Vertical scaling
Handling more load by giving one machine more power
What's it for?
Handles more work by making one existing computer more powerful.
For example…
A database server is vertically scaled from 8 GB to 32 GB of memory so it can handle a heavier workload without adding another machine
An application needs more processing power, so its existing virtual machine is upgraded to more CPUs rather than adding extra application instances
Think of it like…
Using a double-decker bus to carry more passengers rather than adding a second bus to the route
