Aus Erfahrung gut

Kubernetes hat sich in den letzten vier Jahren zur Standardlösung für Container-Management entwickelt. Vor allem zustandslose Anwendungen, die lokal keine Daten speichern müssen, sind mit Kubernetes einfach zu betreiben. Datenbanken und andere Komponenten der Persistenzschicht werden jedoch oft weiterhin klassisch betrieben oder als Service bei einem Cloud-Anbieter hinzugebucht. Operatoren bieten unter anderem die Möglichkeit, auch zustandsbehaftete Software verlässlich auf Kubernetes zu betreiben.

Cross-platform testing of TypeScript code with Jasmine and Karma

I like TypeScript. Writing code that already underwent basic checks (i.e. typechecking) before it can even touch an execution engine is a big win in my book. In particular, TypeScript is nice because it integrates well into the broader JavaScript ecosystem and comes with batteries (i.e. types) included. Unfortunately, most test runners require extra setup to work with tests written in TypeScript. Some even require staggering amounts of configuration.
