3 - CacheStore(DBaaS) Server Connection

Scenario Overview

Connecting to CacheStore (DBaaS) The scenario involves creating a Bastion host (Virtual Server) and a Database service, and accessing the DB service through the Bastion host. To reliably connect to CacheStore (DBaaS) in the Samsung Cloud Platform environment, you need to create a Bastion host and establish a network connection using it.
