My recollection is that for a period of time, as a part of the internal “Move to AWS” (MAWS) campaign, the entire retail business ran within a single VPC. A lot has changed!
- spwa4 1y agoThat's crazy. That would never work unless these are just a VLAN configured on existing switches. Even VXLAN wouldn't be able to do that 5 years ago.
