Google sucks at productizing their infrastructure expertise. The underlying tech at Google is indeed better than CloudFlare, but CloudFlare understands marketing, ease-of-use, product simplicity, all those stuff that are necessary to get people to actually use your offering.
I was amazingly surprised by Google Compute Engine. I've never used such a simple IaaS provider. Especially compared to the direction Azure's new portal is taking, GCE is refreshingly simple. EC2 is alright but still feels a lot more complicated than GCE. The UI is simpler, too.
I don't think they need CloudFlare for that though, they just need marketing people to sell it. I can't see CloudFlare acquisition being worth it for Google just for their marketing expertise.
