A Cassandra database cluster had switched to Ubuntu and noticed write latency increased by over 30%. top(1) showed that only the Cassandra database was consuming CPU. Colleagues/Internet I love using [Linux performance tools]. A quick check of basic performance statistics showed over 30% higher CPU consumption.

One of the most significant announcements of the entire conference to me was that of per-function concurrency control. Traffic shaping / canary deployment was pre-announced at Serverless Conf NYC in October, and this is now available. Like Lambda, API Gateway now supports canary deployment / traffic shaping.

The internet accounts for an estimated 3–4% of global emissions — equivalent to some countries. The carbon emissions of the internet are roughly equivalent to those generated by the entire aviation industry, or the whole of Africa. For example, changing our database architecture to be more efficient could save on server costs.
