as you scale up your clusters: etcd nodes operated by the etcd-operator will not use persistent storage. Once the etcd cluster looses quorum, the etcd cluster is automa�cally re- created by the cilium-etcd-operator performance, distributed memory object caching system. It’s simple yet powerful, and used by dynamic web applica�ons to alleviate database load. Memcached is designed to work efficiently for a very large PRODUCTPAGE_URL=${GATEWAY_URL}/productpage $ echo "Open URL: ${PRODUCTPAGE_URL}" Open that URL in your web browser and check that the applica�on has been successfully deployed.
