Lernpunkte

  • Frontend und Backend werden über Services lose gekoppelt.
  • Redis-Leader und Redis-Follower haben getrennte Services für Schreib- und Lesezugriffe.
  • Das Frontend kann skaliert werden, ohne Redis-Manifeste zu ändern.
  • Probes und Ressourcenanforderungen machen das offizielle Minimalbeispiel workshop-tauglicher.
