This could be any other private resource in OCI with a private IP.

Exadata Cloud Service virtual machine in OCI with a private IP (10.0.2.2).

The private resources could be Compute VM instances, databases using the virtual or bare metal DB systems, or Exadata Cloud Service virtual machines. OCI Bastion service eliminates the need for deploying public subnets or jump servers and provides an easy way to build SSH connections to private resources in OCI.

You have to take care of securing the jump sever instance adding more administrative work.

You have to create and maintain further resources: public subnet, Internet Gateway, Security List, etc.

Creating an instance with a public IP might violate your organization’s security rules.

One way to do so is to provision a compute instance in a public subnet and use it as a jump server. Another use case is when you are outside of your organization’s network and need access to private resources. However, when you start a PoC and that connection is not yet set up and you are ambitious to start trying things out, you’ll need a way to connect to those private instances, where application servers or databases.

To log in to the private machines for management purposes, customers will have to set up their private connection to Oracle Cloud via VPN or FastConnect. End users will access applications via a load balancer. Databases and even application servers in the Cloud are usually provisioned in a private subnet that is not accessible from the internet.
