4 - Microsoft SQL Server(DBaaS) server connection

Scenario Overview

The Microsoft SQL Server(DBaaS) server connection scenario is a scenario where a Bastion host (Virtual Server) and a Database service are created, and the DB service is accessed through the Bastion host. To securely access Microsoft SQL Server (DBaaS) in the Samsung Cloud Platform environment, it is necessary to create a Bastion host and use it for network connection. To maintain a stable and high level of security, it is recommended to configure the Database service in a Private Subnet environment and configure the Bastion host in a limited Public Subnet environment.

This scenario largely describes the process of creating a Bastion host and Database service, and configuring the network environment for Bastion host and Database connection, and accessing it through a DB connection client.

Scenario Components

You can configure the scenario using the following services.

Service Group	Service	Detailed Description
Networking	VPC	A service that provides an independent virtual network in a cloud environment
Networking	VPC > Subnet	A service that allows users to subdivide the network into smaller segments according to purpose/size within the VPC
Networking	VPC > Public IP	A service that reserves public IP and assigns and returns it to Compute resources
Networking	VPC > Internet Gateway	A service that connects VPC resources to the internet
Networking	Security Group	A virtual firewall that controls the server’s traffic
Database	Microsoft SQL Server(DBaaS)	A service that easily creates and manages Microsoft SQL Server in a web environment
Compute	Virtual Server	Virtual server optimized for cloud computing
Compute	Virtual Server > Keypair	Encryption file used to connect to the Virtual Server
