### Using OpenVNet to safely test changes in complex production
networks
Making changes to a computer network running a production system
is often a very scary thing to do. A simple task such as updating
a firewall's firmware can have drastic consequences for the
correct operation of production critical services. Even if test
networks are set up, those are often much smaller in both size and
complexity, still making it hard to accurately predict the
complications of the change.
This is where OpenVNet
comes in. Using OpenVNet, it becomes possible to create
virtualized copies of highly complicated production networks using
only very limited hardware. This effectively enables us to write
automated test suites that deeply test and evaluate changes before
they are pushed to production.
During this presentation we will give a live demonstration where
we connect OpenVNet virtual networks to a physical Juniper SSG5
firewall. Assuming a production environment using the same
firewall, we can now create a virtual copy for testing.
