Vertical Scaling
Vertical scaling upgrades a single machine with more CPU, RAM, or faster storage — simpler but capped by hardware limits.

In Depth
Vertical scaling (scaling up) means making a single server more powerful by adding CPU cores, RAM, or faster SSD storage — without adding more machines.
