Cloud computing and AI infrastructure
Amazon Web Services (AWS) provides cloud computing and AI services for startups and enterprises. Its portfolio spans compute, databases, serverless applications and managed AI models. Amazon Bedrock gives developers access to foundation models from multiple providers with governance and security controls, while Bedrock AgentCore supplies infrastructure to deploy and operate AI agents. AWS Lambda lets developers run serverless workloads without managing the underlying infrastructure.
Andy Jassy founded AWS within Amazon in 2006 and led it before becoming Amazon’s CEO in 2021; Matt Garman is the current AWS CEO. Its engineering contributions include Firecracker, introduced in 2018: open source virtualization built on KVM that combines virtual-machine isolation with lightweight microVMs. Designed for container and function workloads, it was already powering Lambda and AWS Fargate at launch, addressing the overhead of isolating serverless workloads.
AWS combines managed services with infrastructure spanning 124 Availability Zones across 39 geographic Regions as of August 2026. Its AI offerings serve an established customer base: Amazon reported hundreds of thousands of Bedrock customers in its Q2 2026 results, alongside an AWS $169 billion annualized revenue run rate. Its hardware work also includes custom silicon for general-purpose computing and AI workloads.

Start with Suman Debnath's demonstration to learn how built-in tools, alternative model providers, and an MCP server fit together in an agent that generates mathematical animations.

Use Justin Muller's talk to examine why plausible answers can hide reasoning errors, how test-case coverage affects evaluation, and why results need analysis by category.

Du’An Lightfoot and Banjo Obayomi lead a hands-on AWS workshop on building autonomous browser agents with Amazon Nova Act, Model Context Protocol servers, and Strands Agents.
Du’An Lightfoot · Banjo ObayomiAI Engineer World's Fair 2025
Suman Debnath introduced an SDK organized around models and tools, while Du’An Lightfoot and Banjo Obayomi demonstrated browser automation with Nova Act and MCP. Mike Chambers followed a simple Python agent through deployment concerns.
Justin Muller framed evaluations as a way to identify actionable failures. Mani Khanuja covered retrieval and PII protection, while Elizabeth Fuentes Leone demonstrated semantic tool selection and booking guardrails using simplified tools she cautioned were not production-ready.
Chintan Agrawal and Daniel Wirjo compared voice activity detection, provider endpointing, and local turn classification. Their demonstration connected these choices to streaming pipelines, interruptions, and latency tradeoffs.
