"I wouldn't underestimate how... having one company as both your registrar and cloud service provider can impact the choice of which otherwise commodity service to use." THIS. Even if I'm just spinning up a simple blog, unless I'm buying a premium domain name, I'm gonna buy it on Bluehost instead of a cheaper registrar like Namecheap just to avoid the few minutes of work and few hours of wait time to link that domain with another hosting service.
