3 - CacheStore(DBaaS) server connection

Scenario Overview

Connecting to CacheStore(DBaaS) The scenario creates a Bastion host (Virtual Server) and a Database service, and accesses the DB service through the Bastion host. To reliably access CacheStore (DBaaS) in the Samsung Cloud Platform environment, you need to create a Bastion host and establish a network connection using it. To maintain stability and a high level of security, we recommend configuring the Database service in a Private Subnet environment and setting up the Bastion host in a restricted Public Subnet environment.

This scenario primarily describes creating a Bastion host and Database service, configuring the network environment for Bastion host and Database access, and connecting through a DB client.
