A new media company uses a mobile app to provide news and information services. They utilize Auto Scaling to add/reduce ECS instances dynamically to address service traffic spikes.

Based on the estimation of their service and technical personnel the company thinks they require 10 ECS instances during idle hours and 10 to 20 ECS instances (dynamically adjusted) during some busy hours, which are normally from 07:30 to 09:00 and from 18:30 to 20:00 In the scaling group; they set the "Minimum number of instances" to 10 and "Maximum number of instances" to 20.

Wait, they're not using the 'Hilarious mode' to keep their users entertained during the busy hours? I'm disappointed.

Ah, the 'Event-triggered mode' could work, but it might be overkill for their use case. 'Scheduled mode' is the simple and cost-effective choice here.

Hmm, 'Fixed quantity mode' might work, but it doesn't sound flexible enough to handle the dynamic traffic patterns. 'Scheduled mode' is the way to go!

Yeah, 'Fixed quantity mode' might not be able to adjust to the changing traffic demands like 'Scheduled mode' can.

Agreed, 'Scheduled mode' allows for setting specific times for scaling which aligns with their busy hours.

Based on the requirements, I think they should choose the 'Scheduled mode'. It allows them to pre-configure the scaling actions to automatically adjust the instance count during the busy hours.
