Instead of downloading the full image upfront, Lambda streams only the files needed at each startup stage, cutting container startup times by up to 70%. To use it, create a SOCI index for your image, push it to Amazon ECR, and set the function's image URI to the SOCI-indexed tag. Lambda then auto-detects the index and enables lazy loading with no extra configuration. The feature works in all AWS commercial regions where Lambda Managed Instances is available. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How do I enable Seekable OCI (SOCI) lazy loading for my AWS Lambda container image? Create a SOCI index, which acts as a table of contents for your image layers, and push it to Amazon ECR. When creating or updating a Lambda function on Lambda Managed Instances, set the image URI to the SOCI-indexed tag (e.g. my-function:v1-soci) and publish a function version. Lambda automatically detects the index and enables lazy loading with no extra configuration. _Teams speeding up Lambda cold starts can track rollout details like this on daily.dev._ ### How much faster does Lambda container startup get with SOCI lazy loading on Lambda Managed Instances? Container startup times can be reduced by up to 70%. Instead of downloading an entire multi-gigabyte container image before a function can run, Lambda streams only the files needed at each stage of execution environment startup, which removes the multi-minute delay that large images previously caused when provisioning new environments. _Developers scaling container-based Lambda workloads can follow updates like this on daily.dev._ ## Similar posts on daily.dev - [Docker lazy loading at Grab: Accelerating container startup times](https://daily.dev/posts/docker-lazy-loading-at-grab-accelerating-container-startup-times-nl6artdyl) · Grab Tech Blog · 83 upvotes · 4 comments - [AWS Lambda now supports SnapStart for container image functions](https://daily.dev/posts/aws-lambda-now-supports-snapstart-for-container-image-functions-ssafmfewu) · AWS · 0 upvotes · 0 comments - [AWS Lambda announces self-managed code storage](https://daily.dev/posts/aws-lambda-announces-self-managed-code-storage-jb2c0qruw) · AWS · 0 upvotes · 0 comments - [AWS Launches Amazon S3 Files: Bridging Object and File Storage](https://daily.dev/posts/aws-launches-amazon-s3-files-bridging-object-and-file-storage-eaqooxiev) · C\# Corner · 0 upvotes · 0 comments --- Tags: [#aws](https://daily.dev/tags/aws), [#containers](https://daily.dev/tags/containers), [#serverless](https://daily.dev/tags/serverless), [#aws-lambda](https://daily.dev/tags/aws-lambda) [View this post on daily.dev](https://daily.dev/posts/aws-lambda-supports-seekable-oci-soci-lazy-loading-for-lambda-managed-instances-kxsyvaluo) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"AWS Lambda supports Seekable OCI (SOCI) lazy loading for Lambda Managed Instances","url":"https://daily.dev/posts/aws-lambda-supports-seekable-oci-soci-lazy-loading-for-lambda-managed-instances-kxsyvaluo","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/aws-lambda-supports-seekable-oci-soci-lazy-loading-for-lambda-managed-instances-kxsyvaluo"},"datePublished":"2026-10-28T20:04:45.387Z","dateModified":"2026-10-28T21:34:23.466Z","description":"AWS Lambda now supports Seekable OCI (SOCI) lazy loading for container images on Lambda Managed Instances.
