A large part of the issue with pricing on Google App Engine (which is the one that still stings for many people) - was that they were building on a relatively proprietary platform.

The advantage of Docker based compute engines is that your lock-in is a lot lower - providers have to compete on price and features without locking customers in.

Where I work, we're always balancing using new AWS features against how hard it would be to migrate out to another provider or take our solutions on-premises.
