If you are a customer of Rackspace and utilize RackConnect technology, you may have encountered Rackspace specific terminologies while interacting with Rackspace via Ticket/Phone. This post will provide some of the terminologies and explanations:
“EDGE Device” is the outermost network device (Firewall or Load Balancer) in your infrastructure.
“CONNECTED Device” is the network device (Firewall or Load Balancer) that is connected to the Public Cloud infrastructure.
“RC Environment” refers to the combination of “EDGE” and “CONNECTED” device and the cloud account in a particular Data Center. A customer can have multiple “RC Environment” within the same DC or in multiple DC.
Example:
Customer A can have “Primary(LON)” and “Seconday(LON)” – 2 RC Environments (Primary & Secondary) in the same DC – LON
Customer B can have “Primary(DFW)” and “Secondary(LON)” – 2 RC Environments (Primary & Secondary) in 2 different DC – DFW & LON
