Vertical Scaling (Scaling Up)

Category: infrastructure

The process of adding more power (RAM, CPU, SSD) to an existing machine.

Scaling up is the "hero" approach. You replace your small server with a massive, high-performance one. It’s easier to implement than horizontal scaling, but you eventually hit a "physical wall" where no single server can get any faster or bigger.

Common Examples

• We performed vertical scaling on our main database node to handle the intense IO requirements of the month-end batch reports.
• While vertical scaling is a fast initial fix, we prioritize horizontal scaling for our long-term growth and fault-tolerance architecture.
