The interconnections between nodes and the rest of the system makes it possible to communicate and share data efficiently. This also includes latency, or the time it takes for data or a request to get through a network. Reliability. Another key benefit of distributed systems is reliability. Fault Tolerance.

As defined by the Google SRE initiative, the four golden signals of monitoring include the following metrics: Latency. Latency is the amount of time, or delay, a service takes to respond to a request. Get started for free with the Dotcom-Monitor 30-day trial or schedule a demo with one of our performance engineers.

Using CDN for the whole website, you can offload most of the website traffic to your CDN which will handle not only large traffic spikes but also reduce the latency of content delivery. They often get blindsided by vendor’s pitch and end-up making decision based on some fancy demos (see my post from 2014 on Adobe AEM ).

Estimated Input Latency tells us if we are hitting that threshold, and ideally, it should be below 50ms. Designed for the modern web, it responds to actual congestion, rather than packet loss like TCP does, it is significantly faster , with higher throughput and lower latency — and the algorithm works differently.

. - **eBPF**: tracing features completed in 2016, this provides efficient programmatic tracing to existing kernel frameworks. Here's some output from my zfsdist tool, in bcc/BPF, which measures ZFS latency as a histogram on Linux: # zfsdist. Tracing ZFS operation latency. Hit Ctrl-C to end. ^C

Estimated Input Latency tells us if we are hitting that threshold, and ideally, it should be below 50ms. In exchange, your team gains maintainability and developer efficiency, of course. A sample output by imaging-heap , a command line tool that measure the efficiency across viewport sizes and device pixel ratios.
