A throughput mode is an EFS filesystem configuration that sets maximum data-transfer behavior and associated cost. EFS provides Bursting and Provisioned modes. section 9.5 section 9.5.2
Choose between these operating models:
- Bursting provides a storage-dependent baseline, accumulates burst credits when usage stays below that baseline, and temporarily increases throughput. section 9.5.2
- Provisioned provides constant throughput up to 1 GiBps and costs $6.00 per MB/s per month. section 9.5.2
- Bursting throughput starts at a 1 MiBps baseline and 100 MiBps burst minimum, then grows with stored data; regional maximums vary. section 9.5.2
- A single client cannot transfer more than 500 MiBps to EFS, regardless of the filesystem's available throughput. section 9.5.2
Provisioned throughput configuration
A CloudFormation resource selects provisioned mode with ThroughputMode: provisioned and sets ProvisionedThroughputInMibps: 1. The configuration also enables encryption and denies insecure transport.
