This file system is being replicated to the US West (Oregon) Region. 200 GB of this data resides in the EFS Standard storage class and 800 GB in the EFS Standard-IA storage class. The example is focused on costs directly related to EFS Replication.Īssume you have an EFS file system in the US East (North Virginia) Region with 1 TB of data. This example reflects a scenario where you are replicating file systems across Regions using EFS Replication. Next, we calculate the access charges for files in EFS Standard-IA: Total EFS Standard-IA storage charge: 326,400 GB-Hours x (1 month / 744 hours) x $0.025/GB-month = $10.97 Next, we convert the storage usage into GB-months and calculate the storage charge: Total EFS Standard storage usage (GB-Hours): 336,000 GB-Hours + 81,600 GB-Hours = 417,600 GB-HoursĨ00 GB of EFS Standard-IA storage for 17 days (GB-Hours): 800 GB x 17 x (24 hours / day) = 326,400 GB-Hours The 800 GB of files read are moved to EFS Standard storage class.įirst, we calculate the pro-rated storage usage:ġ TB of EFS Standard storage for 14 days (GB-Hours): 1,000 GB x 14 days x (24 hours / day) = 336,000 GB-HoursĢ00 GB of EFS Standard storage for 17 days (GB-Hours): 200 GB x 17 days x (24 hours / day) = 81,600 GB-Hours

Once your infrequently accessed files move to EFS Standard-IA, 10 different clients read them all in full once per month. On the 15th day of the month, EFS Lifecycle Management moves 80% of your files to the EFS Standard-IA storage class after 14 days of having not been accessed. At the beginning of a 31-day month, your file system stores 1 TB of files on EFS Standard.
The example assumes that the two EFS Lifecycle policies to move files between EFS Standard and EFS Standard-IA are set.Īssume that your file system is located in the US East (N. The following example reflects a scenario where your file access patterns change over time, and includes each of EFS Standard-IA's pricing dimensions. Total monthly charge = Total monthly storage charge + Total monthly throughput charge =$40.00 + $30.00 = $70.00 Total monthly Provisioned Throughput charge = 5 MB/s-Month x 6.00 = $30.00 Total billable provisioned throughput (MB/s-Month) = 3,720 MB/s-Hours / (31 days/month x 24 hours/day) = 5 MB/s-Month Total billable provisioned throughput (MB/s-Hours) = 7,440 MB/s-Hours – 3,720 MB/s-Hours =3,720 MB/s-Hours Total provisioned throughput (MB/s-Hours) = 10 MB/s x 31 x 24 hours/day = 7,440 MB/s-Hours Total monthly storage charge (see above calculations): $40.00ĭefault throughput (MB/s-Hours) = (74,400 GB-Hours / 20 GB-Hours) * 1 MB/s-Hour = 3,720 MB/s-Hours Provisioned Throughput: 100 GB of data in EFS Standard and 400 GB of data in EFS Standard-IA, with 10 MB/s of Provisioned Throughput Total monthly storage charge (as above): $40.00 Virginia) Region. In the first scenario, you select the default Bursting Throughput mode, and in the second scenario, you configure 10 MB/s of Provisioned Throughput. You would be entitled to a baseline throughput of 5 MB/s in both scenarios because you are storing 100 GB of data on EFS Standard.ĭefault Bursting Throughput: 100 GB of data in EFS Standard and 400 GB of data in EFS Standard-IA, using the default Bursting Throughput mode This example compares two scenarios that assume you store 100 GB on EFS Standard and 400 GB on EFS Standard-IA in the US East (N. California), US West (Oregon), Asia Pacific (Mumbai), Asia Pacific (Osaka), Asia Pacific (Seoul), Asia Pacific (Singapore), Asia Pacific (Sydney), Asia Pacific (Tokyo), Canada (Central), Europe (Frankfurt), Europe (Ireland), Europe (London), Europe (Paris), Europe (Stockholm), South America (São Paulo), and AWS GovCloud Regions.

For same Region replication of file systems in EFS One Zone-Standard and EFS One Zone-IA storage classes across AZs, you pay for data transferred “out” from the source AZ. For replication across Regions, you pay for inter-Region Data Transfer OUT charges to the destination Region. EFS will copy its data to a destination file system in the AWS Region of your choice. In the destination Region, you pay for storage and any applicable read/write data access charges in EFS Infrequent Access storage classes when EFS Lifecycle Management is enabled. Use EFS Replication to replicate your file system to a Region or AZ of your choice without having to manage additional infrastructure or custom processes.
