Devices and networks have evolved too: Alex Russell @slightlylate An update on mobile CPUs and the Performance Inequality Gap: Mid-tier Android devices (~$300) now get the single-core performance of a 2014 iPhone and the multi-core perf of a 2015 iPhone. The cheapest (high volume) Androids perform like 2012/2013 iPhones, respectively.

In 2010, however, nearly none of it existed: the CNCF wasn’t formed until 2015! In this architecture, service to service communication no longer goes through the single point of failure of a load balancer. We had already developed a service mesh control plane that implements the Envoy XDS services.

In many organizations, front-end developers know exactly what common underlying problems are and what loading patterns should be used to fix them. So every time a conversation about further development happens, performance is a part of that conversation as well. Establish a performance culture. thanks, Guy Podjarny!
