Similar to IBM, Oracle had enterprise customers as it's focus. It offers Kubernetes and Docker hosting, just like the others, and so autoscaling and monitoring are mostly a matter of configuration.

All in all, almost every competitive cloud provider will offer autoscaling capabilities, as well as the related monitoring services. The choice of whom to choose comes mainly down to preference and budget. The prices vary, and you should consider the long-term effect. But overall, all providers are stable and reliable enough to host and scale your application.
