Deprecations

Compute and containers

Launch

What it is

What we would do

Lambda Web Functions

Run Express, Hono or similar HTTP servers on Lambda; many requests per environment; billed on requests, active CPU and held memory

Price your Node.js APIs and SSR apps on it before moving them to containers for cost

ECS Gateway

Managed ingress: up to 25 services share an ALB, each with its own hostname and certificate; no extra charge

Adopt for new ECS services; migrate hand-built ALB rule sets when you next touch them

Lambda Durable Execution SDK for Go

Durable functions for Go, GA

Go teams can drop the state table and scheduler they built for long jobs

EC2 T8i in more Regions

Burstable Intel instances, up to 30% better price performance than T3

Move old T2/T3 instances that cannot go to Graviton

AI

Launch

What it is

What we would do

Claude Haiku 5.5 on Bedrock

Around 75% cheaper than Haiku 4.5, with effort controls

Re-run your eval set for classification, routing and extraction; many jobs on larger models can move down

Bedrock Managed Agents powered by OpenAI (preview)

OpenAI models and agent harness run with AWS IAM, CloudTrail and AgentCore Runtime

Pilot only; keep tools behind your own interfaces

Amazon Nova 2.5 Sonic

Speech-to-speech model for real-time voice agents, seven languages, 256K context

Worth a prototype for phone and support use cases

Strands Box

Open-source agent sandbox with fine-grained policy controls

Compare with Lambda MicroVMs if you run untrusted agent code

Data and security

Launch

What it is

What we would do

GuardDuty RDS Protection exfiltration detection

Query analysis on Aurora and RDS PostgreSQL to detect data exfiltration

Turn it on for databases holding customer data

Redshift Iceberg materialized views

Materialized views over Apache Iceberg tables

Use for dashboards over lake data instead of copying it into Redshift

S3 Tables: all Iceberg V3 types

Geometry, geography and nanosecond timestamps

Relevant if you model location or high-precision event time

AWS Continuum

Code vulnerability discovery, validation and fix pull requests (GA); penetration testing in CI/CD (preview)

Start in its propose-only mode; review the fixes it opens

Well-Architected Agent (preview)

AI reviews of live accounts and IaC against Well-Architected, with fixes; needs an AWS Support plan

Run it, then have a person decide which findings matter to the business

CloudWatch log routing and chained parsers

Route log events to groups by condition; parse in sequence

Route debug-level noise to cheaper log classes or shorter retention

Services closing or ending

  • Moved to maintenance on September 29 (closed to new customers): Amazon WorkSpaces Secure Browser and the Chime SDK SIP Media Application.
