RackConnect v1.0 is the very 1st version of RackConnect and it provides simple connectivity between the Dedicated, Single Tenant Environment and the Cloud Servers via ServiceNet.
After a cloud server is spun up, manual changes would have to be made to the cloud server’s route table, interface and software firewall/iptable in order to force the traffic to flow to dedicated servers.
RackConnect v2.0 is the next iteration of the RC product series. The major advantage of RC v2 compared to RC v1 is Automation. Changes to route table, cloud server interface, software firewall/iptable and IP assignment were taken care by the automation. RC v2 was also essential for utilizing the next generation “performance cloud servers” offered by Rackspace.
RackConnect v2.1 is similar to RC v2 but consists of RC v1 configurations that were migrated to RC v2.
RackConnect v3.0 is the latest in the RackConnect series. RC v3 utilizes SDN & Cloud Networks while the previous versions utilized the ServiceNet network offered for access to the different “Services” provided within the Datacenter.
Comparison of RC v3 & RC v2 is seen here.
As of Q4 2014, new customers will be provided with RC v3 features. There are quite a few customers on RC v2 and RC v2.1. RC v1 is almost non-existent.
