If LAN is legacy, what is the UN-legacy...?

What do you think about the fact that these SDNs aren't really free, yeah LANs aren't free you need a switch, but SDNs need a control node and switches and internet access.
ZeroTier is truly free and can be done without Internet access, if you want.

Are there other options?
The idea of the citadel (I call it this because the LAN was the castle) is that there is no "shared address range", or at least no dependency on it. Security is no handled by having a "safe zone" on which you put services, you assume all networks are suspect and secure data accordingly.
I think that there are two key elements to removing the LAN dependency and ideology:
- Secure everything as it everything was a suspect network.
- Publish everything so that there is not a "local" network addressing dependency for resolution.
-
I would love to read more about the idea of
but as the LAN becomes increasingly unnecessary I see "enterprise" very much not the term for this model. Enterprises are the ones best equipped to move to more modern structural models."
Any links to articles on the subject and concept

But if you are doing that, why bother with ZT?

If you are doing it for free? Just because you don't want to pay.
Without Internet? Because you want software defined networking. Same basic reasons for OpenDaylight.

Encryption is the first thing that comes to mind.

OpenDaylight? (searching internet)
If your network isn't attached to the internet, then why would you need SDN? What do you gain? I definitely see why you use SDN for internet connected devices/services...

most systems already have their own encryption built in, so that shouldn't be a problem.
Windows can run completely encrypted on the LAN side if you want - enable certs/keys, etc...

Right... and you are just building a complicated, proprietary SDN

My biggest concerns about having things like AD on Azure would be that traffic (encrypted or not) being hit by a MITM type attack. It makes your information more vulnerable to that, than if you were, say... Running your business infrastructure on ZeroTier.

Tell me how ZT makes you immune to a MITM?

Or at least less susceptible than Azure AD.

Azure AD doesn't have this issue because Azure AD assumes all networks are untrusted, and as such transmits data only in a secure/encrypted manner to the endpoint.
Now of course this doesn't mean it's impossible for a MITM to get in there, its much more difficult.
ZT is really only useful for systems that don't have their secure communication method already in place. And example would be traditional LAN based AD. By default this communication is not encrypted, so using ZT would provide a level of protection that the LAN does not, while at the same time enabling you to be much more mobile at the same time.

Less susceptible is definitely a better way of stating that.

This is an interesting concept. Does anyone have any documentation on this? I'd love to read about what it would take to actually implement something like this.

Sadly, no. But it is coming soon
You heard it here first!! -
Oh, we could do a case study pretty easily, though. @ntg does this and has kind of stepped through the "best of breed" network design for a modern company over the years so we are good for that.
I've worked at several companies that have done this, as well, so I have some decent insight into what others are doing, not just one company.

@scottalanmiller I have a serious lack of knowledge that I am fervently attempting to make up for so please excuse any misinformation.
Currently we are set-up with a primary Domain and a VM secondary replicated domain at the same site (as well as a few remotely replicated domains for our bigger sites). A file Server, SQL Server using Financial Edge/Blackbaud, A terminal server for remote sites to access e-mail as well as the Network Share, etc. My question would be how would Active Directory look with this? I'm assuming I would I be able to actually connect all of my remote sites to a remote domain with something like this and everything would be managed through the cloud?
Any information at this point is very appreciated
Thank you as always. -
@wirestyle22 I'd like to take a crack at this.
There are three approaches that I can currently see for you.
- LAN/WAN (VPN or dedicated site to site links) to connect all devices "privately" - what you are doing today.
- Pertino/ZeroTier - this would involve installing Pertino/ZT on every device in your environment and using that network to interconnect all of your equipment. The physical network is more or less a way for devices to get on the internet (yes I'm making an assumption here that the SDN will work on the internet) so they can connect to the SDN.
- Use something like Azure AD (only supports Windows 10 endpoints) and other services (OwnCloud/Office 365/DropBox, etc) that assume connections are all coming from untrusted sources and acts according.
-
@Dashrender That makes a lot of sense. Thank you.
Wouldn't every piece of software (especially Financial Edge/Blackbaud--SQL) need to support that? Also, how is this going to access files and run queries? Is it still going to be based on the Local IP/Mac Address or is it going out and then back in? I'm sorry if these are stupid questions.
