The following diagram depicts Session Manager bastion access to SQL Server in a private subnet. This also means your bastion host is in a public subnet, and open on port 3389 to accept remote desktop connections. If these are Windows-based hosts, which is common in large organizations, you need to manage the RDP session limit of a non-terminal server, or license it accordingly. You need multiple hosts to be shared among the teams.

In this scenario, you have the required GUI toolsets installed on the bastion host and can start or stop the instance as needed. The following diagram illustrates RDP/SSH bastion access to SQL Server in a private subnet. To allow your database administrators, engineers, and development teams to have access, it’s common to use bastion hosts. In the case of databases, this allows you to lock down your databases to only those users and applications that need access. It’s best practice to host critical infrastructure in restricted subnets. In this post, I show you how to use AWS Systems Manager Session Manager to securely connect to an RDS instance from your own workstation. Some company policies don’t allow this in any case, because this requires remote access ports to be open from a public subnet into a private or restricted subnet hosting critical infrastructure such as databases.

You also don’t have direct access to it or access to RDP or SSH to it from a public subnet. With Amazon Relational Database Service (Amazon RDS), the OS layer is managed and maintained by AWS, so you don’t have to worry about monitoring it, patching it, or recovering it in the event of failure. They’re feature rich, provide snazzy functionalities such as being able to right-click and view script object definitions (for example, tables to a query window), provide graphical real-time views on what’s happening in your databases, and generally shorten the learning curve if you’re new to a particular database engine. This blog post was last updated July 2022, to reflect the new RemoteHostPortForwarding feature of AWS Systems Manager Session Manager.ĭatabase professionals have used GUI-based tools for many years.
