Sorry for being late to the party. 'in theory' couldn't we do away with the idea that 'advanced networking with security groups' is a type of zone and just allow the use of security groups in any network, instead of making people 'choose' up front. I believe AWS allows the use of security groups in VPCs. It seems a little 'belt and braces', but I know of users who have looked to do it.

This provides (from what we can see) all the features Basic Networking provides, like the VR just doing DHCP and UserData while the Hypervisor does the Security Grouping. That made me wonder why we still have Basic Networking. Dropping all the code would be a big problem for users as you can't simply migrate from Basic to Advanced. In theory we found out that it's possible by changing the database, but I wouldn't guarantee it works in every use-case. So doing this automatically during a upgrade would be difficult. To prevent us from having to maintain the Basic Networking code for ever I would like to propose and discuss the matter of preventing the creation of new Basic Networking zones. In the future this can get us rid of a lot of if-else statements in the code and it would make testing also easier as we have few things to test. Most of the development also seems to go in the Advanced Networking direction. We are currently also working on IPv6 in Advanced Shared Networks and that's progressing very good as well. Would this be something to call the 5.0 release where we simplify the networking and in the UI/API get rid of Basic Networking while keeping it alive for existing users? Wido
