AWS Network Synthetic Monitor shows network performance between applications hosted on AWS and destinations on premises. It continuously measures packet loss and latency across hybrid network connections, helping network operators and application developers locate degradation within minutes. AWS manages the monitoring probes, so separate agents are not required on VPCs or on-premises resources. For paths using Direct Connect or Transit Gateway inter-Region peering, a binary network health indicator reports whether degradation is within AWS, using values of 0 or 100. Metrics are published to CloudWatch Metrics for dashboards, thresholds, and alarms. AWS PrivateLink can provide private connectivity to Network Synthetic Monitor resources, while on-premises destinations support IPv4 and IPv6. Each monitored subnet resource can have up to four probes for traffic to four destination IP addresses. Pricing has an hourly fee per monitored AWS resource plus CloudWatch metrics charges, with no upfront costs or long-term commitments. The service does not automatically fail over during an AWS network issue. It is available through API and web interfaces.
Who it is for
It is intended for network operators and application developers who need continuous visibility into hybrid connection performance. Teams using AWS and on-premises destinations can use its measurements and CloudWatch output for diagnosis.
What is good
- Continuously measures packet loss and latency
- AWS manages probes without separate agents
- Binary health indicator helps locate AWS degradation
- CloudWatch dashboards, thresholds, and alarms
- Supports IPv4 and IPv6 destinations
What to know first
- No free plan
- CloudWatch metrics charged separately
- Up to four probes per monitored subnet resource
- No automatic network failover
Verdict
AWS Network Synthetic Monitor focuses on continuous hybrid-network measurements and CloudWatch-based diagnosis. Its probe limit, separate metrics fees, and lack of failover should be considered in network designs.
