From Java to Jenkins to Kubernetes to OpenTelemetry, the world of technologies impacting our development and delivery is constantly changing. While not every technology makes it to the big show, recognizing which ones will have an impact on you is key to keep your technology knowledge sharp. Dave McAllister, OSS Technical Evangelist for NGINX, dive into some nascent technologies that are very likely to have near- and long-term impact on the way he approaches code and operations. Providing insights and opinions on the direction of Kubernetes and OpenTelemetry, he also look into cool stuff like WebAssembly and eBPF, and touch on how development has to change to create the future.
