To put that into perspective - if the rate continues for 4 years (doesn't seem that unbelievable) - revenue would be ~$24Bn - which is close to FB currently...
I am more surprised by having such stunning growth by many big tech without actually having any new businesses. It used to be that 10% growth was a lot and now people scoff at even 30%.
This is not 100% new business. It displaces existing one - on-premises, company owned datacenters and colocations. Just as electric cars are growing fast because they are eating into ICE market.
I don't know how many others think like I do, but I'd never use GCP. No one will ever convince me that it'll be around in 5 years. I just don't trust them to keep anything they made in the past decade or so going long term. Call me paranoid, call me whatever you want, but I just do not trust their ability to focus on anything anymore.
