TechCrunch notes from Snap’s filing that Snap are committing to spend $2B with Google over the next 5 years on Cloud Infrastructure.
$400M per year isn’t big compared to Google’s other revenues (from ads), but it shows the growth coming. Similar to how Apple’s watch business is tiny compared to the iPhone sales, but is huge compare to other global companies eg Rolex (Apple Watch outsold Rolex in its first 12 months: $6B compared to Rolex’ $4.5B).
It’s easy to lose sight of how big dollar numbers can be.
