I wonder if this is one of those strategic deals that would lead to an acquisition. With the push surrounding cloud and Google actively competing hard in this space, it would make a lot of sense.
It would fit in well with their silent yet never ending reach across the internet.

If google still doesnt think it has a marketable product after 4 years.. maybe a cloudflare acquisition isn't too far fetched.
