AWS Summit New York City 2026: AgentCore Seven Services, Amazon Quick, Kiro Pro Max, S3 Vectors — Builder Guide

AWS Summit New York City 2026 ran June 17 at the Javits Center. VP of Agentic AI Swami Sivasubramanian led the keynote at 11 AM ET, with AWS at a $142 billion annualized run rate and agentic AI as the organizing theme for virtually every service announcement.

The throughline: AWS is no longer treating agents as an experimental feature. The entire platform — storage, compute, identity, observability — is being reoriented around them.

Here is what builders need to know.

AgentCore: Now a Seven-Service Production Infrastructure Suite

When AgentCore launched in April 2026, it was a runtime with microVM isolation and a managed harness. Good start; incomplete picture.

The summit clarified the full architecture. AgentCore is seven services that together form an infrastructure stack for running agents in enterprise production:

Service	What it handles
AgentCore Runtime	Per-session microVM isolation, 8-hour sessions, managed agent loop
AgentCore Memory	Cross-session and cross-agent persistent memory stores
AgentCore Identity	OAuth 2.0 + OIDC scoped to agent sessions; credential rotation
AgentCore Code Interpreter	Sandboxed Python execution inside the agent session boundary
AgentCore Browser Tool	Managed headless browser for web-based agent tasks
AgentCore Gateway	MCP-compatible tool routing; connects agents to enterprise systems
AgentCore Observability	Trace IDs, latency, tool call logs; integrates with CloudWatch and OpenTelemetry

This matters because the common failure mode for production agents is not the LLM — it is the surrounding infrastructure: leaked credentials, state bleed between sessions, no audit trail. AgentCore’s seven-service model addresses each of these explicitly.

For builders: If you are on AWS and building production agents, AgentCore is now the default answer for “where do I run this.” It works with any framework (CrewAI, LangGraph, LlamaIndex, Strands, custom) and any Bedrock-compatible model.

Amazon Quick: Q Business Replaced by a Five-Module Agentic System

Amazon Quick launched April 28, 2026, as a full replacement for Amazon Q Business. The summit gave it its biggest public stage yet.

Where Q Business offered reactive chat against organizational data, Quick is a five-module architecture designed for autonomous workflow execution:

Spaces — collaborative workspaces where teams and agents share context
Chat Agents — autonomous agents that execute cross-app workflows (not just answer questions)
Flows — natural-language automation builder for connecting enterprise tools
Research — deep search across internal and external data simultaneously
Automations — drag-and-drop workflow scheduler with built-in monitoring

Quick ships with 100+ integrations: Microsoft 365, Google Workspace, Slack, Teams, Salesforce, Jira, ServiceNow. Desktop app (macOS and Windows) plus Chrome, Edge, and Firefox extensions.

For builders assessing Quick vs. building custom: Quick is the right call when the goal is cross-app workflow automation for business users — HR, finance, operations. It is not a developer platform. If you need custom agent logic, tool calling, or tight control over model behavior, AgentCore is the answer, not Quick. They are complementary, not competing.

Kiro Pro Max: $100/Month Tier for Serious Daily Use

Kiro is AWS’s spec-driven agentic IDE — it generates requirements.md, design.md, and tasks.md documents before writing a line of code. That spec-first approach means it works better than most tools for large, multi-file features but adds friction for quick one-off changes.

Kiro Pro Max is a new pricing tier at $100/month, slotting between Pro+ ($40/mo) and Power ($200/mo). It is aimed at developers who consistently exceed their Pro+ credit allocation without needing the full Power tier.

Under the hood, Kiro uses Claude Sonnet for reasoning-heavy spec generation and Amazon Nova for high-throughput code generation, switching models based on task type.

The decision:

You want	Plan
Occasional use, learning Kiro	Free
Daily use, single project	Pro+ ($40/mo)
Daily use, multiple projects, frequent spec runs	Pro Max ($100/mo)
Full-time agent-driven development, large teams	Power ($200/mo)

S3 Vectors: Native Vector Storage at 90% Lower Cost

S3 Vectors is a new S3 capability that adds native vector storage and querying directly in object storage — no separate vector database required for basic retrieval use cases.

Key numbers:

90% cost reduction compared to conventional vector database approaches for cold or archival retrieval workloads
Supports similarity search, metadata filtering, and batch writes natively
Scales with S3’s existing durability and access control model

When S3 Vectors makes sense: High-volume, lower-latency-tolerance retrieval (document archives, batch embedding pipelines, long-term memory for agents). For real-time RAG with sub-50ms requirements, purpose-built vector databases (Pinecone, Weaviate, pgvector) still have the advantage.

When it does not: If you need millisecond retrieval with high concurrency for interactive applications, S3 Vectors is not the right choice today.

Nova Act: Browser Automation with 90%+ Enterprise Task Completion

Nova Act is Amazon’s browser automation agent, trained for enterprise web tasks: form filling, portal navigation, multi-step approvals, data extraction from web applications.

The claim is 90%+ task completion on enterprise use cases — notably higher than general-purpose browser automation like Playwright + LLM or Puppeteer-based approaches, which often fall apart on dynamic authentication flows and multi-page state.

Nova Act is built into AgentCore as an optional tool via AgentCore Browser Tool, so it inherits full session isolation and credential management.

Use cases: Agent-driven access to vendor portals, legacy intranet tools, SaaS applications without APIs, compliance workflows that live in web-only interfaces.

AWS AI Agents Marketplace

New: a dedicated AI Agents and Tools category in AWS Marketplace. It allows customers to discover, purchase, deploy, and manage pre-built AI agents and MCP-compatible tools from third-party providers — all within the AWS billing and IAM framework.

For ISVs and tool builders, this is a new distribution channel with AWS’s enterprise purchasing infrastructure already attached.

AWS FinOps Agent (Preview)

Announced in the June 15 weekly roundup and reinforced at the summit: AWS FinOps Agent is in preview. It can:

Answer cost questions across services and time windows
Surface rightsizing recommendations via Cost Optimization Hub and Compute Optimizer
Investigate cost anomalies automatically
Open Jira tickets based on recommendations
Post findings to Slack on a defined schedule

This is a meaningful development for teams with growing AWS bills and limited FinOps bandwidth. The scheduled anomaly investigation in particular — running at set intervals and posting to Slack before anyone asks — addresses a common operations gap.

What Today’s Summit Means for Builders

The short version: AWS has shipped the infrastructure layer for production agents. The April preview filled in half the picture; today filled in the rest.

You’re building	The AWS path
Production agent with isolated sessions + audit trail	AgentCore (seven services)
Cross-app workflow automation for business teams	Amazon Quick
Spec-driven development with agentic IDE	Kiro (Pro or Pro Max)
RAG pipeline with large embedding corpus, cost-sensitive	S3 Vectors
Agents that interact with web portals	Nova Act via AgentCore Browser Tool
Cost optimization with autonomous monitoring	AWS FinOps Agent (preview)

The pattern here is not subtle: AWS is betting that agentic AI becomes the interface through which enterprises interact with all of their cloud infrastructure — not just AI services, but storage, security, observability, and operations. Today’s summit is the most coherent statement of that bet yet.
