    AWS Deprecates Two Dozen Services (Most of Which You’ve Never Heard Of)

    AWS has deprecated approximately two dozen services in its quarterly cleanup, including 19 services entering maintenance mode, four being sunset, and one reaching end of support. Notable deprecations include Glacier APIs (the S3 storage class remains), S3 Object Lambda, CodeCatalyst, and Snowball Edge. Most deprecated services were commercial failures that never gained significant traction. Glacier's API removal is largely inconsequential since it's now an S3 storage class. CodeCatalyst failed to gain momentum after launch. Snowball Edge customers can continue using existing deployments but shouldn't plan new architectures around it. Many modernization tools are being consolidated into AWS Transform, while Systems Manager components are being wound down in favor of third-party alternatives.

    High Performance Serverless with Rust

    Rust paired with AWS Lambda delivers exceptional performance for serverless applications, with cold starts as low as 11 milliseconds compared to 141ms for Node.js. The presentation covers three key strategies: organizing multi-Lambda projects using Cargo workspaces for code reuse and isolation, leveraging the AWS Lambda runtime and SDK for seamless integration, and implementing infrastructure as code with tools like CDK and Cargo Lambda for automation. Performance benchmarks show Rust functions consume significantly less memory and execute faster, resulting in cost savings of up to 95% compared to other runtimes at scale.

    AWS shows Rust love at re:Invent: 10 times faster than Kotlin, one tenth the latency of Go • DEVCLASS

    AWS now uses Rust by default for data plane projects after finding it significantly faster than Kotlin and Go. Aurora DSQL saw 10x performance improvement when rewritten from Kotlin to Rust. Datadog reduced Lambda cold start times from 700-800ms to 80ms by migrating from Go to Rust, with their observability agent running nearly 3x faster overall. The performance gains stem from Rust avoiding garbage collection overhead, which consumed 30% of execution time in Go code handling many small memory allocations. AWS Lambda now offers general availability for Rust functions using an OS-only runtime.
