AgentCore Runtime V2 holds cold starts at ~2s for images up to 2 GB (vs 30s on the original runtime). It snapshots your environment once and restores it per instance. One field: platformVersion = V2.

S3 Tables now migrates Apache Hive to Iceberg as a managed API call. No pipelines to build, sync while production runs, pay only for data copied.
Weeks of migration work just became an afternoon.

Step Functions workflows are now callable by agents through Bedrock AgentCore Gateway.
The agent decides when to run it. Step Functions runs each step in the order you defined. No improvisation.

AWS updated Developer Associate and Solutions Architect Pro exams to include AI-era cloud work.

Amazon Polly added 14 new voices, 2 in Brazilian Portuguese.
When your user has both hands on a steering wheel, the interface is a voice. Delivery context > feature list.

AWS Continuum validates which code vulnerabilities are exploitable in your environment, ranks them by business impact (not just CVSS), and generates fixes as PRs. Every fix starts human-approved.

AWS released two free courses: one on choosing the right AI compute (Graviton, Trainium, Inferentia, GPUs) and one on EKS efficiency with Auto Mode + Spot. Both under 2 hours, built for engineers who need to ship.

ECS Gateway eliminates per-service ALB setup.
Platform team configures networking once. App team adds one parameter, gets a DNS endpoint. Up to 25 services per ALB, ECS scales automatically.

Lambda now runs a plain HTTP server with no adapter. Point aws lambda-web deploy at Express/Hono/Fastify/Next.js, get back a live URL. Bills CPU time actually used, not wall-clock time. Changes the math for SSR and streaming endpoints.

S3 buckets now provision directly in Vercel. No console switching, no static keys.
OIDC tokens exchange for temporary credentials at runtime. Covers object storage, Iceberg tables, and vector storage.

Prime Day 2026: 2.3 quadrillion ElastiCache requests/day, 192M DynamoDB req/sec, 2.3T Lambda invocations/day.
The prep work: 44K Fault Injection experiments run ahead of time so nothing broke when it mattered.

Lambda Web Functions: deploy a standard HTTP server (Express, Next.js, Hono, Fastify) without rewriting it into an event handler. Multi-concurrent execution, active CPU billing, no adapters.

OpenAI shipped a Decisions API: it returns a bounded choice, not generated text. So it can't hallucinate an option that isn't on the list.
Two ways to wire it into a Strands agent: pick the tool, or pick the model.

DynamoDB: 192 million requests/second during Prime Day 2026. Single-digit millisecond responses.
Lambda: 2.3 trillion invocations/day.
Production scale, not benchmarks.

Amazon Bedrock agents now run OpenAI models with AWS-native execution. Self-hosted or managed runtime, your permissions.
GPT-6.1 Sol: 1/5 the cost of Astra for agentic work. Astra UltraFast: 300 tokens/sec. 🔥

Decision models choose from options instead of generating text. The tradeoff: faster, more capable at a given size, built-in reliability scores.
AWS open-sourced Strands Decider 2B. 2B params, runs locally, answers in milliseconds. Training data include 🙂ift.tt/gsmupYO
S3 Tables now support all Iceberg V3 data types.
Deletion vectors replace positional delete files. Deleting 50k rows from a 2B-row table writes one file instead of thousands. Native variant, nanosecond timestamps, geometry types.
