2019/11/25 - Amazon Elastic Compute Cloud - 2 new api methods
Changes This release adds two new APIs: 1. ModifyDefaultCreditSpecification, which allows you to set default credit specification at the account level per AWS Region, per burstable performance instance family, so that all new burstable performance instances in the account launch using the new default credit specification. 2. GetDefaultCreditSpecification, which allows you to get current default credit specification per AWS Region, per burstable performance instance family. This release also adds new client exceptions for StartInstances and StopInstances.
Modifies the default credit option for CPU usage of burstable performance instances. The default credit option is set at the account level per AWS Region, and is specified per instance family. All new burstable performance instances in the account launch using the default credit option.
ModifyDefaultCreditSpecification is an asynchronous operation, which works at an AWS Region level and modifies the credit option for each Availability Zone. All zones in a Region are updated within five minutes. But if instances are launched during this operation, they might not get the new credit option until the zone is updated. To verify whether the update has occurred, you can call GetDefaultCreditSpecification and check DefaultCreditSpecification for updates.
For more information, see Burstable Performance Instances in the Amazon Elastic Compute Cloud User Guide .
