Rackspace's IaaS offering was never close to what AWS, Azure or even GCE offer.

It was more similar to DigitalOcean or Vultr, who are not really IaaS but VPS providers. I mean, where are the VPCs? the incredibly redundant load balancing? the VPN gateways, etc?

Disclaimer: It has been 2 years since I evaluated RAX's offerings.

Rackspace offers most of the services Amazon/Google/Microsoft does - but you're right, they did start out as Slicehost which is a Linode competitor (back in what...2009?)
