Serverless purposes are event-driven, utilizing ephemeral compute capabilities starting from internet APIs, cell backends, and streaming analytics to knowledge processing levels in machine studying (ML) and high-performance purposes. Whereas AWS Lambda features a 512 MB non permanent file system (
/tmp) in your code, that is an ephemeral scratch useful resource not supposed for sturdy storage corresponding to Amazon Elastic File System (Amazon EFS).
Nonetheless, extract, rework, and cargo (ETL) jobs and content material technology workflows corresponding to creating PDF information or media transcoding require quick, scalable native storage to course of massive quantities of information rapidly. Knowledge-intensive purposes require massive quantities of non permanent knowledge particular to the invocation or cached knowledge that may be reused for all invocation in the identical execution atmosphere in a extremely performant method. With the earlier restrict of 512 MB, clients needed to selectively load knowledge from Amazon Easy Storage Service (Amazon S3) and Amazon EFS, or enhance the allotted operate reminiscence and thus enhance their value, simply to deal with massive objects downloaded from Amazon S3. Since clients couldn’t cache bigger knowledge domestically within the Lambda execution atmosphere, each operate invoke needed to learn knowledge in parallel, which made scaling out more durable for patrons.
At present, we’re saying 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 operate will get for studying or writing knowledge, 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’ll be able to 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 Perform
To configure your Lambda operate with bigger ephemeral storage, select the Configuration tab underneath the Basic 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’ll be able to 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’ll be able to replace your required dimension of ephemeral storage utilizing the
$ aws lambda update-function-configuration --function-name PDFGenerator --ephemeral-storage '"Dimension": 10240'
You’ll be able to configure ephemeral storage utilizing Lambda API by way of AWS SDK and AWS CloudFormation. To study extra, see Configuring operate choices within the AWS Documentation.
As a evaluate, AWS Lambda supplies a complete vary of storage choices. To study extra, see an incredible weblog publish, Selecting between AWS Lambda knowledge storage choices in internet 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 appropriate one in your personal purposes.

Now you can configure as much as 10 GB of ephemeral storage per Lambda operate occasion in all Areas the place AWS Lambda is obtainable. With 10 GB container picture help, 10 GB operate reminiscence, and now 10 GB of ephemeral operate storage, you’ll be able to help workloads corresponding to utilizing massive temporal information, knowledge and media processing, machine studying inference, and monetary evaluation.
Assist can be out there 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 operate invokes. To study extra, go to AWS Lambda product and pricing web page and ship suggestions by means of the AWS re:Submit for AWS Lambda or your regular AWS Assist contacts.
