Alex: Isn’t scale-up and scale-out the same thing?
Harold: No. Let me first tell you about scalability, and then I will go into this difference. Scalability is the ability of a system to grow or shrink in a graceful manner. It allows it to function continuously when conditions such as traffic or volume change. Some examples could be how efficiently a system performs when user traffic is increased multifold, how well a database responds to a higher volume of queries, or even how an operating system performs on different types of hardware.
So, a scalable system must perform with the same stability and performance, even if the load on it increases. It can obviously take advantage of increased resources and offer better performance to customers.
And that means the performance of a system is directly related...
