Slight oversimplification, but Google's had basically S3/GCS and Hadoop since early 2000s, and basically Docker + Kubernetes for the past 10. This translates into real-world edge.
For example, how many big data tools have any one of the 15 characteristics of BigQuery that I described at [0]? Or how many companies have inter-data center networking that gives you a Petabit of bisectional bandwidth, described at [1], or how many cloud providers have live migration, custom VMs, or insane RAM-like local SSD? Or how many PaaS offerings can sustain a behemoth like Snapchat? Or a NoSQL that scales to 56 million qps with just a handful of engineers [2] ??
Edit: To add more color. In days past, Google would release papers (GFS, MapReduce, Bigtable, etc). With Google Cloud Platform we can just externalize these services (with a bit of customer-friendly bits like isolation, pricing, etc). Bigtable, BigQuery (Dremel), PubSub to name a few.
(clearly biased, since I work at Google)
