Scaling Differences

They’re both valid scaling techniques, but they both have different limitations on the affected system.

Horizontal Scaling

• Involves adding more machines or instances to your infrastructure.
• Increases capacity by connecting multiple hardware or software entities so they work as a single logical unit.
• Often used in distributed systems and cloud environments.

Vertical Scaling

• Involves adding more resources (CPU, RAM, storage) to an existing machine.
• Increases capacity by enhancing the power of a single server or instance.
• Limited by the maximum capacity of the hardware.

In summary, horizontal scaling adds more machines to handle increased load, while vertical scaling enhances the power of existing machines.
