detailed explanation-2: -Through vertical scaling (scaling up or down), you can increase or decrease the capacity of existing services/instances by upgrading the memory (RAM), storage, or processing power (CPU). Usually, this means that the expansion has an upper limit based on the capacity of the server or machine being expanded.
