What are the differences between vertical and horizontal scaling?

What are the differences between vertical and horizontal scaling?

Vertical scaling means adding more power (CPU, RAM) to an existing machine, while horizontal scaling involves adding more machines.

Can you give me examples of when to use each type?

Sure! Use vertical scaling for applications that require high performance on a single server, like databases. Use horizontal scaling for web applications that need to handle many users simultaneously.

What are the advantages and disadvantages of each?

Vertical scaling is simpler but can be limited by hardware constraints. Horizontal scaling offers better redundancy and can handle more traffic but requires more complex architecture.

Which one is more cost-effective?

It depends on the use case. Vertical scaling can be cheaper initially, but horizontal scaling can be more cost-effective in the long run for large-scale applications.
