Yes, Amazon Route 53 can monitor non-AWS resources using health checks. Route 53 health checks are not limited to AWS resources; they can be used to monitor the availability and performance of any resource with a publicly accessible endpoint (e.g., websites, APIs, servers) hosted outside AWS.
How Route 53 Monitors Non-AWS Resources :
Route 53 health checks send requests to the specified endpoint (an IP address, DNS name, or URL) at regular intervals. Based on the response, the health check determines if the endpoint is healthy or unhealthy.
Supported Types of Endpoints for Non-AWS Resources :
-
HTTP/HTTPS Endpoints:
- Checks the health of a web server or API by sending HTTP or HTTPS requests.
- You can configure:
- Path to monitor (e.g.,
/health).
- Port (e.g., 80 for HTTP, 443 for HTTPS).
- Expected response codes (e.g.,
200 for success).
-
TCP Endpoints:
- Checks the health of a TCP-based service (e.g., a custom application) by verifying that the server accepts connections on a specific port.
-
Domains or IP Addresses:
- Health checks can monitor DNS-resolvable domains or direct IP addresses.
Features of Route 53 Health Checks for Non-AWS Resources :
-
Global Monitoring:
- Route 53 health checks originate from multiple locations worldwide, ensuring global availability testing.
-
Failover and Routing:
- If a health check determines that a non-AWS resource is unhealthy, Route 53 can automatically route traffic to a backup resource.
-
Threshold Configuration:
- You can define the number of consecutive failed health check responses required to mark a resource as unhealthy.
-
Latency-Based Checks:
- In addition to availability, health checks can measure response latency to ensure performance metrics are met.
-
Alarm Integration:
- Health checks can be integrated with Amazon CloudWatch, enabling you to set up alarms and notifications for unhealthy endpoints.
-
Custom Health Checks:
- Route 53 allows you to specify custom responses or codes for validating endpoint health.
