I am not sure how much of this is not already mitigated with https://serverless.com https://serverless.com. I have never used Lambda without it. For me serverless.com is the solution to avoid vendor lock in. However, Lambda is a tiny fraction of the entire stack we are talking about here. S3 + EMR + ALB + EC2 are all there and they are much more difficult to dodge the vendor lock in bullet with. One particularly sticky vendor lock in for S3 is pricing and reliability. Unfortunately it is almost impossible to beat that. My clients just discovered this, it would be significantly more expensive to move from S3 to HDFS or any other storage solution. This has nothing to do with how open the platform is, yet it is a much more serious lock in.
