What is the difference between vertical and horizontal autoscaling?

What is the difference between vertical and horizontal autoscaling?

Vertical autoscaling involves adding more resources (like CPU or RAM) to a single server, while horizontal autoscaling adds more servers to handle increased load.

Which one is better for cloud applications?

It depends on the application. Vertical scaling is simpler but has limits, while horizontal scaling offers better redundancy and can handle more traffic.

Can you give me an example of when to use each?

Sure! Use vertical scaling for applications with a single-threaded workload, and horizontal scaling for web applications that need to handle many simultaneous users.

What are the costs associated with each type?

Vertical scaling can be cost-effective initially, but as you reach hardware limits, it can become expensive. Horizontal scaling may have higher initial costs but can be more economical in the long run.
