I think that vendor lock-in on a cloud is more about reliance on technologies designed for a specific cloud. AppEngine, DynamoDB, or Cloud Formation being examples. To avoid lock in, use technologies like Kubernetes, MongoDB, or Terraform instead. That way jumping clouds is at least possibly without a rewrite.
