Here’s a quick look to show how AWS Fargate support for SOCI works: At launch, this new capability is available for Amazon Elastic Container Service (Amazon ECS) applications running on AWS Fargate. ![]() Today, I’m excited to share that AWS Fargate now supports Seekable OCI (SOCI), which helps applications deploy and scale out faster by enabling containers to start without waiting to download the entire container image. As part of that effort, we open sourced SOCI Snapshotter, a snapshotter plugin that enables lazy loading with SOCI in containerd. Last year, we introduced Seekable OCI (SOCI), a technology open sourced by Amazon Web Services (AWS) that enables container runtimes to implement lazy loading the container image to start applications faster without modifying the container images. This approach downloads data from the container registry in parallel with the application startup, such as stargz-snapshotter, a project that aims to improve the overall container start time. One solution to this problem is lazy loading (also known as asynchronous loading) container images. This may introduce a non-trivial latency, as the entire image must be downloaded and unpacked before the applications can be started. Starting and scaling out containerized applications requires downloading container images from a remote container registry. This issue can have a negative impact on the customer experience, for example when a website needs to scale out to serve additional traffic.Ī research paper shows that container image downloads account for 76 percent of container startup time, but on average only 6.4 percent of the data is needed for the container to start doing useful work. One of the main issues with scaling containerized applications is the long startup time, especially during scale up when newer instances need to be added. ![]() While developing with containers is becoming an increasingly popular way for deploying and scaling applications, there are still areas where improvements can be made.
