AWS Fargate – Run Containers Without Managing Infrastructure

I'm a bit confused by the wording on the T2 unlimited post:

> T2 Unlimited instances have the ability to borrow an entire day’s worth of future credits, allowing them to perform additional bursting.

What does this mean? Specifically, what is meant by "borrow"? Do they have to be paid back? Does the next day then have fewer credits?

Instead of ever being throttled your instance accumulates a "borrowed" CPUSurplusCreditBalance. If your CPU Utilization goes back below the threshold, the earned credits will pay down the surplus balance. If you terminate an instance with a nonzero CPUSurplusCreditBalance you'll be charged for the extra usage.

We removed the direct relationship between credits and 24h cycles, so your current usage no longer affects tomorrow's balance: https://forums.aws.amazon.com/ann.jspa?annID=5196
