“Too much cognitive load will become a bottleneck for fast flow and high productivity for many DevOps teams.” QAware | 7 ■ Intrinsic Cognitive Load Relates to fundamental aspects and knowledge in the problem space (e.g. used languages, APIs, frameworks) ■ Extraneous Cognitive Load Relates to the environment (e.g. console command, deployment, configuration) ■ Germane Cognitive Load Relates to specific aspects of the business domain (aka. „value added“ thinking)

Crossplane in a Nutshell ■ https://crossplane.io ■ Open Source Kubernetes Add-on. Universal Control Plane for Cloud Infrastructure. ■ Plattform Teams können mittels Crossplane die Cloud Infrastruktur Dienste unterstützter Provider zusammenstellen und über High-Level Self-Service APIs bereitstellen. ■ Cloud Infrastruktur Dienste können von Anwendungs-Teams deklarativ definiert werden ■ Provider bündeln eine Menge an Managed Resources und den dazugehörigen Controller. Alle gängigen Cloud Provider werden unterstützt, e.g. AWS, GCP, Azure, Alibaba, … ■ Managed Resources sind granulare, hochgenaue Crossplane-Repräsentationen einer Ressource in einem externen System. ■ Composite Resource Definitionen oder XRDs ermöglichen die Definitionen neuer Abstraktionen für zusammengesetzte Managed Resources. ■ Configurations und Packages erlauben die einfache Definition, Verteilung und Aktualisierung von XRDs und deren Abhängigkeiten.

Lerne uns bei einem online Schreibtisch-Workout kennen Meistens fängt man ja erst an, wenn‘s schon zwickt. Damit das gar nicht erst passiert, zeigt uns eine Trainerin von Besser Bewegen Übungen, die man in einer kleinen Pause am Schreibtisch machen kann, um die Rückenmuskulatur gezielt zu stärken, Schmerzen vorzubeugen oder zu lindern.
