AWS unveils a new approach to synthetic monitoring using Amazon Nova Act and Bedrock AgentCore, enhancing user journey validation.
On September 28, 2026, AWS announced a novel method for implementing synthetic monitoring by leveraging Amazon Nova Act in conjunction with Amazon Bedrock AgentCore. This approach aims to provide resilient and managed validation of user journeys, moving beyond traditional, brittle UI scripts.
The solution integrates several AWS services, each fulfilling a distinct role:
- **Amazon Nova Act**: Defines and executes UI workflows through natural-language actions combined with orchestration logic, replacing selector-based scripts with vision and language reasoning.
- **Amazon Bedrock AgentCore Runtime**: Offers serverless execution with session isolation and stable invocation endpoints, hosting the monitoring agent without the need for server or container management.
- **AgentCore Browser Tool**: Provides a secure, isolated remote browser environment for each test run, eliminating the overhead associated with operating browser farms.
- **Amazon EventBridge Scheduler and Amazon SNS**: Handle scheduling and alerting, triggering tests on a defined cadence and delivering failure notifications to subscribed endpoints.
The architecture follows a structured flow:
1. Scheduling : Amazon EventBridge Scheduler triggers synthetic monitoring runs at specified intervals, ranging from every five minutes to hourly, depending on workflow criticality.
2. Invocation : Each scheduled invocation calls `InvokeAgentRuntime` directly through the universal target capability of Amazon EventBridge Scheduler.
3. Execution : The agent executes within AgentCore Runtime, invoking Amazon Nova Act to drive the UI workflow using natural-language actions inside an AgentCore Browser session.
4. Notification : If the journey fails at any step, the agent publishes a notification through Amazon SNS, routing failures immediately to subscribed endpoints such as email, chat integrations, or incident response tools.
This architecture offers fully managed synthetic monitoring, allowing teams to avoid maintaining fragile scripts or browser infrastructure. By focusing on high-value customer journeys and validating meaningful outcomes, organizations can reduce alert fatigue and enhance the reliability of their monitoring processes.
AWS provides comprehensive guidance on setting up this solution, including prerequisites, journey definition, agent deployment, and scheduling infrastructure. The implementation emphasizes the importance of defining critical customer journeys, deploying agents effectively, and avoiding over-monitoring to maintain the efficacy of the monitoring system.
