Yes, but this is common for "cloud native" applications. Web servers are ideally stateless "cattle", not "pets". Code is pulled down via CI/CD pipelines or via container images. State is in databases or blobs. Logs stream to some sort of analytics system.

Similarly, Kubernetes works well with spot VMs. You can have Spot and Regular node pools in one cluster, and then your workloads can happily spread out to the extra capacity at a huge discount.

It's really easy to "beat" the chaos monkey with this kind of design. You can destroy any VMs in our infra with reckless abandon and everything will be fine. If you destroy all the VMs of particular service obviously it will affect availability but it will still recover by itself in about 60 seconds.
