Brutal.
One thing I always wondered was why Facebook never started their own cloud services offering like Amazon did with AWS? They have the scale, expertise, and infrastructure to do it yet never have.
While a lot of large companies constantly churn through new product ideas to see what sticks, Amazon hit a home run early on with AWS, and Facebook could have easily started their own many years ago when it was clear how the market was developing for cloud.
