AWS Announces Synthetic Monitoring Using Amazon Nova Act

AWS has announced the implementation of synthetic monitoring using Amazon Nova Act, a service designed to continuously validate critical workflows such as logins, purchases, and form submissions. This approach allows teams to detect performance degradation or UI interaction issues before customers experience them, ensuring that product search, pricing, inventory, and checkout processes work correctly.

Synthetic monitoring runs on a defined schedule, ranging from every 5 minutes to hourly, depending on the criticality of the workflow. Each scheduled invocation calls InvokeAgentRuntime directly through the universal target capability of Amazon EventBridge Scheduler. The agent executes within AgentCore Runtime, invoking Amazon Nova Act to drive the UI workflow using natural-language actions inside an AgentCore Browser session. If a journey fails at any step, the agent publishes a notification through Amazon SNS, which routes immediately to subscribed endpoints such as email, chat integrations, and incident response tooling.

This architecture provides fully managed synthetic monitoring, eliminating the need for teams to maintain brittle scripts or browser infrastructure. The implementation involves setting up prerequisites, defining journeys, deploying agents, and scheduling infrastructure. The complete working implementation is available in the sample repository: github.com/aws-samples/sample-nova-act-synthetic-monitoring.
