Introduction
Global, distributed AWS architectures are the backbone for customers seeking high availability, resilience, and regulatory compliance. Workloads are commonly deployed across multiple AWS Regions and Availability Zones (AZs), often using AWS PrivateLink to connect services securely and privately across Amazon Virtual Private Cloud (Amazon VPC) networks. This approach enhances security and separation while requiring additional monitoring capabilities to maintain comprehensive observability.
To detect subtle, path-specific “grey failures” in your distributed architecture, you need Amazon CloudWatch Network Synthetic Monitor, which runs end-to-end probes against your actual VPC paths, PrivateLink endpoints, and service ports. You may need this level of targeted monitoring to detect packet loss or latency on a critical path.
To complement Network Synthetic Monitor’s path-specific testing, AWS Network Manager Infrastructure Performance…
