re: Both GCP and AWS offer virtual private networks to interconnect your machines. However, all data going through that network is sent as is, logicall...

Hi david,

First of all, sorry for the misunderstanding if that wasn't clear.

  1. About networking, we're referring to private networks between your servers here. Not VPNs, but private networking. It's virtual because you don't have a cable connecting your computers, and here is where the risk lies: data is transmitted over the same cable together with other customers, the only separation is virtual. If an attacker had access to the raw data in the cable, they would be able to see your traffic, given it's not encrypted.

  2. About Redis: Redis stores data on disk on most configurations (including the default configuration in AWS). Actually, the key difference between Redis and other databases is that it defers the writing to disk, so this doesn't block the read/writes. Same applies to database backups.
