It's less about brand awareness and more about telling customers upfront what it does. If I'm an Akamai customer that's never heard of Linode, maybe I ignore "Akamai Linode" because I've no clue what it does. If I hear "Cloud Computing Services", I know exactly what that offering is likely to entail from the name alone - Compute as a service.

The downside with this approach is that you lose any brand awareness of Linode. Perhaps that's not a terrible thing if their market share was minimal. You could have gone with "Akamai Linode Cloud Computing Services" or "Linode Cloud Computing Services by Akamai". But Linode seems a bit redundant in that name to my eyes.
