“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)
The Platform team as a key enabler for high productivity of
stream-aligned DevOps teams.
QAware | 8
■ Responsible to build and operation a platform to
enable and support the teams in their day to day
development work.
■ The platform aims to hide the inherent complexity
to reduce the cognitive load for the other teams.
– Standardization
– Self-Service
■ Fully automated software delivery is the goal!

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. QAware | 10

QAware | 8 ■ Responsible to build and operation a platform to enable and support the teams in their day to day development work. ■ The platform aims to hide the inherent complexity to reduce the cognitive load for the other teams. – Standardization – Self-Service ■ Fully automated software delivery is the goal! https://hennyportman.wordpress.com/2020/05/25/review-team-topologies/

  • 10. 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.
