3. Easy to upgrade.
4. Infinite scale.
5. Much lower cost than vertical scaling

Disadvantage of Horizontal Scaling: -

1. Extra Equipment are required such as router, Switches.
2. Architecture is complicated.
3. High licensing fees.
4. High utility cost
5. Limited number of software available that can take of horizontal scaling.

Vertical Scaling: — Vertical scaling usually mean upgrade server hardware according to our need. vertical scaling refers to scaling by adding more power (e.g. CPU, RAM) to an existing machine.
