Monitoring, Logging, Analysis, Remediation, and Performance Optimization

A company must monitor the availability of its website for end users. The company requires a solution that sends an Amazon Simple Notification Service (Amazon SNS) notification when the website's uptime falls below 99%. The monitoring must deliver an accurate representation of the website user experience.

Which solution meets these requirements?

Explanation

CloudWatch Synthetics heartbeat canaries load a specified website URL on a schedule, simulating customer access and thereby measuring availability from the end-user perspective. Canaries publish the SuccessPercent metric, which is the percentage of successful canary runs; a CloudWatch alarm can trigger an Amazon SNS notification when that metric falls below 99%.
