Speed up page load times and save on costs by compressing dynamic content

With dynamic compression, Cloud CDN automatically reduces the size of responses that are transferred from the edge to a client, even if they were not compressed by the origin server. In a sample of popular CSS and Javascript files, we saw that dynamic compression reduced response sizes between 60 to 80%.

This is a win-win for both your web service and its end users. With dynamic compression, you get:

1. Faster page load: By reducing the size of content like CSS and Javascript resources, you can reduce time to first contentful paint and page loads overall.
2. Cost management: Web services that serve a large amount of compressible content can significantly reduce their cache egress costs by enabling dynamic compression.

Cloud CDN supports gzip and Brotli compression for web resources like HTML, CSS, Javascript, JSON, HLS playlists, and DASH manifests.Get started with dynamic compression in GA today.

Customize cache keys to improve CDN performance

When a request comes to Cloud CDN’s edge, it gets mapped to a cache key and compared against entries in the cache. By default, Cloud CDN uses the protocol, host, path, and query string from the URI to define these cache keys.

Using Cloud CDN’s new custom cache keys, you can better control caching behavior in order to improve cache hit rates and origin offload. We now support using named headers and cookies. If your web service implements A/B testing or canarying, using named cookies to define cache keys may be especially useful.

Using Cloud CDN’s new allowlist for URI parameters for Cloud Storage, you can also implement cache busting. This is a strategy that enables your end users to find the latest version of a cached resource even if an older version is active in the cache. By adding a query parameter that specifies versioning and adding it to the allowlist, you can avoid needing to explicitly invalidate the older cached version. Allowlists are now available for backend buckets, in addition to existing support for backend services.
