CloudFront is a content delivery network (CDN) that minimizes latency by caching content on AWS edge locations worldwide. By configuring CloudFront to send real-time logs to Datadog, users can gain deep visibility into the health and performance of their distribution. This setup involves creating a real-time log configuration for an existing CloudFront distribution, specifying the fields included in the logs, and designating a Kinesis Data Stream as the endpoint for sending logs to Datadog. Additionally, users can route logs through Kinesis Data Firehose to Datadog, apply custom tags to their logs, analyze them using Log Explorer, create facets and measures based on log data, and set up log monitors to proactively notify teams of potential problems. This setup enables users to monitor their CloudFront distributions' performance, optimize cache hit ratios, track long-term trends in latency, and improve user experience by tuning parameters like cache size and time to live (TTL).
