Database Scaling

1. Methods of Scaling

1.1 Vertical Scaling (Scale-up)

In Vertical Scaling, we increase the CPU, RAM, and Storage or buy a more robust server in order to support more traffic and load on our database server.

1.2 Horizontal Scaling (Scale-out)

In Horizontal Scaling we add more systems with the smaller configuration in terms of CPU, RAM and Storage to distribute the traffic or load across these systems.
