In other words, the data is not looking at your actual web traffic but a simulated environment that gives you an approximate view of traffic when certain conditions are in place.

I propose four key ingredients: Definition: What is "performance" beyond page speed? Herein lies the source of our collective anxiety about front-end architectures: traversing networks is always fraught, but the costs to deliver client-side logic to cushion users from variable network latency remain stubbornly high.

Cue server-timing headers Historically, when looking at page speed, we've had the tendency to ignore TTFB when trying to optimize the user experience. The use of server-timing headers by content delivery networks closes a big gap. Definitely worth a read! I mean, why wouldn't we? But what happens when it doesn't?

There are many ways of measuring your Core Web Vitals , but the definitive way — even if it’s not the best way, as we’ll see soon — is in Google Search Console (GSC).

Common components of DR and HA architectures By definition, there are differences between high availability (HA) and disaster recovery (DR). Load balancing: Load balancers distribute traffic evenly across multiple servers or data centers. In DR, load balancers route traffic to the secondary data center when a failover occurs.

Thanks to progress in networks and browsers (but not devices), a more generous global budget cap has emerged for sites constructed the "modern" way: ~100KiB of HTML/CSS/fonts and ~300-350KiB of JS (compressed) is the new rule-of-thumb limit for at least the next year or two.

Both Xen and KVM have had many performance and security improvements, and workloads can now be tuned to run at almost bare metal speeds (say, a 3% loss or less). At my employer we sometimes use SR-IOV for direct network interface access, and NVMe for direct disk access. Outside of EC2, many other providers are deploying on KVM.
