Nothing leads into Web shop. Nothing leads out of Search index, Orders and Payment provider. Bottleneck: API gateway; without it the diagram falls apart. Heaviest connection: Web shop → API gateway (1200). Web shop (frontend): connects to API gateway (1,200/s, weight 1200). API gateway (service): connects to Catalog (820/s, weight 820), Cart (310/s, weight 310) and Checkout (70/s, weight 70). Catalog (service): connects to Search index (640/s, weight 640). Cart (service): connects to Orders (150/s, weight 150). Checkout (service): connects to Orders (60/s, weight 60) and Payment provider (35/s, weight 35).
