Virtual Server Connectivity Isolation

How can a given virtual server be isolated and prevented from communicating with the external network while remaining in contact with other virtual servers and resources?

Problem

A virtual server’s communication needs to be limited to only the virtual server and other resources it needs to remain in contact with, and isolated from all other parts of the external network.

Solution

The virtual server is not allowed to connect to any part of the solution that has a communication path to the external network or internal network, outside of what is required.

Application

The virtual server is isolated via the use of an additional virtual switch, thereby isolating it from the traffic of other virtual servers.

Mechanisms

Hypervisor, Physical Uplink, Virtual Firewall, Virtual Infrastructure Manager, Virtual Switch

Compound Patterns

Burst In, Burst Out to Private Cloud, Burst Out to Public Cloud, Cloud Authentication, Cloud Balancing, Elastic Environment, Infrastructure-as-a-Service (IaaS), Isolated Trust Boundary, Multitenant Environment, Platform-as-a-Service (PaaS), Private Cloud, Public Cloud, Resilient Environment, Resource Workload Management, Secure Burst Out to Private Cloud/Public Cloud, Software-as-a-Service (SaaS)

Virtual Server B is given its own virtual switch, so that it can be completely isolated from all other virtual servers besides Virtual Server A.
