Part of the AWS re:Invent 2025 Series: Overview | Day 1 | Day 2 | Day 3
8:30AM KEY002: Future of Agentic AI Keynote - Dr. Swami Sivasubramanian, VP AWS
Dr. Swami Sivasubramanian, VP of AI and Data at AWS, presents how Agentic AI is transforming how we work. Key theme: “From Idea to Impact at speed.”
Key Themes
- From Idea to Impact at speed - Central message of the keynote
- What makes an Agent: Model + Code + Tools
- Challenge: Getting agents into production is too hard
- Answer: Model customization for efficiency (latency, scalability, agility)
Announcements
AI/ML & Bedrock
Strands SDK - Open Source AI Agents SDK
An open source SDK for building multi-agent AI systems (announcement):
- Python-based with TypeScript support (preview)
- Model-driven orchestration - Agent behavior driven by LLM capabilities
- Provider agnostic - Bedrock, OpenAI, Anthropic, Gemini, local models (Ollama)
- Multi-agent primitives: Handoffs, swarms, graph workflows
- Edge device support for robotics
- Deployment targets: Lambda, Fargate, EKS, EC2, AgentCore
AgentCore Memory
Episodic functionality that enables agents to remember and learn from previous experiences.
Bedrock Reinforcement Fine Tuning (RFT)
Advanced model customization without deep ML expertise:
- 66% average accuracy gains over base models
- No large labeled datasets required
- Currently supports Amazon Nova 2 Lite (more models coming)
- Reward functions: Rule-based graders, AI judges, built-in templates
- Supports objective (code gen, math) and subjective (instruction following) tasks
Amazon Nova Act - Enhanced
Automate production UI workflows with parallel training capabilities.
SageMaker
SageMaker AI - Serverless Model Customization
Quickly customize models with proprietary data:
- Supported models: Amazon Nova, Llama, Qwen, DeepSeek, GPT-OSS
- Techniques: Supervised fine-tuning, reinforcement learning, direct preference optimization (DPO)
- AI agent-guided workflow (preview) - Uses natural language for data generation, quality analysis, training
- Available regions: Ireland, N. Virginia, Tokyo, Oregon
SageMaker HyperPod Checkpointless Training
Revolutionary approach to training recovery:
- Eliminates checkpoint-based job-level restart
- Reduces training recovery from hours to minutes
- Up to 95% training goodput on large clusters
- Peer-to-peer state transfer from healthy accelerators
- Zero code changes with HyperPod recipes for Llama, GPT OSS
Innovation Talks - Day 2
10:00 AM - INV214: Intelligent Security
Protection at scale from development to production. This session revealed AWS’s internal Active Defense systems—the “secret sauce” behind their managed security services.
AWS Active Defense Systems
Internal security systems powering AWS managed security services:
| System | Function | Scale |
|---|---|---|
| Blackfoot | Network address translation at scale | 312T flows/day |
| MadPot | Sensor system & automated response (honeypot) | 550M malicious activities/day |
| Mithra | Neural network graph model for reputation | 200K malicious domains/day |
| Sonaris | Network traffic behavioral analysis | 4.8B blocked scans/day |
How These Feed AWS Services:
- Automatic Protection: AWS Shield, Amazon S3, Amazon VPC, Route 53 Resolver DNS Firewall
- Managed Rulesets: AWS WAF, AWS Network Firewall
- Findings: Amazon GuardDuty, Amazon Inspector
Key Insight: AWS uses massive-scale internal threat intelligence to automatically protect customer workloads—the “secret sauce” behind their managed security services.
11:30 AM - INV213: Cloud Network Innovation
Speaker: Robert Kennedy - AWS networking innovations shaping the future of cloud infrastructure.
Cross-Region Connectivity for AWS PrivateLink
Share and access VPC endpoint services across different Regions. Service providers can now offer SaaS solutions privately to a global audience from a single Region.
AWS Interconnect - Multicloud (Preview)
Simple, resilient, high-speed private connections to other CSPs:
- First partner: Google Cloud (launch partner)
- Coming 2026: Microsoft Azure
- Eliminates need for third-party connectivity providers
CloudFront Flat Rate Plans
New predictable monthly pricing with no overage charges:
| Plan | Price | Target Audience |
|---|---|---|
| Free | $0/month | Hobbyists, learners, developers |
| Pro | $15/month | Small websites, blogs, applications |
| Business | $200/month | Business applications |
| Premium | $1,000/month | Mission-critical applications |
Included Services: Amazon CloudFront, CloudWatch, WAF, Lambda, Route 53, S3
1:00 PM - INV207: AWS Compute
Speakers: Willem Visser, VP of Amazon EC2 & Barry Cooks, VP of Compute Abstractions
ECS Express Mode
Rapidly launch containerized applications:
- Auto-deploy with automatic domain name generation
- Auto-scales in response to traffic patterns
- Consolidates up to 25 services behind single ALB
- No additional charge - pay only for created resources
- Available via Console, SDK, CLI, CloudFormation, CDK, Terraform
EKS Capabilities
New managed add-ons:
- Managed ArgoCD - GitOps continuous delivery
- ACK Controllers - Manage AWS resources via Kubernetes APIs
- kro (Kube Resource Orchestrator) - Custom Kubernetes APIs for resource composition
EKS Ultra-Scale Clusters
Massive scale Kubernetes clusters for enterprise workloads.
Additional Compute Updates
- GuardDuty Extended Threat Detection - Now supports EC2 and ECS
- Lambda Managed EC2
