In an earlier post, we discussed the meaning of cache hit ratio (CHR) and analyzed what the metric is and isn’t telling us, showing why we really need two different CHR metrics (CHRedge and CHRglobal) to fully understand how a CDN is serving your clients. In this post, we’ll analyze CHRedge by way of a discussion about performance measurement via testing.

One of the most common metrics for evaluating CDN performance is cache hit ratio (CHR). CDN customers have used it for years as a primary indicator of how well a CDN is serving their users and handling their traffic, but there’s more to it than meets the eye. Our VP of Technology digs into what CHR actually measures and how we may need new ways of calculating and evaluating it.

Our CDN can cache more content than traditional solutions (static as well as rapidly changing, “event-driven” content), offloading traffic that would otherwise go to origin, allowing our customers to save on infrastructure costs. But just how big are these savings? To help answer this question at a glance, we recently launched our savings calculator, which offers quick insight into the savings you can expect as a result of improved cache hit ratios.

In this post, Tyler McMullen will explore “the future of the edge,” or the next logical step in how we streamline online experiences. In order to keep up with the direction things are headed, we need to combine logic and data at the edge. Logic without data, without state, is insufficient.

Using a CDN for beacon termination at the edge has gotten a lot of attention, in part because edge termination for beacons is cool; but it’s mostly because beaconing applications are becoming more popular and they involve a lot of components, deployed at scale, to accommodate proper data collection.

Last Sunday over 111.9 million viewers tuned in for the Super Bowl. As a CDN, we’re in a unique position — we help companies handle the impact of successful Super Bowl ads, and monitor the results in real time. We thought it might be interesting to share some of the traffic patterns we noticed during the big game.
