AWS Architecture Blog

Regression testing must catch behavior changes before they reach production, yet synthetic tests miss real-world edge cases. This post walks through a modular framework, built on AWS, that replays a sample of production traffic against new code and automatically gates deployments on the fraction of results that match production.

Building multimodal AI/ML pipelines on Amazon EC2 means scaling distributed compute, controlling costs across stages, and keeping up with new models and hardware. This post shows how the Ray-powered Anyscale application on AWS helps you deploy Ray across three compute options and scale from prototype to production without code changes.

This post lays out a five-layer reference architecture for governed, observable enterprise AI agents on AWS: an API gateway, a five-phase agent runtime, a knowledge and state tier, platform services, and a cross-cutting trust and control framework. Each layer maps to managed AWS services, with the design patterns worth copying and the mistakes to avoid.

Zillow sends more than 100 million personalized notifications a day, each as a short-lived AWS Step Functions Express workflow. See how the Comms Experience team replaced more than 10 campaign generators with one configuration-driven orchestration platform and a library of reusable content modules.

Application teams in regulated enterprises can execute self-service regional failover with Amazon Application Recovery Controller (ARC) Region Switch, even behind centrally managed ingress proxy fleets. Learn how Transit Gateway peering, Route 53 Private Hosted Zones, and VPC Lattice preserve security controls while removing cross-team coordination during DR.

Learn how Novus Hi-Tech, with the AWS Prototyping and AI Customer Engineering (PACE) team, built FleetGPT, an agentic AI solution on Amazon Bedrock that turns fleet IoT data into real-time safety interventions through natural language querying, automated investigation, and AI-powered driver voice calls, cutting road-behavior violations by 46% and drowsiness alerts by 55%.

DeepL runs a multi-Region hybrid network across multiple AWS Regions and AWS Direct Connect locations. See how DeepL drains a single Direct Connect link for planned maintenance without packet loss or cross-Region rerouting, using AWS Cloud WAN and an on-premises AS_PATH prepend so every other Region keeps its closest-exit routing.

See how Cognizant and AWS Professional Services transformed the OrderServ food-ordering platform into a multi-tenant SaaS offering on shared Amazon ECS, cutting compute costs up to 64%, reducing scaling time from minutes to seconds, and lowering authentication costs by 80%.

Learn how TUI, the world’s leading tourism group, built an AI-powered threat modeling system on Amazon Bedrock and Amazon Bedrock AgentCore to scale security assessments across more than 100 product teams, cutting threat modeling time by up to 70% while applying security standards consistently.

This final post turns the DR framework into a repeatable engagement: a five-step sequence from kickoff and gap assessment through progressive validation to an updated recovery commitment, with a real before-and-after example and ways to compress the timeline from months to weeks. Part 3 of a three-part series.
