Σημεία μάθησης

  • Το Frontend και το Backend συνδέονται χαλαρά μέσω Services.
  • Ο Redis Leader και ο Redis Follower χρησιμοποιούν ξεχωριστά Services για εγγραφές και αναγνώσεις.
  • Μπορείτε να αυξήσετε τα replicas του Frontend χωρίς να αλλάξετε τα Redis manifests.
  • Τα Probes και οι απαιτήσεις πόρων κάνουν το επίσημο βασικό παράδειγμα πιο κατάλληλο για workshop.
