I disagree with Delfina. It is possible to set up rules to allow communication between ECS instances in different Security Groups.

Wait, are we sure about this? I mean, it's Alibaba Cloud, maybe they do things differently over there. Can't be too careful, right?

I think it's true, separate Security Groups usually mean no communication between instances.

True. I think instances in different Security Groups are isolated from each other for security reasons.

Really? I thought this was supposed to be a cloud computing exam, not a trick question. The answer is clearly 'False', everyone knows that.

Haha, good one! Next they'll be telling us instances in different Availability Zones can't talk to each other. Come on, that's basic networking!

I agree with Kristel. Security Groups can be configured to allow communication between instances.

That's not true at all! Security Groups are used to control network access, not to isolate instances completely. Of course instances in different Security Groups can communicate, as long as the rules allow it.
