Question

How to check if my EC2 instance is burstable? (AWS)

I'm using Launch template it only said "Instance type t2.micro".

T2, T3, T3a, and T4g - Are they always burstable or should I specify "T2-burstable" / "T2-not-burstable"?

Answer 1

all the t instances type are burstable, an instance is considered bursting when its cpu usage goes above the following thresholds:

• nano 5%
• micro 10%
• small 20%
• medium 20%
• large 30%
• xlarge 40%
• 2xlarge 40%

if an instance consumes all its CPU credits it gets throttled at those same values.

to avoid this you can run your instance in unlimited mode for a little fee

Answer 2

All of the t2, t3, t3a, t4g instances are burstable
