This is the benefit of running on GCP. We don't have to trouble ourselves with the headache of scaling both with the images and containers thanks to the internal tools offered by GCP.
We quit Softlayer around February. We were running bare metal and they went down so often that we essentially ended up keeping one super large server for a very insignificant service. We never gave them too much of chance so I may be too harsh.
I stopped thinking about bare metal a while ago. I'm thinking about the comparison with AWS and I see that your entire business is relying on capabilities only available on Google Cloud (which indirectly, is why I'm advising Google Cloud nowadays. It's easier for basic usage and it's unlocking a whole new set of extreme usage).
Things you couldn't have pulled off on AWS that easy: Create thousands of hosts, deploy images that fast, managed kubernetes, pubsub, worldwide AMI, multi region subnets.
