AWS Lambda Now Helps As much as 10 GB Ephemeral Storage

Serverless functions are event-driven, utilizing ephemeral compute capabilities starting from net APIs, cell backends, and streaming analytics to information processing phases in machine studying (ML) and high-performance functions. Whereas AWS Lambda features a 512 MB momentary file system (/tmp) in your code, that is an ephemeral scratch useful resource not meant for sturdy storage corresponding to Amazon Elastic File System (Amazon EFS).

Nonetheless, extract, rework, and cargo (ETL) jobs and content material era workflows corresponding to creating PDF recordsdata or media transcoding require quick, scalable native storage to course of giant quantities of information shortly. Information-intensive functions require giant quantities of momentary information particular to the invocation or cached information that may be reused for all invocation in the identical execution surroundings in a extremely performant method. With the earlier restrict of 512 MB, prospects needed to selectively load information from Amazon Easy Storage Service (Amazon S3) and Amazon EFS, or enhance the allotted perform reminiscence and thus enhance their price, simply to deal with giant objects downloaded from Amazon S3. Since prospects couldn’t cache bigger information domestically within the Lambda execution surroundings, each perform invoke needed to learn information in parallel, which made scaling out more durable for purchasers.

As we speak, we’re asserting that AWS Lambda now means that you can configure ephemeral storage (/tmp) between 512 MB and 10,240 MB. Now you can management the quantity of ephemeral storage a perform will get for studying or writing information, permitting you to make use of AWS Lambda for ETL jobs, ML inference, or different data-intensive workloads.

With elevated AWS Lambda ephemeral storage, you get entry to a safe, low-latency ephemeral file system as much as 10 GB. You may proceed to make use of as much as 512 MB at no cost and are charged for the quantity of storage you configure over the free restrict during invokes.

Setting Bigger Ephemeral Storage for Your Lambda Operate
To configure your Lambda perform with bigger ephemeral storage, select the Configuration tab below the Common Configuration part within the AWS Lambda Console. You will notice a brand new configuration for Ephemeral storage setting at 512MB by default.

Once you click on the Edit button, you possibly can configure the ephemeral storage from 512 MB to 10,240 MB in 1 MB increments in your Lambda capabilities.

With AWS Command Line Interface (AWS CLI), you possibly can replace your required measurement of ephemeral storage utilizing theupdate-function-configuration command.

$ aws lambda update-function-configuration --function-name PDFGenerator 
              --ephemeral-storage '{"Measurement": 10240}'

You may configure ephemeral storage utilizing Lambda API by way of AWS SDK and AWS CloudFormation. To be taught extra, see Configuring perform choices within the AWS Documentation.

As a evaluate, AWS Lambda supplies a complete vary of storage choices. To be taught extra, see an amazing weblog put up, Selecting between AWS Lambda information storage choices in net apps, written by my colleague James Beswick. I wish to quote the desk to point out the variations between these choices and customary use-cases that can assist you select the best one in your personal functions.

Accessible Now
Now you can configure as much as 10 GB of ephemeral storage per Lambda perform occasion in all Areas the place AWS Lambda is offered. With 10 GB container picture assist, 10 GB perform reminiscence, and now 10 GB of ephemeral perform storage, you possibly can assist workloads corresponding to utilizing giant temporal recordsdata, information and media processing, machine studying inference, and monetary evaluation.

Help can also be accessible by means of many AWS Lambda Companions corresponding to Datadog, HashiCorp (Terraform), Lumigo, Thundra, Slalom, and Contino.

For this characteristic, you’re charged for the storage you configure over the 512 MB free restrict during your perform invokes. To be taught extra, go to AWS Lambda product and pricing web page and ship suggestions by means of the AWS re:Put up for AWS Lambda or your traditional AWS Help contacts.


Replace. To be taught widespread use instances and deploy an instance utility to resize a video file in Lambda’s ephemeral storage, go to Utilizing bigger ephemeral storage for AWS Lambda in AWS Compute Weblog.
