Oracle Exadata Express Cloud Service is praised for its stability, top performance, and scalable cloud capabilities, setting it apart from its on-premise counterparts. Its modular design supports easy upgrades, and it is lauded for high availability without database changes. However, Oracle's pricing strategy, customer transition perceptions, marketing, support services, and tedious scaling process need improvement. Despite these challenges, Oracle Exadata Express Cloud Service remains highly recommended, consistently rated ten out of ten.
