Currently setting up a bakery and have the following architecture in mind.
Four public nodes running on four different datacenters on two different clouds
Two nodes running in private mode connected only to the four public nodes, also in the cloud
Baker, endorser and accuser running on 1 of the private nodes and the same stack on "hot standby" on the other
Both bakers using the same remote tezos-signer
A tezos-signer daemon running on a local laptop (because battery) with a ledger and two internet connections (fiber + 4G)
All nodes connected via a SDN/VPN
What does the community think about this setup? Sounds like a decent HA setup for a medium sized bakery? Any glitches? Overkill?
Feedback much appreciated 😬👍

Looks like a good start.
Unless your (4G)-router has a battery consider an uninterruptible power source (UPS).
A second laptop with signer and additional ledger on standby in a separate location close by will improve HA in case of hardware problems, fire/water damage or a prolonged power outage.
Probably more important is your software setup. Does the node/baker/signer software run as a service so it will start again in case of a restart? Here is a great guide to do this:
