In addition to reducing latency, these edge locations also bring the full suite of benefits provided by Amazon CloudFront, such as Level Encryption, and Amazon S3 Transfer Acceleration, as well as seamless integration with other AWS services like AWS Certificate Manager (ACM), AWS Shield, AWS WAF, AWS Simple Storage Service (S3), and Amazon Elastic Compute Cloud (EC2). The addition of these two locations brings CloudFront’s global network to 410+ points of presence in 90+ cities, across 48 countries. Viewers served by these new edge locations can expect up to a 30% improvement in first-byte latency. For more information, refer to the CloudFront Developer Guide and API documentation.ĭetails: Amazon CloudFront announces its first edge locations in Hanoi and Ho Chi Minh City, Vietnam. In addition to the real-time logs, you can also configure your CloudFront origin request policies to forward the CloudFront-Viewer-ASN header to your origin servers. These new fields can be enabled via the CloudFront Console, SDK, and CLI. ASN is a unique number that identifies the network, such as an internet service provider (ISP) network, that provides the viewer IP address. The Origin last-byte latency indicates the time taken in seconds by the origin server to respond back with the last byte of the response. The Origin first-byte latency provides the time taken in seconds by the origin server to respond back with the first byte of the response.
With the three new data fields, customers can get more granular insights on CloudFront performance while analyzing real-time logs, or in the dashboards created using the logs. CloudFront real-time logs contain detailed information about requests delivered by CloudFront such as the HTTP status codes of the response, or whether the response was cached.
Amazon CloudFront adds fields for origin latency and ASN in real-time logs for more granular insightsĭetails: Amazon CloudFront now offers three additional data fields in CloudFront real-time logs: Origin first-byte latency, Origin last-byte latency, and autonomous system number (ASN).
