In technical terms, network-level firewalls regulate access by blocking or permitting traffic based on predefined rules. ‍At its core, WAF operates by adhering to a rulebook—a comprehensive list of conditions that dictate how to handle incoming web traffic. You'll have logs and analytics scattered across different CDNs.

We took a hybrid head-based sampling approach that allows for recording 100% of traces for a specific and configurable set of requests, while continuing to randomly sample traffic per the policy set at ingestion point. This allowed us to increase total storage capacity without adding a new Cassandra node to the existing cluster.

To show that I can criticize my own work as well, here I show that sustained memory bandwidth (using an approximation to the STREAM Benchmark ) is also inadequate as a single figure of metric. (It Here I assumed a particular analytical function for the amount of memory traffic as a function of cache size to scale the bandwidth time.

Edgar captures 100% of interesting traces , as opposed to sampling a small fixed percentage of traffic. In one request hitting just ten services, there might be ten different analytics dashboards and ten different log stores. The downside is that we have so many dashboards. Is this an anomaly or are we dealing with a pattern?

Using a global ASP as a benchmark can further mislead thanks to the distorting effect of ultra-high-end prices rising while shipment volumes stagnate. CrUX data collection and first-party RUM analytics of these metrics require live traffic, meaning results can be predicted but only verified once deployed. A 2021 Global Baseline.
