Reply To: Spot Fleet with Diversified Allocation Strategy – with Auto Scaling Enabled?

[JR-TutorialsDojo]

Hello virasana,

Thanks for reaching out to us.

Automatic scaling is supported for Spot Fleet through a combination of AWS services: Amazon EC2, CloudWatch, and Application Auto Scaling.

While Spot Fleet doesn’t have built-in Auto Scaling like ASGs, you can enable automatic scaling by:

• Creating a Spot Fleet request via Amazon EC2
• Defining CloudWatch alarms to monitor metrics like CPU utilization
• Configuring scaling policies using Application Auto Scaling

https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/spot-fleet-automatic-scaling.html

So, in the context of the given question, the answer refers to using a Spot Fleet with a diversified allocation strategy and enabling automatic scaling per AZ, which is entirely valid, even if the scaling mechanism is external to the fleet itself.

Hope that helps clarify!

Best regards,
