View CPU burst capacity accrual for Lightsail instances
Did you know?
You can change your instance bundle to a larger size when you create an instance from an instance snapshot. For more information, see Upsize a Lightsail instance, storage, or database from snapshots .
Amazon Lightsail instance plans accrue 4.17% of CPU burst capacity per hour, except for Linux or Unix $380 and larger plans, and Windows $570 and larger plans. The maximum CPU burst capacity that can be accrued is equivalent to the amount of CPU burst capacity percentage that can be earned in a 24-hour period. Your instance stops accruing CPU burst capacity when the CPU burst capacity percentage reaches 100%.
Important
Accrued CPU burst capacity
-
Linux or Unix $380 and Windows $570 and larger instance plans – These plans don't accrue CPU burst capacity. They will burst automatically, as needed.
-
Instances created before June 29, 2023 – CPU burst capacity does not persist if your instance is stopped. If you stop your instance, it loses all accrued burst capacity.
-
Instances created on or after June 29, 2023 – CPU burst capacity persists for seven days between instance stops and starts.
-
Accrued CPU burst capacity on a running instance does not expire.
Lightsail instances receive additional CPU burst capacity at launch, this is called launch CPU burst capacity. Launch CPU burst capacity allows instances to burst immediately after launch before they have accrued additional burst capacity. Launch CPU burst capacity does not count towards the burst capacity limit. If your instance has not spent its launch CPU burst capacity, and remains idle over a 24-hour period while accruing more burst capacity, its CPU burst capacity (percentage) metric graph will appear as over 100%.
Additionally, some Lightsail instances start in launch mode, which temporarily removes some of the performance limitations that are typically present on burstable instances. Launch mode allows you to run resource-intensive scripts at launch without affecting the overall performance of your instance.
