In this session, we discuss the technologies used to run a global streaming company, growing at scale, billions of metrics, benefits of chaos in production, and how culture affects your velocity and uptime. Netflix runs dozens of stateful services on AWS under strict sub-millisecond tail-latency requirements, which brings unique challenges.

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. Modern network performance and availability.

They can also bolster uptime and limit latency issues or potential downtimes. Establishing clear service-level agreements is key as they outline specific responsibilities and performance benchmarks expected from cloud service providers during disaster recovery scenarios.

This is a complex topic, but to borrow from a recent post , web performance expands access to information and services by reducing latency and variance across interactions in a session, with a particular focus on the tail of the distribution (P75+). Consistent performance matters just as much as low average latency.

Site performance is potentially the most important metric. Google’s industry benchmarks from 2018 also provide a striking breakdown of how each second of loading affects bounce rates. Having a slow site might leave you on page 452 of search results, regardless of any other metric. Source: Google /SOASTA Research, 2018.

We constrain ourselves to a real-world baseline device + network configuration to measure progress. Budgets are scaled to a benchmark network & device. This helps support executive sponsors who then have meaningful metrics to point to in justifying the investments being made. Partner meetings are illuminating.

Before you begin tuning your website or application, you must first figure out which metrics matter most to your users and establish some achievable benchmarks. Quantitative performance testing looks at metrics like response time while qualitative testing is concerned with scalability, stability, and interoperability.

As an engineer on a browser team, I'm privy to the blow-by-blow of various performance projects, benchmark fire drills, and the ways performance marketing (deeply) impacts engineering priorities. With each team, benchmarks lost are understood as bugs. Another window into this question is provided by the Web Confluence Metrics project.

Metrics communicate what’s happening on a macro scale, traces illustrate the ecosystem of an isolated request, and the logs provide a detail-rich snapshot into what happened within a service. starting and finishing a method).

Many high-end disk subsystems provide high-speed cache facilities to reduce the latency of read and write operations. Microsoft strongly recommends maintaining the default recovery interval to ensure optimal recovery metrics and to function cleanly within the current cluster resource constraints.
