NoSQL Database and Hybrid Cloud Usage Scenarios at Rakuten Travel

Rakuten Travel uses many NoSQL databases in our service and all run in the private cloud in Rakuten. For several reasons, we wanted to use both private and public clouds. For example, high availability was fully achieved in the multi-region architecture but required securing physical resources. Today our document databases can be used in a hybrid cloud model (private cloud and GCP). This talk will share the background, verification, and use case, and highlight the benefits of using document databases in a hybrid cloud.
