If a company is going from zero to something, then you are absolutely right. In that case, dealing with vendor lock in later means success!
If an established company is moving to the cloud, the equation is not as simple. The established company presumably has the money and time to make their vendor agnostic. Is the vendor lock in risk worthwhile to spend more now? How large is the risk? What are the benefits (using all of the AWS services is pretty nice)?
>"benefits (using all of the AWS services is pretty nice)"
your personal experience? Or are you simply assuming that interop / efficiencies obtain when going all-in on AWS? I ask, because I've had multiple client conversations in which these presumed benefits fail to materialize to a degree that offsets the concern about lock-in.
I can't claim to have used all of the AWS services, but whenever I need something done I check if it's offered in AWS first. SQS,SNS,ECS,ALB/ELBs,SFNs,Lambdas, media encoding pipelines, Aurora RDS, etc... have all made my job easier.
