I disagree, it feels more like Cluster Autoscaling to me.

I thought it was Horizontal Scaling at first.

Vertical Scaling means adding resources to existing instances, right?

Wait, are we sure it's not Recursive Scaling? Sounds fancy!

I thought cluster autoscaling was related to managing multiple instances, but this seems more about enhancing individual instances, so maybe it's vertical scaling?

I practiced a similar question where we discussed scaling types, and I believe vertical scaling is when you increase the capacity of existing machines.

I'm not entirely sure, but I remember something about horizontal scaling being about adding more servers, so this feels like the opposite.

I think this might be vertical scaling since we're adding more resources to each instance instead of adding more instances.

I'm a little confused here. Is this horizontal or vertical scaling? I'll have to review my notes to be sure.

Vertical scaling, for sure. Increasing the resources of each individual instance is the definition of vertical scaling.

Okay, I remember learning about this in class. Allocating more resources to each instance is definitely vertical scaling.

Recursive Scaling? Is that even a thing? Sounds like something straight out of a sci-fi movie. I'm going with Vertical Scaling, it's the classic choice.

Vertical Scaling it is then. Let's stick with the traditional approach.

Cluster Autoscaling? Really? What is this, some kind of futuristic solution? I'll stick with the good old-fashioned Vertical Scaling, thank you very much.

I'm pretty sure this is Vertical Scaling. I mean, who wants to deal with the complexity of Horizontal Scaling when you can just throw more resources at the problem?

I'm not sure, but I think it might be Cluster Autoscaling. That way, resources can be dynamically allocated based on demand.

That makes sense too. It could be either D) Vertical Scaling or A) Horizontal Scaling depending on how you look at it.

But wouldn't horizontal scaling be more efficient in this case? It allows you to add more instances to handle the increased load.
