CAuto Scaling

DOSS

Suggested Answer: A

Server Load Balancer (SLB) is a service that distributes network traffic across multiple ECS instances to improve the service capabilities of applications. By using SLB, you can increase the availability and fault tolerance of your applications. You can also use SLB with Auto Scaling to dynamically adjust the number of ECS instances based on the traffic load. Multiple lower-configuration I/O-optimized ECS instances can be used with SLB to deliver a high-availability architecture that can handle traffic spikes and reduce costs.

I'm a bit confused about RDS and its role in this context. I thought it was more about databases than instance management.

I practiced a similar question last week, and I think Auto Scaling was the answer there too. It makes sense for managing instances.

I feel like we discussed Server Load Balancer in class, but I can't recall how it fits with I/O-optimized ECS instances.

I think I remember something about using Auto Scaling for high availability, but I'm not entirely sure if it's the best choice here.
