Earlier quoted context omitted.
I don’t think it’s commoditized. AWS has moved past being just EC2. Virtualization is a small piece or the picture, and building and operating DynamoDB or S3 or SQS are all very tough tasks.
It's not commoditized at the scale Amazon operates it at. And from an AWS / profit perspective, running the rest of Amazon is essentially what gives them a base consumer to get them to that scale.
It's that aggregate of so many individual clients that makes it difficult. So why aren't all the small clients getting picked off by the hundreds of small competitors?
My take is that the sheer scale of AWS has hit a point where engineers (the ones making infrastructure decisions) and moving from one company to another are just more likely to be familiar with AWS at this point. The same concept makes hiring easier.
My other guess is that lots of engineers are like me and just got sick of their hosting company getting bought out and constantly having to deal with console changes and migrations.
I am with GCP now, one of the reasons I picked GCP is because they are very large and have reasons to continue offering cloud services even if it becomes commoditized and unprofitable. The same is true for AWS.
Also, of course "no one ever got fired for choosing AWS".
