When we try, we see a message “Request for 2 c4.xlarge maximum EC2 instances exceeds the limit of 1 available.” like the picture below.

Another picture below, shows “Scaling” tab in Fleet information.

So how can we change the numbers? and what are criteria of auto-scaling up?

Go to Amazon GameLift -> Service Limits. It should show your current usage and and limits for EC2 instance types
- Look at whats allocated to fleets. Do you have enough to scale up?
- If not, release capacity
- If you can’t release capacity then file a support issue for a limit increase in the region(s) and for the instance types required
- If yes, then your account may be restricted (if its a new AWS account); by default you should have access to 15
- Cut a support issue for a limit increase for region(s) and instances. GameLift will then work with you and AWS support to unrestrict accouunt.
